Do I need to clean my solar panels?

Have you been wondering why your solar power output has suddenly dropped?

The dirt buildup on your solar panels could be to blame.

If your solar panels are dirty or covered in bird droppings, they won’t be able to absorb sunlight and will have reduced efficiency.

Generally cleaning solar panels isn’t necessary. In some cases rain is enough to wash off the dirt and debris from the panels, however, sometimes it is necessary to manually clean the panels. If you can see a lot of bird droppings on the panels even heavy rain won’t be able to clean the panels effectively. And if you live in an area prone to drought or an area with high amounts of dust or sand blowing around, regular cleaning is really important.
