Automatic Cleaning of Solar Panels Using Delta PLC

In this paper a novel design is to be developed which uses PLC based automatic cleaning of solar panels. A tool is designed based on the array size, and water pumping/sprinkling mechanism is designed based on the amount/nature of dust accumulated. This design is a smart panel cleaning system for PV that provides a cost-effective and scalable solution for the removal of soil and dirt. It will automatically and remotely remove the dirt at a fraction of the cost of manual cleaning. In terms of daily energy generation, the presented automatic-cleaning scheme provides about 30% more energy output when compared to the dust accumulated PV module.
