Solar panels for takeaways — UK Specialist Installer

Why solar PV works exceptionally well for takeaways

UK takeaways and fast food businesses are one of the strongest hospitality sub-sectors for commercial solar economics in 2026. Three structural factors stack: extended trading hours (most takeaways run 11am-11pm or 12noon-12am, capturing both midday and evening peaks), high-density kitchen baseload (commercial fryers, ovens, grills, hot-hold cabinets, refrigeration, ice machines, drinks chillers — disproportionately large electricity demand for the small footprint), and consistent daytime opening (unlike restaurants with a midday lull, most takeaways trade continuously through the afternoon for delivery + walk-in orders).

The combined effect: takeaway self-consumption ratios routinely hit 80-90% even without battery storage. Compare to standard offices (55-70%), retail (60-75%), or restaurants (75-85%). This high self-consumption means solar economics are exceptionally strong — every kWh generated displaces grid electricity at the full retail tariff rather than exporting at the lower SEG rate.

Add to this that takeaways typically operate on commercial tariffs of 26-32p/kWh in 2026 (higher than national commercial average due to small-business pricing), and the per-kWh saving when self-consuming solar generation is substantial. Typical payback for takeaway solar is 5-6 years gross, dropping to 3.8-4.5 years net of 100% Annual Investment Allowance tax relief for profitable limited companies.

The fourth factor: takeaway business owners are often capex-constrained (small business cash flow priorities) but well-suited to asset finance routes. 7-year asset finance on a typical £25,000 25 kW takeaway install means monthly payments of approximately £400 against monthly bill savings of £450-£550 — cash-flow positive from month one with no capex outlay.

The fifth factor: brand and customer trust. Takeaways increasingly compete on sustainability messaging — particularly food-quality-led independents and chains targeting younger demographics. Visible solar generation, “powered by sunshine” branding, and published kWh counters all support the customer narrative.

System sizing for takeaways

Sizing for takeaways typically lands between 15 kW and 50 kW based on annual demand and roof area. A 15-20 kW system suits a small independent takeaway with annual demand 18,000-25,000 kWh. A 30-50 kW system suits a larger fast-food outlet, multi-cuisine takeaway, or pub-with-kitchen-as-takeaway with annual demand 40,000-65,000 kWh.

Annual demand correlates strongly with kitchen complexity. Pizza takeaways with stone-deck ovens, fish-and-chip shops with large fryer banks, and Chinese takeaways with multiple woks + steamers + rice cookers all run high kitchen loads. Combined with refrigeration (raw ingredient storage, drinks chillers, ice machines), kitchen + cold loads typically account for 75-85% of takeaway electricity consumption.

Self-consumption ratio for takeaways is the highest in commercial PV — typically 80-90% even on standalone solar without battery. This is unusual and makes sizing-to-demand more straightforward than other sub-verticals.

Roof area constraint: takeaways typically operate in small premises (60-200 sqm floor area) with correspondingly small roof areas. A 30 kW system needs approximately 170 sqm of usable south, east, or west-facing roof — and many takeaway shop-fronts simply don’t have this. Mid-terrace takeaway units in particular face roof access challenges. Where roof area is binding, we evaluate adjacent buildings (often part of the same lease), rear additions, and outbuildings.

Cost and payback for takeaways

A 15-50 kW takeaway solar system in 2026 costs £15,000-£47,500 turnkey (£950-£1,100/kW for sub-50 kW systems). Pricing includes tier-1 monocrystalline modules, three-phase string inverters (Sungrow, Solis, SMA), mounting, scaffolding, DC and AC cabling, G98 paperwork, MCS certification, commissioning, and 25-year performance warranties.

