Commercial solar for hospitality.

Commercial solar suits hotels and conference venues because the load runs through the daylight hours. This page is for the operators of hotels, conference centres, event venues, restaurants and pubs with rooms: buildings that never really switch off. A hospitality site carries a base load it cannot avoid, from refrigeration and hot-water plant to lifts, lighting and air handling, and it layers a variable load on top whenever the kitchen is busy or a function room fills.

That combination is worth modelling for solar. The roof on a hotel block or a conference hall is often far larger than the footprint suggests, and the demand underneath it runs through the daylight hours when an array generates most. For a building over 50 kWp, where the system sits outside MCS and is assured by the engineering stack instead, the question is not whether the roof can hold panels. It is how much of the generation your operation actually consumes.

Solar pays best when the electricity is used on the spot. A unit consumed on site offsets an expensive import unit, while a unit exported to the grid is paid far less. So the return on a hospitality system tracks how closely generation lines up with demand through the day, not the panel count on the roof.

Hospitality tends to line up well. Commercial kitchens run extraction, refrigeration and cooking load across long service hours. Hot water and laundry draw steadily, and in a hotel the demand carries into the evening as guests arrive and rooms fill. HVAC and ventilation often climb through the afternoon, which overlaps the strongest part of the generation curve. The result is a load shape that self-consumes a useful share rather than spilling cheaply to export. The shape does vary by format. A function-led venue can sit quiet between events, and occupancy is rarely flat across the week, so we read the real half-hourly profile rather than assume a sector average. Where the daytime match is weaker, battery storage to shift generation into the evening peak, or a portfolio view across several sites, is worth looking at.

A hospitality site typically lands in the 50 to 250 kWp range, spread across the large roofs of a hotel block, a conference hall or a leisure and spa wing. Many carry shallow-pitch or flat roof areas that take a clean, well-orientated array, though plant rooms, rooftop air-handling units and parapets all eat into the usable area and need designing around. That band is indicative only, a sense of scale for the sector and not a quote. The real figure comes from the survey and the PV*SOL model built for your exact roof and your actual load.

Self-consumption is the whole game above 50 kWp. A unit generated and used on site displaces an expensive import unit; a unit exported to the grid is paid far less. So the return on a hospitality array tracks how closely generation lines up with demand through the day, far more than it tracks the panel count on the roof. Reading that match for your building means looking at your own half-hourly metering data rather than a sector average, because the load shape behind a 90-bedroom conference hotel and a function-led wedding barn could not be more different.

The format decides the profile, and the profile decides the design. A hotel carries a steady base load that never really switches off: refrigeration, hot-water plant, lifts, corridor lighting and ventilation run around the clock, much like the year-round continuous demand behind a leisure centre or pool. A conference or wedding venue sits quiet between bookings and then spikes hard when a function fills the kitchen, the bar and the air-handling plant at once. Sites with a spa or pool wing add a continuous plant load on top of either pattern. That mix of steady base and sharp event peaks is exactly what we model before sizing anything, because it sets how much of the roof's output you actually keep rather than spill cheaply to export.

Where the load lands through the day matters as much as how much there is. Commercial kitchens run extraction, refrigeration and cooking across long service hours, hot water and laundry draw steadily, and HVAC tends to climb through the afternoon, which overlaps the strongest part of the generation curve. In a hotel the demand carries into the evening as guests arrive and rooms fill, which is the part of the day an array no longer covers. That evening shoulder is where commercial battery storage can earn its place, shifting midday generation into the check-in and dinner peak rather than exporting it. We weigh that against simply sizing the array to the daytime load, and where the case for storage is marginal we say so.

The honest caveat is the quiet period. A function-led venue with gaps between events, or a seasonal hotel that winds down through the shoulder months, will export more of its generation when the building is empty. We do not paper over that. We model the real half-hourly and seasonal shape, size the array to the demand the operation actually carries across the year, and look at whether storage, a sensible export route for the genuinely quiet months, or an estate-wide view across several sites improves the match more than overbuilding a roof. Any kWh/kWp yield or self-consumption split we mention is a starting point we confirm in the PV*SOL model built for your roof and your load, not a guaranteed output.

A hospitality roof is rarely a single clean plane. A hotel estate often mixes a flat membrane over the function rooms, a shallow-pitch metal deck over the bedroom block and a separate plant or leisure wing, each with its own age, orientation and structural headroom. Plant rooms, lift overruns, rooftop air-handling units, kitchen flues and parapets all eat into the usable area and cast shading that has to be designed around rather than averaged out. Our in-house drone survey captures that geometry directly and feeds an accurate 3D model, so the array is laid out around the real obstructions and the shading is modelled per string rather than estimated from a flat roof-area figure.

Above 50 kWp the assurance comes from the engineering stack rather than a domestic certificate. MCS is the residential scheme and does not apply at this scale, so the right evidence is the work itself: design and installation to BS 7671, system verification and commissioning to IEC 62446-1, a G99 connection agreement with the DNO, and an RC62 recommendation and insurance-backed guarantee on completion. CDM 2015 applies to every project, with the appropriate principal designer and principal contractor roles appointed, which matters on an occupied, trading hotel where the works share the site with guests and staff. We sequence the roof work around your fire strategy, escape routes and trading calendar so the install does not compromise either.

On scale, a hospitality system typically lands in the 50 to 250 kWp range. Smaller boutique hotels and pubs with rooms sit toward the 50 to 150 kWp band, while a larger conference hotel or a multi-building resort can reach the 200 to 300 kWp band once the function space and back-of-house roofs are counted in. That band is indicative only, a sense of scale and not a quote; the real figure comes from the survey and the PV*SOL model built for your exact roof and load.

How the spend is funded shapes the business case as much as the kit. The same model that sizes the array feeds the numbers, and capital outlay on a qualifying solar system can attract capital allowances against your tax bill. Whether you buy outright, lease or fund through a power purchase agreement is set out in the commercial finance options, where any payback or bill-reduction figure is modelled for your site and disclosed with its basis, never promised as a flat sector number.
