Restaurant Solar Panels for Hotels & F&B Operations

Independent & supplier-neutral · Reviewed September 2026

Restaurant solar panels are the highest-yield use of a hotel roof when the property runs a substantial food-and-beverage operation — typically a 70+ cover restaurant, banqueting, bar trade and event catering. The electricity demand profile is distinctive: commercial kitchen refrigeration runs 24/7, kitchen ventilation peaks during prep and service, water heating for dishwashing and plate warming runs from breakfast onwards, and dining-area lighting and HVAC track guest occupancy. Modelled together, that profile self-consumes 90–95% of what the array generates — among the strongest figures in UK commercial solar. This page sets out what restaurant solar panels cost, how they are funded, why the grid connection is the first job, and how an installation is sequenced around service hours.

The hotel F&B electricity load profile

A modelled 80-room hotel with full F&B operations (breakfast service, lunch, a full dinner restaurant, bar and banqueting) draws in the region of 280,000–380,000 kWh a year of electricity. Within that, the F&B share typically breaks down as:

• Commercial kitchen equipment: 25–35% — walk-in chillers, blast freezers, prep fridges, electric ranges, combi-ovens, induction hobs, dishwashers
• Kitchen ventilation: 12–18% — extraction fans, make-up air systems, grease management
• Water heating: 8–14% — dishwashing, plate warming, kitchen prep
• Front-of-house refrigeration: 4–8% — wine cellars, bar refrigeration, beer cellars
• Dining-area lighting and HVAC: 6–10%

Together, F&B operations account for roughly 55–75% of total hotel electricity in F&B-led properties. The load is heavily daytime-weighted — breakfast from 06:30, lunch prep and service 11:00–15:00, dinner prep and service 17:00–22:00 — which is why restaurant solar panels align so closely with generation hours. These shares are modelled from typical UK hospitality demand patterns; your own half-hourly data replaces them the moment a proposal is built.

Walk-in chiller and refrigeration alignment

Commercial walk-in chillers and blast freezers are the highest-value self-consumption load in hotel F&B. Both run continuously, both draw a substantial constant load (typically 1.5–4.5 kW per walk-in unit on UK hotel installations), and both have predictable profiles independent of weather or occupancy. Installers routinely size an array specifically to cover the walk-in chiller and freezer base load, so these food-safety-critical systems run on the array's output through daylight hours and only draw from the grid at night.

What restaurant solar panels cost

UK commercial solar in 2026 runs roughly £800–£1,200 per installed kW depending on scale, roof access and structural work — the same benchmark band used across our hotel solar cost data. Applied to typical restaurant sizes, the modelled capex bands are:

These are modelled bands, not quotes. Two things move a real project outside them: scaffolding and roof penetrations around kitchen extract terminals (which add cost), and a DNO connection upgrade if the existing supply cannot accept the export (which can add both cost and months). A quote that arrives without a self-consumption model built from your meter data is a quote to question — see what a good hotel solar quote includes.

Funding and tax: what applies to restaurant solar panels — and what does not

There is no general UK grant for commercial solar on a restaurant or hotel. The routes that actually apply in 2026:

• Annual Investment Allowance (AIA). Solar PV is special-rate plant, so the year-one route for a tax-paying operator is the AIA — 100% first-year relief on qualifying capex up to £1m a year. At the 25% main rate that is worth roughly 25p per £1 of capex in the year of installation. Capex above the £1m cap attracts the 50% special-rate first-year allowance.
• Full expensing does not reach solar. Because solar is special-rate expenditure (HMRC Capital Allowances Manual CA22335), the headline "full expensing" regime for main-rate plant does not apply. Any proposal that shows full expensing on a solar line is wrong.
• VAT. The 0% VAT rate on energy-saving materials covers residential accommodation and relevant charitable buildings; a trading restaurant or hotel is standard-rated, and the VAT is normally recoverable in the usual way.
• Power Purchase Agreement (PPA). A third party funds, owns and maintains the array and sells the power at a fixed tariff below grid retail — zero capex, positive cashflow from month one, 15–25 year term with a buyout option. The default route for managed-contract, franchise and capital-light properties. PPA structuring guide.
• Hire purchase / asset finance. Spreads capex over 5–7 years while the operator owns the asset from day one, so AIA still applies.

G99 first: why a restaurant array needs a DNO application

The grid connection is the step most restaurant projects underestimate. The simplified G98 route covers an aggregate registered capacity of 16 A — 3.68 kW — per phase or less; anything above that needs a G99 application to the District Network Operator. A single 4 kW inverter already draws about 17.4 A per phase, so a kitchen-scale array of 25–250 kW is a G99 project without exception.

G99 means a DNO study and, on some networks, reinforcement or a connection upgrade before the array can be energised. The response time runs to months, which makes it the longest item in almost every programme — and the one that decides whether a target commissioning date is deliverable. Sequence it first: the application can run in parallel with design, planning and any Listed Building Consent, and nothing on site should be ordered until the DNO offer is in hand. Which DNO you deal with depends on the property's location — the site's UK Power Networks, Northern Powergrid and SP Energy Networks guides cover the regional processes.

The process: from meter data to commissioning around service hours

1. Desk feasibility from half-hourly data. Twelve months of half-hourly consumption, modelled against a roof-specific generation profile, shows the self-consumption rate and the right array size before anyone visits.
2. Roof and extract survey. Kitchen extract terminals, grease-laden air discharge and make-up air intakes fix where panels cannot go and where scaffolding must avoid. Structural check on the roof build-up.
3. G99 application and consents. DNO application in first; planning or Listed Building Consent where the building needs it; brand engineering approval for chain properties — all in parallel.
4. Design and specification. Tier-1 MCS-certified panels, string or central inverters sized to the kitchen base load, monitoring specified.
5. Install. Roof work runs above the kitchen during normal trading; the one disruptive moment is the grid sync and any brief power isolation, which the installer should schedule for an overnight or pre-service morning window agreed with the head chef or F&B manager.
6. Commission, monitor, maintain. Live generation monitoring and an optional O&M contract for cleaning, inverter servicing and performance reporting.

Restaurant-led hotels — the strongest economics

Restaurant-led hotels — typically 6–20 rooms above a 60–100 cover destination restaurant — model as one of the strongest fits in hospitality. The F&B load dominates total property demand (typically 75–85%), daytime hours align tightly with generation, and the small accommodation block means low overnight demand. Modelled self-consumption on a properly sized system is 92–95%.

Modelled example for a 12-room restaurant-led country property with an 80-cover destination restaurant: annual electricity 165,000 kWh, a 130 kW array, capex around £130,000 at the mid-point of the 2026 band, year-1 saving in the region of £33,000, simple payback about 4 years before the AIA tax shield and about 3 years after it. Illustrative — assumes 2026 benchmark pricing and current grid rates; your figures come from your own meter data.

Food Hygiene Reg 852/2004 and HACCP considerations

UK hotel restaurant kitchens operate under the Food Hygiene Regulations 2006 (implementing EU Reg 852/2004) with HACCP-aligned protocols. A solar PV installation has no direct food-hygiene impact provided standard MCS commercial certification protocols are followed. The installer should agree the schedule with the HACCP-trained head chef or F&B manager so that no work occurs during food prep or service, and so that any electrical isolation is brief and falls in an overnight or pre-service window. Where the property is heritage-listed, the listed building solar guide covers the additional consent step.
