Experimental Study on Power Generation Efficiency of Solar Panels

In order to make better use of solar energy resources, according to the application of solar power in Nanjing area, the law of generating efficiency when the solar panel in light of different wavelengths is experimented and analyzed, the experi mental study of generating efficiency under the different irradiation angles is carried out. In this paper, the test program for the generating efficiency of solar panel is described, by the filters, four wavelengths of the sun＇s rays are obtained. For the combination of solar panels arranged,five combinations are designed, and each combination is investigated experimentally. The experiment results show that in the Nanjing area weather, at 12 to 14 o＇clock solar generating efficiency is the highest; The wavelength of light which greater than 600nm provides the maximum efficiency of power generation. In practical terms, four solar panels in parallel to provide the strongest current, four in series to provide the maximum energy of voltage. The results of the study can provide a good reference for better utilize of the solar resources.
