Thermal aspects of operation of the selected photovoltaic components

In the study the authors introduced the idea of the operation of the photovoltaic system with possibly low temperature of photovoltaic cell surfaces. The attention was paid both to PV panels which are very popular in Poland and to currently less popular PV roofing tiles. The selected solutions were characterized, which - in the authors’ opinion - have a practical impact on lowering of the temperature of operation of photovoltaic cells, and thus increase the system’s energy yield. Special attention was paid to the concept of operation of the hybrid PVT collector as well as the selection of roof substrate for PV roofing tiles. Potential benefits resulting from conducted works were indicated for various groups of recipients. The results of first tests and calculations were also presented, which confirm the need of further research works on this issue.
