Now onboarding early testers
Clean and inspect solar installations — autonomously
PanelWing pairs a ground robot with a tethered inspection drone to wash panels and capture thermal imagery in a single pass — turning routine maintenance into a continuous stream of performance data.

Ground robot and tethered drone, deployed at a utility-scale array
Solar assets lose performance quietly
Cleaning and inspection are treated as separate, occasional chores — which means most sites run underperforming and under-monitored between visits.
Output lost to soiling
Dust, pollen, and bird droppings can cut panel output well before it's visible in monthly generation reports.
Inspection doesn't scale
Walking arrays with a handheld thermal camera is slow, expensive, and easy to defer — especially across large sites.
Degradation caught after the fact
Cell defects and hot spots often surface only once output has already dropped or a panel has failed outright.
One system, one pass
A mobile ground robot carries water and compressed air; a tethered drone does the cleaning and the looking, at the same time, over the same panels.
- 01
Deploy
The ground robot navigates to the array carrying its own water and compressed-air supply — no fixed plumbing required.
- 02
Clean
A tethered drone sweeps each row, using water and air jets to clear dust, pollen, and debris from the panel surface.
- 03
Inspect
The same pass captures thermal imagery of every panel, catching hot spots and cell defects while the row is already covered.
- 04
Report
Imagery and readings stream back for review — no separate inspection visit needed.
From thermal data to a maintenance plan
Inspection is only useful if it changes what gets fixed and when. PanelWing turns each pass into a structured, comparable record.
Thermal capture
Every panel is imaged on every pass — not just when someone schedules a survey.
Defect detection
Hot spots, cracked cells, and string-level anomalies are flagged automatically against expected temperature profiles.
Actionable reporting
Findings are tied to a panel location and severity, not buried in a raw thermal image dump.
Maintenance scheduling
Recurring issues and trending degradation feed directly into what gets prioritized on the next site visit.
Built for two very different sites
Utility-scale parks and commercial rooftops don't fail the same way, and they don't get inspected the same way either.

Solar parks
Ground robots cover long, repetitive rows across large fenced sites, with tethered drones handling elevated or tracker-mounted arrays without needing individual flight permits per panel.
- Scheduled sweeps across MW-scale arrays
- Row-by-row thermal baselines over time
- Findings mapped to string and inverter groups

Rooftop installations
Compact deployment for flat and low-slope commercial roofs, where access is tighter and downtime for manual inspection is harder to schedule around building operations.
- No fixed cleaning infrastructure required
- Minimal disruption to building operations
- Reporting sized for a single-site facilities team
