Why You Should Have Your Solar Panels Cleaned?

When you had your Solar Panels installed angles and mounting orientation are selected to maximize your Solar Panel's energy production. But solar has a dirty little secret...dirt! According to the National Renewable Energy Laboratory, when your panels are dirty yearly energy production can be reduced by up to 25%. Some studies even claim a reduction of up to 40% in high dust areas (like Utah). Google conducted an experiment at their 1.6 MW solar farm in Mountain View, California and found that cleaning was “the number one way to maximize the energy they produce.” [1]
