Performance Analysis of Solar Pv Panels Using The Developed Automated Cleaning System

摘要

Solar energy is tremendous available as a most important energy source. The solar cells are usedfor many applications, including street lights to generate luminescent night. The accumulation of dust particles,deposits left by birds or the fallen leaves, on the surface of photo-voltaic PV panel will reflect the incident lightfalling on the panel, preventing a portion of the radiation from being used. This problem could reduce the abilityof cells to allow free entrance of photons and absorb solar energy, which greatly affects its efficiency, reducingthe lifetime of its storage power after a few months from its instillation, leading to a permanent or long-termfailure, especially in the desert areas. Other factors such as panel orientation or panel surface material cancontribute to the deposition of the impurities. Here in this work it find out the effect of cleaning of solar panel onthe efficiency of the solar plate. It calculates the efficiency of solar panel before cleaning and after cleaning, italso calculate the effect of different parameters responsible during the cleaning of solar panel. The parametersresponsible for cleaning are feed speed, roller speed, feed depth, no. of pass of roller. Through experiment it isfound that the value of efficiency for all isolation is maximum in case of solar panel without dust. From thegraph it is found that as the rotation speed of the roller increases the efficiency of the solar system decreases.From the experimental analysis it is also found that the value of efficiency is maximum for feed velocity 0.1 m/swhere as it is minimum for feed velocity 0.3 m/s.
