#	Lesson	Hr	Type	Objective	Activities	Materials	Check
1	PV Jobsite Safety: OSHA 10-Hour Construction Core	32	theory	Students will identify and explain the OSHA 10-hour construction safety topics as they apply to residential and commercial PV installation worksites, including fall protection, electrical hazards, struck-by hazards, and heat illness prevention.	Work through each OSHA 10 construction module using the OSHA outreach curriculum; for each topic, students identify at least two PV-specific hazard scenarios (e.g., working at roof eave, energized DC circuits) and record them in a personal hazard log. Participate in a table-top scenario exercise: given a photo of a residential rooftop worksite with planted hazards, students complete a written Job Hazard Analysis (JHA) form identifying hazards, affected workers, and selected controls using the hierarchy of controls. Role-play a pre-work toolbox-talk in groups of four, with one student leading a five-minute safety briefing on fall-protection requirements (OSHA 29 CFR 1926 Subpart M) while others play crew members and ask clarifying questions; instructor evaluates using a checklist.	OSHA 10-hour construction outreach curriculum (current edition), OSHA 29 CFR 1926 Subpart M fall-protection regulations, JHA blank forms, sample rooftop site photographs, personal protective equipment (hard hat, safety glasses, gloves, high-visibility vest) for demonstration, OSHA outreach completion cards reference sheet	Students submit a completed JHA for a provided rooftop PV scenario; rubric requires correct identification of at least four distinct hazard categories, an appropriate control for each using hierarchy of controls, and no critical omissions (unguarded roof edges, unprotected energized circuits). Pass mark: 80% on rubric. Additionally, students must complete all OSHA 10 contact hours to receive the OSHA 10-hour construction card.
2	Electrical Safety, Lockout/Tagout, and First Aid/CPR for PV Work	20	lab	Students will apply OSHA electrical safety requirements and lockout/tagout (LOTO) procedures to PV-specific de-energization tasks, and will demonstrate adult CPR and first-aid response to electric shock and heat emergencies.	Demonstrate a complete LOTO sequence on a simulated PV training board (AC and DC disconnect switches, inverter, utility disconnect): students verbally narrate each step—notify, shut down, isolate, lockout/tagout, release stored energy, verify—while the instructor evaluates against a LOTO checklist drawn from OSHA 29 CFR 1910.147 principles as applied in the construction context. Practice using a digital multimeter to verify absence of voltage on the training board after LOTO: students measure AC and DC test points, record readings, and sign off that the circuit is at zero energy state before proceeding with a mock connector task. Complete a hands-on adult CPR and AED training session and basic first-aid for electric shock (do-not-touch protocol, emergency call, recovery position) and heat illness (shade, hydration, cooling) delivered by an instructor holding a current CPR/first-aid instructor credential; students must pass the skills check to earn a CPR/first-aid completion card.	PV electrical safety training board with AC and DC disconnects (deenergized training unit), personal locks and tags (one per student), digital multimeters (one per pair), test leads, voltage alert pen, AED trainer unit, CPR manikins (one per two students), first-aid kit for demonstration, OSHA 29 CFR 1910.147 reference excerpt, CPR/first-aid curriculum from an accredited provider	LOTO skills check: student performs complete LOTO sequence on the training board with zero critical steps missed; instructor initials each step on the LOTO verification form. CPR/first-aid skills check: student passes the hands-on skills evaluation per the CPR provider's standard. Both checks must be passed; either may be retried once within the lesson block. Pass mark: 100% on LOTO critical steps; CPR provider pass standard for skills check.
3	Trade Math for Solar PV: Arithmetic, Algebra, and Unit Conversion	24	theory	Students will solve trade math problems involving whole numbers, fractions, decimals, percentages, ratios, unit conversion between imperial and metric systems, and algebraic manipulation of Ohm's Law and the power equation (P = IV) as they arise in PV system sizing and wiring calculations.	Complete a structured set of 30 graduated practice problems drawn from real PV contexts: converting watts to kilowatts, calculating percent efficiency loss, converting feet to meters for string-length estimation, and solving for current given power and voltage—students self-check against an answer key and flag problems they could not solve independently for instructor review. In pairs, use a scientific calculator to work through a simplified PV module string worksheet: given module Voc, Vmp, Isc, and Imp values from a real specification sheet, calculate total string voltage at various temperatures using a provided temperature coefficient, and determine whether the string voltage stays within a sample inverter's MPPT range—record results in a formatted calculation sheet. Play a timed unit-conversion relay game in teams of four: each student receives a card with a measurement in one unit (e.g., 2.4 kW) and must convert it correctly (e.g., to watts, BTU/h, or amps at 240 V) before passing to the next player; instructor tracks accuracy and speed to reinforce fluency.	Scientific calculators (one per student), trade math workbook or instructor-prepared problem sets referencing PV contexts, real PV module specification sheets (at least two different modules), unit conversion reference card, whiteboard and markers for worked examples, answer keys	Graded 25-question math quiz covering all topic areas in the lesson; problems are drawn from PV contexts identical in style to practice sets. Pass mark: 75% (19/25 correct). Students scoring below 75% complete targeted remediation problems and retest within one week.
4	Measurement, Geometry, and Roof-Pitch Trigonometry for PV Layout	18	lab	Students will measure lengths, areas, and angles on physical and drawn surfaces using hand tools and a scientific calculator, and will calculate rafter length and usable roof area for PV array layout using rise-over-run roof pitch and basic trigonometry.	Using a tape measure and speed square, measure a full-scale mock roof section (constructed on the floor or a low ramp) to determine ridge length, eave length, and pitch; record measurements and use the pitch to calculate actual rafter length and gross roof plane area using the slope-area factor method, comparing results to a known answer within ±2%. Given three different architectural drawings at varying scales (1/4 in = 1 ft and 1/8 in = 1 ft), use an architect's scale rule to measure room dimensions and transfer them to a roof layout sketch; calculate net available roof area after applying a simplified setback (no specific code setback is assumed—a generic 18-inch perimeter setback is used for the exercise) to determine how many 400-watt modules will fit. Work through a trigonometry mini-lab: using a clinometer (or smartphone inclinometer app), measure the angle of inclination of a tilted board at three preset angles, then use sine and cosine functions on a calculator to find the horizontal run and vertical rise; compare calculated values to physical measurements made with a tape measure and verify agreement within ±5%.	25-foot tape measures (one per pair), speed squares, architect's scale rules (one per student), clinometers or smartphones with inclinometer apps, scientific calculators, printed architectural drawings at two scales, mock roof section or tilted ramp, chalk line, pencils and graph paper, slope-area factor reference table	Students submit a completed roof-layout worksheet for one provided drawing showing: scale measurements, area calculation, setback deduction, module count, and trigonometric pitch verification. Instructor checks math and layout logic. Pass mark: all five elements present and area calculation within ±5% of instructor-computed answer.
