This is different from solar thermal which uses the sun’s heat to generate hot water.

In fact, solar PV panels become less efficient as they get hotter. Thus, typical PV installations on rooftops are designed in a way that there is natural ventilation to provide some cooling for the PV modules. For example, by having a distance between the solar panels and the actual roof surface (which also heats up during hot days).
