Why do I need to clean my solar panels?
Your purchase of solar panels represents a significant investment. Allowing solar panels to become dirty due to airborne particles, bird droppings, and tree leaves can greatly diminish your solar power output. In other words, you are not getting the production you paid to get. If solar panels are never cleaned you not only lose a significant amount of power, you also risk losing the panels.
How much electricity do dirty solar panels lose?
While many factors impact solar power production in solar panels, experts agree that you will lose power. That loss may range as high as 25% in some areas according to the National Renewable Energy laboratory. Individual dealers have reported losses as high as 30% for some customers who failed to ever clean their panels.
As you can see by the picture it is suprising how dirty they can get. And because they are usually in an unaccessible location it is hard to tell if they are clean.
Won't the rain wash the dirt off the panels?
During the summer there may be long periods where it does not rain and the summer is when photovoltaics produce the most electricity. When it does rain some of the loose dirt is removed but more is deposited in its place. Some types of soiling such as that from birds will remain for many weeks and even months if they are not cleaned.
How often should I clean my solar panels?
In the UK this is something that we do not have much experience or knowledge with. Luckily solar panel cleaning services in other countries have been established for many years and many recommend getting them cleaned twice a year. Some suggest you get them cleaned every couple of months.
For the best results the first clean should be at the start of spring as the days lengthen and the amount of sun reaching the panels increases. Later in the summer they should be cleaned again. For the UK climate this seems to be the best solution.
