What customers say about our solar panel cleaning
Real reviews left on our Google Business Profile by CSG customers.
“I had the best experience with Kevin and his crew. They came on time, we reviewed the scope of work, then they promptly got busy. The team brought their own equipment, were polite, and listened when I asked them to be mindful of our dogs and close the gate. They did 29 solar panels, removed mold and scum off a shingle roof, washed a flat roof, cleaned gutters and washed windows inside and out.”
“Bailey and Matt were polite, neat, and efficient workers! Results are fabulous: clean gutters, solar panels, and windows inside and out with great attention to detail and clean-up. Highly recommended!”

Good to know.
How often should I clean my solar panels?
Once or twice a year for most Sacramento-area homes. Systems near farmland, construction, or heavy tree cover may benefit from quarterly cleanings.
Can't rain clean them?
Rain rinses loose dust but leaves behind pollen, sap, droppings, and mineral spots that actually block sunlight more over time.
Will cleaning void my warranty?
No. Our pure-water and soft-brush method meets every major manufacturer's guidelines.
Do you go on the roof?
Yes — safely. We use fall-protection gear and roof-safe equipment. Whenever possible, we clean from water-fed poles on the ground.
