Solar panels are usually the last items on a cleaning list, but solar panel cleaning is actually quite important. Over time, birds leave droppings and debris on them, plus birds can sometimes nest under the panels, which causes feathers and additional items to collect around and on top of the panels. This, in addition to the build-up of dust and dirt, will lower the productivity of the panels. Research has shown that the longer you go without solar panel cleaning, the less sunlight is getting through to save you on energy costs.
Additionally, pollen and leaves can stick to the panels. These do not dissolve or get blown off, and often they do not wash off with rain, either. Rainwater is not the best solution for solar panel cleaning. Rain carries dust and other small debris that can build up, leaving a film on the panels that negatively affects their functionality. You should also note that not only is rainwater not adequate for solar panel cleaning, but it can also pool on the panels, or if there is already dust build-up, it can create mud that will streak the panels.
Solar panel cleaning is often required for the warranty of your solar panels. To utilize the warranty, should anything go wrong, you might have to prove that the panels have been regularly cleaned to keep them active and free of damage. It is recommended that you clean your solar panels 1-2 times a year.
