Yes, solar panels are hot to the touch. When solar panels get hot, the operating cell temperature is what increases and reduces the ability for panels to generate. . Most solar panels have a rated “solar panel max temperature” of 185 degrees Fahrenheit - which seems intense. However, solar panels are hotter than the air around them because they are absorbing the sun's heat, and because they are built to be tough, high temperatures will not degrade them. Panels convert sunlight to electricity, minimizing heat buildup on roof surfaces. Solar panels help mitigate urban heat by shading. . It's an understandable concern—solar panels are dark, sit directly under the sun, and cover large parts of the roof. At first glance, they look like they'd trap more heat.
