Solar for Hotels with Restaurant Operations
Three services a day, rooms above, often a spa below — a hotel with F&B is the longest, flattest daytime load in hospitality, and the biggest roof to put to work.
Why hotel F&B changes the solar maths
A standalone restaurant gives solar a strong midday window. A hotel with a restaurant gives it the whole day. Breakfast service starts the kitchen before seven; lunch, afternoon tea, and conference catering carry it through the generation peak; dinner prep begins while the array is still producing. Around the kitchen, the hotel itself never pauses — housekeeping equipment, laundry, lifts, public-area HVAC, and domestic hot water all draw through daylight hours, and refrigeration holds the line around the clock. The aggregate effect is self-consumption near 90% on arrays far larger than any standalone venue could justify: 30–100 kW is the normal hotel range, against 15–50 kW for restaurants generally.
Scale improves the unit economics too. At 50 kW and above, cost per installed kilowatt falls towards £950, fixed costs spread across more panels, and the absolute savings become organisationally meaningful — £11,000–£23,000 a year for a well-sized hotel system at 2026 commercial rates. For an industry where energy sits among the top three operating costs behind payroll, that is margin recovered at the asset level, not the menu level.
Where the kilowatt-hours go in a hotel with F&B
The F&B operation typically accounts for a quarter to a half of a hotel's electricity: kitchen cooking and extraction, multiple refrigeration rooms, dish and glass washing on a near-continuous cycle, and bar service with its own cooling. Rooms and public areas take the rest, led by HVAC and hot water. The design consequence is that hotel arrays are sized to the building's daytime plateau rather than to any single department — and because that plateau is high and long, hotel systems rarely export much. Where a property also runs wet leisure, the pool plant absorbs surplus generation almost without limit; for pool-specific design detail, see solarpanelsforswimmingpools.co.uk, and for the broader rooms-led picture, solarpanelsforhotels.co.uk.
The numbers at hotel scale
A 50 kW system costs roughly £45,000–£65,000 installed and generates in the region of 42,000–45,000 kWh a year. At 88% self-consumption and a 30p/kWh blended commercial rate, the avoided purchases are worth £11,000–£12,000 annually before export income — a payback near five years. The £1m Annual Investment Allowance usually means 100% relief in year one for a business under the limit (the 0% VAT rate is domestic-only; VAT-registered hotel businesses reclaim the standard-rated VAT as normal). Larger properties stacking 100 kW see proportionally stronger returns. Worked examples by venue type are on the costs page; the tax mechanics are in the capital allowances guide.
Heritage properties and planning
Country house hotels and city-centre heritage buildings carry the same planning considerations as listed pubs: Listed Building Consent where applicable, conservation-area restrictions on visible slopes, and a preference for flat roofs behind parapets, rear elevations, and outbuildings — stable blocks, spa wings, and event barns frequently host the array even when the main house cannot. Solar on an unlisted commercial building often needs no planning application, but listed buildings and conservation areas have extra rules — check with the local planning authority before design money is spent.
Installing around guests
A hotel cannot easily close for an installation, so the working arrangements are worth agreeing with the installer in advance. Roof work is normally planned in zones agreed with the general manager — typically two to six weeks for hotel-scale systems — with scaffolding screened away from arrival views and quiet hours set around guest floors. The grid connection power-down of two to four hours is ideally placed on the lowest-occupancy morning of the programme, with kitchen refrigeration and life-safety systems covered through the window by a method statement your maintenance team signs off in advance. Ask any installer to put the zones, quiet hours and power-down date in writing before work starts.
