According to the Solar Electric Power Association (SEPA) , PV electricity output will decline approximately 10% due to accumulation of dirt, dust, and other residues. Research cited by SEPA indicates that PV electricity generation will decline 15-30% in areas where bird droppings, urban pollution, sea air and from farming operations are common. Annual or bi-annual cleaning of panel surfaces eliminates these efficiency losses. At least once a year, your panels could benefit from a good cleaning, especially if you are in an area that has a lot of dust or windblown pollen. This stuff can get stuck to the panels fairly easily, and although a lot of it is washed away by rain that happens in a time of year you are not really thinking much about production. Therefore, at least once a year , you need to think about cleaning the panels. Every Six months is Recommended to maintain constantly high electricity generation (Spring/Autumn).
