What You Are Actually Studying For
PV Technical Sales Certification (PVTS) is issued by the North American Board of Certified Energy Practitioners (NABCEP). It is aimed at people who sell solar electric systems and need to demonstrate that their technical judgment backs up their sales conversations: evaluating a prospect, assessing a site, sketching a workable design, estimating performance, modeling the economics, and presenting a proposal that holds up under scrutiny.
That framing matters for how you study. The exam is a written, English-language multiple-choice test. It is not a live sales presentation or a practical performance assessment, so nobody grades your charisma. What gets graded is whether you can reason through the same decisions a technically competent solar salesperson makes every week. If you want background on the credential itself before going deeper, see What Is PVTS Certification? and the broader PVTS Certification overview.
This guide builds a plan around the exam's six official weighted content domains, because those weights are the only authoritative signal about where questions come from. The domain list comes from the issuer's PV Technical Sales Job Task Analysis (August 2018, V.08.18). Treat the domains as examination objectives, not as a training syllabus: they tell you what can be tested, not how any particular course happens to organize its chapters.
Eligibility Comes Before Studying
Many candidates begin with flashcards and discover months later that their application documentation is the real bottleneck. The PVTS application requires evidence that takes time to gather, and your exam eligibility window only starts once the application is approved. Sort this out first. The full breakdown lives in PVTS Requirements 2026: Eligibility, Prerequisites & How to Qualify, but the essentials are below.
Baseline prerequisites
- Age 18 or older and agreement to the ethics requirement.
- OSHA 10 Construction (or a government equivalent).
- 58 advanced PV training hours completed within five calendar years, including at least 40 advanced PVTS-JTA hours from an accepted accredited or recognized provider. Up to 18 hours can come from permitted additional sources.
Sales Credits: two qualification paths
Your sales experience is measured in Sales Credits under the 2025 handbook rules, not the older Project Credit wording that still circulates in archived announcements.
| Path | Sales Credits Required | Additional Requirement |
|---|---|---|
| Category A | 8 | None beyond the baseline prerequisites |
| Category B | 4 | An accredited science/engineering bachelor's or master's degree, a solar/renewable-energy associate degree, a current master/journeyman electrician license, or a current government-issued solar contractor license |
Under the 2025 handbook, a sold project earns 2 Sales Credits for 1-24 kW, 3 for 25-999 kW, and 4 for 1 MW or more. All qualifying projects must have been sold within the preceding two years, and at least half must be both sold and installed. At most one relative or same-address project may count, and it must be sold and installed.
Format, Fees, and Test-Day Rules
Knowing the mechanics removes avoidable stress. The exam is delivered through Meazure Learning, either by computer-based testing at a test center or by live remote proctoring. According to the 2025 handbook delivery table, both options are allowed for initial PVTS exams and retakes.
- Length: 70 multiple-choice questions, four answer options each, in 4 hours.
- Scoring: 60 questions count; 10 are unidentified pilot items that do not. You cannot tell which are which, so treat every question as live.
- Closed book: An on-screen basic scientific calculator is provided. Personal calculators, notes, and study books are not permitted.
- Code books: PVTS does not appear on the issuer's current FAQ and handbook lists that grant NEC reference access. Do not assume a codebook will be available, and do not borrow reference rules that apply to other NABCEP credentials.
- Accommodations: Approved accommodations are available through the issuer.
What it costs
The base cost is a $125 application fee plus a $375 examination fee, $500 USD total before any training. A retake is $275 and recertification is $390. The testing vendor adds $75 for candidates outside the United States and Canada. A fuller pricing walkthrough is in PVTS Certification Cost 2026: Complete Pricing Breakdown.
Timing windows
Your exam eligibility lasts one year from application approval. The scheduling instructions also mention a six-month deadline, but the published wording is inconsistent about whether that clock starts at application approval or at your Notice to Schedule. The safe rule is to follow the date printed on your own candidate notice and schedule early. More detail is in PVTS Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Key Takeaway
Four hours for 70 questions is generous pacing, roughly three and a half minutes per item. Spend the surplus on calculation questions and scenario stems rather than rushing, and reserve a final pass for flagged items.
