Electrostatic Precipitation for Solar Panel Optimization

Abstract

Solar energy is a vital component of sustainable energy solutions, offering a renewable and eco-friendly alter- native to fossil fuels. However, the efficiency of solar panels is significantly affected by dust accumulation, commonly referred to as soiling, which can reduce energy output by up to 40 This paper proposes an innovative, waterless dust removal system utilizing electrostatic forces to enhance the performance and durability of solar panels. The system operates by generating a high-voltage electrostatic field that induces charge in dust parti- cles. These charged particles are then repelled and dislodged from the panel surface using two vertically spaced electrodes—one transparent and fixed, and the other a moving non-transparent electrode. By eliminating direct contact with the solar panels, this approach significantly reduces wear and extends the lifespan of the panels. Moreover, the system does not rely on water, making it particularly advantageous in arid and water-scarce regions. Unlike traditional mechanical systems, the electrostatic method is energy-efficient and minimizes maintenance costs over time. The proposed system offers a transformative solution for maintaining solar panel efficiency and longevity, providing a sustainable, cost-effective, and scalable alternative to existing cleaning technologies. Future work will focus on optimizing power consumption, improving system robustness, and assessing large-scale implementation for commercial solar farms.
