With growing costs of electricity and concern for the environmental impact of fossil fuels, implementation of eco-friendly energy sources like solar power are rising. The main method for harnessing solar power is with arrays made up of photovoltaic(PV) panels.Accumulation of dust over solar panel reduces their efficiency in energy generation considerably and emphasizes the need to keep the panel’s Surface as clean as possible. Current labour-based cleaning methods for photovoltaic Arrays are costly,time consuming and lack monitoring capabil-ities.This paper describes about an IoT controlled solar panel cleaner that provides a cost effective and scalable solution for the removal of soil and dust.Water is used for cleaning the panel surface and a cooling system is also implemented. By this,efficency and output increases.