Worked example. A 5-day-a-week fish-and-chip shop in a small town centre, 80 sqm floor area, annual demand 28,000 kWh, current import tariff 28p/kWh. Solar specification: 25 kW pitched south-facing array on the unshaded roof above (single-storey shop building). Capex: £25,000 turnkey (£1,000/kW). Generation: 24,000 kWh/year (P50, Midlands location 960 kWh/kWp). Self-consumption: 88% (21,120 kWh self-consumed, 2,880 kWh exported). Year-one savings: £5,914 avoided import + £173 SEG = £6,087. AIA tax relief: £6,250. Net effective capex: £18,750. Simple payback: 4.1 years gross, 3.1 years net. 25-year DCF NPV at 7%: £108,000. IRR: 23.5%.

Financing: most takeaway operators use 7-year asset finance (monthly payment £370 on £25k capex vs £510 monthly savings = +£140/month cash flow positive from month one + ownership at end of term). Cash + AIA for operators with capex headroom (strongest 23.5% IRR). PPA generally not available at sub-50 kW takeaway scale — deal too small for PPA provider unit economics.

Compliance and regulation

Most takeaway solar installs fall under Permitted Development Rights — no full planning permission required for rear-facing rooftop solar on freehold non-listed buildings. Exceptions: listed buildings (Listed Building Consent), conservation areas (planning permission for visible roof areas), shop fronts in designated retail conservation areas.

DNO connection: all takeaway solar is below 100 kW so G98 “Connect and Notify” process applies (4-8 week DNO timeline). Application fee £350-£500. No reinforcement risk at this scale.

Health and safety: standard commercial solar H&S applies. Note that takeaway kitchens have unusually high cooking-related fire risk — solar DC isolation and arc-fault detection integrated with the venue’s fire alarm system is recommended (we design as standard).

Insurance: building insurer notification needed; typically nil premium impact for modern PV. Some insurers require BAFE-registered fire risk assessor sign-off on kitchen-adjacent PV installations.

Landlord consent: if leasehold (very common for takeaways), landlord consent for the install is required. We provide standard landlord consent letters covering structural / insurance / fixtures aspects.

A typical takeaway install scenario

An independent takeaway in a suburb of Leeds — gourmet burger and pizza concept, 90 sqm floor area, 12 staff, single-phase 100A supply, 11am-11pm Tue-Sun trading, annual demand 35,000 kWh, current import tariff 28p/kWh. Solar specification: 22 kW pitched east-facing array on the unshaded shop-roof above (the southern orientation is shaded by the adjacent 3-storey building). Capex: £24,200 turnkey. Generation: 19,500 kWh/year (P50, east-facing deration). Self-consumption: 90% (17,550 kWh self-consumed, 1,950 kWh exported). Year-one savings: £4,914 avoided import + £117 SEG = £5,031. AIA tax relief: £6,050. Net effective capex: £18,150. Simple payback: 4.8 years gross, 3.6 years net. Asset finance route: £360/month vs £420/month savings = +£60/month cash positive from month one.

Sector-specific FAQs

Can I install solar on a takeaway with a single-phase electricity supply? Yes for systems up to 17 kW (single-phase total cap on commercial connections). Above 17 kW you need either a three-phase supply upgrade (£3,000-£15,000 one-time cost) or limit the system to single-phase capacity. Most small takeaways install 15-17 kW systems on single-phase supplies, getting the maximum benefit without upgrade cost.

What’s the cheapest way to get started with takeaway solar? Asset finance with 7-year term and no upfront payment. Typical £20,000 20 kW install becomes a £300/month commitment, more than offset by monthly bill savings of £350-£420. Effectively zero-impact on cash flow with zero capex outlay.

Does takeaway solar disrupt operations during install? Minimal disruption. Typical 25 kW install: 4-6 weeks DNO process (zero on-site activity), 1 day scaffolding (overnight or pre-opening), 2-3 days panel installation (rooftop only, kitchen continues normal operation), 1 day commissioning (requires 2-hour power-down outside trading hours, typically Tuesday or Wednesday morning). Total disruption: 2 hours of trading time.
