【 摘 要 】

Power output will decline when foreign objests covered on PV panels. In this paper a system dsigned to detect the power output decline caused by foreign objests in different situations effectively. It is mainly composed by temperature detection module, irradiance detection module, power detection module, and embedded minimum system module. A power output model of foreign objests on surface is analized and a number of experiments were conducted in indoor and outdoor. The result shows that characterictic measured is consistent with the theoretical model compared with that of a clean panel. Therefore, this system can detect the coverage of the foreign objects on panel correctly.
