Automatic Solar Panel Cleaning System

Energy is still one of the most critical issues facing the world today. In India, energy access continues to be a critical issue for both urban and rural households. Approximately 60% to 70% of the country’s energy needs are still fulfilled using fuelwood and agricultural waste. Among renewable sources, solar energy stands out for its abundance and sustainability, making it a key solution for reducing reliance on petroleum-based electricity. However, in tropical regions like India, solar photovoltaic (PV) modules are frequently exposed to dusty environments. Accumulated dust on PV surfaces blocks sunlight and can reduce power output by up to 50% if not cleaned regularly. To combat this issue and enhance efficiency, an Arduino-based automated cleaning system has been developed to remove dust from PV modules effectively.
