Residential Solar Panel Cleaning in Chicagoland
Pane Pal Solar, warranty-safe, deionized water cleaning for homeowners across Cook, DuPage, Lake, Will, McHenry, and Kane counties.
The Problem: Dirty Panels Cost You Money
Illinois pollen season (April-May) and summer tree debris coat solar panels with a film that blocks sunlight. Dirty panels lose 7-15% efficiency, on a 20-panel system producing $1,500/year in energy, that is $105-$225 in lost production annually. One professional cleaning typically recovers most of that in the first month after cleaning.

What Happens on the Day
A typical residential cleaning takes about one to two hours for a 15-25 panel array. Larger systems, multiple roof planes, or three years of baked-on buildup take longer, because dried droppings have to be soaked and floated off rather than scrubbed.
You do not need to be home. We need access to the array and, ideally, an outside tap, though we carry our own water and a deionizer, so no tap is not a problem. If a gate needs unlocking or a dog is in the yard, tell us when you book.
You do not need to turn the system off. Cleaning the front glass does not require shutting down the inverter, and we are not opening anything electrical.
We work early or late, not on hot midday glass. Water hitting a sun-baked panel evaporates before it can rinse off, which leaves exactly the spotting we came to remove, and cold water on hot glass is a thermal-shock risk.
You get told what we found.The visual inspection is part of the visit, not an upsell. If we spot a cracked panel, a lifted clamp, chewed wiring, or a nest under the array, you hear about it, including when the fix is someone else’s job.
Expect the output bump within a day. Recovered production shows up in your monitoring app almost immediately. Compare the week after against the week before on similar weather.
Booking, Payment, and Scheduling
- Quotes are free. We quote from photos and a few questions for most residential jobs, or on site where access needs a look first.
- A 30% deposit confirms a residential booking once you approve the quote. That is what reserves the date. The balance is due after the work is finished, so you see the result before you pay the rest.
- Payment: secure card or bank link, Zelle, Venmo, check, or cash.
- Weather. We do not clean in rain, high wind, or on iced surfaces. If we have to move your date for weather, we reschedule at no charge, rescheduling is on us, not on you.
- Spring books out. Late April through May is the highest-demand window of the year across all six counties. If you want a May slot, book it well ahead, or put the visits on an annual contract and we schedule them for you.
- Satisfaction guarantee. If the result is not right, we come back and re-clean.
