Build Your Own Solar Panel

Solar panels don’t work when it’s too hot/sunny?

is this fact true? – its a limitation to solar panels during summer when it’s in extremly hot countrie. I’ve heard it from my science teacher .. please give detail if you have any and any more benefits/limitations is welcomed .. Thank you !

Solar PV (photovoltaic) panels do indeed get less efficient when they heat up.

If you look at the I-V power curves on the spec sheet for these rooftop panels (PDF):

you’ll notice that they have different curves for different temperatures. But they do still produce power, certainly. I have an array on my roof, and it still manages to max out the inverter on a hot summer day. But I do notice that the top row, which is hotter due to heat rising from those below, consistently puts out a few less watts than the bottom row.

So more sun is certainly better; direct light is exactly what’s needed. But hot panels due to poor air circulation or high ambient temperature does cut into efficiency.

(Solar thermal, of course, is a different story)
