No rails, no feet on your glass
PanelBot travels along your panel rows on its own, with no rails or tracks to fit. Nobody walks on your modules, so there's no risk of micro-cracks from foot traffic.
Automated solar cleaning · Built in Karachi
Dust takes 40%. We take it back.
PanelBot is a solar-powered robot that travels along your panel rows and leaves them clean. Our prototype uses just 15–20 litres of water per 100 metres, and our own engineers will look after it for as long as it runs.

The problem with the hose
Every day between cleans costs you power.
Karachi dust settles on your panels every day. A crew with hoses comes every few weeks, so for most of the month your plant runs below what you paid for.
One of Karachi's largest manufacturing plants told us they use 10,000 litres of water for a single cleaning of their solar array. Hard or salty water can also leave mineral spots that block light.
PanelBot changes the maths. Each clean uses so little water and no crew that you can clean as often as the dust demands.

Meet PanelBot R1
A machine built for one job.
Our working prototype is built. Book a meeting and we'll show you the robot, how it works, and how it would run on your site.

Working prototype
See PanelBot in person.
Meet our engineers, see the prototype and where we are in development, and ask anything about how it would work on your plant.
15–20 litres per 100 m
Designed so a measured spray and a 1,219 mm brush do the work of thousands of litres from a hose. Far less water to buy, store and pump.
Runs on the sun it cleans
An on-board solar supply powers the robot. No cables across your array and no load on your plant's output.
Clean as often as you need
When a clean costs a few litres instead of a crew-day, you stop rationing cleans and keep panels near peak output all month.
No crews on the roof
Rooftop cleaning means ladders, wet glass and live electrics. PanelBot takes people off the array and out of harm's way.
Built in Karachi, for Karachi
Designed against the dust, heat and humidity it will actually face. Engineers and spare parts are in the same city as your plant.

Side by side
The hose had a good run.
| Hose and crew | PanelBot | |
|---|---|---|
| Water per clean | About 10,000 L at one large Karachi plant | 15–20 L per 100 m of row (measured on our prototype) |
| How often | Every 2–4 weeks, because each visit is expensive | As often as the dust needs |
| People on the array | A crew on ladders, walking on modules | None during cleaning |
| Water quality | Large volumes of often hard water, which can leave spots | Small, controlled volume per pass |
| Power | Pumps and generators on site | Self-powered by solar |
| After the job | The crew leaves. You chase the next booking. | From full launch, our own service team: maintenance, repairs, spares |
Savings calculator
Output regained uses the same dust model as the chart above, kept conservative: 0.2% lost per dusty day, levelling off at 15%. 4.4 kWh per kW per day is typical for Karachi. Crew-days are workers × days, so 4 workers for 2 days is 8.

After-sales service · From full launch
Most companies sell you a machine. We stay.
Cleaning contractors leave when the job's done. Importers leave when the invoice clears. When PanelBot fully launches, we'll install it and keep it running for its whole life, with our own engineers.
Survey and design
We visit, measure your rows and plan how the robots will run.
Install and commission
We set up the robots, test every run and train your team.
Maintain
Scheduled visits keep brushes, drive, battery and water system in shape.
Repair
Our engineers fix faults with spare parts stocked in Karachi.
Grow with you
When your plant expands, we add robots.
These services begin when PanelBot fully launches. Today we're offering meetings and site surveys.
