Australia’s national science agency, Commonwealth Scientific and Industrial Research Organisation (CSIRO) has completed trials of autonomous robots designed for solar farm maintenance.
CSIRO repurposed robots originally engineered for the harsh conditions of the mining industry to navigate thousands of kilometres of baked, uneven terrain.
The move aims to eliminate the need for maintenance workers to perform hazardous manual inspections on foot in some of the country’s most punishing environments.
These robots could also be revolutionary for solar farm maintenance.
Large-scale solar farms can produce upwards of 500 megawatts (MW) of electricity, enough to power 300,000 homes. However, keeping these massive arrays at peak performance requires constant monitoring of thousands of photovoltaic (PV) panels for faults, dust build-up, and electrical hotspots.
Equipped with a sophisticated suite of sensors, including LiDAR for 3D perception and thermal infrared cameras, the robots autonomously detect everything from loose bolts and bird droppings to hidden electrical failures.
CSIRO Senior Principal Research Scientist, Dr Peyman Moghadam, said the technology goes beyond simple data collection.
“We are building the foundations for intelligent solar operations, where data from robots, fixed sensors and field systems can be combined.
“This supports better proactive maintenance decisions and more resilient performance over time.”
Traditionally, these inspections are done by staff walking the vast sites, posing significant safety risks and high costs.
The robotic system not only lowers these overheads but also identifies issues early to extend the lifespan of the assets.
“If solar farms cost less to run and can be more consistent in their energy output, this increases the stability of the grid,” said CSIRO Senior Photovoltaic Scientist, Kenrick Anderson.
The agency emphasised that the tech won’t just replace manual labour; it will foster skilled regional jobs. Roles will shift from repetitive walking tasks to technical positions in robotics support and data analysis.
Ross Dungavell, Senior Robotics Engineer, CSIRO, said: ****“It’s good to fulfil a need in areas of the country where the labour is not attainable or reliably available.
“Often you cannot get someone to go out there under such harsh conditions, for extended periods of time.”
CSIRO is currently trialling the systems across several pilot sites and is looking to partner with industry leaders to roll out the technology nationally, supporting Australia’s transition to net zero.
