Photovoltaic (PV) solar panels generally produce electricity in the 6% to 15 % efficiency range, the rest of the solar energy being dissipated in thermal losses. To recover this amount, hybrid photovoltaic thermal systems (PVT) have been devised. These are devices that simultaneously convert solar energy into electricity and heat. It is thus interesting to study the PVT system experimentally for a particular climatic condition as part of a closed loop single phase water CDU ( coolant distribution unit ) in laminar forced convection. Results show that clear advantages regarding increasing open circuit voltage till +30% with a little decrease of thermal efficiency(±10/15%) are obtained in particular conditions by a single hybrid PVT water panel compared to separated productions.

Abstract

Photovoltaic (PV) solar panels generally produce electricity in the 6% to 15 % efficiency range, the rest of the solar energy being dissipated in thermal losses. To recover this amount, hybrid photovoltaic thermal systems (PVT) have been devised. These are devices that simultaneously convert solar energy into electricity and heat. It is thus interesting to study the PVT system experimentally for a particular climatic condition as part of a closed loop single phase water CDU ( coolant distribution unit ) in laminar forced convection. Results show that clear advantages regarding increasing open circuit voltage till +30% with a little decrease of thermal efficiency(±10/15%) are obtained in particular conditions by a single hybrid PVT water panel compared to separated productions.
