We had a very unusual request a few years ago when we were removing paint overspray from many affected vehicles at a location at a California winery.  It came to our attention from the owner of a winery where the paint oversprayed vehicles were parked  that  the paint overspray had also affected 630 solar panels.

To solve this problem, we had our highly skilled technicians by hand,  using our unique rubber paint overspray eraser pads, that are similar to clay bars, remove all of the paint overspray from these solar panels that were roof mounted on  four buildings.  When cleaning these plexiglass solar panels, one needs to  be very careful placing as little pressure on their surfaces as possible, as they are very thin and can easily crack.  Also one needs  to take precautions not to haze and scratch these clear panels, as their voltage output could be greatly diminished.

When all the panels had been cleaned, the owner had the manufacture take a voltage meter and test the cleaned panels to make sure their voltage output  matched what it was when the panels were originally purchased.  All those involved in this project were totally amazed that  industrial  paint overspray could be removed from the 630 solar panels with no effect on the voltage output.

The cost to replace  these panels would have cost the insurance company  more than ten times what we charged  to clean them.

We have come to the realization that solar panels  covered with paint overspray or a film of any kind will not function properly. They will produce less voltage than they did when they were new; and to prove the point, all one needs to do is to test the voltage from each panel and compare the results with the manufacture’s specifications.

Paint overspray can be removed from almost any non-porous smooth surface without any resulting damage, if one is experienced and has the right technique.
