수식 PV/Thermal 복합 시스템의 설계 및 성능실험

PV/Thermal combined systems can produce the electricity and thermal energy which can be utilized in buildinsg. Hot air can be extracted from the space between the PV panel and roof, so the efficiency of the PV module increases. At the same time the hot air from the collector can be used for space heating or hot water in buildings. This study describes a basic type of PV/T collector using water as thermal medium. In order to analyze the performance of the collector, the experiment was conducted. Experimental results were analyzed for the system's thermal and electrical performance: the results show that the thermal efficiency was 17% average and the PV efficiency was about 10.2%~11.5%, both depending on solar radiation, inlet water temperature and ambient temperature.
