Commercial Solar Panel Cleaning in Greater Victoria

We clean commercial solar panels the way the manufacturer requires: purified or deionized water, soft tools, and no abrasive pads or harsh chemicals, so the warranty stays intact. On a rooftop array with the right layout and clearance we deliver that clean by water-fed drone, which keeps our operators off the roof edge. Cost depends on array size, roof access, and how the panels are mounted.

How the work is done

Panels are cleaned with purified or deionized water and soft tools that will not scratch the glass or the anti-reflective coating. Abrasive pads, high heat, and household detergents are avoided because they can damage the surface and void the warranty. Where a rooftop array is open and clear, we run the water-fed drone over it so no one has to work at the roof edge. On tightly packed or obstructed arrays we tell you honestly and use the safe hands-on method instead.

The safety rules that govern it

Rooftop work at height is covered by WorkSafeBC fall-protection rules. Cleaning a suitable array by drone keeps operators off the roof edge, and the flight runs under Transport Canada RPAS rules.

What moves the price

Array size
The number of panels and total surface area.
Roof access and layout
Whether the array is open enough for a drone pass or needs a hands-on clean.
Mounting and tilt
Flush roof-mount, tilted racking, and ground-mount arrays clean differently.
Soiling and frequency
Pollen, salt air, and bird soiling raise the cleaning cadence.

Questions to ask before you hire

These arm you against a bad contractor. A company that answers them clearly, in writing, is easier to defend to your board.

01Does your cleaning method match our panel manufacturer’s warranty requirements?
02Do you use purified or deionized water and soft tools, with no abrasive pads?
03Is our array open enough to be cleaned by drone, or does it need a hands-on clean?
04How do you keep operators off the roof edge on our building?

Common questions

Can solar panels be cleaned safely without voiding the manufacturer’s warranty?

Yes, when the cleaning follows the panel maker’s guidance: purified or deionized water, soft tools, and no abrasive pads or harsh chemicals. We confirm our method against your specific panel warranty before we start. On a suitable rooftop array we can deliver that clean by drone so no one works at the roof edge.

How often should commercial solar panels be cleaned?

Most commercial arrays in Greater Victoria are cleaned once or twice a year. Panels near trees, on the waterfront, or under heavy bird traffic soil faster and may need cleaning more often to keep output up.
