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 !

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

I'm 77 years old and not physically capable of climbing up on the roof. I used the product as directed, but I still had to scrub my solar panels. The spray and rinse only removed the top layer of loose dust. I had to respray, scrub and rinse. Even so, there's a thin brown layer of baked on dust on the panels. I achieved the same level of dust removal with Windex Window Cleaner on the previous cleaning.

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.

Just used it back 2 weekends on my home solar panels and then last weekend on my small set on my yard shed. The home has 49 panels and can be challenging, but the liquid cleaners works great. Two person job, one on the ground filling the hose dispenser and the other on the ladder doing the work. Husband and wife team. Guess who is on the ladder. Out of curiosity I measure the voltage on the shed panels before and after cleaning. Before (they were as dirty as the house) 12.4 volts being generated. Ok, batteries charging, but after cleaning 13.8 volts a ~10% improvement. I noticed my home panels were having trouble keeping up with our electric pool heater. After cleaning, I was still generating a little power with the pool heater on. So really like the product but only saw these results with this product.

I've had my solar panels for about 5 years now and never thought about having to clean them. So you can imagine what they looked like when I got on my roof to clean them. Years of pollen and dust just caked on there. Luckily, Solar Sheen worked to perfection and made the job easy. They are so clean now that I'd be willing to eat off of them! I even decided to clean my reading glasses with it and now I feel like I am reading in high definition! 10/10. I recommend to anyone with solar panels or if you have any glass or plastic with some pesky dirt that you need to remove.
