In many instances, a solar cell can get as hot as 65°C, causing the panel to become less efficient and therefore produce less power. If a panel with a temperature coefficient of -0.4%/°C were to reach an extreme heat of 65°C, it would reduce output by as much as 26% (-0.4% x 65). marooned comicWeb9 de oct. de 2024 · Oct 15, 2024 at 9:01. Add a comment. 0. To explain it crudely, the earth is warmer because the surface is warm, not because the air is warm. Solar panels don't contribute to global warming because, while they do absorb energy from light, they also reflect a lot of light back out into the atmosphere. marooned at sea
