Commercial Solar Panel Cleaning
Cleaning for large commercial and roof-mounted solar arrays — purified water, specialist cleaning equipment and planned maintenance, with drone cleaning for suitable larger or hard-to-reach roof arrays.
Commercial Solar Panels
Keep large arrays clean and performing
Dust, pollen, traffic film, lichen and especially bird contamination settle on solar panels. On large roof-mounted arrays that contamination builds up unevenly, can create shading on individual panels and is easy to miss from the ground.
We clean commercial arrays using purified water and specialist rotary-brush equipment, with no detergent residue left behind to attract more dirt. Bird fouling is treated carefully, and obvious damage, debris or nesting issues are photographed and reported. Many asset owners move onto a planned maintenance schedule once the first clean is complete.

Our approach
The right method for every surface
We never rely on a single technique. Each project is assessed and the safest, most effective method is chosen for the building and its surroundings.
Purified water
Deionised water dries residue-free for a streak-free finish.
Specialist equipment
Rotary-brush systems lift stubborn contamination and bird fouling without scratching.
Planned maintenance
Scheduled cleans keep performance consistent and simplify budgeting for asset owners.
Drone cleaning
Large or hard-to-access roof arrays cleaned from ground level where suitable and permitted.

Is drone cleaning right for this site?
Large commercial roof arrays can be one of the strongest applications for drone cleaning, reducing the need for people and equipment on the roof. Every project still starts with a remote survey, roof layout review and airspace assessment before we recommend it.
FAQs
Common questions
How often should commercial panels be cleaned?
It depends on location — arrays near farms, roads, trees or the coast often need cleaning more often. We can advise after the survey and set up a maintenance schedule.
How do you deal with bird contamination?
Bird fouling is softened and removed carefully with purified water and specialist brushes. Where birds are nesting under arrays, we can advise on proofing.
Will you need to go on the roof?
Not always. Depending on the site, arrays can be cleaned by drone or from safe access points. The site assessment confirms the safest approach.
