Rooftop Solar Cleaning
On a commercial or industrial rooftop, the real cost of cleaning is risk and access. Panels sit high, roofs are often low-tilt so dirt stays put, and every clean means sending people to height. The priority is simple: get the panels clean without putting a crew on the roof any more than necessary.
The challenge
Height & safety
Working at height is slow, costly and carries fall risk — especially on large factory and warehouse roofs.
Low-tilt soiling
Flat and low-slope C&I roofs don’t self-clean with rain, so dust and grime accumulate.
Access & obstacles
Rooftop arrays have edges, walkways and equipment a machine has to work around.
Recommended equipment

R1B Crawler Robot
Walks the array itself on anti-slip tracks, cleans wet or dry, and stops at edges with anti-drop detection. It keeps crews off the roof, cleans 1.5–2 MW of panels per day and handles module tilts up to 20°. A single-head R1A suits smaller roofs.

G4 Roller / G3 Double-Head
Long-reach brushes for the edges, odd shapes and rows the robot can’t reach. Pair the G3 double-head with the robot for full coverage.

The real cost of a rooftop isn’t the cleaning — it’s getting people up there
Height, access and low-tilt soiling are the crux, so coverage has to come with the fewest boots on the roof. A crawler robot walks the array itself while long-reach brushes finish the edges it can’t reach — one crew, far less time at height. And because the robot and the brushes are both ours, they’re specified to work as a single system on your roof, not bolted together from two suppliers.
Why a manufacturer matters here
We build the robot and the brushes, so they’re specified to work together on your roof — reach, power version and brush material matched to your layout and tilt. Local-standard plugs and voltages, English manuals and remote support come standard, and OEM/ODM is available for installers and O&M providers.