5	Reading Technical Documents: Drawings, Spec Sheets, and Manuals	20	theory	Students will locate and extract required installation data from PV single-line diagrams, mechanical roof-plan drawings, module specification sheets, inverter datasheets, and manufacturer installation manuals.	Given a complete residential PV permit drawing set (single-line diagram, site plan, roof plan, placard), students complete a document-reading scavenger hunt: answer 20 specific questions such as 'What is the inverter model number?', 'How many modules are in each string?', and 'What gauge wire is shown on the homerun?'—answers must be traced to the exact drawing or document page. Decode a real PV module specification sheet: students identify and record STC ratings (Pmax, Voc, Vmp, Isc, Imp), temperature coefficients, mechanical dimensions, and UL listing information; they then answer a set of design-relevance questions (e.g., 'What is the maximum system voltage this module is rated for?') to practice applying spec-sheet data. In small groups, follow a one-page excerpt from a real inverter installation manual to trace the required torque specifications for AC and DC terminal connections, identify the warning icons and explain what each means, and list the required conduit entry dimensions—groups present findings to the class in a two-minute summary.	Sample residential PV permit drawing set (single-line, site plan, roof plan — from a publicly available utility or AHJ example or an instructor-prepared set), real PV module specification sheets (two or more models), real inverter installation manual excerpt, document-reading scavenger-hunt worksheets, highlighters, rulers	Scavenger-hunt worksheet scored for accuracy: 18 of 20 questions answered correctly with page/section citation. Spec-sheet decode form scored: all six data fields correctly recorded and design questions answered correctly. Pass mark: 80% combined across both scored items.
6	Digital Tools, Solar Resource Data, and Project Documentation	18	demo	Students will use at least one industry-relevant solar resource mapping tool to retrieve site irradiance data, and will create and organize a basic PV project documentation package using a digital platform.	Instructor demonstrates how to use a publicly available solar resource tool (such as the NREL PVWatts Calculator) to input a site address, system capacity, tilt, and azimuth, and read the resulting energy estimate and monthly production table; students then repeat the process for two assigned addresses in different climate zones and compare results, recording findings in a structured data table. Students create a digital project folder for a sample PV job using a shared platform (Google Drive, Microsoft OneDrive, or similar available tool) organized into subfolders mirroring real workflow: Permits, Design, Inspection, As-Built; they populate each subfolder with provided sample documents, rename files using an instructor-prescribed naming convention, and share the folder with the instructor for review. Complete a short digital-literacy drill: given a PDF of an equipment datasheet with a URL for the manufacturer's website, students navigate to the site, locate the current version of the same datasheet, identify one specification that changed between versions, and write a two-sentence summary of the significance—this mirrors the real-world skill of checking for current equipment documentation.	Computers or tablets with internet access (one per student), NREL PVWatts Calculator (nrel.gov/pv/pvwatts), access to Google Drive or Microsoft OneDrive, provided sample project documents for filing exercise, two printed datasheets from different publication dates for the same product (instructor-prepared), headphones if needed for screen-share demonstration	Students submit their completed PVWatts data table (two sites) and a screenshot of their correctly organized digital project folder shared with the instructor. Instructor checks: correct PVWatts inputs and outputs recorded, folder structure matches template, files correctly named. Pass mark: all required fields present and folder structure 100% correct; PVWatts values within acceptable rounding of instructor's answer.
7	Career Readiness, Professional Communication, and NABCEP Credential Pathways	16	theory	Students will produce a personal career plan that identifies employment targets in the solar industry, maps the NABCEP PV Associate and NABCEP PV Installation Professional credential requirements to their program coursework, and demonstrates professional communication skills through a resume draft and a mock employer interaction.	Research two local or regional solar employers (using company websites, LinkedIn, or job-posting sites), document the job titles they post, the credentials and experience they require, and the starting wage ranges listed; compile findings in a one-page employer-research summary and discuss as a class which skills and credentials appear most frequently—this grounds the credential pathway discussion in real labor-market data. Using the current NABCEP PV Associate and NABCEP PV Installation Professional candidate handbooks (downloaded from nabcep.org), students map each program course to the relevant NABCEP exam content domain on a provided grid, then write a two-paragraph explanation of when they plan to sit each exam and what eligibility documentation they will need to gather (e.g., logged installation hours for PVIP). Draft a one-page resume tailored to an entry-level solar installer position, including a skills section that references safety credentials (OSHA 10, CPR/first aid) and any relevant experience; participate in a five-minute mock employer phone screen with a partner using a provided question set (safety attitude, reliability, willingness to learn), then swap roles and provide structured feedback using a peer-evaluation rubric.	Computers or tablets with internet access, current NABCEP PV Associate and PV Installation Professional candidate handbooks (downloaded from nabcep.org—no cost to download), credential-pathway mapping grid (instructor-prepared), resume template, mock phone-screen question set, peer-evaluation rubric, sample solar industry job postings	Students submit: (1) employer research summary meeting the one-page requirement with at least two employers documented, (2) completed NABCEP credential-pathway mapping grid with all program courses assigned to at least one exam domain, and (3) resume draft. Instructor evaluates resume using a rubric covering completeness, professional format, and accuracy of credentials listed. Pass mark: all three items submitted; resume rubric score ≥ 75%; credential mapping grid completed with no courses left unmapped.

#	Lesson	Hr	Type	Objective	Activities	Materials	Check
1	Solar Resource and Site Assessment	12	field	Students conduct a field site assessment, recording roof geometry, orientation, tilt, and shading data, and retrieve local solar resource values from NREL PVWatts or equivalent, demonstrating measurement accuracy within ±5° for azimuth and ±2° for tilt.	Measure and sketch a mock rooftop (or training facility roof) using a tape measure, compass, and inclinometer; record all dimensions, azimuth, and pitch on a standardized site-survey form. Use a Solar Pathfinder or equivalent shading tool (or the software simulation equivalent) at three locations on the mock array area and record sun-path obstruction data for each point. Log into NREL PVWatts, enter the site ZIP code and recorded tilt/azimuth values, and compare default versus measured inputs to observe how small orientation errors affect annual kWh output estimates.	Tape measure, compass, digital inclinometer, Solar Pathfinder or Solmetric SunEye (or instructor-provided shading simulation data), NREL PVWatts online tool, site survey forms, personal protective equipment per Course 1 requirements, hard hats if on actual roof	Completed site survey form reviewed by instructor; azimuth reading within ±5° of instructor reference, tilt within ±2°, and shading report that identifies at least the dominant obstructions. Pass = all three measurements in tolerance and shading report accepted by instructor.
