Washing / cleaning
glass facade coatings
One of the major causes why the photovoltaic panels are losing efficiency is dirt. Thus, the washing/cleaning is absolutely necessary because the rains that normally clean the photovoltaic panels are not sufficient. Dust, pollution, litter of birds, insects, etc. cause a decrease in the yield of the photovoltaic panels, between 10% and 30% compared to those cleaned systematically with purified water which acts as an outstanding solvent on the dirt surfaces.
