Much like any other power generator, solar panels require maintenance and regular checks in order to continue operating at maximum efficiency. As solar panels are located outside, it is very easy for them to get dirty over a short period of time. This dirt could come from dust, rain, dirt, leaves, animal dropping to name a few.
Even if the layer of dirt seems insignificant, it can drastically affect the performance of your panels. You will also find that larger areas of dirt or obstructed sections will have a much larger effect on the efficiency of the panels.
How often should Solar Panel be cleaned?
Most owners won’t think to clean their solar panels until there is a problem, but professional solar panel companies would recommend that you have them cleaned and inspected every 6 months.