Where the Points Live: The Six Domains
The domain table below reproduces the published weights exactly. They total 100.10% because of rounding in the issuer's outline; the issuer itself attributes non-100 totals to rounding, so do not try to "fix" them.
| Domain | Weight | Study Priority |
|---|---|---|
| 1. Qualifying Prospects | 30.00% | Highest; start here |
| 2. Site Analysis | 21.70% | Very high; calculation-heavy |
| 3. Conceptual Design | 16.70% | High; connects to Domains 2 and 4 |
| 4. Performance Analysis | 6.70% | Small but feeds Domain 5 |
| 5. Costs, Incentives, Savings, and Returns | 16.70% | High; math and reasoning |
| 6. Proposal Preparation and Presentation | 8.30% | Moderate; synthesis of everything |

Domain-by-Domain Mastery Notes
Domain 1: Qualifying Prospects (30.00%)
The single largest domain rewards candidates who can tell a good solar prospect from a poor one before investing design effort. Expect scenario questions in which a customer's circumstances, roof, utility situation, or goals determine whether to proceed, redirect, or decline.
- Practice reading a customer profile and identifying the facts that actually matter to feasibility.
- Be able to explain solar basics accurately and without overpromising to a lay customer.
- Know how electricity use, rate structure, and goals shape whether a system makes sense.
- Because this domain carries nearly a third of the exam, do not treat it as the "easy sales stuff." It is the biggest scoring opportunity and the easiest place to lose points through careless reading.
Domain 2: Site Analysis (21.70%)
This domain tests whether you can evaluate a physical site for a PV system, including roof or ground conditions, orientation, tilt, and shading effects on production potential.
- Be fluent with orientation, tilt, and shading concepts and how each changes expected output.
- Practice interpreting site information and deciding what limits the viable array area.
- Rehearse quick estimation with the on-screen calculator, since you will not have your own.
Domain 3: Conceptual Design (16.70%)
You are not expected to produce stamped engineering drawings. You are expected to understand how major components and system types fit together well enough to propose something feasible and consistent with the site and customer goals.
- Understand how modules, inverters, and balance-of-system choices interact at a high level.
- Be able to match a system type to a customer scenario and justify the choice.
- Know how design decisions constrain performance and cost, which sets up Domains 4 and 5.
Domain 4: Performance Analysis (6.70%)
The smallest domain, but it is a dependency: performance estimates drive the savings and returns calculations in Domain 5. Learn what factors derate a system's output and how production estimates are formed and sanity-checked.
- Understand the major loss mechanisms that separate nameplate capacity from delivered energy.
- Be able to judge whether a production estimate looks reasonable for a given site and design.
Domain 5: Costs, Incentives, Savings, and Returns (16.70%)
Here you convert a design into an economic story: system cost, available incentives, bill savings, and financial return metrics. Practice working through the arithmetic by hand.
- Rehearse cost and savings calculations until they are routine.
- Understand how common financial metrics are calculated and compared.
- Learn how incentives are structured in principle. The 2018 outline covers financial-incentive analysis, but it does not establish that any historic incentive remains available in 2026, so rely on the analytical method rather than memorized program details.
Domain 6: Proposal Preparation and Presentation (8.30%)
This domain tests whether you know what a credible, accurate proposal contains and how to present it responsibly. Because the exam is written, expect questions about content, accuracy, and appropriate claims rather than live delivery skills.
- Know the elements a complete proposal should include.
- Recognize misleading or unsupported claims and understand why they create risk.

Reading the Score Honestly
The passing score is 75 on a scaled range of 0 to 99. Scaled scoring is not the same as percent correct, so you cannot reverse-engineer a precise number of questions you can miss. Candidates sometimes translate "75" into "I need 75 percent" and then misjudge their readiness. Exam forms can differ in difficulty, which is exactly what scaling is designed to account for. Details are in PVTS Passing Score 2026: Exactly What You Need to Pass.
A Domain-Ordered Study Sequence
Rather than a generic weekly template, sequence your study by weight and dependency. The logic is simple: spend the most time where the exam spends the most points, and learn prerequisites before the topics that depend on them. Adjust the length to your own schedule and prior experience.
Qualifying Prospects
- Work scenario questions on prospect evaluation and customer needs.
- Review customer energy use, rate structures, and feasibility screening.
- Take notes in your own words on what disqualifies or redirects a prospect.
