Fully Self-Powered
An onboard solar panel and built-in 48V/15Ah battery mean E2 Pro never needs a power hookup, even on remote, off-grid sites.
Off-Grid Solar Cleaning
E2 Pro
E2 Pro is a self-powered cleaning robot built for large-scale and non-standard ground-mount arrays. An onboard solar panel and built-in battery mean it never needs a site power connection, even on the most remote installations.
Dual-axis walking correction keeps it centered as it moves across slopes up to 45° and adapts to multi-angled layouts, covering up to 1.8 km in a single pass while its soft PBT brushes lift dust at up to 99% efficiency without marking the glass.
- Fully self-powered: onboard solar + built-in battery
- Up to 1.8 km covered in a single pass
- Handles slopes up to 45°, even on multi-angled arrays
- 99% cleaning efficiency, dry or light-water mode
Capabilities
Built for arrays other robots can't reach
E2 Pro trades fixed infrastructure for onboard power and adaptive walking, purpose-built to clean large-scale, off-grid ground-mount arrays.
Adapts to Any Array Layout
Dual-axis walking correction adjusts to different panel types, postures, and positions, keeping the robot centered across non-standard and multi-angled installations.
Built for Large-Scale Coverage
Covers up to 1.8 km in a single one-way run, clearing continuous rows of ground-mount solar without repositioning.
Dry-Clean Technology
Soft PBT brushes lift dust at up to 99% efficiency without scratching the glass, running dry or with a light water-assist for heavier buildup.
Real-Time Safety Sensing
Edge-detection and terrain sensors continuously scan the surface ahead, automatically triggering an emergency stop if they sense a drop-off, obstacle, or irregular terrain.
Lightweight Aluminum Build
An aluminum alloy chassis keeps weight and panel stress to a minimum, while sealed, corrosion-resistant construction holds up in coastal and desert conditions alike.