2	Understanding Solar Modules: Ratings, Specs, and Electrical Behavior	10	theory	Students interpret a manufacturer datasheet and calculate module Voc, Vmp, Isc, and Imp corrected for local temperature extremes, producing values that match instructor-calculated answers within 2%.	Read three different module datasheets (monocrystalline, polycrystalline, and thin-film) and complete a comparison table listing STC ratings, temperature coefficients, and mechanical specs for each. Using the temperature correction formulas from the NABCEP study guide, calculate corrected Voc at the lowest expected ambient temperature and corrected Vmp at the highest expected operating temperature for a given module at a given site. Small-group discussion: explain why Voc at low temperature is the critical value for string sizing versus inverter maximum input voltage, and document the reasoning in a short written explanation (one paragraph).	Manufacturer datasheets (at least three module types), NABCEP PV Associate Study Guide, scientific calculator, temperature correction worksheet, whiteboard	Temperature-corrected Voc and Vmp calculations on the worksheet; values must be within 2% of instructor answer key. Pass = both corrected values within tolerance and written explanation demonstrates correct reasoning.
3	System Sizing: Loads, Array Power, and String Configuration	14	lab	Students size a complete residential grid-tied PV system—array wattage, number of modules, and string configuration—for a given utility bill and site, producing a design that meets string voltage and current limits for the selected inverter.	Given 12 months of a sample utility bill, calculate the average daily kWh load and use the site's peak sun hours from the previous lesson to determine the required array DC nameplate wattage, applying a standard derate factor. Select a module and a string inverter from a provided equipment list; calculate minimum and maximum string lengths using temperature-corrected Voc and Vmp values versus the inverter's MPPT voltage window and maximum input voltage. Configure the array (number of strings, modules per string) to meet the target wattage without exceeding inverter limits; document the configuration on a string sizing worksheet and verify with instructor before proceeding to drafting.	Sample utility bills (instructor-prepared), module datasheets, inverter datasheets (minimum two inverter models), string sizing worksheet, scientific calculator, NABCEP PV Associate Study Guide sections on system sizing	Completed string sizing worksheet reviewed by instructor; array size within 10% of instructor-calculated target, string voltage within inverter limits (no exceedance of max input voltage at low temperature), current within inverter input current rating. Pass = all three criteria met.
4	PV Design Software and Energy Production Modeling	12	demo	Students use a PV design software platform (PVWatts, Aurora, or instructor-designated equivalent) to build a system model for a given site and load, generate an annual energy production report, and interpret the results to confirm the design meets the client's offset target within ±10%.	Instructor demonstrates full workflow in the chosen software: site location, roof plane definition, module and inverter selection, shading entry, and report generation—students follow along on individual workstations entering the same project data. Students independently model a second practice project from a new site survey handout, adjusting array layout and tilt to maximize production while staying within the roof boundary, then export the production report as a PDF. Compare software-generated annual kWh to the hand-calculated estimate from Lesson 3; document the percentage difference and write a two-sentence explanation of why the values differ (e.g., detailed shading, soiling, or inverter clipping losses).	Computer workstations with internet access, PVWatts (free, NREL) or instructor-licensed Aurora or equivalent, site survey data from Lesson 1, sample utility bills, PDF export of production reports	Exported production report for the independent project; annual kWh output within ±10% of instructor-modeled reference, and written explanation is technically plausible. Pass = both criteria met.
5	Electrical Design, Single-Line Diagrams, and Component Selection	14	practice	Students draft a complete single-line diagram for a residential grid-tied PV system that correctly represents all conductors, overcurrent protection devices, disconnects, and grounding/bonding paths in accordance with standard electrical drawing conventions and NEC Article 690 general requirements.	Using a given system configuration (module count, inverter model, service panel rating), draw a single-line diagram by hand on provided diagram paper, labeling each conductor with wire gauge and conduit type, each OCPD with ampere rating, and each disconnect with voltage/current rating. Cross-check the diagram against an instructor-provided single-line diagram checklist derived from standard AHJ submittal requirements; revise any items flagged during self-review. Compile the equipment schedule (module model and quantity, inverter model, AC and DC disconnect ratings, conduit types and lengths) that would accompany the diagram in a permit package, formatting it as a table.	Engineering diagram paper or CAD/drawing software (instructor choice), single-line diagram template and checklist, conductor ampacity tables (NEC Chapter 9 or instructor-prepared excerpt), equipment datasheets, pencils and rulers or computer workstations	Completed single-line diagram and equipment schedule reviewed by instructor against checklist; pass requires all conductors labeled, all OCPDs sized correctly per ampacity and inverter specs, all disconnects present, and grounding/bonding path shown. Any missing safety-critical element (disconnect, OCPD, ground) is an automatic fail requiring revision before reassessment. Pass = checklist fully complete with no unresolved items.
6	Design Package Compilation and Plan-Check Readiness	11	practice	Students assemble a permit-ready residential PV design package—including site plan, single-line diagram, shade report, equipment schedule, and structural attachment notes—and present it in a structured peer review that replicates an AHJ plan-check, identifying and correcting at least 90% of seeded errors introduced by the instructor.	Compile all documents produced across previous lessons (site plan with array layout and setbacks, single-line diagram, PVWatts or software production report, module and inverter datasheets, equipment schedule) into a single organized permit package following a standard AHJ cover-sheet format provided by instructor. Exchange permit packages with another student team; use the AHJ-style plan-check checklist to review the other team's package, marking deficiencies in a written review memo—instructor has seeded at least five deliberate errors in each package for students to find. Revise own package based on peer and instructor feedback; submit the corrected final package and participate in a 10-minute oral debrief where the instructor asks two or three questions about design decisions to confirm understanding.	All documents from prior lessons, AHJ cover-sheet template (instructor-prepared based on common municipal format), plan-check checklist, three-hole binder or digital folder structure, oral debrief rubric	Final submitted permit package and oral debrief; pass requires correct identification of at least 90% of seeded plan-check errors in peer package, and own final package free of any remaining safety-critical errors after revision. Oral debrief: student must answer at least 2 of 3 questions correctly to demonstrate design rationale. Pass = both criteria met.

Instructor go/no-go LOTO checklist (8 required steps): student must complete all 8 steps in correct order and confirm zero voltage reading; any missed step or wrong sequence = immediate remediation and repeat; 100% completion required to pass.
5	Conductors, Overcurrent Protection, and NEC Sizing Principles	13	theory	Given a PV circuit's current and environmental conditions, students will select the minimum conductor ampacity and overcurrent protective device rating using NEC conductor sizing principles and PV-specific correction factors, with no undersized selections on a 6-circuit worksheet.	Lecture and guided notes: instructor presents NEC ampacity table concepts, the 125% continuous-load multiplier for PV circuits, and temperature and conduit-fill correction factors; students complete a partially filled table in their workbook for three sample circuits. Conductor sizing workshop: working in pairs, students receive six PV circuit specification cards (varying short-circuit current, conduit type, ambient temperature, and run length) and size the wire gauge and OCPD for each, citing the reasoning step by step on a worksheet. Class debrief with error analysis: instructor posts the answer key on the projector; pairs that have a different answer must walk through their reasoning aloud; class identifies which step caused any discrepancy and corrects it.

