Solar panels for food and drink manufacturing (UK)
Food and drink manufacturing is one of the UK's most electricity-intensive sectors. Continuous process loads, chilled and frozen storage, packaging lines, and CIP (clean-in-place) systems mean daytime consumption is high and steady — ideal for rooftop solar with 70–85% self-consumption.
Food & drink manufacturing — sector snapshot
Why solar fits food & drink manufacturing
- 24/7 refrigeration and freezing — solar directly offsets baseload.
- Big, uncluttered roofs on modern food plants.
- IETF (Industrial Energy Transformation Fund) grants for decarbonisation.
- Major retailer Scope 3 pressure — Tesco, Sainsbury's, M&S all demand emissions data from suppliers.
- Rising CO₂ prices under UK ETS make solar increasingly competitive.
Design considerations
- Process CIP boil-outs and evening cleans require battery for evening cover.
- Roof-mounted plant (extract, HVAC, ammonia refrigeration) reduces usable roof area 20–30%.
- Hygiene-critical zones — panels must not shed material or create pest access.
- Refrigeration compressors are a strong candidate for load-matching.
Funding routes
Full Expensing covers 100% of capex for UK limited companies. IETF grants of 30–50% capex are available for larger decarbonisation projects. PPA works well for 500 kWp+ arrays.

FAQ — solar for food & drink manufacturing
Can solar cover 24-hour food production?
Solar covers the daytime portion (roughly 30–50% of a 24-hour cycle) at scale. Paired with battery, that rises to 40–60%. Full 100% cover typically needs sleeved PPA or wind co-investment.
Do food-safety regulations restrict rooftop solar?
Solar itself is compatible with BRC and SALSA standards. Design must avoid ingress points and comply with pest-control protocols — standard for a food-plant install.
