Question 2

How often should I clean solar panels in Illinois?

Twice a year: spring (April–May, after pollen season) and fall (October, before winter). Illinois humidity and pollen accelerate soiling compared to drier climates.

Yes. Annual contracts cover 2 cleanings per year starting at $300 for residential systems. We serve all of DuPage County.
