What Is A PV2?

What a PV2 Actually Is

In this context, a PV2 is a Photovoltaic Installer/Designer (PV2) certification issued by ETA International (ETA). It sits in ETA's Renewable Energy Certifications family and recognizes a technician who can do more than mount panels and pull wire. The "Designer" half of the title matters: a PV2 candidate is expected to understand how a system is conceived, sized, specified, documented, commissioned, and maintained, not only how it is physically assembled.

The acronym is shared by other, unrelated credentials in other industries, so be careful when searching. Everything on this page refers only to the ETA solar credential. If you want the shortest possible definitions, the site also has pages on what PV2 is, what PV2 stands for, and the meaning of PV2. This article goes deeper into how the credential works in practice.

Who Issues It and How the Exam Works

ETA International publishes the PV2 competency requirements and administers the examination. According to ETA's current Renewable Energy Certifications listing, the exam parameters are:

Testing is arranged through an ETA Certification Administrator, using either Trapeza online testing or paper. You do not simply buy a seat on a public calendar; you coordinate with an administrator who proctors the sitting. For scheduling logistics, see PV2 exam dates and scheduling, and for the full money picture, including costs beyond the exam fee such as training and prerequisite certifications, see the PV2 certification cost breakdown.

The 75% threshold means that on a 100-question exam you can miss roughly one question in four. That sounds forgiving until you notice how broad the competency list is. A candidate who is strong on wiring but weak on codes, storage, and project management can burn through that margin quickly. Our page on the PV2 passing score unpacks what the threshold means for your preparation.

The "no hands-on exam" caveat

ETA's overview lists no separate practical examination for PV2. Do not read that as "no hands-on requirement." The experience checklist, covered next, demands documented, attested installation work. The written test is the only exam, but the field experience is a gate you must clear independently.

The Eligibility Stack Before You Can Test

PV2 is not an entry-level, walk-in exam. The ETA PV2 Process and Experience Checklist lays out a layered set of requirements. In summary:

1. Age: at least 18 years old.
2. Training: 60 contact hours of ETA-approved or equivalent photovoltaic training. Current PVI1 certification credits 40 of those 60 hours.
3. Safety: OSHA 10 construction safety, or an equivalent jurisdictional course.
4. Customer service credential: ETA Customer Service Specialist (CSS) certification.
5. Experience: at least 150 attested experience points, including every compulsory task and at least two reference contacts.
6. Installation minimum: the compulsory experience includes at least three systems of 2 kW or larger.
7. Conduct: agreement to ETA's Code of Conduct.
8. Examination: a passing score on the written exam.

The experience points are the part candidates most often underestimate. They must be attested, they must cover every compulsory task, and they require reference contacts who can vouch for the work. Start documenting jobs early rather than reconstructing them from memory later. A fuller walkthrough is on the PV2 requirements page, and if you are still deciding on a training path, the PV2 training overview is a good companion.

What the 15 Competency Areas Cover

ETA's PV2 competency document (copyright 2019, currently linked by ETA) lists 15 numbered headings. ETA states that examination questions derive from the certification competencies. Importantly, ETA does not publish percentage weights for these areas, so treat them as an unweighted map of what can be tested rather than a blueprint with known proportions. The headings below reproduce the official names, including ETA's own spelling in the second one. For a deeper per-area treatment, see the complete guide to all 15 PV2 content areas.

How PV2 Builds on PVI1

PV2 is designed to supplement PVI1 knowledge. That is the reason the competency list reads as it does: it does not exhaustively restate every installer fundamental, so the 15 headings alone do not guarantee that prerequisite topics are fully covered on the exam. You should assume that core PV fundamentals from PVI1-level work remain fair game even where they are not a numbered heading.

If you are weighing the step up, the PV2 difficulty guide explains where candidates typically feel the jump.

Who Hires PV2 Holders

The credential is relevant wherever solar projects are scoped and delivered by people who must understand both the field and the design logic. Typical employers and roles include:

• Residential and commercial solar installation contractors that want crew leads or lead installers who can interpret designs and verify work.
• Design and engineering support teams at solar firms, where site surveys, array sizing, and components selection are daily tasks.
• Electrical contractors expanding into PV that need staff who bridge general electrical work and solar-specific design.
• Project coordinators and project managers who oversee installations, commissioning, and handoff.
• Operations and maintenance providers responsible for testing, troubleshooting, and keeping systems producing.

ETA's certification does not by itself promise a particular wage, and this article does not quote earnings figures. For a discussion of how employers value credentials like this, see PV2 jobs, the PV2 salary guide, and the PV2 ROI analysis.

Staying Certified: The Renewal Question

The certification term is four years, but the maintenance requirements need care, because ETA's own documents do not line up neatly:

• The PV2 checklist specifies 24 continuing-education hours over four years and $25 annual maintenance.
• ETA's general maintenance policy distinguishes a standard route (40 hours over four years, or employer verification) from a hands-on route (24 hours plus employer verification). Both carry $25 annual maintenance, and the overview marks hands-on as not required.

Sequencing Your Preparation by Domain

Because ETA publishes no domain weights, a sensible plan front-loads the areas that are both calculation-heavy and unfamiliar, then ties the softer areas together. A compact way to order it:

For a broader plan, see the PV2 study guide, and keep the PV2 cheat sheet handy for last-week review. When you are ready to test your recall under realistic conditions, run through the PV2 practice tests and review every missed item by domain. Note that ETA's general testing FAQ permits a nonprogrammable calculator but does not establish PV2-specific book permissions, so confirm what you may bring with your Certification Administrator rather than assuming open-book rules.

A note on data: no official pass rate is published in the sources used here, so treat any specific figure you see elsewhere with skepticism. The page on the PV2 pass rate discusses what can and cannot be known. If you want to practice with exam-style items now, head back to the main practice test site.
