The photovoltaic (PV) solar panels are getting bigger applications in the practice. Their efficiency isbetter at lower temperatures. Normally the panels are cooled with the ambient air (in this case the gainedheat is dissipated to the surrounding without any application). A successful combination of photovoltaicsolar panel and solar collector is the so called photovoltaic-thermal (PV/T) solar panel. There are somesignificant advantages of the PV/T panels – aesthetic advantage over the PV panels, usage in placeswhere the area is limited, reduction of the installation costs and architectural unity between roof and PV/Tpanels. The article analyses two solar panels – the PV solar panel of the type polycrystalline silicon (pc-Si) and the PV/T Solar Module CPVT60P250 (both solar panels are produced by the Crane Companyusing silicone cells from EKS – Solaris GmbH). Some tests are implemented and a comparison betweenthe efficiencies of both panels is done.
