A PVI1 is the Photovoltaic Installer - Level 1 certification from ETA International. It signals that a person understands the fundamentals of installing solar photovoltaic (PV) systems and has demonstrated hands-on skills in the area. If you have seen the abbreviation on a job posting, a school catalog or a training provider's website, this is the credential that matters on this page. It is an entry-level, installer-focused credential, not a design-engineer license and not a general electrician qualification.
This article explains what the credential covers, how it is structured, what it costs to sit the exam, and how it fits into a solar career. For deeper dives, you can follow the links throughout to our guides on PVI1 requirements, PVI1 certification cost and the eight exam domains.
Who Issues the Credential and Who Tests You
The governing body is ETA International (Electronics Technicians Association, International). ETA publishes the competency requirements, sets the exam rules and issues the certificate. Candidates are tested through ETA Certification Administrators, and ETA's general administration system offers both Trapeza online testing and paper-and-pencil delivery. Hands-on training and skill demonstrations run through an ETA-approved trainer or school.
Notably, there is no Pearson VUE, PSI or Prometric testing path for this credential. If a site tells you to book your PVI1 through one of those vendors, treat that as a red flag and verify directly with ETA.
The Two-Part Structure: Hands-On Skills Plus a Knowledge Exam
PVI1 is not a pure multiple-choice test you can cram for in isolation. It has two components:
- Hands-on skill demonstrations. ETA's current issuer page calls for hands-on training from an ETA-approved trainer or school. According to ETA's competency document, practical skills are demonstrated before you sit the knowledge examination.
- A 75-question knowledge examination. This is the written test most people think of when they say "the PVI1 exam." The practical demonstrations are not counted in the 75 questions.
ETA's competency PDF also allows the organization to review proof from prior job experience in lieu of trainer-taught skills. That is a discretionary review, not an automatic waiver, so do not assume your work history substitutes for the hands-on component without checking with ETA first. Our PVI1 requirements guide walks through how eligibility questions like this typically play out.
No universal training-hour minimum
You will see training courses advertised at 40, 45, 46 or 60 hours. Those figures describe specific providers' courses. They are not a universal ETA requirement for PVI1, and no minimum degree, age or experience-hour threshold was verified from current issuer material. PVI1 is also a Stand-Alone certification, so the CETa credential is not required under ETA's general rule.
The Eight Competency Areas You Are Tested On
ETA's Photovoltaic Installer - Level 1 (PVI1) Competency Requirements document (copyright 2022, eight pages) lists eight numbered categories, and ETA states that certification examination questions are derived from the corresponding competencies. The categories are unweighted. ETA does not publish percentages or identify a "largest" domain, so be skeptical of any source claiming exact weightings.
Domain 1: History and Background of Renewable Energy
Context for the industry: where PV fits among renewable sources and how the technology developed.
- Understand PV's place within the broader renewable energy picture
- Be able to place major developments in solar technology in context
Domain 2: Photovoltaics Terminology
The shared vocabulary of the trade. Misreading a term can derail a calculation or a safety decision.
- Know the names of system components and their roles
- Distinguish electrical terms that sound similar but mean different things
Domain 3: Installation and Safety
The practical heart of an installer credential: working safely and installing equipment correctly.
- Recognize electrical, fall and handling hazards on a solar job
- Connect installation steps to the hands-on skill demonstrations
Domain 4: Codes and Standards
The rules that govern how systems are installed and inspected.
- Be familiar with the code references named in ETA's competency document
- Note that the PDF mixes older code references, including NEC 2017, so a single current NEC edition for the exam is not established
Domain 5: Theory of Operation
How a PV system actually converts sunlight into usable electricity and what affects its output.
- Explain the basic function of a PV system's major parts
- Understand why conditions like shading and temperature change performance
Domain 6: Applied Calculations and Formulas
Where candidates most often need deliberate practice, because it requires working through numbers rather than recalling facts.
- Practice basic electrical relationships and their application to PV arrays
- Bring a permitted calculator and know its rules (see the exam-day section below)
Domain 7: Estimating Home Energy Needs
Connecting a household's consumption to the size of a system.
- Work from usage to a reasonable system-sizing starting point
Domain 8: Project Management
The organizational side of a job: planning, sequencing and documentation. Some third-party comparison tables claim Level 1 has no project management content, but ETA's own competency PDF lists it as category 8.
- Understand how an installation project is planned and tracked
The competency PDF also opens with an introductory hands-on task list. That is part of the hands-on skills framework, not a ninth numbered domain. For a fuller breakdown of every area, read our complete guide to all 8 PVI1 content areas.
Exam Numbers: Questions, Time, Fee and Passing Score
| Item | PVI1 Detail |
|---|---|
| Issuer | ETA International |
| Knowledge exam length | 75 questions |
| Time limit | Two hours |
| Passing score | 75% on the knowledge exam; hands-on competency also required |
| Exam fee | $155 (no member/non-member split published) |
| Retake policy | One free retake within one year of the first exam session |
| Credential term | Four years, with maintenance required |
A few clarifications keep expectations realistic:
- Scored vs. unscored items: ETA does not disclose a split, so do not assume all 75 count or that some are experimental.
- Question format: A current issuer statement specifying multiple-choice format, case-study mix or adaptive delivery was not found. A historical Florida Department of Education record describes 75 multiple-choice questions, but that is a dated record, not a current item specification. Likewise, marketplace practice questions do not prove the official format.
- Numerical practical cut score: No separate numerical score for the hands-on portion was verified. Hands-on competency is simply required.
