Solar Panel Cleaner 32 Oz (Makes 128 G) - Super Concentrated Cleaning Solution for Glass, Metal, Wood & Plastic - Remove Oil, Fingerprint & Water Spots - Multipurpose Solar Panel Cleaning

For as little as I put in 4 gallons of water I was skeptical like crazy. Lo and behold that was the little train that could. Worked like a charm, couldn't ask for more, I haven't washed mine in over 7 years and they were horrible. Gonna take two times as I have Leyland Cypress trees that produce a lot of sap but it is cutting though it. It started raining or it would have got it on the first go around.

Works great though I did use more than what was recommended

This product cleans very well but I recommend a squeegee afterwards to dry your panels.

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.

After a unusual cold snap and heavy rains, my panels didn't seem to be getting the same output. After attaching a spray attachment, filled with this product I connected it to a water hose. After spraying, the panels, then leaving it run off I rinsed the panels. I once again have great output without paying someone to come clean them !

This stuff works great. A little goes a long way too. One photo is the panels with just a hose down and the other photo with like new panels is the work it does.

This product works as it should. It didn't seem to offer any special benefits over other similar products. No streaking, sprayed off nicely and cleaned well.

Made a cleaning solution per instructions. Used a telescoping pole and 18" window washing attachment purchased at Home Depot. Hosed off surface of solar panels. Dipped window washing cloth into washing solution. Wiped off solar panels, replenishing washing solution as required. Dirt was quickly removed. Rinsed off solar panels immediately after washing. Solar panels were clean and shinny even after drying.After a month the panels are clean and look much cleaner than the solar panels on nearby houses. Cannot document increase solar production after cleaning, maybe 10% but hard to document with kWh increased production due to cleaningHome Depot telescoping pole and window washing soft micro cloth attachment, good value, design, quality. Cleaning solution worked. $100 investment for every thing -hard to document payback period/ROI. Solar panels are definitely cleaner and the dirt is not returning to the surface after a month plus
