Solar Panel Cleaner Solar Sheen (Makes 128 Gallons) - Super Concentrated Glass & Solar Panel Cleaning, Remove Oils, Fingerprints & Water Spots - (32 oz)

Great solution, and strong concentrate. As described. Cleaned solar panels very well and streak free. Worth it.

Was surprised by how much this white calcium like deposit it removed from my panels.

Product worked fantastic. I wish I would have taken a before picture. My solar panels were covered in caked on dirt. I had not cleaned them in almost 9 months. I used a deionized water filter for water (the no rinse style of car wash filter system) and twice the recommended amount of cleaner because i found that worked best for me. My process was, rinse the panels, wash with an extension pole and microfiber sponge attachment, rinse again, wash again, followed by a final rinse. This is mostly because of how dirty my panels were. I washed half a panel before I dunked the sponge into the cleaning water to get the dirt out of the sponge. I went through 4x 4ish gallons of water with 2oz of product mixed into each one to do 18x 430 watt panels. I did not squeegee the water off the panels after the final rinse, i just let it air dry. Very happy with this product and will buy again.

Bottle arrived with the cap secured with tape. Used the liquid with a spray nozzle though probably not as intended to clean roof-mounted solar panels since I did not want to use a brush at ground-level. The dilution mix was set to the highest concentration. Sprayed the panels with clean water to remove the top residue. Sprayed the dilution mix on the panels and allowed it to sit on the panels for 10 minutes. Re-sprayed as needed to keep the panels wet. Washdown with clean water. Did 3 cleaning cycles. Afterwards, most of the opaque film was removed. The remaining film was expected to be a mix of pollen and dirt since no brush was used. The most apparent change afterwards was the film build-up was much slower. Using a brush is necessary to remove pollen or similar. I also used the cleaner at full strength to remove the haze on the inside of a car windshield. The cleaner did remove the haze much easier with low odor compared to a standard window cleaner. Highly recommend for cleaning panels, so professional cleaning is less frequent, and to clean the inside of car windows/windshield.

I clean my panels once a week normally just rinsing them off with , but this product actually removes a lot of the water spots and almost makes them look shiny. I suggest spraying on then rubbing with a brush just a little bit and then rinsing off. The panels in the photo are not wet. It’s actually been a week since I’ve cleaned them. I will use this product from now on it does a good job.

Works great!

This product has little effect on hard water deposits on the solar panels of the pathway lights from the sprinkler system. The product description seems to indicate that it would work, perhaps with multiple applications at full strength. Thus far, no luck.

I was a little skeptical about whether or not this cleaning solution would work well on my solar panels that had not been cleaned in almost 10 years. I was even more skeptical when I saw how little of the solution you needed (about 1/2 tablespoon per gallon). I ended up cleaning the panels as directed - hosing down, spraying the solution on, cleaning with a pole brush, then rinsing and squeegeeing the panels. I let them dry and when I came back up I was surprised at how clean they looked. I missed a few really dirty spots, but overall I’m impressed with how well they came out for as dirty as they were.
