We Know Solar Systems, Not Just Cleaning

All Seasons Window Cleaning Inc. has served Grand Terrace homeowners for over 10 years. We’re NABCEP certified, which means we understand how solar systems work, not just how to clean them.

When we clean your panels, we’re also inspecting for loose connections, cracked panels, and other issues that could cost you thousands later. This isn’t just maintenance—it’s protecting your entire investment.

Grand Terrace’s unique desert climate requires specialized techniques. The dust from our surrounding hillsides and seasonal pollen creates challenges that regular cleaning companies don’t understand. We use equipment and methods designed specifically for our local conditions.

Solar Panel Cleaning Process Grand Terrace

Safe, Systematic, Results You Can See

We start by safely shutting down your system and inspecting for any visible damage or issues. No shortcuts, no risks to your equipment.

Our deionized water system removes all minerals that would leave spots or residue on your panels. This isn’t tap water—it’s purified water that rinses completely clean and actually attracts dirt and grime off your panels.

We clean each panel systematically using water-fed poles that let us work safely from ground level, even when roof temperatures exceed 140°F. This eliminates dangerous ladder work while ensuring thorough cleaning of every panel.

Finally, we clean around your panels, including mounting hardware and inverters, because desert dust affects more than just the glass. We restart your system and verify everything is working properly before we leave.
