Commercial solar PV case studies
Representative commercial solar PV projects across the UK. The figures below are modelled from real building profiles and typical UK irradiance, and show the kind of system, saving and payback we design and deliver.
180 kW rooftop system on a Midlands distribution warehouse
A third-party logistics operator running a 2,800 sqm distribution unit near Birmingham with £96,000 a year in electricity, driven by lighting, forklift charging and refrigeration. The board wanted a fast payback and no capex on the balance sheet.
- System size
- 182 kW (330 panels, non-penetrative clip-fix)
- Annual generation
- 168,000 kWh
- Annual saving
- £38,000
- Simple payback
- 5.5 years
Outcome: Funded on a 6-year asset-finance agreement, cash-flow positive from month one. 78% self-consumption from daytime MHE charging. The renewable disclosure helped retain a Tier-1 retail contract.
60 kW office and showroom install in the South West
A 40-person professional-services firm in a converted 900 sqm office and showroom near Bristol, paying £22,000 a year for electricity and fielding sustainability questions from corporate clients.
- System size
- 60 kW (110 panels, pitched-roof fixed mount)
- Annual generation
- 55,000 kWh
- Annual saving
- £13,500
- Simple payback
- 6.5 years
Outcome: Self-funded with 100% AIA tax relief. EPC rating lifted from C to B, supporting MEES compliance. A lobby display shows live generation to visiting clients.
750 kW factory system with battery storage in the North West
A food manufacturer running a 24/5 process line in a 9,000 sqm plant with £310,000 annual electricity spend. High, steady daytime load made solar the strongest capital project on the table.
- System size
- 750 kW rooftop PV plus 400 kWh battery
- Annual generation
- 690,000 kWh
- Annual saving
- £165,000
- Simple payback
- 4.5 years
Outcome: Part-funded through the Industrial Energy Transformation Fund with the balance on cash purchase. 88% self-consumption; the battery covers the early-shift ramp before peak generation.