6	Reading Electrical Schematics and Wiring a PV Sub-Circuit	12	practice	Students will interpret a residential PV one-line diagram and wiring schematic, then correctly wire a three-component sub-circuit (module simulator, DC disconnect, and combiner) on a training board, verified by a continuity and polarity check.	Schematic reading exercise: instructor distributes a simplified residential PV one-line diagram; students identify and label every major component (modules, combiner box, DC disconnect, inverter, AC disconnect, utility meter, service panel), then trace the current path from module to grid in writing. Wiring practice on training board: using module simulators, a mini combiner, and a DC disconnect mounted on a training board, students follow the provided wiring diagram to make all connections with correct conductor color coding (red/positive, black or white/negative for DC as per NEC), proper torque using a torque screwdriver, and correct polarity. Verification and peer review: student applies LOTO, then uses a multimeter to perform continuity checks on each conductor run and a polarity check at the combiner output; a peer reviews the results against the wiring diagram and signs off before the instructor performs a final check.

Lecture and illustrated slide deck covering rail-based vs. rail-less rooftop systems, ground-mount driven-pier and ballasted systems, and flat-roof low-slope ballasted racks; students annotate a comparison matrix. Case-study review of three real installation photos: students identify the mounting system type, roof material, and list two site factors that drove that choice, then present findings to the group. Guided reading of two manufacturer installation manuals (one rooftop rail system, one ground-mount system); students highlight maximum allowable spans, wind/snow rating caveats, and warranty conditions.	Manufacturer installation manuals (rooftop rail and ground-mount product lines), slide deck, system comparison matrix worksheet, sample permit drawing set, whiteboard	10-question written quiz on system types and selection criteria; pass mark 80%. Instructor verifies matrix is complete before quiz.
2	Roof Assessment, Structural Evaluation, and Load Basics	12	demo	Students will conduct a roof condition inspection and locate rafter positions on a mock roof section, recording all findings on a site assessment form that meets a defined completeness standard.	Instructor-led demonstration on a mock roof section: how to use a stud finder and probe to locate rafters, measure rafter spacing, assess sheathing condition, and identify roofing material type; students shadow and then repeat the steps independently. Guided introduction to dead load, live load, wind uplift, and snow load concepts using the manufacturer's load table; students calculate required attachment spacing for a given roof pitch, wind speed, and rafter span using the table lookup method. Pairs complete a roof assessment form on the mock section, recording rafter spacing, pitch (using a pitch gauge), sheathing thickness estimate, and roofing material; instructor reviews each form for accuracy and completeness.	Mock roof section with rafters and OSB sheathing, stud finder, probe, tape measure, pitch gauge, load tables from manufacturer manual, site assessment forms, PPE (hard hat, non-slip footwear, gloves)	Completed site assessment form reviewed by instructor; all required fields populated, rafter locations within ±1 inch of actual, load table calculation verified correct. Incomplete or inaccurate forms require one re-attempt before progressing.
3	Rooftop Fall Protection and Roofwork Safety	10	practice	Students will don and inspect personal fall-arrest equipment and establish a compliant anchor and lanyard setup on a rooftop training prop, demonstrating all steps from the OSHA 1926 Subpart M sequence without prompting.	Classroom session on OSHA 1926 Subpart M fall protection requirements for residential construction, covering the 6-foot trigger height, acceptable systems (PFAS, safety nets, guardrails), and the hierarchy of controls; students complete a hazard identification worksheet for three rooftop scenarios. Hands-on inspection drill: each student inspects a full-body harness, shock-absorbing lanyard, and anchor point connector, tagging each component as pass or remove-from-service using a defect identification card with at least five planted defects in the equipment set. Supervised practice on a low-slope roof training prop: students don harnesses, connect lanyards to a certified anchor, move safely across the surface to a mock layout area, and practice tying off tools; instructor observes and scores each student against a step-by-step safety checklist.	Full-body harnesses, shock-absorbing lanyons, anchor connectors, roof anchor plates, tool lanyards, defect identification cards, OSHA 1926 Subpart M reference handout, low-slope roof training prop, hard hats, non-slip boots	Instructor-scored safety checklist (minimum 90% of steps performed correctly and in order); any missed critical step (e.g., failure to inspect harness, failure to anchor before moving) is an automatic fail requiring full repeat of the activity.
4	Flashing, Penetrations, and Attachment Hardware	15	lab	Students will install a minimum of four flashed standoff penetrations in a mock asphalt-shingle roof section using correct flashing technique so that each penetration passes a water-intrusion test and a torque verification check.	Demonstration by instructor of the shingle-weave flashing method: removing and re-laying shingles, positioning the flashed standoff mount, applying sealant, and re-integrating shingles; students watch, then perform the steps on their own mock section. Students install four standoffs on their assigned mock roof panel, varying row positions to simulate a real layout; each penetration receives a lab log entry noting bolt size, sealant brand and lot, torque value applied, and date. Water-intrusion test using a hose-and-bucket pour-over simulation: instructor and student observe the underside of the roof deck for 60 seconds; any sign of water entry requires the student to reflash and retest.	Mock roof sections (OSB on framed props) with asphalt shingles, pre-flashed standoff mounts, appropriate lag bolts, impact driver, torque wrench, roofing sealant, shingle pry bar, utility knife, lab log notebooks, hose and bucket, PPE	All four penetrations pass water-intrusion test with zero leaks; torque on each lag bolt recorded and within manufacturer specification (verified by instructor with calibrated torque wrench); lab log entries complete. Any failed penetration must be corrected and retested on the same session day.
5	Rail Layout, Module Clamping, and Grounding Continuity	16	lab	Students will mount and align a set of aluminum rails and clamp a four-module string on a rooftop mock-up within manufacturer tolerances for spacing, leveling, and rail end clearance, and will complete a continuity check on the bonding path.	Layout planning exercise using a scaled drawing of the mock roof: students calculate standoff positions, mid-clamp and end-clamp locations, rail splice positions, and verify module overhang limits comply with manufacturer spec before any hardware is installed. Team installation on the mock rooftop prop: one pair installs and levels rails using a spirit level and string line while the other pair stages modules and hardware; teams rotate roles at the midpoint; instructor circulates and coaches on torque sequence, rail squareness, and clamp seating. Continuity check using a low-resistance ohmmeter or continuity tester: students probe each mechanical bonding point in the grounding path (standoff-to-rail, rail-to-clamp, clamp-to-module frame) and record readings in the lab log; any reading outside acceptable range triggers a re-torque and retest.	Aluminum rails, mid-clamps, end-clamps, splice kits, dummy PV modules (or decommissioned modules), spirit level, string line, tape measure, cordless impact driver, torque wrench, low-resistance ohmmeter or continuity tester, lab log, manufacturer installation manual, PPE	Rail alignment within ±¼ inch of planned layout, level verified with spirit level (no visible bow), all clamps torqued to manufacturer spec, continuity readings recorded and within acceptable range. Instructor spot-checks three random clamping points with calibrated torque wrench. Pass requires all three within spec.
