Bare Ground Winter Bare Ground Solutions One Shot 1S-SPC Solar Panel Cleaner, 1 Gallon

This is a GREAT solar panel cleaner? I have used it twice to clean my panels and you just spray it on them and rinse. You don't even have to rinse good and it dries clear and shiny. I do scrub mine with a very soft panel brush but you don't have to do that either. It rained a little just after the last time I cleaned them and instead of spotting them it actually made them shiny clear again. I highly recommend this cleaner. Also, you can buy it by the gallon and just refill the dispenser bottle so don't dispose of that bottle once you use it all. I have 15 panels and it gives me 2 cleanings.

I have 12 solar panels in need of cleaning. I purchased this Solar Panel Cleaner Concentrate and being that this is the first time I am attempting to clean the panels I first followed the manufacturer's instructions that are printed on the bottle. They say to simply spray on the concentrate and let the panels dry to a nice clean shine. No, this left only a muddy mess on the panels. The method I used that gave me the best results are: 1. Using your garden hose spray the solar panels to remove most of the built up dust and dirt. 2. Spray on the Solar Panel Cleaner Concentrate using the included container attached to your garden hose. This will cover the panels with a rich foam. 3. Use a long handled window cleaning brush with a soft microfiber brush to gently scrub the foam covered dirt. 4. Lastly, use your garden hose again and rinse the panels with plain water. The end result was very clean solar panels, and with no water spots.

Easy way to clean panels. Has all the nice pressure to clean. Fist water the panels, then use product, clean with squeegee or clean cloth, and bamb, nice DIY project. Saves $. They charge me about $200 to $250 to clean, with this DIY, saves some cheese. Do recommend.

Works well on solar panels. Extremely slippery. Be very careful on roof when using.

Product did not clean panels at all, instead left a mess on them, Now I will have to clean them off with brush. Very disappointed, directions say to spray on & it will clean and protect. What a waste of money. I cleaned them before with just water and long handle brush & got much better results than this stuff. Claims to be streak less. no residue. That is BS! In fact It left my panels dirtier! I just hope that I can get this crap off my panels.

Well I was skeptical about the whole streak free formula and no need to scrub. Turns out I was correct. You will def need to squeegee and use a dirt free soft nylon brush. Ok so here are the steps for this product which worked best for me. 1. Use water side of spray bottle and remove as much dirt as possible. 2. Use Mix side of spray bottle and cover panel evenly but don't over soap. A little bit goes a long way. 3. Use clean soft nylon brush on entire panel. Using a circle motion . Don't over clean one pass is enough you don't wanna scratch your panels so no force is needed. 4. Use water side of spray bottle and spray off soap and dirt. Just enough to get the soap bubbles off. Don't spray it to death or the spot free rinse stuff will def not work. I def suggest a squeegee for the next step. 5. Squeegee off the panel and let it dry. Fyi when I finally built up a system I was able to do 2 or 3 panels very fast. I actually went back a did a few panels again as mine were very dirty. We have had a bunch of fires were I live. On the whole I think this product is very good but the instructions were not very in depth. So for that I'm giving it 3 stars. Also because it says that you can just leave on the product and you will get a streak free no spots shine. I tested that one and soap spots were everywhere. So def don't just spray it on and forget it. Also buy a decent squeegee it will save you headaches and the job will go faster. I would buy this product but I would hope the maker would take my suggestions into consideration so people don't just think they can spray it on and walk away.

My solar panels looked clean. The solution did not smear. I plan to buy again.

Easy clean
