[ Previous Clitheroe Residential — Sigenergy ](/case-study/clitheroe-residential-sigenergy)[ Next Barnoldswick Residential ](/case-study/barnoldswick-residential) ## Project overview Another home in Reedley, Burnley is now generating its own electricity. 12 all-black panels, an 8kW Sigenergy hybrid inverter and 9kWh Sigenergy battery storage — fitted by Alliant Energy's in-house team from start to finish. Tidy install, designed properly around the roof. This homeowner is set to save over £2,000 a year on their energy bills — no more worrying about rising monthly energy costs, no more being fully exposed to price hikes, just clean power generated straight from the roof. The system slashes energy bills, locks in protection against rising prices, and turns the home into its own power station. Through the Sigenergy app the homeowner gets real-time monitoring of everything the system generates and uses, full control from their phone, smart energy management so nothing goes to waste, and automatic access to the best export tariffs — getting paid for the energy they don't use. It might not always look sunny up here in the North West, but that's exactly why the right system design matters. Alliant Energy starts every job with a drone survey, designs the system around your actual roof, and handles the full installation in-house. No mess. No hassle. No cutting corners. ### The challenge Like most domestic / residential operations, Reedley, Burnley Residential 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 5.64kWp array using 12 × 470W high-efficiency mono-PERC panels, paired with a Sigenergy 8kW Hybrid hybrid inverter and 9kWh Sigenergy of lithium iron phosphate (LFP) battery storage. The Sigenergy 8kW Hybrid 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%. ### Install & commissioning The full installation completed in 2 days, 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 Reedley, Burnley Residential approximately **£2,050** on electricity costs, with a payback term of **5.6 Years** and a projected total ROI of **540%**. Over the 25-year warranted life of the panels, the cumulative saving is forecast at **£51,250** — 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 **1.4 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 Reedley, Burnley Residential'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 domestic / residential sector Domestic / Residential 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 Reedley, Burnley Residential project demonstrates how the model scales for this kind of operation. System 5.64kWp Panels 12 × 470W Inverter Sigenergy 8kW Hybrid Storage 9kWh Sigenergy Install 2 Days ### Project FAQ ### How big is the solar system installed at Reedley, Burnley Residential? Alliant Energy installed a 5.64kWp solar PV system using 12 × 470W panels paired with a Sigenergy 8kW Hybrid inverter and 9kWh Sigenergy of battery storage. The installation took 2 days from arrival on site to commissioning. ### How much does Reedley, Burnley Residential save each year? Reedley, Burnley Residential saves approximately £2,050 per year on electricity, with projected lifetime savings of £51,250 over the system's 25-year guaranteed performance period. The payback term is 5.6 Years, delivering a total ROI of 540%. ### 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 1.4 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. Alliant Energy carries out a free desktop feasibility study and follow-up site survey before quoting. ### Financial impact Rate of ROI 18% Total ROI 540% Annual savings £2,050 Lifetime savings £51,250 Payback term 5.6 Years Annual CO₂ saved 1.4 Tonnes [Commercial Savings Calculator →](/calculator) ### More projects [ Frozen Dessert Distribution Tropical Ices £13,700/yr · 5 Years payback ](/case-study/tropical-ices)[ Pewter & Silverware Manufacturing Pinder Brothers £3,700/yr · 5 Years payback ](/case-study/pinder-brothers)[ Logistics & Haulage Shepherd Distribution £22,389/yr · 2.9 Years payback ](/case-study/shepherd-distribution)[ Retail Technology Datascan Retail Systems £3,457/yr · 5.9 Years payback ](/case-study/datascan-retail-systems) Three ways to get started ## Ready to find out what solar saves you?
