Solar panel cleaning robot

Type 1 / for roof-mounted panels

Autonomous cleaning robot for solar panels installed on roofs and rooftops. It restores power generation efficiency without using any water, a precious resource in desert regions.

Specialised in desert environments

Uses dry cleaning with brushes. It does not use any water, a precious resource in the desert, and provides the same high cleaning effect as when mopping with water. Consistent cleaning quality can be maintained, irrespective of the skill of the operator. Cleaning costs can be reduced by 80% compared to manual cleaning.

Autonomous running on the panel

The robot runs autonomously while recognising the edges of the panels. Thanks to the special mechanism we developed, the robot can move effortlessly over any gaps between panels.
Operation Pathway

(1) Place the robot in a corner of the PV array.
(2) The robot moves forward and sweeps the PV modules.
(3) When the robot reaches the end of the PV array, it changes direction and moves to the next row of PV modules. It repeats this movement.
(4) The robot signals the end of the cleaning. It arrives at the 'goal' point.

Can be carried by one person

The lightweight design can easily be carried by one person. Weighing only 28 kg, the cleaning robot has a small footprint that allows a single unit to clean panels from place to place, and can be expected to clean a wide area with minimal installation costs.

Rechargeable battery

The rechargeable battery is easily removable.
Charging time is approximately 5 hours for a full charge.