6	Ground-Mount Systems and Final Inspection Readiness	10	field	Students will assemble a section of driven-pier or surface-ballasted ground-mount racking in the field exercise yard, then complete a pre-inspection punch-list checklist and correct all identified deficiencies before a simulated AHJ walk-through.	Field assembly on the training yard: student teams assemble a ground-mount rack section following a provided engineered drawing, including installing piers or ballast blocks, attaching horizontal struts, leveling the structure, and mounting dummy modules using the correct clamp sequence. Peer punch-list inspection: teams swap completed rack sections and systematically walk through a 20-item pre-inspection checklist covering alignment, hardware torque, grounding continuity, module clearances, and label placements; each discrepancy is written up with a corrective action. Simulated AHJ walk-through led by the instructor acting as inspector; students stand at their corrected assembly, answer questions about attachment methods, load paths, and code compliance references, and present their completed documentation package (layout drawing, torque log, inspection checklist).	Ground-mount racking kit (driven-pier or ballasted type), dummy PV modules, torque wrench, level, tape measure, engineered drawing set, 20-item pre-inspection checklist, label stock, bonding hardware, PPE (hard hat, safety glasses, gloves, steel-toed boots)	All 20 punch-list items resolved before simulated walk-through; instructor (as AHJ) scores the documentation package and verbal responses on a 10-point rubric — pass requires 8/10.

Instructor demonstrates step-by-step datasheet matching: reading module Voc, Vmp, Isc, and Imp; applying temperature correction factors for the local climate; comparing results against inverter minimum and maximum input voltage and current limits on the board while narrating each decision. Guided practice: students work paired problems on three pre-built scenario worksheets (residential rooftop, high-temperature desert climate, partial-shade site) using a scientific calculator; instructor circulates and corrects errors in real time before students move to the next scenario. Design review exercise: students receive a flawed single-line diagram where string voltage exceeds inverter Voc max at low temperature and must write a corrected string configuration with a written justification citing module datasheet values and temperature correction math.	Scientific calculators, module and inverter datasheets (minimum three module models, two inverter models), temperature correction factor tables, scenario worksheet packets, Photovoltaic Systems by Dunlop (array sizing chapters)	Graded worksheet set; students must correctly solve all three scenarios with no uncorrected voltage or current violations and show full calculation work; 70% overall score required.
3	Inverter Installation and Electrical Safety	16	lab	Students will mount an inverter, route and terminate DC and AC wiring to manufacturer and NEC torque specifications, and apply a complete lockout/tagout sequence before any wiring work begins.	Pre-lab safety briefing and demonstration: instructor performs a complete lockout/tagout sequence on the lab inverter circuit (AC disconnect, DC disconnect, PV array simulator off), verifies zero energy with a multimeter, then restores energy; students each perform the same sequence individually and are signed off by the instructor before touching any conductor. Hands-on installation lab: working in pairs on a full-scale wall-mounted lab station (string inverter connected to a PV array simulator), students mount the inverter to blocking, route DC input conductors through conduit or cable management per manufacturer instructions, make torqued terminal connections using a calibrated torque driver, and install AC output wiring to a load-center breaker; all torque values are recorded on a provided log sheet.

5	Troubleshooting Inverter Faults	12	lab	Students will apply a systematic diagnostic process to identify and document the root cause of at least four distinct inverter fault conditions seeded by the instructor.	Fault-tree lecture and practice: instructor introduces a five-step troubleshooting methodology (observe symptoms, gather data, develop hypothesis, test hypothesis, repair and verify) and walks through two seeded faults live on the lab inverter — one DC-side (reversed polarity on a string) and one AC-side (open neutral) — narrating every meter reading and decision point. Fault station rotation: five lab stations are pre-loaded by the instructor with different faults (examples: loose DC terminal causing high resistance, blown fuse in disconnect, incorrect AC voltage setting, ground fault relay tripped, communication cable unplugged causing monitoring failure); students rotate through stations in pairs, following the five-step method, documenting measurements and conclusions on a fault-finding worksheet. Root-cause write-up: for each station, students write a two- to three-sentence root-cause statement and a recommended corrective action; the class reconvenes and reviews answers together, with the instructor revealing the seeded faults and comparing them to student findings.	Five seeded-fault inverter lab stations, multimeters, clamp meters, insulation resistance tester (Megger or equivalent), manufacturer fault code reference guides, fault-finding worksheets, safety PPE (safety glasses, insulating gloves), NABCEP PV Associate Study Guide (troubleshooting content)	Fault-finding worksheet scored by instructor; students must correctly identify root cause and corrective action for at least four of five stations (80% fault identification rate) and must follow PPE and LOTO protocols at every station — any PPE or LOTO violation results in an automatic station repeat.
6	Inverter Monitoring, Performance Analysis, and Documentation	8	theory	Students will interpret inverter monitoring data to identify underperformance conditions and produce a complete inverter documentation package meeting quality-assurance standards.

3	System Sizing: Load Analysis, Autonomy, and Battery Bank Design	12	theory	Students will size a battery storage bank for a given residential backup application by calculating total critical load energy demand, required usable capacity, required nameplate capacity based on DoD limit, and selecting a battery model and configuration (series/parallel) that meets the design criteria.	Instructor works through a full sizing example on the whiteboard: students list critical loads (kW), multiply by backup hours to get kWh demand, divide by allowable DoD to get required nameplate kWh, then select a battery model from a spec sheet and determine the number of units and series/parallel configuration; students replicate the calculation in a guided worksheet. Students complete two independent sizing problems of increasing complexity—one flooded lead-acid off-grid scenario with temperature derating and one LFP AC-coupled grid-tied backup scenario—using provided load lists, spec sheets, and a scientific calculator; peer-check answers before instructor review. Introduction to software-assisted sizing: students use a free browser-based PV and storage sizing tool (instructor selects an available free platform such as PVWatts or a manufacturer sizing tool) to model the second scenario and compare software output to their hand-calculation results, noting any differences and explaining discrepancies in a short written reflection.	Scientific calculators, printed load-analysis worksheets, manufacturer spec sheets (matching those used in Lesson 1), laptop or tablet with internet access for sizing software, NABCEP PV Installation Professional Exam Prep Guide (energy storage section), whiteboard	Both independent sizing problems graded by instructor; students must correctly calculate required nameplate capacity and select a valid battery configuration with no more than one arithmetic error per problem (75% accuracy across all numerical steps). Written reflection must identify at least one meaningful difference between hand calculation and software output.
