Solar Panel Cleaner 1 Gallon (Makes 512 G) - Super Concentrated Cleaning Solution for Glass, Metal, Wood & Plastic - Remove Oil, Fingerprint & Water Spots - Multipurpose Solar Panel Cleaning

This is very concentrated cleaner so be careful not to get it in your eyes. Easy to use. Concentration is high so it will clean many panels per bottle. Durability is good. I added a few ounces to a 5 gallon bucket and filled with water. Just the mist coming up from the bucket irritated my eyes because it is so concentrated. I cleaned 24 solar panels with that single bucket. It rinses off quickly. Much better than using dish soap. The increase in power production is noticeable and profitable. The two pictures show the before and after production level of my solar panels. With this product, I don’t have to worry about any sticky residue that dish soap leaves behind, so I should continue to see positive results of the cleaning for many months. I rinse my solar panels six at a time first with the hose, then dunked a bar type cloth soft mop in the bucket and ran the cleaner over the panels and then rinse them. I continued until finished and they rinsed off streak, free, much quicker than dish soap

Very good purchase

Just trying it out for now. Seems to clean well. Waiting to see how well it handles water spots. I have 32 solar panels so I may need to use a bit more than others to get the results I'm looking for.

When I clean my panels with soap and water they usually look about the same, but seem to get dirty again fairly fast. I'm hoping the finish lasts longer and repels more dirt using this cleaner. It appears to be a bit shinier, but it's hard to tell in pictures. People don't realize how important it is to keep your panels clean. They collect dirt very easily being up on the roof, and the dirt acts like a filter and blocks some of the sunlight causing your panels to not absorb the energy you should be making.

Good

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'm so pleased with this product as it checked all the boxes for me. I wash my solar panels from the ground, so I wanted a no-scrub option. The run-off was going to go into my rain gutters, then into my garden so I did not want anything that would kill plants. Ladders are not my friend, so I needed the product to work by sprayer and power wash. I wanted it to rinse clean or leave a thin film to keep the dust off for a while longer. And I wanted the whole process to be as quick as possible as I must access my neighbor's back yard to reach my panels. Check and check. Highly recommend.

I received it on time, I haven't used it yet. The instructions are very clear, I believe it should clean my solar panels with no problems.
