Solar Panel Cleaning
How are solar panels cleaned?
Solar panels are rinsed at low pressure with soft tools, following the panel manufacturer's cleaning guidance. No high-pressure wand is used on the glass. Dust film, bird droppings, pollen, ash and debris along the frames are removed from rooftop, ground-mount and patio-cover arrays.
Long dry stretches in Los Angeles let dust, pollen and bird droppings build up on rooftop panels. Solar panels are not cleaned with pressure — they need gentle, low-pressure rinsing and soft methods that respect the glass and frame.
Panels are rinsed at low pressure with soft tools and appropriate water, following the panel manufacturer's cleaning guidance. No high-pressure wand is used on panel glass.
Pressure washing vs. soft washing
Pressure can damage panel seals and coatings. Solar cleaning is a low-pressure, soft-tool process.

What solar panel cleaning removes
Cleaning clears the fine dust film that accumulates on panels during long dry stretches, along with bird droppings, pollen, and the light ash residue that can settle after nearby fires or heavy wind events. Debris collecting along panel frames and edges, where dust and leaves tend to gather and sit undisturbed, is cleared as part of the same process. Even a thin, even layer of dust that isn't obviously visible from the ground can accumulate across an entire array over time.
What cleaning can't fix
Cleaning addresses what's sitting on top of the panel surface — it won't fix reduced output caused by panel aging, wiring issues, or inverter problems, which are electrical matters outside the scope of a cleaning service. Scratched or etched glass from improper past cleaning attempts won't be corrected by a proper gentle clean; that damage is already in the glass. Panels that are already failing or underperforming for reasons unrelated to surface dirt will show the same performance after cleaning as before. Micro-cracks in panel glass, if present, aren't caused or fixed by cleaning, and any such damage is simply noted for the homeowner to review with their installer.
How we do it, and why this method
Solar panels are never cleaned with high pressure, because pressure can damage panel seals, delaminate coatings, or force water into electrical connections that are meant to stay sealed. Instead, panels are rinsed at low pressure using soft tools designed not to scratch the glass surface, following the cleaning guidance set by the panel manufacturer.
Because panels are typically mounted on rooftops or elevated structures, access and safety planning happen before any cleaning starts, and the approach stays consistent whether the array is roof-mounted, ground-mounted, or built into a patio cover. No abrasive pads or high-pressure wands touch the glass at any point in the process. Working carefully around frame edges and junction boxes also keeps water away from connection points that aren't designed to get wet during routine maintenance.
What affects the cost
- The number of panels and total array size affects time on site.
- Roof pitch and height influence access requirements and how the work is approached.
- Ground-mount and patio-cover arrays are generally more straightforward to access than steep rooftop installations.
- Heavier buildup, like caked-on bird droppings, can need more time than a light dust layer.
- Scheduling panel cleaning alongside roof cleaning can be more efficient than two separate visits.
- Panel manufacturer guidelines sometimes specify particular handling that shapes the cleaning approach.

When to schedule
Panels in areas that go long stretches without rain tend to build up dust steadily, so cleaning on a schedule rather than waiting for a visible problem helps maintain consistent output. Right before or after a dry season is a reasonable time to plan a cleaning, since that's when dust accumulation is typically at its highest. There's no need to wait for an obvious performance drop — a light, regular cleaning schedule keeps panels from reaching heavy buildup in the first place.
What to expect on the day
The crew reviews the array layout, roof access points, and any manufacturer-specific guidance before starting. No preparation is typically needed on the homeowner's part beyond ensuring clear access to the roof or array location. Panels are rinsed at low pressure with soft tools, working across the array methodically, and no electrical components are handled or disconnected during the process. Panels will be visibly wet immediately after and dry quickly given their sun exposure.
Questions
Solar Panel Cleaning FAQ
Do you use pressure on solar panels?
No. Panels are cleaned with low-pressure rinsing and soft tools.
Can panels be cleaned with the roof?
Yes, solar cleaning is often scheduled alongside roof cleaning. Tell us about both in your quote request.
Will cleaning void my solar panel warranty?
Cleaning performed with low-pressure, manufacturer-approved methods is generally consistent with standard maintenance, but check your specific warranty terms if concerned.
How much does dust actually affect panel output?
A dust layer can reduce output, with the exact impact depending on how much buildup has accumulated and over what period.
Can you clean panels on a steep roof?
Access and safety are assessed per property. Steep roofs may require different handling than low-slope installations.
Do you clean the underside or back of panels?
No, cleaning addresses the exposed glass surface that collects dust and debris, not internal or rear components.
