6 FAQs about [What is the rated power of photovoltaic panels]

What does rated power mean on a solar panel?

In simple terms, rated power refers to how much electricity a solar panel can generate in optimal conditions. In other words, the solar panel would generate power at the levels the rating suggests in direct sunlight, at the perfect temperature, and positioned at an optimal angle. For example, suppose you have a 400W rigid solar panel.

Do solar panels have a high efficiency rating?
