Built for O&M teams

We work to your site rules, safety plan and access windows. Scopes are set per site: full-array washes, targeted rows, or recurring visits tied to your production data.

NREL's O&M best-practice guide says cleaning can run on a defined interval or be condition based, and that a site-specific cost-benefit check should set the frequency. We help you put that into a schedule.

Robotic and traditional methods

All-electric robotic cleaners for long ground-mount and carport rows, and soft brushes with purified water for rooftops and tight layouts. No pressure washers, no harsh chemicals, in line with the NREL guide's warning against high-pressure water, abrasives and harsh detergents.

More than a wash

Every visit includes a visual check for broken glass, frame and mount damage, wiring and pest damage, with photos. Add weed abatement around ground-mount rows and bird mesh on rooftops and carports, so the site stays clean between visits.
