PVI1 Certification

TL;DR
  • PVI1 means Photovoltaic Installer - Level 1, issued by ETA International, not any other credential sharing the acronym.
  • The knowledge exam has 75 questions, a two-hour limit, and a 75% passing score, plus a hands-on competency requirement.
  • The current exam fee is $155, with one free retake within one year of your first exam session.
  • ETA publishes eight unweighted competency categories, so study all of them rather than chasing a guessed blueprint.

What the PVI1 Credential Actually Is

PVI1 stands for Photovoltaic Installer - Level 1. It is an entry-level solar installation credential offered through ETA International (Electronics Technicians Association, International). If you have seen the abbreviation elsewhere, set that aside: this article covers only the ETA credential, and every fact below applies to it alone. For the naming basics, see our explainers on what PVI1 certification is and what PVI1 stands for.

PVI1 is also distinct from ETA's separate Photovoltaic Installer/Designer credential (PV2). That one carries its own prerequisites, and you should not assume PV2 requirements apply to PVI1. PVI1 is designated Stand-Alone under ETA's general rule, which means the CETa credential is not required first.

The credential pairs two things: a written knowledge examination and demonstrated hands-on skills. That combination is what separates it from a purely online quiz-based certificate, and it shapes how you should prepare.

Who Issues It and Who Administers It

ETA International governs the credential and publishes the competency requirements the exam draws from. Testing runs through ETA Certification Administrators. ETA's general administration system offers online testing through Trapeza as well as paper-and-pencil delivery. I did not find evidence that PVI1 is delivered through Pearson VUE, PSI, or Prometric, so don't search those vendors' catalogs for it.

The hands-on training and skill demonstrations go through an ETA-approved trainer or school. That is a different channel from the exam administrator, and understanding the split early saves scheduling headaches. If you want the full eligibility picture, our PVI1 requirements guide goes deeper.

The Exam at a Glance

ItemWhat ETA Publishes
Knowledge exam length75 questions
Time limitTwo hours
Passing score75% on the knowledge exam
Hands-on componentRequired; no separate numerical practical cut score verified
Exam fee$155
RetakeOne free retake within one year of the first exam session
Credential termFour years, with maintenance
Scored/unscored splitNot disclosed
Pass rateNo reliable current figure located

Two things the issuer does not tell us are worth stating plainly. First, there is no published scored/unscored split among the 75 questions. Second, I could not find a current issuer statement specifying the question style in detail, such as multiple-choice versus other formats, case-study mix, or adaptive delivery. An older Florida Department of Education record describes 75 multiple-choice questions, but that is historical, so treat it as a hint rather than a guarantee. For a deeper look at the numbers, read our PVI1 passing score guide and pass rate analysis, which explains why no trustworthy percentage exists.

Why 75% matters for pacing: With two hours for 75 questions, you have roughly 96 seconds per question on average. That is comfortable for recall items but tight for calculation items, so practice worked math under a clock rather than just reading formulas.

The Hands-On Requirement

This is the part candidates most often underestimate. ETA's current page calls for hands-on training from an ETA-approved trainer or school. The competency document indicates that practical skills are demonstrated before you sit the knowledge examination.

The same document allows ETA to review proof of prior job experience in lieu of trainer-taught skills. Note the wording: this is discretionary review by the issuer, not an automatic experience waiver. Don't plan around it as a guaranteed shortcut. An older Florida record describes a 12-month on-the-job route, but that has not been established as a current universal rule.

What is not established: any universal minimum number of training hours, degree, age, or reference count. You will see partner courses advertised at 40, 45, 46, or 60 hours, but those are individual providers' course lengths, not issuer-wide PVI1 requirements. And self-study courses explicitly do not replace the certification requirements. Our PVI1 training overview covers how to choose a provider.

Key Takeaway

Book your hands-on skills demonstration with an ETA-approved trainer or school first, then schedule the knowledge exam. Confirm the exact sequence with your school, since the competency document places skill demonstration before the written test.

