Loughborough University researchers are to help develop cutting edge drone robotics for autonomous, fast, ultra-high-resolution solar plant inspections as part of a new collaborative project funded by Innovate UK.
Solar photovoltaic (PV) capacity is increasing, the fastest of all renewable energy sources, and countries around the world are racing to build large solar plants.
The most important challenge the industry faces today is to reduce costs and increase efficiency, which the project aims to solve through autonomous drones.
Above uses drones fitted with specialist cameras and sensors to collect data about solar PV modules and its cloud-based platform, SolarGain, identifies any defects. This solution is faster and more accurate than manual ground-based inspections using handheld equipment.
However, some defects that can reveal early systemic degenerative problems are only visible very close up.
Current drone technology is not yet accurate enough to fly safely autonomously significantly closer above the solar panels, and so labour-intensive manual inspections are still often needed.
By uniting experts in solar, robotics, artificial intelligence (AI), sensors and embedded systems, Follow PV aims to develop a spatially aware drone that can rapidly process and make in-flight corrections using artificial intelligence and sensing technology.
This will enable the drone to better capture the condition of PV modules in greater detail by flying closer to the panels’ surface.
Loughborough University’s Principal Investigator Dr Matthew Coombes, a lecturer in autonomous vehicles, is to lead on the aerial robotics control and navigation research.
His team will look at how AI processed sensor data can be used to control and guide drones accurately to allow close proximity solar panel survey flights.
Dr Coombes said: “Robotics and especially UAV’s have the ability to completely revolutionise how we conduct inspections and surveys across a number of sectors that traditionally rely on people painstakingly performing these manually.
“By performing inspections autonomously with UAV’s, they can be performed faster, safer, cheaper, and more accurately, while also being able to reach places normally inaccessible to humans. The solar industry would be an obvious benefactor from this technology.”
Will Hitchcock, CEO and Founder of Above, added: “It’s clear that robotics is playing an increasingly important role in the solar industry, and it’s exciting that Above is continuing to lead the agenda.”
Jinya Su, University of Essex’s Principal Investigator, said: “Solar industry would significantly benefit from these technologies considering its large scale and also the time/labour/cost involved in conventional human manual inspection.”
