Abstract: The solar panel works, when sunlight imparts on surface of solar panel. Amount of light that impart on solar panel is directly proportional to the energy generated through it. More the light that imparts more is the power generation. Due to the upwards angle of solar panels, there is lot of collection of dust and bird excreta. This reduces the amount of light that impact on the panel and reduces the panel output hence efficiency gets decreased. The solar panel manufacturers and installers claimed about the projected energy figures that based on the optimum performance of clean solar panel. Due to increasing the dirt on solar panel that can adversely affect the panel’s ability to achieve desired output. This is a big challenge in this area; so it is necessary and important to clean the solar panel in order to protect and get more power output. So we have designed and developed the automatic machine which will clean the solar panel and improve the panel efficiency & thus reducing the human effort. This low cost solutions very useful in the sector of non conventional energy.
