Moorwood Farm

Like most agriculture operations, Moorwood Farm 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.

Following a structural roof survey and DNO capacity check, Alliant Energy specified a 45kW array using 90 high-efficiency mono-PERC panels, paired with a 150kW hybrid inverter and 20.5kW of lithium iron phosphate (LFP) battery storage. The 150kW platform was chosen for its export-management capability and remote firmware updates, allowing the array to be tuned over its life without site visits. Battery storage was sized to absorb mid-day generation peaks and discharge across the early evening, lifting on-site solar self-consumption from a typical 35–45% to over 70%.

The full installation completed in 4 days, scheduled around the customer's operating hours to avoid downtime. Work was carried out by Alliant Energy's directly employed Experienced 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.

In its first full year of operation the system is on track to save Moorwood Farm approximately £7,052 on electricity costs, with a payback term of 4.8 Years and a projected total ROI of 956%. Over the 25-year warranted life of the panels, the cumulative saving is forecast at £361,928 — 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.

The installation displaces roughly 9 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 Moorwood Farm's entire annual Scope 2 footprint several times over — a material data point for ESG, B-Corp and net-zero reporting frameworks.

Agriculture 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 Moorwood Farm project demonstrates how the model scales for this kind of operation.
