As solar energy becomes increasingly popular in Pakistan and around the world, experts are reminding users that regular cleaning of solar panels is essential to maintain optimal efficiency. Dust, bird droppings, and pollution can reduce a panel’s energy output by as much as 20%, especially in dry and dusty regions.
Here’s how to clean your solar panels safely and effectively:
-
Choose the Right Time:
Clean your panels early in the morning or late afternoon when they are cool. Cleaning hot panels can cause sudden temperature changes that may lead to cracks. -
Use Soft Materials Only:
Avoid abrasive brushes. Instead, use a soft cloth or sponge with lukewarm water. A mild, non-abrasive soap can be used if necessary. -
Avoid High-Pressure Water:
Never use a pressure washer. The force can damage the panel’s surface and seals. A garden hose with a gentle spray works best. -
Stay Safe:
If your panels are installed on a roof, use proper safety equipment or hire a professional to prevent accidents. -
Regular Inspections:
Alongside cleaning, check for shading from nearby trees, loose wiring, or damage to the glass. Regular maintenance ensures long-term performance.
Energy experts recommend cleaning panels every 3 to 6 months depending on your environment. In highly dusty areas, monthly cleanings may be necessary.
By following these simple steps, solar panel owners can ensure maximum efficiency and prolong the life of their investment—helping both the environment and their electricity bills.
