Some DIY projects are enjoyable, inexpensive, and yield similar quality results; however, solar panel cleaning is not one of them. Solar panels endure various types of environmental and weather conditions which leave layers of dirt, dust, residue, bird droppings, etc. Eventually, this creates a barrier that the sun’s rays cannot penetrate! Critics claim that debris causes a minimal decrease in power efficiency and could be sufficiently cleaned by wind and rain. However, some studies show that unclean solar panels can generate up to 10-25% less energy. Therefore, occasional solar panel cleaning is essential to preserving its energy production! And if your solar panels are not operating at their full potential, you are losing money on your investment!
