Avoid Harsh Chemicals


When cleaning solar panels, steer clear of harsh chemicals, ammonia-based solutions, or abrasive detergents. Chemicals can damage the protective coatings on the panels, reducing their efficiency and potentially voiding warranties.



Proper maintenance and cleaning are crucial for maximizing the efficiency and longevity of solar panels. Regular inspections, professional maintenance, and monitoring systems are essential for early issue detection. Additionally, gentle cleaning with water and soft brushes is vital to remove dirt and debris without causing damage. By following these maintenance and cleaning tips, solar panel owners can ensure their systems operate at peak efficiency, contributing to a greener and sustainable energy future.
