Abstract:

Photovoltaic- thermal systems are very popular for gaining both thermal and electrical energy from same surface. In this study, thermal gain of black colored absorber plate that placed at beneath of PV panel was investigated experimentally. For this purpose, it was designed that copper tubes heat exchanger. Also it was designed that a black painted aluminum absorber plate. Absorber and heat exchanger joined by means of thermally conductive adhesive. Finally, absorber was placed to beneath of the PV panel and it was insulated using heat insulation material. Also absorber system was integrated with a water heating system. Thermal gain of absorber plate was investigated for different climatic conditions. Research was conducted for different solar irradiance, ambient temperature, wind speed, relative humidity values. Results show that absorber temperature reaches up to 70 - 80 °C before the cooling. Also absorber, gained that well amount solar thermal energy. This energy can be used for water heating systems easily. Also absorber temperature can be decrease to optimum value by means of water heating system.
