How big is the solar system installed at Uniroyal Global?
Alliant Energy installed a 999.58kWp solar PV system using 2272 panels paired with a SolarEdge inverter. The installation took 10 weeks from arrival on site to commissioning.

Project overview
Being able to work with Alliant Energy on this project on a Power Purchase Agreement has enabled us to implement our green energy strategy earlier meaning Uniroyal will make savings from day one enabling us to invest into other areas of the Uniroyal Global business. Alliant Energy has been a great support throughout the process and we are looking forward to seeing the finished result and reaping the rewards. The installation in place at Uniroyal Global represents a huge commitment to carbon reduction from the Earby based business. The large solar PV installation will save almost 300,000 kg of CO2 per year, and will also provide a cost saving to Uniroyal of over £2 million spanning a 10 year period.
The challenge
Like most manufacturing operations, Uniroyal Global faced a structural exposure to wholesale electricity prices — a cost line that doubled for many UK businesses between 2021 and 2023 and shows no sign of returning to pre-crisis levels. With significant daytime load and suitable roof space, on-site generation was the obvious lever, but the project needed to stand on its own commercial merits: predictable payback, manufacturer-backed warranties, and zero operational disruption during install.
The solution Alliant Energy designed
Following a structural roof survey and DNO capacity check, Alliant Energy specified a 999.58kWp array using 2272 high-efficiency mono-PERC panels, paired with a SolarEdge hybrid inverter. The SolarEdge platform was chosen for its export-management capability and remote firmware updates, allowing the array to be tuned over its life without site visits. Surplus generation is exported to the grid under a Smart Export Guarantee tariff, providing a secondary revenue stream alongside the primary saving on imported electricity.
Install & commissioning
The full installation completed in 10 weeks, scheduled around the customer's operating hours to avoid downtime. Work was carried out by Alliant Energy's directly employed MCS-registered engineers — no subcontracted labour. The system was commissioned to G99 requirements, registered with the Microgeneration Certification Scheme, and handed over with monitoring access, electrical certification, and structural sign-off documents on the day of completion.
Financial outcome
In its first full year of operation the system is on track to save Uniroyal Global approximately £115,462 on electricity costs, with a payback term of 6 Years and a projected total ROI of 417%. Over the 25-year warranted life of the panels, the cumulative saving is forecast at £2.89M — a figure that improves materially if grid prices continue their long-term upward trend, and that benefits from the UK's 100% full-expensing capital allowance for qualifying solar assets.
Environmental impact
The installation displaces roughly 279.4 Tonnes of CO₂ emissions every year compared with grid-sourced electricity. Over the system's 25-year design life that is the equivalent of removing more than Uniroyal Global's entire annual Scope 2 footprint several times over — a material data point for ESG, B-Corp and net-zero reporting frameworks.
Why it matters for the manufacturing sector
Manufacturing businesses typically run daytime electrical loads — refrigeration, machinery, IT, lighting, compressors — that overlap closely with solar generation. That overlap is what drives strong economics: every unit generated and consumed on-site replaces a unit that would otherwise be bought from the grid at full commercial rates. The Uniroyal Global project demonstrates how the model scales for this kind of operation.

Project FAQ
How much does Uniroyal Global save each year?
Uniroyal Global saves approximately £115,462 per year on electricity, with projected lifetime savings of £2.89M over the system's 25-year guaranteed performance period. The payback term is 6 Years, delivering a total ROI of 417%.
Was the project funded or paid for upfront?
This project was paid for directly by the customer. Under the UK's full-expensing capital allowance, the entire cost can be deducted from corporation tax in year one — improving the effective payback meaningfully for profitable companies.
What's the environmental impact?
The system avoids around 279.4 Tonnes of CO₂ emissions every year compared with grid-sourced electricity. Over a 25-year design life that's a material contribution toward Scope 2 reduction and any ESG or net-zero reporting commitments the business holds.
Could a similar system work for my business?
Probably — the same hardware platform (panels, hybrid inverter, optional battery) scales from roughly 10kW up to 1MW+. The deciding factors are roof area, daytime electricity use, current unit rate, and grid-connection capacity.
