Solar Glossary of Terms

Are you interested in solar electricity, but not sure what “photovoltaic conversion efficiency” means? You’re not alone. In fact, because technical terms like these come up frequently, especially in discussions of photovoltaics (PV), we prepared this glossary of terms. In it you will find definitions of many important terms having to do with electricity, power generation, concentrating solar power (CSP), solar heating, solar lighting, and solar electricity, also known as PV…
