Blocking the Sun with Solar Panels

To avoid the heating effect of solar radiation inside the building, panels of thermal solar collectors or areas with photovoltaic panels can be used. By this, the reduction of excessive indoor temperatures (and thereby reduced cooling demand) is combined with renewable energy sources. It can be distinguished between fixed and variable shadowing elements.

Steep roofs can also be shadowed by solar panels. The cooling effect during heat waves is better when these panels are not integrated in the roof. The gap between the modules and the surface improves the circulation of air.
