Design and development of waterless solar panel cleaning system

Abstract

With around 300 clear and radiant days in a year, the determined sun-based vitality occurrence on India’s property zone is around 5000 trillion kilowatt-hours (kWh) every year. The sunlight-based vitality accessible in a solitary year surpasses the conceivable vitality yield of the majority of the petroleum product vitality holds in India. The everyday normal sun-based power-plant age limit in India is 0.20 kWh per m2 of utilized land territory. Efficiency of solar panels are poor when they are not clean. Water based manual cleaning is costly, brings about ecological damage. Apart from leading to an electrical hazard, water-based cleaning leaves deposits, and causes scratches because of scouring. With manual cleaning, there is a danger of harming the covering of the boards. Our design utilizes nylon bristled brushes making no harm to the panels. No weight or stress is applied on the photovoltaic cells. The cleaner robot is self-fuelled, and programmed. It navigates through the entire length and comes back to the docking position. This completes one work cycle. Cleaning is finished utilizing exceptionally planned brushes, lifting the residue far from the boards. The cleaner robot can be retrofitted to suit existing or customized solar panels.

Effect of Water Cooling and Dust Removal on Solar Photovoltaic Module Efficiency

“…The maintenance ensures the panel's surface is cleaned and cooled, maximizing energy production. The system is also connected to an IoT part to enhance further the system, which can be controlled remotely using a smartphone [21,22]. This paper uses the Blynk application with the ESP-32's built-in Wi-Fi.…”

“…20% coverage has the highest output power compared to the rest. The results of this experiment demonstrate that even a small amount of dust and debris can significantly reduce the performance of a solar module, which is an essential consideration for the design and placement of solar modules in real-world applications [20][21][22]. Cleaning the PV module increased the power generated compared to PV without the cleaning system.…”