The Eight Competency Areas

ETA's Photovoltaic Installer - Level 1 (PVI1) Competency Requirements document (copyright 2022, eight pages) lists eight numbered competency categories. ETA states that exam questions derive from these competencies. Critically, no weighting or percentage is published, so any article claiming "Domain 3 is 30% of the exam" is inventing a number. Treat all eight as fair game. Our complete domains guide expands on each one.

Domain 1: History and Background of Renewable Energy

Expect context questions that frame solar within the broader renewable landscape.

  • Where photovoltaics fits among renewable technologies
  • Basic historical milestones in solar development
  • Why this domain is easy points if you simply read the competency list

Domain 2: Photovoltaics Terminology

Vocabulary is the foundation for every other domain. Misreading a term can cost you a calculation question too.

  • Cell, module, panel, string, and array distinctions
  • Electrical terms you will reuse in later domains
  • Learn terms as pairs with their units

Domain 3: Installation and Safety

This domain bridges the written exam and your hands-on skills demonstration.

  • Safe work practices on rooftops and around live electrical sources
  • Mounting, wiring, and equipment installation fundamentals
  • Practice describing steps in order, since the hands-on side rewards sequence knowledge

Domain 4: Codes and Standards

Be careful here. ETA's competency PDF mixes older code references, including NEC 2017 and a 2020 NEC study resource, and no single current exam code edition was verified.

  • Know the code topics each competency names
  • Ask your trainer which NEC edition their course uses
  • Do not assume your local adopted code matches what the exam references

Domain 5: Theory of Operation

How a PV system converts sunlight to usable electricity, and how the pieces interact.

  • Cell-to-system energy conversion concepts
  • Component roles in a working system
  • Understanding the "why" makes troubleshooting-style questions easier

Domain 6: Applied Calculations and Formulas

The domain most candidates fear, and the one that rewards deliberate practice.

  • Series and parallel electrical relationships
  • Power, voltage, current, and energy calculations
  • Unit handling and rounding discipline

Domain 7: Estimating Home Energy Needs

A practical, customer-facing skill: translating a household's consumption into system requirements.

  • Reading usage information and converting it into sizing inputs
  • Connecting load estimates to the calculation methods from Domain 6

Domain 8: Project Management

Don't skip this one. A third-party comparison table claims Level 1 has no project management content, but ETA's own linked competency PDF lists it as category 8.

  • Planning, scheduling, and coordinating an installation job
  • Documentation and communication with customers and inspectors

One more detail: the competency document includes an introductory hands-on Job Task Analysis. It is not a ninth numbered domain, but it previews the practical skills you will demonstrate. For a difficulty perspective on these areas, see how hard the PVI1 exam really is.

What PVI1 Certification Really Costs

The cleanest number is the exam fee: $155, with no published member/non-member split. One free retake is available within one year of your first exam session. Everything else is a separate line item, and prices vary by provider.

Cost ItemWhat the Sources Show
PVI1 exam fee$155 (issuer fee)
eITprep PVI1 guideListing shows $74.95 for six months; ETA's referral text advertises $59.95, an unresolved public conflict
Solar PV Training online course$199 for the legacy residential course, excluding hands-on lab and exam
Eastern West Virginia CTC program$599 listed for 2025-2026, subject to change; an older 2023 flyer shows $400 adult tuition
ExamRoom.AI remote proctoring$16 per two-hour session, only if remote testing is eligible
Maintenance$25 per year on the hands-on track

Note that the $50 member discount ETA advertises applies to a partner course, not the exam. And the college prices are provider-specific, not issuer-wide fees. Don't budget from a single listing. Our PVI1 certification cost breakdown tracks these line items in more detail.

