Glass Gleam Solar - Solar Panel Cleaner - Highly Concentrated - 1 Gallon Makes 500 Gallons of RTU Product (1 Quart)

This did an amazing job on our solar panels. You use very little so it will last forever. Cost was very low.

Works great

works great

Did a test on one panel and it seemed to work ok. I pour some into the foam bottle on our pressure washer and applied it to one panel. I let it soak about 5-mins and then rinse and it seemed to work. Our panels were not that dirty as I had just cleaned them a month before so time will tell. I'm planning to wash them again in early July and will update my review as needed.

So, I use a 2 gallon (garden type) pump up sprayer to apply this product to my solar panels, its super concentrated, 15ml to two gallons of water, I got my 15ml measurement from a cough syrup cup. I just spray it onto my panels, leave it for 2 or 3 minutes, then rinse it off with a water nose……my panels are on the ground. It’s easy to use, more stubborn spots might need to be brushed off….this quart of cleaner, might outlast my solar panels…lol

Had solar panels for 4 years without ever cleaning them. Recently noticed my production was low, even on cloudless days. Bought this solution and a motorized solar panel cleaning brush on a 20’ pole and it worked great! 35% increase in production form the day prior with the same weather. Will start doing this annually. I mixed the solution into a car wash foam gun and it worked great.

My panels are 2 years old and never cleaned. The dirt was caked on. This product with a good soft bristle brush will make the panels look new again. This can save you $250+ (so cal prices). Product was applied with a pressure washer

Used this to clean my solar panels, it failed to remove all of the dirt, left a residue on panels. I tried twice and used a squeegee, still left a residue. Will try something to see if it was a one off.
