Teexpert Solar Panel Cleaner (32oz Makes 150 Gallons), Ultra Concentrated Glass & Solar Panel Cleaning, Pro Streak-Free Ultra Quick Dry Remove Dirt, Dust, Droppings, Oils, Fingerprints & Water Spots

This product works! Left my panels shiny new. Sorry no before and after picture, but these panels were dirty and didn't look this good. I had tried just rinsing them with just water, that just left them dull. You don't have to use alot of the solution, it's ultra concentrated. Get the right tools for the job. I used a mirco-fiber type window scrubber with an 16ft extension pole and a bucket. I suggest an oblong type bucket, as the scrubber is 18 inches long. Be sure to turn of the electrical panel disconnect on the solar panels. I'm glad I brought two jugs.

This solar clean did an amazing job on our solar panels. The look like new. Loved the product.

It seems to work as advertised.

Excelente, producto. Muy eficiente para la limpieza de paneles solares.

I had to spray with water and scrub with a brush a few times after applying the solution to remove the film from the panels.

Did a very nice job on my solar panels. This with the kit and extension pole saved me $200 for the cleaning.

Very nice product!

Works fine washing
