Methods for solar panel cleaning.
Methods for solar panel cleaning.
  1.  It is advised to clean solar panels early in the morning or late in the evening, so that the temperature difference between the water used and the solar photovoltaic panels is as small as feasible. 
  2. Cleaning photovoltaic solar panels should not involve the use of any chemicals. 
  3. Do not use any sharp objects when cleaning solar panels of dirt that has adhered to them. 
  4. Do not clean the solar panels if they have cracks or if the system's couplings are damaged, as this could increase the risk of electric shocks.
