When a solar panel is hot, the difference between the rest state and the excited energy state is smaller, so less energy is created. The opposite happens when a solar panel is cooler. Inside a cool solar cell, the electrons are still getting excited by the sunlight and they''re easily able to move up to the higher level of energy.
Solar technologies use clean energy from the sun rather than polluted fossil fuels. There are two main types: solar thermal, which uses solar energy to heat water, and solar photovoltaic (PV), which uses solar cells to transform sunlight into electricity. Global solar adoption is increasing as a result of declining costs and expanding access to clean energy (SDG 7).

On a smaller scale, solar panels that harness thermal energy can be used for heating water in homes, other buildings, and swimming pools.
Although solar panels absorb energy from the sun, hotter temperatures actually make them less efficient. Asked by: Liam Farmer, Birmingham Surprisingly, they perform worse as the temperature rises! Solar panels work by using incoming photons to excite electrons in a semiconductor to a higher energy level.
While it is easy to assume that blazing sunshine would boost the performance of solar panels, generating more power, that is not necessarily the case. "A really hot day, you'll actually produce less power because the solar panel gets so hot," engineer and solar analyst Finn Peacock said.
But despite their growing popularity, there are still some lingering misconceptions about how solar cells work, especially in very hot weather. "A solar panel is a bit like the silicon chip inside your computer, if it gets too hot it doesn't work quite so well," University of WA resources scientist Ray Wills said.
