Solar Panels for Takeaways and Quick Service Restaurants
Per square metre, nothing in hospitality consumes electricity like a QSR kitchen. That intensity is exactly why the payback maths works — even for evening-led trade.
The most intensive kitchens in the business
A takeaway kitchen concentrates extraordinary electrical demand into a small footprint. Fryer banks, griddles, charbroilers, and rapid-cook ovens draw heavy power through every trading hour and idle hot between rushes. Holding cabinets, heated displays, and bain-maries run from open to close. Walk-in and reach-in refrigeration never stops, freezers carry the stockholding, and extraction canopies — legally required to run whenever cooking happens — pull their own continuous load. Sites running 11am to midnight, seven days, accumulate consumption figures that surprise even their owners when the bills are laid end to end.
High consumption is the raw material of solar economics. Every kilowatt-hour generated on the roof is purchased electricity avoided, and a building that consumes relentlessly gives generation somewhere useful to go for more hours of the day than the stereotype suggests. Lunch service, afternoon prep, weekend daytime trade, and the always-on refrigeration and holding loads mean a typical QSR self-consumes 50–70% of a sensibly sized array before any storage is added.
Where batteries earn their place
QSR is the one hospitality sub-sector where we recommend batteries more often than not. The reason is the evening peak: a venue taking most of its money between 5pm and 11pm wants its afternoon surplus moved into service hours. A battery sized at 10–20 kWh stores what the array over-produces after the lunch window and discharges it into the fryers at dinner, lifting self-consumption to 85% or higher. At roughly £400–£600 per kWh of capacity, the battery typically adds £5,000–£10,000 to the project and one to two years to the payback — then keeps adding value as evening rates and demand charges rise. We model it both ways from your actual trading pattern and show the comparison; for lunch-led sites we frequently advise against it, which tells you the modelling is honest.
The numbers for a typical site
A 15 kW takeaway system costs roughly £18,000–£23,000 installed and generates around 13,000 kWh a year. At 60% self-consumption and 2026 commercial rates, that is worth £2,500–£3,200 annually, with the Smart Export Guarantee adding a small margin on the surplus — a payback near five years, before the Annual Investment Allowance deducts the full cost from year-one taxable profits. Add a battery and the savings rise while the payback stretches slightly. The costs page carries the full worked tables, and the kitchen energy guide shows where the kilowatt-hours actually go.
Franchise estates and multi-site operators
Single-site owner-operators decide fast. Franchisees navigate the triangle of landlord, franchisor, and their own capital — workable in almost every case, since major QSR brands now carry public sustainability commitments that make a franchisee's solar proposal easy to approve. Multi-site operators get the most from portfolio treatment: one survey exercise across every roof, sites ranked by yield and tenure, capital deployed where it returns fastest. Drive-thru pads with wide flat roofs and long daytime trade typically top the ranking; tight high-street units under residential uppers fall off it — and we say so rather than padding the project list.
Install without losing service hours
Roof work for a 10–25 kW system takes two to six days and happens above trading. The power-down for final connection is two to four hours, scheduled before opening — for a site that opens at 11am, the connection is finished before the first fryer heats. Extraction positioning, grease management, and holding-temperature continuity during the window are all standard parts of our QSR method statement.
