Waterless · Battery-free · Autonomous

Dust costs you power. We take it back.

A robot cleans every row, every morning — powered by the panels it cleans. No water, no batteries, no crews.

Estimate: up to ~20% output lost to dust between monthly washes; ~4 peak sun hours a day.

Sound familiar?

Dirty panels quietly drain your revenue.

If you run a solar plant or factory roof, you've probably hit at least one of these.

"Output keeps sliding between washes."

Panels cleaned once a month make up to ~20% less than clean ones. Dust starts costing you the day after the crew leaves.

→ Cleaned every morning, automatically.

"Washing crews are expensive and hard to book."

Labour costs climb every season, bookings slip, and crews still miss the rows that are hard to reach.

→ 2–3 people watch a dashboard instead.

"We don't have water to spare."

On desert and Gobi sites, every tonne of wash water has to be trucked in — and it's gone after one clean.

→ Fully dry. Zero water.

"Our robots died in winter."

Battery robots stall in the cold, lose capacity every year and need new packs.

→ No battery. Runs from −40 °C.

"Birds keep leaving hot spots."

Droppings shade cells, create hot spots, age modules early and raise fire risk.

→ Blade lifts droppings; cable deters birds.

"I worry about people on the roof."

Wet, live panels at height are a safety incident waiting to happen — and heavy trucks crack modules.

→ Nobody on the array. Light load on glass.
