Solar panels in Merced, CA face a challenge most installers do not mention: San Joaquin Valley dust settles fast, builds steadily, and can make panels visibly dirty again within two months of a thorough cleaning. That is not a product failure or a cleaning shortcut. It is what agricultural dust does in this part of California.
Merced Window Cleaning offers solar panel cleaning for residential rooftops, commercial rooftops, and ground-mounted systems throughout the area. Pricing is per panel, every job includes before-and-after photos, and we do not clean solar farms.
Our pricing is straightforward. Single-story homes are cleaned at $7 per panel, and two-story homes are priced at $10 per panel to account for the added time and care required at height. All jobs are subject to a $249 minimum service charge. For a smaller system where the per-panel total falls well below that minimum, the most practical option is to pair the solar cleaning with exterior window cleaning. One trip handles both services and brings the total to a level that works more practically for the job. Final pricing also depends on roof layout and whether the property can be accessed safely, which we evaluate before confirming any appointment.
Recurring maintenance makes good practical sense in this climate. Customers who book biannual cleanings receive 10% off each visit, and those who commit to three cleanings per year receive 15% off. Given how quickly panels accumulate valley dust, staying on a schedule consistently outperforms waiting for heavy buildup between visits.
We clean residential rooftop panels using a water-fed pole connected to a three-stage filtration system running reverse osmosis (RO) water through nylon brushes, with no cleaning solutions at any stage. Depending on the roof layout, we access panels from the roof directly, from a ladder, or occasionally from the ground. We clean the top surface only and do not spray the underside where the wiring sits.
The same equipment and no-chemical process applies to commercial rooftop installations. Access setup may differ by property, but the method and standard stay consistent. This service covers rooftop panels at commercial buildings, not utility-scale fields.
Ground-mounted systems use the same water-fed pole and nylon brush process. Easier access does not mean a different approach. We work from the frames across each panel, scrub thoroughly, and rinse with filtered water.
We clean the top of each panel and avoid the underside where electrical connections are located. If we find damaged panels during a visit, including panels cracked by something like a golf ball near a golf course, we photograph them and notify you. We do not perform repairs. Some properties also cannot be safely serviced with the equipment we carry. A two-story home with a steep tile roof, dormers at the front, and no viable ladder position is the type of job we have been unable to service safely. We will tell you that directly when it applies.
Our three-stage filtration system produces reverse osmosis water delivered through a water-fed pole with nylon brushes. No cleaning solutions are used. If you have asked about DI (deionized) water or filtered water systems before calling us, this is what you were asking about.
Every solar cleaning job comes with before-and-after photos. Panels on a roof are not easy to check from the ground, and documentation matters. If we find damage during the visit, those photos get sent to you too.
We follow up on quote requests within a day, provide estimates over the phone, send automated appointment reminders, and text when we are on our way.
We do not force unsafe work to win a job. If your property layout makes a solar cleaning impossible to do safely without specialized equipment, we will say that directly and explain why. The example we have encountered is a steep two-story tile roof with dormers and no safe ladder placement. That kind of honest assessment is part of how we operate.
Merced Window Cleaning offers free estimates, is fully licensed and insured, and backs every job with a 100% satisfaction guarantee. We arrive with professional equipment and hold ourselves to a professional standard that carries through from the first call to the completed invoice. We have been operating in Merced since March 2022. Ricardo Daniel Hernandez founded the company after a career in agriculture and horticulture, which shaped a hands-on, methodical approach to exterior cleaning. Co-owner Mackenzie Hoyt, a UC Merced graduate and microbiologist, brought a precision-focused standard to how the company operates. We are a local team of 1 to 5 employees, and we are here for the long run.
Most jobs take between one and four hours depending on panel count and access. No cleaning solutions means no dwell time.
Call(209) 658-7454“> (209) 658-7454 or submit a request at mercedwindowclaning.com. We follow up within a day with a phone estimate, schedule your service appointment, send reminders, and text when we are on our way.
On arrival, we assess the property and choose the safest access route: rooftop, ladder, or ground. If conditions make the work unsafe, we stop and communicate that to you.
We connect the filtration system to the brush and pole and flush panels with reverse osmosis water to lift the surface dust layer before scrubbing begins.
We scrub from the frames across each panel surface three to four times, working top to bottom through the array.
Panels are rinsed generously with filtered water, then photographed for the before-and-after record. Damaged panels get flagged and documented. When the job is complete, we send the invoice. Payment is accepted by cash, check, or card, and card payments include a standard 3% card processing fee.
We do not offer a long-term cleanliness warranty for solar panels. In the Merced area, dust can return within two months. That is a local condition, not a cleaning shortfall, and before-and-after photos confirm the work was done. What we do stand behind is your satisfaction with the service itself. If something does not look right, call us and we will come back to address it. For customers committed to keeping panels clean over time, the biannual and three-times-per-year maintenance discounts make it easier to stay ahead of the buildup.

Call Merced Window Cleaning at (209) 658-7454, or submit a request online, and we will follow up within a day with a phone estimate. We serve Merced and surrounding areas within roughly 35 to 40 miles, and every solar cleaning job comes with before-and-after photos so you can verify the results even when the panels are on a rooftop that is hard to inspect from the ground. If valley dust conditions have you thinking about a recurring schedule, we will walk you through the biannual and three-times-per-year maintenance options when we talk. For smaller panel counts, pairing the cleaning with exterior window cleaning or roof cleaning makes the visit practical and worthwhile for everyone.
