Solar Panels Cleaning?

Yes, solar panels need cleaning to remain efficient. Dust, pollen, bird droppings, and pollution eventually cover the surface, reducing the amount of sunlight that reaches the photovoltaic (PV) cells. Although newer solar panels can partially clean themselves with rain, areas with little rain or high dust levels may need manual cleaning.

Regular maintenance of solar panels is very important to ensure the panels generate steady energy and minimize the chances of damage, which maximizes returns on investment. We recommend checking your panels regularly and cleaning them as needed to avoid losing up to 25 percent of energy due to grime and dirt.

How to Clean Solar Panels Best.

When washing  solar panels, the goal is to remove debris without scratching or damaging them. Here are some key steps:

•  Soft Brush or Sponge: Use a soft brush that won’t scratch the panels.
•  Warm Water and Mild Soap: Avoid harsh chemicals; a mild cleaning agent is best. 
•  Low-Pressure Hose: High-pressure washers may damage the panels or wiring.
•  Re-Cleaning: Clean every 6 to 12 months, depending on local conditions.

For the best results, clean the panels from bottom to top to avoid streaking. If your panels are hard to reach, consider hiring professionals. With help from Solar Dream, your panels will remain efficient and their lifespan will improve.

•  Use Cleaning Solution: Combine warm water with a mild, non-abrasive soap.
