A solar panel soft washing visit is a panel-safe clean of every module, a visual check of the array while the crew is on the roof, and a before-and-after record of the glass and of production. Knowing what happens in what order makes it easy to prepare and easy to tell afterward whether it worked.
AZ Solar Maintenance cleans panels across the East Valley, from Gilbert, Mesa, Chandler, and Queen Creek to the surrounding cities. Here is what to expect from the day you book to the next clear afternoon.
Before the visit
Getting the quote
You send your address. We count your panels from satellite imagery and quote a flat rate per visit, with no site visit needed to get a price. The quote is the number you pay.
A few things to mention
Some details change how the clean goes, so include them when you book:
- Sprinklers or irrigation that spray toward the house
- Palm trees, shade trees, or a flight path that drops debris or droppings on the roof
- Steep pitches, two-story access, or a roof you know is fragile
- Birds nesting under the panels
- A monitoring screenshot if output already looks low
The day before
- Turn off sprinklers that hit the roof, so the glass is not re-spotted right after the clean
- Plan for gates to be open and pets to be inside
- Save a screenshot of the last few days of production in your app
During the visit
1. Careful roof access. Most East Valley roofs are tile. Access is handled so the roofing surface underneath is not put at risk.
2. A safe clean of every panel. Dust film and hard-water spotting are addressed across the whole array with a panel-safe approach - controlled water and soft tools, not high pressure. Pressure washing panels the way you would wash concrete risks frames and seals.
3. A visual check while on the roof. Racking, connectors, and obvious wear get a look since the crew is already up there. Anything unusual gets noted so you know about it.
4. Before-and-after photos and a production check. You get photos of the clean and a look at production before and after, so the difference is on record instead of just an impression.
The crew is on your roof to clean panels. It is not a roof repair visit, so if a roofing issue turns up, you will hear about it and can call your roofer.
After the visit
Check on the next clear day
The fairest test is a clear, sunny day soon after the clean. Compare it to a similar clear day before the visit. Cloudy days, short fall days, and passing dust can all muddy the comparison. Our guide on how to tell if solar panel cleaning worked goes into the numbers.
If production does not improve
If the glass is clean and output still looks flat, the cause is probably not soiling. Dead strings, inverter faults, and wiring issues do not wash off. That is the point to move to a solar panel inspection or solar monitoring instead of booking another wash.
How long the clean lasts
That depends on your roof. Homes near open desert, active construction, irrigation overspray, or palm trees film over faster. For timing across the year, see how often to clean solar panels in Gilbert.
FAQ
Is soft washing safe for my panels?
Yes. It uses controlled water and soft tools rather than high pressure, which is the wrong tool for module glass and seals.
Do I need to be home?
Not necessarily. The crew needs roof access and a clear path from the yard. Mention gates and pets when you book.
Will you check my system while you are up there?
Yes. Every visit includes a visual check of racking and connectors and a before-and-after production check.
Should I clean first or inspect first?
If the glass is visibly filmed, clean first. If it looks clean and production is low, start with an inspection.
