Power Washing and Roof Cleaning Forum

This afternoon we cleaned approximately 600 solar panels on a strip mall in Voorhees Township, New Jersey. The weather is a little crazy this time of year in the NorthEast and it was a cloudy 44 degrees with rain off and on all afternoon. We typically use DI water and water-fed poles only to clean solar panels, but roughly 100 panels were surrounded by exhaust vents, from a restaurant below. These panels were caked in grease and needed an extra special touch. We used a Terra Wash, applied with our Gilmour Bleach Wash applicator, and let it sit for about five minutes. The we rinsed with DI water and then gave then a final scrub with DI and a water-fed pole. The grease melted right off and they looked new again. Attached are some pics. It worked so well, we went ahead and sprayed the other 500 panels also, before scrubbing. The owner of the strip mall was present and was so impressed, we signed a maintenance agreement for three cleanings a year. He also requested a proposal for the entire strip mall exterior and sidewalks, plus a quote for his house & roof. His house and roof are around 5500/SF.
