The BIG Question
Is solar panel cleaning really necessary?!
Short answer- yes. Now you may ask why is it necessary since the rain can clean the panels and remove dust and debris correct? Well does rain clean the windshield of your car? I wish it would, but every so often we have to go to the car wash. The same reasoning goes for the solar panels. Bird droppings, stuck leaves between the panels, dust and dirt are unfortunately inevitable. That is why once in a while you want your panels cleaned. This is not about the looks of the panels, but more about loss of efficiency. With time the layers of dust cover the photovoltaic cells that produce the electric field. This leads to loss of efficiency.
If you own solar panels you probably noticed this already, in the beginning you had high numbers and after a year or so (depending where you live) your efficiency goes down even though the weather is stabile. You paid a lot of money on the panels (or plan to), so you want them to work on 100%. We can help you achieve that goal.
Another question we often hear is “How often should I clean them?” The answer is it really depends on your location. We don’t push it since you as the home owner know your house better than we do. Usually once or twice a year is sufficient to keep them clean. Sometimes you want to wait even longer. It is really up to you and your preference.
Our service goes beyond just cleaning. When we are on the roof we inspect the panels, check for cracks or damage and even inspect the roof as good as possible. We take pictures of the damage and let you know, so that you can contact your solar installer to fix the issue.
