The importance of cleaning solar panels!
Solar panels represent a substantial investment and you want to maximise your return on this investment.
Industry experts advise that output can drop by as much as 25-30% by not cleaning your solar panels. (This alone would pay for your system in 3-5 years.) Dust alone accounts for about a 7% drop.
Rain alone does not clean your solar panels, if this were the case we would just leave our cars in the rain to be cleaned.
Gutter-Vacs trained professionals can clean your solar panels for you and coupled with your regular gutter clean you will be surprised how cost efficient it can be.
