Solar Panel Cleaning System Using Voltage Comparison

The pollution not only causes harm to the surroundings but also deposits on the solar panel. Besides pollution dust and debris carried by the wind also deposit on solar panel’s surface. Soiling reduces the amount of sunlight incident on the surface of the panel thereby reduces the output produced. To avoid that manual cleaning is done at present. But the process is not continuous and not done periodically so there is a loss of output voltage and current produced from the panel. Thus an automatic solar panel cleaning system is designed, which detects dust by comparing the reference voltage and present voltage measured and cleans by itself until the dust removed.
