Jaguar Land Rover’s Rooftop Solar: Inside the UK’s Largest Automotive Solar Program
Jaguar Land Rover (JLR) has spent the past decade turning its UK factory roofs into one of the country’s biggest corporate solar programs. What started as a single standout installation in 2014 has grown into a multi-site renewable energy strategy tied directly to the automaker’s net-zero targets.
How it started: the Wolverhampton Engine Manufacturing Centre
In April 2014, Jaguar Land Rover completed installation of what was then the UK’s largest rooftop solar panel array at its new Engine Manufacturing Centre at i54 South Staffordshire, near Wolverhampton. More than 21,000 photovoltaic panels, with a capacity of 5.8MW, went onto the roof, with plans to expand to over 6.3MW by the end of that year. The system, spread across 35,000 square meters of roof space, was installed by Kingspan Energy in just 11 weeks.
The array was projected to generate more than 30% of the Engine Manufacturing Centre’s energy needs, equivalent to the power used by over 1,600 homes, while cutting the plant’s CO₂ footprint by more than 2,400 tonnes a year. The facility itself represented a serious commitment: the site involved an investment of more than £500 million and was expected to create almost 1,400 jobs once fully operational.
Expanding the program: Gaydon and China
The Wolverhampton project wasn’t a one-off. JLR later opened a 26-hectare ground-mounted solar farm, roughly the size of 36 football pitches, to power its Gaydon, Warwickshire, headquarters, supplying 31% of that site’s energy. The company paired the solar build with environmental work on-site, planting native wildflowers beneath and between the panels and restoring hedgerows for birds and pollinators.
JLR has also installed rooftop solar at a joint-venture facility in China, generating roughly half of that site’s energy.
The 2024 push toward 25%+ renewable electricity
In March 2024, JLR announced plans to generate more than a quarter of its UK electricity from renewable projects, mostly solar, across three sites: its Halewood plant in Merseyside, the Electric Propulsion Manufacturing Centre (EPMC) in Wolverhampton, and its Gaydon headquarters, aiming for almost 120MW of renewable capacity at peak.
The plan mixes rooftop panels, ground-mounted arrays, and solar carports to power manufacturing processes and EV charging, aiming to lift solar’s share of self-generated energy by 16%. All three sites were expected to be operational by the end of 2026, with an 18.2MW ground-mounted array already approved for Gaydon. The broader goal is to reach 36.4% self-generated energy across JLR’s global operations by 2030.
As JLR’s sustainability lead put it at the time, the projects are meant to diversify the company’s energy mix and cut both grid dependence and energy costs.
The Wolverhampton expansion: the largest automotive rooftop array in the UK
The Wolverhampton site later grew further, with an 18,000-panel, 10.7 MW system expected to generate around 9,512 MWh of electricity a year, enough to power over 3,500 homes, making it the largest automotive manufacturing rooftop solar array in the UK. Combined with existing capacity, the site’s solar output is set to meet nearly 40% of its energy needs, supporting production of electric drive units and batteries for JLR’s newer vehicles.
Why it matters
JLR’s solar buildout isn’t just PR. Rooftop and ground-mounted solar cuts a manufacturer’s exposure to volatile grid electricity prices, reduces operational carbon emissions that feed into corporate net-zero commitments, and—for a car company pivoting toward electric vehicles—helps offset the extra grid demand that EV battery and drive-unit production creates.
