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

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.

I live where it gets 110 degrees plus in the summer , did not work as well as other product took heavy brushing and 300 psi spraying to clean my solar panels

Great to use in early morning to clean panels and don't turn white afterwards because of calcium or water deposits. I use a little than they say in instructions for 19 panels sunpower panels. Rinse first then use chemical Cleantite then rinse again and squeegee towel dry.

Solar Sheen works well as a cleaner and it is very effective in removing dirt and debris from my solar panels, however it didn’t seem to offer long-term protection against the elements because just a few weeks later, my solar panels got dirty again, but that’s OK because this is more of a cleaning solution then a protectant. I just thought it had a little bit more long-term coverage as well. Overall, it is a solid cleaning liquid and if that’s what you’re looking for this is gonna do the trick. Not cheap but they give you a very concentrated solution so it will last and save money over the long run. I have learned it’s more about cleaning frequently to keep solar panels shiny all season long.

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.

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.

Super concentrated, gets dust out quickly and cleans mold off the panels. Good product.

We followed the instructions for the "super concentrated". You have to use more than what they recommend on their instructions. The first couple panels came out ok. By the end, only water was coming out. We did everything it said to do, but quantity they recommend is too low. Double or Triple amount they recommended.
