DESIGN AND FABRICATION OF SOLAR PANEL CLEANING MECHANISM

In this project, an ESP32 microcontroller-based solar panel cleaning mechanism is designed and implemented. Using a 1 HP water motor pump, a gear motor with a sproc ket-chain mechanism, and a wiper assembly, the system is made to automatically clean solar panels in order to maximize solar energy output. The electrical characteristics of the solar panel are continually monitored by voltage and current sensors. The BTS7 960 motor driver regulates the gear motor that moves the panel wipers. Real-time panel voltage, current, and system functioning status is shown on a 20x4 LCD display. A 12V 8A battery coupled to two 50W solar panels powers the system. The add-on water spra ying panel's 1 HP water motor is managed by a relay module. Through IoT-based automated control, the suggested solution increases solar panel efficiency, lowers the cost of manual cleaning, and guarantees steady energy production.
