While solar panels do get warm, they are not as hot as a dark roof exposed to direct sunlight. The insulation effect of the panels can actually lead to a cooler attic space compared to a roof without solar panels. . Solar panels convert sunlight into electricity through photovoltaic cells. The process generates some heat, but the amount is relatively minimal. . Solar panels don't make your house hotter and actually help keep your house cooler by reflecting some of the sun's heat away from the roof. This positive thermal effect is a direct result of two primary mechanisms: shading and ventilation. They can withstand ambient temperatures up to 149 degrees Fahrenheit (65°C).
