自然環境下における太陽電池の出力特性

抄録

The electric power generated by the photovoltaic array depends on the insolation and cell temperature, and the cell temperature depends on the insolation, ambient temperature and wind speed. In this study, it is shown that the cell temperature and output power can be calculated by considering the heat balance and the voltage-current characteristics of solar cells. A photovoltaic power generation system connected with a commercial power source was constructed, and a long term test of the system under natural weather conditions was performed. From the experimental results, it was confirmed that the method of calculation yielded a close approximation.
