[ Previous Pinder Brothers ](/case-study/pinder-brothers)[ Next Datascan Retail Systems ](/case-study/datascan-retail-systems) ## Project overview Originally established in 1946 as a steel haulier, Shepherd Distribution has grown through their outstanding reputation. Their large south-facing roof allowed 108 Tenka solar panels, paired with a 50kW three-phase Sunsynk hybrid inverter and a 61.44kW high-voltage Sunsynk battery rack. ### The challenge Like most logistics & haulage operations, Shepherd Distribution 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 65kW array using 108 high-efficiency mono-PERC panels, paired with a 50kW hybrid inverter and 62kW of lithium iron phosphate (LFP) battery storage. The 50kW 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 4 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 Shepherd Distribution approximately **£22,389** on electricity costs, with a payback term of **2.9 Years** and a projected total ROI of **1,790%**. Over the 25-year warranted life of the panels, the cumulative saving is forecast at **£1,239,410** — 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 **13 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 Shepherd Distribution'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 logistics & haulage sector Logistics & Haulage 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 Shepherd Distribution project demonstrates how the model scales for this kind of operation. System 65kW Panels 108 Inverter 50kW Storage 62kW Install 4 Days ### Project FAQ ### How big is the solar system installed at Shepherd Distribution? Alliant Energy installed a 65kW solar PV system using 108 panels paired with a 50kW inverter and 62kW of battery storage. The installation took 4 days from arrival on site to commissioning. ### How much does Shepherd Distribution save each year? Shepherd Distribution saves approximately £22,389 per year on electricity, with projected lifetime savings of £1,239,410 over the system's 25-year guaranteed performance period. The payback term is 2.9 Years, delivering a total ROI of 1,790%. ### 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 13 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 38.7% Total ROI 1,790% Annual savings £22,389 Lifetime savings £1,239,410 Payback term 2.9 Years Annual CO₂ saved 13 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)[ Retail Technology Datascan Retail Systems £3,457/yr · 5.9 Years payback ](/case-study/datascan-retail-systems)[ Car Dealership Geoff Cox Automotive £6,816/yr · 5.8 Years payback ](/case-study/geoff-cox-automotive) Three ways to get started ## Ready to find out what solar saves you?
