[ Previous Geoff Cox Automotive ](/case-study/geoff-cox-automotive)[ Next Lostock Cricket Club ](/case-study/lostock-cricket-club) ## Project overview Excel Martial Arts has served the local community for over 15 years and is open 7 days a week. Their system included 56 Hyundai panels, a 30kW three-phase FoxESS hybrid inverter and 4 x 4.74kW (18.96kW) battery storage. ### The challenge Like most community sports operations, Excel Martial Arts 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 33kW array using 56 high-efficiency mono-PERC panels, paired with a 30kW hybrid inverter and 19kW of lithium iron phosphate (LFP) battery storage. The 30kW 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 3 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 Excel Martial Arts approximately **£5,615** on electricity costs, with a payback term of **5.9 Years** and a projected total ROI of **742%**. Over the 25-year warranted life of the panels, the cumulative saving is forecast at **£275,466** — 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 **9.4 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 Excel Martial Arts'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 community sports sector Community Sports 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 Excel Martial Arts project demonstrates how the model scales for this kind of operation. System 33kW Panels 56 Inverter 30kW Storage 19kW Install 3 Days ### Project FAQ ### How big is the solar system installed at Excel Martial Arts? Alliant Energy installed a 33kW solar PV system using 56 panels paired with a 30kW inverter and 19kW of battery storage. The installation took 3 days from arrival on site to commissioning. ### How much does Excel Martial Arts save each year? Excel Martial Arts saves approximately £5,615 per year on electricity, with projected lifetime savings of £275,466 over the system's 25-year guaranteed performance period. The payback term is 5.9 Years, delivering a total ROI of 742%. ### Was the project funded or paid for upfront? Yes — this project was delivered with funding support (grant or asset finance). Alliant Energy helps eligible UK businesses access capital allowances under full expensing, asset-finance facilities, and Power Purchase Agreements (PPAs) so solar can be installed with little or no upfront cost. ### What's the environmental impact? The system avoids around 9.4 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 20.7% Total ROI 742% Annual savings £5,615 Lifetime savings £275,466 Payback term 5.9 Years Annual CO₂ saved 9.4 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?
