  • To remove layers of dust and dirt from the modules, simply wash the panel with tap water or DI water. If the module has thick dirt or grime and bird droppings, extensive scrubbing is required. We use profession grade, Mr. Long Arm Pro Curve Solar Panel Cleaning System Kit and Spot free deionizing water treatment system D.I.Rinse Pro 

  • A visual inspection of the modules can then be done to check for defects in the modules such as cracks, chips, de-lamination, fogged glazing, water leaks and discoloration. 

  • The condition of the array mounting frame should also be noted. Items to observe should include the array mounting bolts (e.g. bolt rusting) and checks to ensure that the frame and modules are firmly secured.
