Who They're For and What They Solve
Solar panel cleaning is the careful removal of dust, pollen, bird droppings, and mineral film from the glass surface of photovoltaic modules. We use deionized water and soft brushes rather than detergents or pressure washers, because pure water lifts soiling and dries without leaving the mineral spots that ordinary tap water leaves behind.
Any solar owner watching their production numbers slide needs this service. Panels near agriculture, busy roads, construction, or heavy tree cover soil fastest. Pollen season coats glass in weeks. Homeowners who reviewed the maintenance guidance on the Mr. Local Services site typically schedule cleaning twice a year to stay ahead of buildup.
Soiling blocks sunlight, and blocked sunlight means lost kilowatt hours, commonly between five and twenty-five percent. Left alone, bird droppings shade individual cells and create hot spots that permanently degrade them. Baked-on minerals eventually etch the glass, and etching is not something any solar panel cleaning can reverse later.
Our Services
Our solar panel cleaning spans four approaches, matched to how your array is soiled and how it is mounted.
Our standard method. Water passes through a deionization filter that strips out every dissolved mineral, then flows through a soft brush head. It lifts dust and pollen and evaporates completely clean, so no spotting, no residue, and no chemicals touch your modules.
For arrays with heavier grime, we work panel by panel with soft-bristle brushes and gentle agitation. This handles film that pure water alone will not release. Frames and gaps get attention too, and nothing abrasive ever contacts the glass or the seals.
Droppings, tree sap, and hard water spots need targeted softening and patient lifting rather than force. We pre-soak, then remove deposits by hand. This clears the shaded cells that trigger hot spots, protecting the modules from lasting damage underneath.
Large rooftop arrays, carports, and ground-mount rows call for extended reach poles, higher water volume, and a row-by-row plan. We schedule around your operating hours and work through hundreds of modules in a single visit without interrupting production.
Not sure which approach your situation needs? We assess first and recommend only what’s necessary, no upsells.
Why Homeowners Choose Mr. Local Services
You get a firm per-panel rate before we schedule anything. No trip charges, no minimum surprises, no adjusted invoice after the work is finished.
We never use detergents, pressure washers, or tap water on solar panel cleaning. Pure water and soft brushes protect the anti-reflective coating that makes your modules efficient.
We carry $2M general liability and workers' compensation. Our cleaning follows manufacturer-approved procedures, so your module warranty stays intact.
Every solar panel cleaning ends with photos and a production comparison emailed to you. You see exactly what the cleaning recovered, not just a cleaner roof.
How It Works
Call 951-458-6466. We ask your panel count, mounting type, and last cleaning date, then quote a flat rate on that call.
We confirm a two-hour arrival window, usually within three business days. No waiting around, and no charge if we reschedule.
Technicians inspect for damage, choose the right method, then clean every module with deionized water. Most residential arrays take 60 to 90 minutes.
We walk the array, confirm streak-free glass, then email before-and-after photos plus your production comparison within 24 hours.
Pricing
Most residential solar panel cleaning runs $8 to $18 per panel, putting a typical 20-panel array between $160 and $360. Commercial and ground-mount pricing drops per panel as volume rises.
Four factors move that number: total panel count, roof pitch and accessibility, how heavily soiled the glass is, and mounting type. Steep roofs and hardened bird deposits take longer, so they price higher.
Every quote includes deionized water cleaning of all modules, frame wiping, a visual damage check, and your before-and-after production report. Call 951-458-6466 for a flat rate on your exact array.
Twice a year suits most arrays. Heavy pollen, dust, or bird activity pushes that to three or four times annually.
No. We use manufacturer-approved deionized water methods with no detergents or pressure, which is exactly what module warranties require.
Rain rinses loose dust but leaves mineral film, pollen bonding, and droppings behind. Those are the deposits that actually block production.
Recovery typically runs five to twenty percent depending on soiling. Your production report shows the exact before-and-after figures.
Tap water leaves mineral spotting and pressure washers damage seals. Roof work also carries fall risk that our insured technicians are trained for.
Yes. Many customers pair recurring cleaning with our solar panel maintenance program so inspections and washing happen on one visit.
Call 951-458-6466 with your panel count. You get a flat quote on the call and service within three business days.
Every week of buildup is output you paid for and never received. Book your solar panel cleaning now and see the difference on your next production report.
