What Does PV2 Stand For?

The Short Answer: What PV2 Stands For

In the context of this site, PV2 stands for Photovoltaic Installer/Designer (PV2). "PV" is the standard abbreviation for photovoltaic, the technology that converts sunlight directly into electricity. The "2" marks the second tier in ETA International's photovoltaic certification progression. The full credential name tells you its purpose: it certifies people who can both install and design solar electric systems.

If you landed here from a search for the acronym alone, you may want the broader background first. Our overview of what PV2 is and the companion piece on PV2 meaning cover related angles, while this article stays focused on the name itself: what each part signals, what the credential demands, and how to avoid confusing it with something else.

Who Issues the Credential

The Photovoltaic Installer/Designer (PV2) is a certification from ETA International (ETA). ETA publishes the competency requirements the exam draws from, maintains the eligibility checklist, and sets the fee, question count, and passing score. Testing is arranged through an ETA Certification Administrator, using either Trapeza online testing or a paper exam.

Knowing the issuer matters for a practical reason. Every fact about eligibility, renewal, and exam format should be verified against ETA's own documents, not against a forum post or a similarly named credential from a different organization. For a fuller walkthrough of the credential as a whole, see our page on what PV2 certification is.

Why the "2" Matters

The numeral signals that this is not an entry-level credential. ETA's current Photovoltaic Installer (PVI1) certification sits beneath it, and PV2 builds on that foundation. Two details from ETA's materials make the relationship concrete:

• PV2 supplements PVI1 knowledge. The PV2 competency headings focus on the added design, planning, and project-level skills rather than restating every prerequisite topic.
• A current PVI1 certification credits 40 of the 60 required training hours toward PV2 eligibility.

So the "2" is not decorative. It reflects a step up in responsibility: from carrying out installation tasks to understanding the reasoning behind a system's design.

What the Name Promises: Installer and Designer

The slash in "Installer/Designer" is doing real work. The credential is meant to show that its holder can operate on both sides of a solar project.

The installer side

Eligibility requires documented field work. The compulsory installation experience includes at least three systems of 2 kW or larger, and the candidate must reach at least 150 attested experience points that include every compulsory task. Wiring, mounting, testing, and commissioning are not abstractions for a PV2 candidate; they are things the candidate has already done and had attested.

The designer side

The competency headings reach well past the roof. Determining customer needs, conducting a site survey, selecting components, sizing the array, and understanding codes and standards are design-stage activities. A candidate has to connect a customer's load and goals to a defensible system layout, then carry that design through to commissioning.

The Acronym Trap: Other Credentials Share "PV2"

"PV2" is a short, reusable label, and several unrelated credentials and products use it. A web search for the acronym can surface material about a different certifying body, a different fee, or a different exam entirely. If you are preparing for the ETA credential, treat any source that does not name Photovoltaic Installer/Designer (PV2) and ETA International with suspicion.

Use this quick checklist to confirm you are reading about the right credential:

If a source quotes different numbers, it is almost certainly describing something else. For a deeper look at how the pieces fit, our guide to what PV2 means compares the common interpretations.

The 15 Competency Areas Behind the Name

ETA's competency document for the Photovoltaic Installer/Designer (PV2) lists numbered headings, and ETA states that examination questions derive from the certification competencies. Here are the 15 areas as written in that source:

1. History and Background of Photovoltaics (PV)
2. Additional PV Project Safety (the source document spells this "ADDITONAL")
3. How the Grid Works
4. Determining Customer Needs
5. Codes and Standards
6. Conducting a Site Survey
7. Components Selection
8. Array Sizing
9. Wiring the System
10. Energy Storage Systems
11. PV Mounting Systems
12. Project Management
13. Testing and Troubleshooting
14. Commissioning the System
15. Maintaining the System

How the Credential Is Earned

The name suggests a professional, and the path to it reflects that. Per ETA's PV2 checklist, a candidate must:

• Be at least 18 years old.
• Complete 60 contact hours of ETA-approved or equivalent photovoltaic training (a current PVI1 certification credits 40 of those hours).
• Complete OSHA 10 construction safety or an equivalent jurisdictional course.
• Obtain ETA Customer Service Specialist (CSS) certification.
• Document at least 150 attested experience points, including every compulsory task and at least two reference contacts.
• Agree to ETA's Code of Conduct.
• Pass the written examination.

That list is the main reason PV2 is not a casual, take-it-this-weekend credential. Most of the effort happens before exam day. Our detailed page on PV2 requirements and how to qualify expands on each item, and the PV2 training overview explains how the contact hours fit in.

Exam Mechanics at a Glance

Once you are eligible, the exam itself is a single written test. The fee and format come straight from ETA's Renewable Energy Certifications listing:

A 75% threshold on 100 questions means a candidate needs roughly three correct answers for every four. With a two-hour limit, pacing is manageable but not unlimited, so familiarity with calculation-style and code-reference questions pays off. ETA's general testing FAQ permits a nonprogrammable calculator, but it does not establish PV2-specific rules about reference books, so confirm what is allowed with your Certification Administrator before test day. For the scoring details, see what you need to pass, and for cost planning, the pricing breakdown. When you are ready to test your knowledge under realistic conditions, our PV2 practice tests mirror the style of the written exam.

Renewal: a point to confirm directly

ETA's materials contain a conflict worth flagging rather than glossing over. The PV2 checklist specifies 24 continuing-education hours over four years and $25 annual maintenance. ETA's general maintenance policy, however, distinguishes a standard route (40 hours over four years, or employer verification) from a hands-on route (24 hours plus employer verification), with $25 annual maintenance on both. Because the sources do not line up neatly, confirm the applicable PV2 renewal route with ETA before you plan your continuing education.

Where the Credential Gets Used

The title tells you who benefits: people whose work spans solar design and installation. In practice, that means roles such as installation leads, field supervisors, system designers, and technicians who carry responsibility for how a project is planned and delivered. Solar contractors, installation companies, and firms that manage PV projects are the natural employers, and a credential that verifies both field experience and design knowledge helps a candidate stand out in those settings.

We deliberately do not quote salary figures here, because ETA does not publish certification-specific earnings and we will not invent them. If compensation and career value are your main questions, our analyses of earnings, job opportunities, and whether the credential is worth it discuss those qualitatively.

Sequencing Your Preparation by Domain

This is the one place we will talk about study scheduling, and it is tied directly to how the 15 domains relate to each other. Because the competencies build from context to design to execution, studying them in that order makes the later material easier to absorb.

Finish with timed practice. Our full study guide lays out a longer plan, the cheat sheet condenses the must-know facts, and the difficulty guide and pass rate discussion help you calibrate expectations. Check scheduling and testing windows before you commit to a test date.
