Solar Farm Autonomous Management Robot Swarm SolarFarm Deployed in Saudi Arabia: Fully Unmanned from Cleaning to Fault Detection

ACWA Power announced on October 9 the deployment of the SolarFarm autonomous management robot swarm at the 2-gigawatt solar farm in Saudi Arabia's NEOM city. 200 specialized robots handle three core O&M tasks — solar panel cleaning, hot spot fault detection, and field weed removal — achieving the transition from manual operations to fully unmanned management.

Solar farms in desert environments face unique O&M challenges: dust coverage can reduce panel power generation efficiency by 3% to 5% daily, high temperatures accelerate equipment aging, and vegetation root systems can damage panel foundations. SolarFarm's cleaning robots operate automatically each night, using electrostatic dust removal technology to clear dust without touching the panel surface, boosting post-cleaning power generation efficiency by approximately 15%.

The NEOM solar farm is one of the world's largest single-site solar projects with a total investment of approximately $8 billion. SolarFarm's deployment has reduced O&M staffing requirements from 200 to 15 people (responsible only for remote monitoring and emergency response), cutting annual O&M costs from $120 million to $42 million.