Remote Testing: Read the Fine Print

It is tempting to assume you can take everything from your kitchen table. The sources do not support that promise. ETA's test-sites page offers ExamRoom.AI remote proctoring for non-hands-on certifications, while the FAQ discusses remote candidates still attending an approved school for hands-on credentials. PVI1 has a hands-on component, so exact knowledge-test remote eligibility is unconfirmed.

Confirm before you pay: Contact ETA or your approved school and ask specifically whether the PVI1 knowledge examination can be taken remotely, and what proctoring fee applies. Do not plan on a wholly remote certification, because the hands-on requirement still involves an approved trainer or school.

For timing questions, our PVI1 exam dates guide covers scheduling realities.

Test-Day Rules

ETA's general rules apply, and they are straightforward:

  • Bring photo identification.
  • Scratch paper is allowed but may need to be surrendered afterward.
  • A non-programmable or scientific calculator is permitted; programmable calculators may need to be reset.
  • Phones and other electronic devices are prohibited.

The published formula-sheet authorization names other ETA exams, not PVI1, and open-book permission is not verified. So assume you must have the key formulas memorized. That makes Domain 6 preparation even more important.

Sequencing Your Preparation

Rather than a generic plan, order your study around how the domains depend on each other. Terminology feeds calculations, calculations feed home energy estimates, and safety and codes connect to your hands-on demonstration. Here is one sequence that follows those dependencies. Our full PVI1 study guide offers more detail.

Week 1

Vocabulary and Background

  • Work through Domain 2 terminology with units attached
  • Skim Domain 1 history for quick wins
Week 2

Theory and Safety

  • Study Domain 5 theory of operation
  • Review Domain 3 installation and safety alongside your hands-on training
Week 3

Calculations and Estimating

  • Drill Domain 6 formulas with a non-programmable calculator
  • Apply them to Domain 7 household load estimates
Week 4

Codes, Project Management, and Timed Practice

  • Review Domain 4 using the code edition your trainer references
  • Cover Domain 8 project management
  • Run a full 75-question, two-hour timed session

For quick reference near the end, the PVI1 cheat sheet condenses the must-know facts. When you are ready to test yourself, use the PVI1 practice tests. Keep in mind that practice questions here are original and aligned to the competencies, not actual issuer exam items or an official mock exam.

PVI1 vs. NABCEP PV Associate

Candidates often weigh PVI1 against the NABCEP PV Associate credential. To keep this fair, the comparison is limited to the PV Associate, not NABCEP's PV Installation Professional, which is a different credential. I am not importing NABCEP's syllabus or eligibility details here, so check NABCEP directly for those.

PointETA PVI1
IssuerETA International
Written exam75 questions, two hours, 75% to pass
Practical componentHands-on skills demonstrated through an approved trainer or school
Exam fee$155
ValidityFour years with maintenance

The practical difference worth noting is the hands-on component built into PVI1. If an employer or jurisdiction names a specific credential, that requirement should drive your choice. Ask the employers you want to work for which credential they prefer.

Pay, Jobs, and the Value Question

The only hard earnings figure available is occupation-wide. The Bureau of Labor Statistics reports a May 2025 median pay of $53,140 per year ($25.55 per hour) for solar photovoltaic installers. That figure covers the whole occupation, not PVI1 holders specifically. It is not a PVI1 starting salary, and no measured certification premium was found. Anyone quoting you a precise PVI1 pay bump is guessing.

Where does PVI1 help? It documents both knowledge and demonstrated hands-on competency, which gives residential and commercial solar installation employers a recognizable baseline for entry-level hires. Browse our notes on PVI1 jobs, then weigh the numbers in our salary guide and worth-it analysis. Treat the credential as a way to demonstrate readiness, not a guaranteed raise.

Keeping the Credential Active

PVI1 runs on a four-year term. For the hands-on maintenance track, ETA requires:

  • 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 has a separate non-hands-on alternative with different requirements, but that is not the track that applies to PVI1, so ignore it when planning. Put the annual hours on your calendar from year one rather than scrambling in year four.

Frequently Asked Questions
