Energy efficiency enhancement of solar PV panel by automatic cleaning technique

Abstract

Globally, Renewable Energy Resources (RES) are playing a vital role for satisfying energy requirements. Since, RES is more finely comparable to fossil fuels, and it delivers a very low amount of Greenhouse gases. RES includes wind, solar, biomass, tidal and hydropower. Among them, the harnessing rate of energy from solar and wind farm has rapidly increased due to its unlimited amount of renewable energy production, which can be bung in an endless manner. Recent years, solar photovoltaic panels are popular in decentralized power generation whereas the efficiency of panels are affected due to environmental factors such as environmental conditions, atmospheric temperature, deposition of dust and sand particles on solar PV panels. The research proposed a new automatic solar PV cleaning mechanism, respectively. A prototype model has been developed. The cleaning has been performed per day, two times based on LDR signals. Depends on LDR’s commands, DC motor move forward direction when it reaches the relay switch, then motor reveres back to original position. From the experimental validation, the developed model working satisfactory.
