Can photovoltaic panels be used on rooftops?

Photovoltaic (PV) panels are commonly used for on-site generation of electricity in urban environments, specifically on rooftops. However, their implementation on rooftops poses potential (positive and negative) impacts on the heating and cooling energy demand of buildings, and on the surrounding urban climate.

Why do photovoltaic panels increase roof temperature?

The shading effect of the photovoltaic panels makes the roof temperature in the shading area higher than that in the unshaded area. This is because the photovoltaic panels store a certain amount of heat during the day when the irradiation is abundant, radiating heat with the shading area at night, causing its temperature to rise.