Site Analysis, then Conceptual Design
- Drill orientation, tilt, and shading effects with the on-screen calculator only.
- Move into component selection and system configuration logic.
- Link each design choice back to what the site allows.
Performance Analysis into Costs, Incentives, Savings, and Returns
- Study loss factors, then immediately use the estimates in savings and return calculations.
- Practice incentive analysis as a method, not as a memorized program list.
Proposal Preparation and Presentation, plus full review
- Cover proposal content and responsible claims.
- Take timed mixed-domain sets and revisit your weakest domain.
- Do one last pass on closed-book calculation habits.
Practicing under exam conditions helps: closed book, a basic scientific calculator, and four-option questions with plausible distractors. You can build that habit with the PVTS practice tests, and then check your weakest domains against the exam weights above.
Source Traps That Cost Candidates Time
Because several NABCEP credentials and several unrelated certifications circulate with similar names and acronyms, candidates routinely study the wrong material. Guard against these specific traps.
- Wrong credential content. The PVTS exam is not the same as other solar credentials, and other credentials' reference rules, code permissions, and exam outlines do not apply to it. Verify any study resource names PV Technical Sales Certification specifically.
- Outdated outlines. Older job task analyses from earlier years are superseded. The current PVTS outline is the August 2018 JTA (V.08.18). Use the issuer's linked outline rather than an old PDF from a forum.
- Old credit wording. Archived announcements use Project Credit language and different size bands. Use the 2025 Sales Credit rules in the Certification Handbook.
- Third-party chapter structures. A course's table of contents is not the exam blueprint. Measure any course against the six weighted domains.
- Assuming code access. Do not plan on referencing the NEC during the exam.
When choosing preparation resources, see PVTS Training for how training hours tie into your application, and remember that the required advanced training must come from an accepted provider to count.
After You Pass: Renewal and Careers
The certification is valid for three years. You apply for renewal during year three, and the fee is $390. Renewal requires 30 continuing education hours: 18 PVTS JTA hours plus 12 renewable energy hours, including 2 building or fire-code hours within the 12.
You must also document continued industry involvement on signed company letterhead, through any one of the following: a decision-making role in proposals for at least three completed installations during the cycle, 120 qualifying teaching hours, one year of qualifying business or training leadership, or 36 hours of qualifying industry leadership. Use the handbook's section 9.7.2 proposal wording for the proposal option. The generic renewal page's installation wording and the older involvement document tied to other credentials are not substitutes.
On the career side, the credential is relevant to people in solar sales roles at installers, developers, and similar companies. For what the certification can and cannot be said to do for pay and hiring, read PVTS Jobs, PVTS Salary Guide 2026: Complete Earnings Analysis, and Is the PVTS Certification Worth It? Complete ROI Analysis 2026. The issuer sources reviewed here do not establish a certification-only salary premium, so be skeptical of any specific figure presented as a guaranteed outcome.

Frequently Asked Questions
The exam has 70 multiple-choice questions with four answer options each. Sixty are scored and 10 are unidentified pilot items that do not count. You cannot tell which are which, so answer every question carefully. You have 4 hours.
No. The exam is closed book. An on-screen basic scientific calculator is provided, but personal calculators, notes, and study books are not permitted. PVTS is also not on the issuer's lists granting NEC reference access, so do not plan on using a code book.
Start with Qualifying Prospects, the largest at 30.00%, then move to Site Analysis at 21.70%. Together they make up more than half of the published weighting. Study Performance Analysis before Costs, Incentives, Savings, and Returns because the economics depend on the production estimates.
No. The passing score is 75 on a scaled range of 0 to 99, which is not a percent-correct figure. Scaling accounts for differences between exam forms, so you cannot convert 75 into an exact number of allowable misses.
Eligibility lasts one year from application approval. Scheduling instructions also reference a six-month deadline but anchor it inconsistently, so follow the dates on your own candidate notice and schedule early. Retakes cost $275 and may be taken by computer-based testing or live remote proctoring.
Combine the domain weights, the closed-book calculation habit, and a clean application file, and you have the three levers that matter most. Build your study sequence around the six domains, confirm your eligibility paperwork early, and test yourself under realistic conditions on the PVTS Exam Prep practice tests before exam day.
