GEKKO Solar in Desert Sand of Doha, Qatar

GEKKO Solar proves its efficiency in the challenging environment of the Middle East region

The Middle East region is predestinated for solar power plants. On the other hand it is a challenging environment when it comes to the permanent appearance of sand/dust in the air, combined with very little rain fall. This constellation leads to a fast covering of the panels and therefore negatively affects the efficiency of the plant.

In tests done in Saudi Arabia, photovoltaic solar cells exposed for six months to those conditions lost a massive 40% of their efficiency due to accumulated dust. Other researchers found that even a fine layer of dust can be enough to cause efficiency to drop by 10%.

SERBOT AG was invited to Doha, Qatar, to prove the efficiency and effectiveness of the solar panel cleaning robot GEKKO Solar. The plant, installed on the roof top of a large building, is the first of its kind in the region. It includes 3,500 square meters of solar panels which cover up to 12.5% of the centre’s energy needs.

To ensure this energy delivery over time, regular cleaning is required. The today’s method is manual cleaning with brushes (dry). This is very time consuming and the cleaning effect is not satisfactory.

GEKKO Solar optimizes the cleaning of solar panels in many ways:

  • Effectiveness: A rotating soft brush in combination with deionised water ensures a proper and stripe-free cleaning.
  • Efficiency: Cleaning capacity reaches up to 400 square meters per hour.
  • Easy operation: Only one operator is required to control the robot via wireless remote control unit.

The attendees of the product demonstration were impressed by the performance and ease of use of the GEKKO Solar.

These panels deliver only a part of their power – after a short time!

Before: Solar panels, completely covered with hardly removable dust

Afterwards: GEKKO's cleaning image is convincing
