Solar panels can slightly increase the temperature of a roof, but the effect is typically minimal and largely depends on various factors such as climate, panel design, and ventilation.  Solar panels absorb sunlight and convert it into electricity, but they also reflect a portion of the sunlight, which can reduce the amount of heat absorbed by the roof compared to bare roofing materials.

One of the advantages of solar panels is that they provide a layer of protection and insulation for the roof underneath.  They act as a barrier between the sun's rays and the roof's surface, which can help reduce heat transfer to the interior of the building and potentially lower cooling costs.  Additionally, solar panels are often installed with a gap between the roof surface and the panels, which allows for air circulation and helps dissipate any heat that is generated.

If you're concerned about the potential heat impact of solar panels on your roof, it's recommended to consult with a professional solar installer who can assess your specific situation and provide guidance based on factors such as roof condition, orientation, and local climate.
