WASCAL donates cleaning robot to Zagtouli solar power plant in Burkina Faso

This robot is designed for autonomous or semi-autonomous cleaning of solar panels, boasting a cleaning capacity of 2000 m² per hour, equivalent to over 4 MW per day. Its 2.45-meter rotating brushes and ability to operate in demanding environmental conditions effectively remove accumulated dust, thereby restoring and maintaining optimal energy production. The robot can operate with or without water, which is beneficial in arid regions with limited water resources, and has an 8-hour battery life.

Wendpanga Roger Ouédraogo, director of transport and energy movements at SONABEL, noted that the robot is economical as it does not require energy to function, and its total cost is estimated at 50 million FCFA. Alidou Koutou, director general of energy, received the equipment, emphasizing that cleanliness is crucial for the profitability of solar power plants and that the robot will help optimize production by improving efficiency. He also urged responsible use of the equipment to ensure its durability.

This donation is WASCAL's second to the Zagtouli plant, following a tractor with a cleaning system and surveillance cameras in 2025. It is part of the PV2H project, implemented by WASCAL, which aims to sustainably improve the performance of photovoltaic solar power plants in West Africa.