4	Wiring Methods, Overcurrent Protection, and Code Compliance for Battery Systems	14	lab	Students will wire a DC-coupled battery subsystem on a training board—including battery terminals, fusing, disconnecting means, and BMS wiring—in compliance with manufacturer instructions and applicable NEC requirements for energy storage systems.	Pre-lab lecture and code reading: instructor guides students through the NEC articles governing energy storage systems (including Article 706 and relevant sections of Article 690); students annotate a printed code excerpt to identify required disconnecting means location, overcurrent protection sizing rules, and wiring method requirements for the battery circuit, then discuss findings as a class before touching any equipment. Hands-on lab on training boards: working in pairs, students install a battery module (training/simulator unit), connect properly sized fused disconnects on both positive and negative conductors per manufacturer specs, run appropriately sized copper conductors in conduit to the inverter-charger connection point, and land BMS communication wires to the inverter-charger's designated terminals; instructor circulates and checks work at three hold points (rough-in, conductor landing, BMS wiring). Self-inspection using a printed code-compliance checklist derived from NEC Article 706 requirements; students mark each item pass or fail on their own board, correct any deficiencies, then submit the board for instructor final inspection.

Overall checklist score must be 80% or higher for non-safety items before moving to commissioning lesson.
5	Battery Management Systems, Inverter-Charger Configuration, and System Commissioning	13	practice	Students will commission a battery storage system by configuring inverter-charger charge parameters, verifying BMS communication, checking state of charge, and confirming correct operation in backup and grid-tied modes using manufacturer commissioning procedures and a digital diagnostic interface.	Instructor-led demonstration of a complete commissioning sequence on a live training board (PV simulator, battery module, inverter-charger, and utility simulator): instructor narrates each step—visual pre-energization inspection, slow-blow fuse or pre-charge resistor use where required, BMS connection verification, inverter-charger software configuration of charge voltage set points, float voltage, and charge current limit—while students follow along with the manufacturer commissioning checklist. Students work in pairs on training boards to configure a provided inverter-charger (e.g., Victron, SMA Sunny Boy Storage, or equivalent trainer) using the manufacturer's configuration software on a laptop; they set battery type, capacity, charge algorithm, low-voltage disconnect, and grid interaction mode (self-consumption or backup priority), then document every parameter they set on a commissioning log sheet. Functional verification exercise: instructor induces three deliberate faults (disconnected BMS cable, incorrect float voltage setting, and a simulated grid outage via the utility simulator); students must use the digital diagnostic display and multimeter measurements to identify each fault, document it, and correct it within a specified time, recording findings in their commissioning log.	Training boards from Lesson 4 (wired and inspected), laptop with manufacturer configuration software installed, CAT III digital multimeters, manufacturer commissioning checklist (printed), commissioning log forms, inverter-charger quick-start guide and full manual, PPE (safety glasses, insulated gloves)	Completed commissioning log reviewed by instructor; all required parameters must be documented with values within manufacturer-specified acceptable ranges.

Students receive a scenario packet representing a completed installation (PV array, AC-coupled battery system, main service panel) with deliberate as-built changes from the permit drawings; working individually, students redline the original single-line diagram to reflect actual installed conditions, update the equipment schedule with model numbers and ratings, and prepare a placard-ready system summary sheet formatted for AHJ submittal, referencing NEC labeling requirements. Maintenance planning activity: students develop a one-year preventive-maintenance schedule for the system in the scenario packet, specifying inspection tasks (terminal torque check, state-of-health test, vent inspection for lead-acid, firmware update check for lithium-ion systems), frequency, required tools, and the safety precautions (LOTO, PPE) required for each task; schedule is peer-reviewed against a provided industry maintenance reference. NABCEP exam mapping exercise: instructor provides a printed matrix of NABCEP PV Associate and PV Installation Professional task areas related to energy storage; students annotate each task area with the specific lesson, activity, or lab in this course that addressed it, identify any gaps, and create a personal study plan for exam preparation, which they submit as the final deliverable of the course.	Scenario packet with permit single-line diagram, as-built change markup, equipment cut sheets; drafting pencils, colored pencils or highlighters for redlining; laptop or tablet with free single-line diagram drawing tool (e.g., Lucidchart free tier or AutoCAD viewer); printed NABCEP PV Associate and PV Installation Professional task-area outlines; maintenance reference (e.g., manufacturer O&M manual); NEC codebook	As-built single-line diagram evaluated against an instructor answer key: all as-built changes must be correctly captured and all required NEC labels included (pass = 80% of items correct).

Lessons · 4 blocks

#	Lesson	Hr	Type	Objective	Activities	Materials	Check
1	Site Assessment, Load Analysis, and System Design	24	lab	Given an assigned project scenario, students will conduct a roof or ground-mount site assessment, perform a shading analysis with a solar pathfinder or app-based tool, calculate system size from load data, and produce a complete NEC 690-compliant single-line diagram and bill of materials.	Teams of two visit the program's mock-site or a cooperating building, use a Solar Pathfinder or Solmetric SunEye (or equivalent app) to map shading obstructions at three potential array locations, record tilt and azimuth, and select the optimal location with a written justification citing annual production impact. Using the customer's utility bill provided by the instructor, each student calculates annual kWh consumption, determines DC system size using a standard peak-sun-hour method, selects modules and inverter from a real equipment catalog, calculates string sizing and voltage/current limits per NEC 690.7 and 690.8 principles, and records all calculations on a structured worksheet. Each student drafts a single-line diagram by hand and then reproduces it in a free CAD or design tool (such as Aurora Solar free tier, Helioscope student access, or SketchUp with a solar plugin), labels all required components and disconnects, and submits the diagram with an itemized bill of materials and a short written narrative explaining equipment choices.	Solar Pathfinder or app-based shading tool, compass, inclinometer, tape measure, utility bill sample handouts, module and inverter specification sheets from at least two manufacturers, NEC Article 690 reference copy, string-sizing worksheet template, laptop with CAD or PV design software, graph paper, ruler	Instructor reviews the single-line diagram against a rubric: all required disconnects present, string voltage within inverter and NEC limits, grounding and bonding shown, labels complete, and BOM matches diagram. Pass = 80% rubric score with zero uncorrected code violations.
