Solar panels can generally clean themselves. However, dust or other substances like bird droppings, lizard droppings, and other dirt can build upon our solar panels thereby affecting the amount of electricity generated.
Here’s how to clean your solar panel:
- Use a hose to rinse your panels from the ground. There’s no need to climb up and clean if you don’t have the right experience and skills. You can contact a professional for that.
- Clean your solar panel in the morning or in the evening when there’s no sun. This is to prevent smears and watermarks. Using cold water on a very hot panel will cause it to crack. It’s preferable you clean the panels in the morning. The dirt would have been softened by the dew overnight, making it easier to clean.
- Be gentle while cleaning because solar panels are fragile and can crack.
- Avoid using abrasive materials or scratching the panel. Scratches can lead to low functionality of the panel. Instead, use a soft brush or foam with a mild soap (not detergent).
If the dirt is not visible or affecting the performance of the solar panel, it’s not necessary you clean it at all.
