Experimental Study on Glazed mc-Si Solar Photovoltaic/Thermal(PVT) System

AbstractSolar photovoltaic/thermal(PVT) is a hybrid collector that combines solar photovoltaic cells and thermal collector to convert solar energy into two types of useful energy, i.e. electricity and thermal energy, simultaneously. A PVT collector converts more solar energy per unit surface area into useful secondary energy sources than a combination of separate PV modules and solar thermal panels. This paper presents the 9 months experimental results of a 900Wp mc-Si solar PVT system that was composed of 6×150Wp mc-Si glazed PVT collectors developed in Singapore. The analyses on the operational data reveal the PVT system under the test can achieve the 41.08% of average monthly conversion efficiency. The two stagnation tests, dry and wet test, were performed and the results showed that the maximum temperature of water under dry stagnation test is 64°C, while that under wet stagnation test is 65°C