2	Racking, Module Installation, and DC Wiring	36	lab	Students will install a racking system, mount and bond PV modules, route and terminate all DC conductors in conduit, and label all equipment correctly on the program's full-scale training structure, following the project's approved single-line diagram and maintaining lockout/tagout and fall-protection protocols throughout.	Working in assigned crews of three, students lay out and install a flush-mount racking system on the training roof mockup using manufacturer installation instructions: locate and mark rafters, install flashing and lag bolts at required spacing, attach rails, install mid and end clamps, torque all fasteners to spec with a calibrated torque wrench, and have each fastener point signed off by a partner acting as safety checker before the next step begins. Crews mount modules, make all module-to-module bonding connections using listed hardware, route DC home-run conductors through weatherproof conduit from the array to the combiner or inverter location, use proper fill-calculation to select conduit size, pull conductors with wire lubricant, and make terminated connections—each student must personally land at least four conductors with a torque screwdriver set to manufacturer spec. Students conduct a pre-energization checklist: verify polarity at each source circuit with a multimeter, confirm all conduit supports are within code-required spacing, check that all wire management is complete, attach NEC-required labels at the combiner and disconnect, photograph every labeled component for the documentation package, and complete the program's DC installation inspection checklist before calling for instructor sign-off.	Flush-mount racking kit (rail, feet, clamps, flashing), PV training modules (non-energized or low-voltage simulation panels), MC4 connectors and crimping tool, conduit (EMT and liquid-tight), conduit bender, conduit fittings and hangers, fish tape, THWN-2 wire in appropriate gauges, wire lubricant, torque wrench and torque screwdriver, multimeter, voltage/current clamp meter, permanent markers, NEC 690 labels kit, drill and bits, PPE (hard hat, safety glasses, gloves, fall-arrest harness), OSHA lockout/tagout kit, DC installation checklist handout	Instructor performs a live walkthrough inspection using the program's graded checklist: structural attachment, bonding continuity, polarity, conduit fill, labeling, and torque documentation. Pass = 80% checklist score with zero uncorrected safety deficiencies; any lockout/tagout violation is an automatic restart of that task.
3	Inverter Installation, AC Wiring, Commissioning, and Rapid Shutdown	30	lab	Students will mount and wire a string inverter or microinverter system to AC point-of-connection, complete commissioning steps per manufacturer startup procedure, verify rapid-shutdown operation, and record all measurements required for a commissioning report.	Each student mounts an assigned inverter on the training wall at the location shown on their single-line diagram, routes AC conductors through conduit to a utility disconnect and simulated load-center connection, sizes the OCPD per NEC 690 backfeed rules, lands all conductors at specified torque, installs the rapid-shutdown initiator device at the required location, and wires the system-status indicator visible from the point of utility interconnection per current NEC requirements. Under direct instructor supervision at a low-voltage training supply (or using the school's grid-simulation test bench), students power up the system following the manufacturer's step-by-step commissioning checklist: check AC voltage and frequency at the inverter terminals, verify MPPT tracking response, confirm anti-islanding function using the test button or instructor-controlled grid dropout simulation, and trigger and visually verify rapid-shutdown de-energization within the time frame specified by NEC 690.12. Students complete a commissioning report form covering: all measured DC open-circuit voltages per string, measured DC operating current, AC output voltage and frequency, inverter display fault-code status, rapid-shutdown test result with timestamp, and a signed declaration that the system is safe for AHJ inspection; they then photograph the completed installation from the required inspection photo angles listed on the AHJ-style checklist.	String inverter (grid-tie training unit) or microinverter kit, rapid-shutdown transmitter and module-level electronics, AC disconnect with fuse holder, simulated load-center or training panel, EMT conduit and fittings, THWN-2 conductors, torque screwdriver, multimeter, clamp meter, manufacturer startup commissioning guide, NEC 690.12 rapid-shutdown requirement reference, commissioning report form, AHJ inspection photo checklist, camera or smartphone	Instructor reviews commissioning report and witnesses or reviews video of rapid-shutdown test. Pass = all measured values within inverter spec, rapid-shutdown verified, commissioning report complete with no blank required fields, and 80% score on the graded AC wiring and installation checklist.
4	Deficiency Identification, Documentation Package, and Project Defense	18	lab	Students will identify and document all intentionally seeded code and safety violations in a staged deficiency-exercise installation, compile a complete inspection-ready permit package for their own project, and deliver a structured oral defense of their system design and installation decisions to a panel.	The instructor presents a staged installation on the training structure containing at least five deliberate deficiencies (examples: missing equipment-grounding conductor, unlabeled disconnect, oversized OCPD, improper wire type in wet location, rapid-shutdown label missing)—each student independently inspects the installation, records each deficiency on a field-correction notice form citing the applicable NEC 690 article or OSHA standard, and proposes the correct fix; findings are discussed as a group before the solutions are revealed. Each student assembles their final permit documentation package in a project binder and digital folder: cover sheet with system summary, site plan showing roof layout and array location, NEC 690-compliant single-line diagram, equipment cut sheets for all major components, string calculation worksheet, load calculation, conduit fill worksheet, interconnection agreement checklist, AHJ inspection photo set, and commissioning report—the instructor reviews for completeness using the AHJ documentation rubric before the defense date. Each student delivers a 15-minute oral defense to a two- or three-person panel (instructors and, if available, an industry professional): presents their design rationale (site selection, system sizing, equipment selection), walks through the single-line diagram explaining code compliance at each point, answers panel questions on safety decisions and at least one scenario-based what-if question (such as a shading change or a module goes offline), and closes with a self-assessment of what they would do differently.	Staged deficiency installation on training structure, field-correction notice forms, NEC Article 690 reference, project binder and divider tabs, USB drive or shared drive folder, AHJ documentation rubric, oral defense scoring rubric, timer, panel evaluation forms for guest reviewer	Deficiency exercise: student must identify at least four of five planted deficiencies with correct NEC citation—pass = 80%. Documentation package: AHJ rubric score of 80% with no missing required sheets. Oral defense: panel scores on the four-category rubric (technical accuracy, code knowledge, safety awareness, communication clarity); pass = average score of 80% across all four categories with no category below 70%.

