PVI1 practice questions - frequently asked questions

Plain answers about how PVI1 Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real PVI1 exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The PVI1 exam spans 8 domains: HISTORY AND BACKGROUND OF RENEWABLE ENERGY; PHOTOVOLTAICS TERMINOLOGY; INSTALLATION AND SAFETY; CODES AND STANDARDS; THEORY OF OPERATION; APPLIED CALCULATIONS AND FORMULAS; ESTIMATING HOME ENERGY NEEDS; PROJECT MANAGEMENT. Every practice question on this site is tagged to one of these domains.

The PVI1 exam has 75 questions and is completed in 2 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
