Solar farms keep the neighbourhood cool, inspecting solar panels in broad daylight
The Sun may be fading fast here in the northern hemisphere, but the number of solar panels installed here in the UK and elsewhere continues to grow by leaps and bounds. As the area of land covered by solar panels increases, have you ever wondered if converting all that solar energy into electricity is affecting the local environment?
The answer is yes, at least in arid ecosystems, according to a team of researchers at the UK’s Lancaster University, Ludong University in China, and the University of California Davis in the US. They studied two large solar farms – one in California and the other in China’s Qinghai province – and found that the facilities were cooler than their surroundings. This was based on satellite temperature observations taken before and after the installation of solar panels and, in the case of the California facility, measurements taken on the ground.
Both solar farms created “cool islands” that extended about 700 m from the perimeters of the facilities. The cooling effect was significant, with land surface temperatures about 2 °C cooler 100 m from the edges of the solar farms.
Excellent Tips And Tricks On Roof Repair

Both conditions create circumstances that make it easy to destroy your roofing tiles, so only go up there if you have to when the temperature is extreme outside.
