Integrating Automation and Sustainability: Arduino-Based Solar Panel Cleaning System for Renewable Energy Optimization

This paper realizes the design and implementation of an automatic cleaning system for solar cells through Arduinos, so they can work better and last longer with less maintenance. The system combines an Arduino microcontroller, servo motors, water spray devices, and sensors to automate the cleaning process. This not only eliminates dirt, dust, or debris; it ensures consistent efficacy. Testing showed that output from panels improved significantly after cleaning. Each time only 2.4 liters of water and 0.05 kWh of power were used, for a minimal consumption level. Its modular and inexpensive design makes it suitable for residential and small-scale use. From the optimum interval determined for monthly cleaning, a balance of efficiency gains and cost may be struck. This project forms a practical, not to mention scaleable, and sustainable solution for maintaining solar panels. Use of renewable energy technologies will further reduce the environmental impact. Next-generation developments might incorporate advanced dirt recognition or the convergence of renewable energy integration into their capabilities.
