Pollen, dust and bird droppings can rob your panels of up to 30% of their sunlight. We clean them gently, with the right tools — no scratches, no harsh chemicals.
You invested in solar to produce power — but panels can’t convert sunlight they can’t see. In our region, spring pollen alone can visibly film an array, and every layer of dust, ash and bird droppings cuts production. Studies show soiled panels can lose up to 30% of their sunlight capture; regular cleaning is the cheapest efficiency upgrade you can buy.
Rain doesn’t fix it, either — it leaves mineral spots and moves grime to the panel edges where it hardens. We clean arrays the way manufacturers recommend: soft brushes, purified water, and zero high pressure, protecting both the glass and your warranty.
Very few cleaning companies in the Panhandle touch solar. It’s a specialty of ours: we understand the racking, the wiring and the glass coatings, and we treat all of it with the same care we bring to soft wash roof cleaning. If your roof needs attention too, we can often clean both in one visit.

It varies with soiling, but studies show heavily soiled panels can lose up to 30% of the sunlight reaching their cells. Even a light pollen film measurably cuts output.
No — rain deposits airborne dust and leaves mineral spots as it dries, and it doesn’t touch bird droppings or edge grime. Manual cleaning with purified water is the only method that restores full clarity.
Yes. We use soft brushes and purified water — no pressure washers, no abrasives, no harsh detergents — which is exactly what panel manufacturers specify.
Once or twice a year is typical here: after spring pollen season, and optionally in fall. Arrays near trees or farms may benefit from more frequent service.
“Nando’s exterior cleaning service was so awesome. The guys responded quickly, did a good thorough cleaning of my vestibule which was turning dark and dingy but now it’s white and clean again. I am thrilled with the phenomenal job they did and for very little cost. I will definitely have them come back. Thank you all!”
Danielle Johnson“I’ve used Nando’s three times now and am very pleased. They’ve cleaned my gutters twice and cleaned my roof when I had moss growing due to shade and wetness. Everything has been wonderful. Very professional and on time. They will work with your schedule. Won’t hire anyone else.”
Rhonda Lovato“This is the second time I’ve hired Nando’s, to pressure wash the entire exterior of a home. Last time I had them pressure wash a vinyl fence and concrete pathways. They are responsive, professional, reliable and do great work. Nando communicated with me throughout the cleaning process with texts and photos of the progress since I couldn’t be on the property at the time. They are a trustworthy and competent company, and I would recommend them to anyone.”