- Pass rate: No reliable current cohort pass-rate series was located, which is why we discuss difficulty qualitatively in our difficulty guide and on the pass rate page instead of quoting numbers.
Exam-day rules to know
- Bring photo identification.
- A non-programmable or scientific calculator is permitted; programmable calculators may need to be reset.
- Phones and other electronic devices are prohibited.
- Scratch paper may be used and surrendered afterward.
- Open-book permission and a PVI1-specific formula sheet are not verified, so do not plan around either.
Remote testing: confirm before you count on it
ETA's test-sites page describes ExamRoom.AI remote proctoring for non-hands-on certifications, and its FAQ discusses remote candidates still attending an approved school for hands-on credentials. PVI1 has a hands-on component, so confirm exact eligibility for the knowledge test with ETA rather than assuming the whole credential can be earned remotely. For scheduling mechanics, see our notes on PVI1 exam dates and scheduling.
What PVI1 Is Not: PV2, NABCEP and Other "PVI1" Labels
Because the solar certification landscape is crowded, it helps to draw clear lines.
- Not ETA's PV2. The Photovoltaic Installer/Designer (PV2) credential is a separate ETA certification with its own requirements. Prerequisites tied to PV2, such as CSS, OSHA 10 and 60 verified training hours, do not apply to PVI1.
- Not NABCEP. NABCEP is a different organization. Its PV Associate program is an entry-level credential of its own, and it is distinct from NABCEP's PV Installation Professional certification. Comparing PVI1 with PV Associate is reasonable because both sit at the entry level, but their issuers, eligibility rules and exam content are separate. Do not borrow one's rules to describe the other.
- Not any other credential sharing the abbreviation. If a study guide mentions a different certifying body, fee or domain list, it is describing something else.
Who Pursues PVI1 and What the Job Market Looks Like
PVI1 suits people entering or moving within residential and small-scale solar installation: career changers, students in a community-college solar program, apprentices, and helpers who want a recognized credential to document their knowledge. Employers in the solar installation trade, including installation contractors and solar companies, may value third-party proof of foundational knowledge and safety awareness, though hiring preferences vary by employer and region.
On pay, the best available government benchmark is occupation-wide. The U.S. Bureau of Labor Statistics reports a May 2025 median of $53,140 per year ($25.55 per hour) for solar photovoltaic installers. That figure covers the whole occupation. It is not a PVI1-specific salary, a starting wage, or a measured certification premium, and we do not claim the credential produces a particular raise. If you want to weigh the investment, our salary guide and ROI analysis go through the evidence and its limits, and our overview of PVI1 jobs covers where the credential may help.
The Path From Training to Certificate
A typical route looks like this. Details vary by school and trainer, so confirm each step.
- Review the competency document. Download ETA's PVI1 competency requirements and read all eight categories so you know the scope.
- Complete hands-on training. Enroll with an ETA-approved trainer or school and demonstrate the required practical skills, or ask ETA about reviewing prior job experience.
- Study the knowledge content. Self-study courses can help, but partner and self-study courses explicitly do not replace certification requirements.
- Register and sit the exam. Pay the $155 exam fee and test through an ETA Certification Administrator.
- Use the retake if needed. One free retake is available within one year of the first exam session.
Vocabulary and context (Domains 1, 2)
- Build terminology fluency first, since every later domain depends on it
Safety, codes and operation (Domains 3, 4, 5)
- Pair with your hands-on training so the concepts attach to real tasks
Numbers and planning (Domains 6, 7, 8)
- Spend extra repetition on calculations; then practice sizing and project scenarios
For a full preparation plan, see our PVI1 study guide, and keep our one-page cheat sheet handy for last-minute review. You can also test yourself with original, competency-aligned questions on the main practice test site. These are practice items written for study, not actual issuer exam questions or an official mock exam.
Keeping the Credential Current
The certification has a four-year term, and maintenance is required. On ETA's Maintenance with Hands-On track, you need:
- Six continuing-education hours per year (24 over four years)
- A supervisor-signed Employer Verification Form
- A Certification Maintenance Form
- $25 per year ($100 over the four-year cycle)
ETA offers a different alternative for non-hands-on certifications, but that option does not apply to this hands-on track, so do not mix the two up when planning.
Key Takeaway
Treat PVI1 as a skills-plus-knowledge credential, not just a test. Line up an ETA-approved trainer early, because the hands-on demonstration comes before the knowledge exam, and budget for exam, training and the $25 annual maintenance fee together.
Frequently Asked Questions
PVI1 stands for Photovoltaic Installer - Level 1, a certification offered by ETA International. For more on the abbreviation, see our explainer on what PVI1 stands for.
The knowledge examination has 75 questions and a two-hour time limit. The separate hands-on skill demonstrations are not part of that question count, and a separate hands-on assessment time is not published.
You need 75% on the knowledge examination, and hands-on competency is also required. No separate numerical cut score for the practical portion was verified. Our passing score guide covers this in more detail.
The current issuer examination fee is $155, with one free retake within one year of the first exam session. Training and study materials are separate unless a provider bundles them, so total cost depends on the course you choose.
No. They come from different organizations with different eligibility rules and exam content. PVI1 is ETA International's installer-level certification; NABCEP's PV Associate is a separate entry-level program.
In short, a PVI1 is a four-year, entry-level solar installer credential from ETA International that pairs demonstrated hands-on skills with a 75-question, two-hour knowledge exam across eight competency areas. If you are weighing it against your goals, start with the eight domains, confirm the hands-on route with an approved trainer, and use the practice test site to check your readiness before exam day.
