To Investigate the Dust Particles and Improve the Performance of Photo Voltaic Panels by Using Sliding Cleaning Technique

Solar energy is considered the best source of renewable energy among all the energy sources. Aleksandra Stoletov for the first time designed a solar panel which is based on photoelectric effect. Due to cheapness and easy availability the solar panels are of great interest. The major factors which are responsible for decreasing efficiency and power of solar panels are dust accumulation, high temperature, snow and dirt on the surface of solar panels. Spots of different densities, shapes and locations also decrease the efficiency and power. We have used automatic sliding cleaning wiper technique to clean the un-coated panel. A prototype which comprised of cleaning robot and cloud interface also use for cleaning the dust accumulated on the surface of solar panels. Moreover, robotic arm, smart cleaning system and solar tracking system are also use for cleaning purpose, but they are very expensive. For area wise analysis of PV cells, we have considered two solar panels, in which one is dirty and the other one is clean. Both are inclined at 23.5ْ horizontal to the earth surface. It has found that short circuit current (ISC) of the clean panel as compared to dusty is greater.