Lessons · 4 blocks

#	Lesson	Hr	Type	Objective	Activities	Materials	Check
1	Exam Landscape, Diagnostic Assessment, and Personal Study Planning	8	theory	Given the published NABCEP task lists for both the PV Associate and PV Installation Professional credentials, the learner will locate each task-list domain in program content, complete a scored diagnostic test, and produce a written personal study plan that prioritizes domains scored below 70%.	Side-by-side comparison exercise: learners receive printed copies of the current NABCEP PV Associate Candidate Handbook and the NABCEP PV Installation Professional Candidate Handbook, highlight every domain and sub-task, and match each to the course number (1–9) where it was taught, recording gaps. Timed 50-item diagnostic multiple-choice exam drawn equally from all credential domains; learners self-score using an answer key, calculate a percentage per domain, and enter results into a provided domain-tracking spreadsheet. Guided study-plan workshop: each learner writes a one-page SMART study plan listing the three lowest-scoring domains, specific resources (textbook chapters, NEC sections, lab notes) to review, and a daily study schedule for the remaining weeks of the course; instructor reviews and signs off.	NABCEP PV Associate Candidate Handbook (current edition), NABCEP PV Installation Professional Candidate Handbook (current edition), diagnostic exam packet (instructor-prepared), domain-tracking spreadsheet template, Photovoltaic Systems textbook (Dunlop or equivalent NJATC/ATP edition), NEC Article 690 codebook or tab-marked NEC, learner lab notebooks from prior courses.	Learner submits a completed domain-tracking spreadsheet with all domains mapped and a signed one-page study plan; instructor verifies every domain is addressed and the plan is realistic. Pass standard: all domains mapped, three priority domains identified with specific resources cited, study schedule covers remaining course days.
2	Domain Deep-Dive: System Design, Sizing, Electrical Theory, and NEC 690 Code Review	16	theory	The learner will accurately solve PV system sizing calculations (array voltage, current, conductor ampacity, overcurrent protection, string configuration) and correctly apply NEC Article 690 rules and electrical theory concepts in timed practice-question sets, scoring at least 75% on each domain sub-quiz.	Instructor-led worked-example sessions covering the highest-frequency calculation types on NABCEP exams: Voc temperature correction, Vmp temperature correction, array series/parallel string sizing, minimum conductor ampacity (125% continuous load rule), DC and AC disconnect sizing, and conduit fill; learners work each problem independently then compare with the instructor's solution, noting formula sources in their notes. NEC 690 speed-drill: learners receive a 30-item fill-in-the-blank worksheet requiring them to cite the correct code provision (e.g., rapid shutdown requirements, ground-fault protection, labeling) using only a tabbed NEC; they complete it in 25 minutes, then review errors in pairs, and re-attempt any missed items. Domain sub-quizzes: three separate 20-item timed quizzes covering (a) system design and sizing, (b) electrical theory fundamentals, and (c) NEC 690 code compliance; learners record scores in their domain-tracking spreadsheet and flag any item type missed more than once for targeted self-study that evening.	NEC (current adopted edition) with Article 690 tabbed, Photovoltaic Systems textbook, manufacturer specification sheets (sample module and inverter datasheets from prior courses), scientific calculator, domain sub-quiz packets (instructor-prepared), formula reference sheet (instructor-prepared, identical in format to any allowed reference on the actual exam), learner domain-tracking spreadsheets.	Score on each of the three 20-item domain sub-quizzes recorded and reviewed; pass standard is 75% (15/20) on each. Learners scoring below 75% on any sub-quiz must complete a targeted 10-item remediation set on that domain before the next lesson and achieve 80% on the remediation set.
3	Domain Deep-Dive: Safety, Site Assessment, Mounting, Inverters, Battery Storage, and Installation Practices	12	demo	The learner will correctly answer practice questions covering OSHA fall-protection and lockout/tagout requirements, roof and ground-mount structural considerations, inverter and battery storage selection and commissioning, and hands-on installation quality standards at a rate of at least 75% on timed domain quizzes.	Case-study carousel: four stations (safety/OSHA, mounting/structural, inverters, battery storage) each with a one-page scenario and five scenario-based multiple-choice questions modeled on the NABCEP item style; learners rotate every 15 minutes, complete all four stations, then debrief as a class with the instructor explaining the reasoning behind each correct answer and common wrong-answer traps. Instructor demonstration of equipment identification speed drill: instructor displays images of PV system components (AC/DC disconnect, combiner box, microinverter, string inverter, rapid-shutdown device, battery management system, conduit fittings) on a projector; learners write the component name and one code or safety requirement associated with it within 30 seconds per image, then self-score against the answer key. Peer-teaching pairs: each learner selects the domain they scored lowest on in Lesson 1 diagnostic or Lesson 2 sub-quizzes, prepares a five-minute verbal explanation of the key concept or code rule as if teaching a co-worker, delivers it to a partner who then asks two follow-up questions; instructor observes and provides feedback on accuracy.	Projector and component-image slide deck, OSHA 1926 Subpart R (steel erection) and Subpart M (fall protection) quick-reference cards, lockout/tagout procedure template from Course 1, manufacturer installation manuals (sample inverter and battery from prior courses), NEC Article 690, domain quiz packets (instructor-prepared), learner domain-tracking spreadsheets.	Four-station carousel scored out of 20 items; pass standard is 75% (15/20) overall. Peer-teaching observed by instructor using a three-point rubric (accurate content, clear explanation, correctly answered follow-up questions); learners must score 2/3 or higher. Learners below threshold on either activity complete an additional targeted practice set before the mock exam.
4	Full-Length Timed Mock Certification Exams and Final Debrief	9	practice	Under timed, closed-book exam conditions that replicate the actual NABCEP testing environment, the learner will complete a full-length NABCEP PV Associate mock exam and a full-length NABCEP PV Installation Professional practice exam, then analyze individual results by domain and articulate a final pre-exam action plan.	Mock Exam Session A — NABCEP PV Associate: learners complete a full-length practice exam (number of items consistent with the published exam blueprint) under strict timed conditions with no notes; upon completion, learners self-score by domain using the provided answer key and record results in the domain-tracking spreadsheet. Mock Exam Session B — NABCEP PV Installation Professional: following a short break, learners complete a full-length NABCEP PV Installation Professional practice exam under the same timed, closed-book conditions; self-score and record domain results in the tracking spreadsheet. Individual debrief conference: each learner meets one-on-one with the instructor for 10 minutes, reviews their cumulative domain-tracking data across all four lessons, and receives written instructor feedback identifying readiness level; learner then writes a final one-page action plan listing any domains still below 75% and specific self-study activities (textbook sections, practice problems, NEC article review) to complete before the official exam date.	Mock exam packets — PV Associate and PV Installation Professional (instructor-prepared, aligned to current NABCEP exam blueprints), answer keys with domain codes, scientific calculators, NEC (for NABCEP PV Installation Professional mock, consistent with whatever reference policy the actual exam allows — instructor clarifies current NABCEP policy from the candidate handbook), pencils, domain-tracking spreadsheets, final action-plan template.	Readiness threshold: score of 75% or higher overall on each mock exam is considered exam-ready. Learners scoring 70–74% are advised to schedule additional self-study; learners scoring below 70% receive a mandatory supplemental study session with the instructor and are counseled on whether to defer the official exam. Completion of the written final action plan is required for course completion regardless of score.
