Results of infrared research conducted on a photovoltaic system which works in an on-grid mode for over a year are presented in the article. The installation described is regularly shadowed by a cooling system. Thermograms of photovoltaic modules in strong and light shadow were conducted. These images show that even in very weak shadow the PV cells are overheated. This has led to small point damages in the amorphous panels and in the future it may also lead to the destruction of polycrystalline modules.
