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

This product worked for me. I've had my panels for over 3 years and never cleaned them so I had to pass over each of the panels two or three times but they ended up super clean and working great! Great value. Would recommend.

I used this item to clean my solar panels and it seemed to work very well. My panels are clean and I could see a very good increase in the power output from my solar panels.

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.

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

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

I had solar panels installed about 3 years ago and have never cleaned them so they had caked on dirt and bird poop and this cleaner cleaned it off really good. Pairing the Glass Gleam cleaner with the Kamirola High Pressure 8 in 1 Car Wash Brush Foam Gun and a telescoping pole scrubber it was super easy to clean the panels while standing on a ladder. I used about 3/4 of the cleaner and was able to clean 32 panels doing 2 cleanings. I first ran water over the panels then soaped the panels good and scrubbed away. I made sure to keep the panels wet and soapy before scrubbing to avoid any scratching. I ran the soap and rinse twice to make sure I got everything off. Worked like a charm and I'm going to stock up on this cleaner for next year.

works great
