Abstract: The power output performance of PV module in a PV system is significantly affected by partial or complete shading of the solar cells and the specific effect depends on the PV module configuration, solar cell types, shading types, and presence of bypass diode. This paper investigates the impacts of partial shading on the power output performance of poly-crystalline and amorphous silicon PV modules. Several experiments including indoor experiment and outdoor experiment make a main role to collect data in this study. The current-voltage and power output performance of PV modules under different types of shading condition were measured for comparison and analysis. Besides, a shading test with shelter far from the PV module was conducted to put the whole experiment close to real operation conditions. And a site survey at the solar PV test facility in Tung Chung was also be conducted.Some conclusions of shading effect on power output performance of PV module was drawn, and the best solution to deal with each shading condition were proposed according to the experimental results.Then some advices on design and installation of PV panels were given to the PV industry as guiding function.
