Desert Solar Farm Autonomous O&M System SandGrid Deploys in Sahara: Unmanned Operation in Extreme Environments
Abu Dhabi's Masdar and ABB deploy desert solar farm autonomous O&M system SandGrid in the Sahara Desert, with robotic cleaning, drone inspection and AI dispatch running fully unmanned, reducing O&M costs by 70%.
On December 20, 2029, Abu Dhabi clean energy company Masdar and ABB jointly announced that the desert solar farm autonomous O&M system SandGrid has been formally deployed in a 500MW photovoltaic plant in the Sahara Desert. The system comprises autonomous cleaning robots, drone inspection platforms and an AI dispatch center, achieving fully unmanned operation in extreme desert environments.
Deserts are ideal for solar power — abundant sunlight and low land costs. But sandstorms, extreme heat and aridity pose major O&M challenges. Traditional desert solar plants require significant labor for panel cleaning and equipment maintenance, with O&M costs exceeding 30% of total costs.
SandGrid's autonomous cleaning robots activate daily at dawn, using electrostatic adsorption and micro-water spray technology to clean sand from panels, using just 5% of water compared to traditional washing. Drone inspection platforms perform full-range infrared scanning daily, identifying hotspots, cracks and connection faults.
Masdar's operations director said SandGrid reduces labor needs from 25 people per 100MW to just 2 remote monitoring engineers, cutting O&M costs by 70%. This breakthrough brings desert solar LCOE below $0.01/kWh for the first time.
