Performance of Solar Panel in Presence and Absence of Dust

Abstract

Over the years, solar photovoltaic panels have become the important source for utilizing the solar power, due to their characteristics of being renewable, safe and pollution free. Producing electricity using these photo voltaic panels is comparatively a profitable method. But the aggregation of dust over the panels reduces the output power of the solar cells further lowering the efficiency of the solar panels specifically in the regions having high rate of dust, low frequency and high rain. This blocks the sunrays from reaching the panels, decreasing its performance. In this paper, an experimental setup, built to measure the output power of the solar panels is explained. Experimental setup for testing the solar panels in different parameters is prepared. Testing is done with and without dust on the solar panels at different intensities. The experimental results indicate a comparable study of how the output of a dusty panel is reduced in comparison with a clean panel. Also increase in temperature of the panels reduces the output of the photo voltaic cells is projected through the results.
