PVT Performance Prediction
Abstract
Photovoltaic Thermal (PVT) hybrid modules producing electricity and heat in parallel are becoming more relevant in the Solar Thermal market. Especially PVT modules in combination with heat sinks operating in low temperature ranges like heat pumps are showing perfect conditions for that kind of combination. One important topic for a broader market implementation and distribution will be a clear and overall performance characterization with respect to electrical and thermal power measurements and their interaction. The presented project has validated a method for a junction (module) temperature forecast based on the thermal behavior of PVT’s under consideration of mean fluid temperature, ambient temperature and wind speed. This approach will give the required link between thermal collector testing and electrical PV module characterization and provide a clear distinction of responsibilities for the thermal and PV experts and laboratories.
