Solar for pools, pitches and leisure centres

Sports venues split into two kinds of building with almost opposite profiles. A wet leisure centre runs a heavy, flat, continuous load: pool circulation and filtration pumps, pool water heating, air handling to control humidity, and changing room hot water. It barely dips, day or night, summer or winter.

A stadium, clubhouse or dry pitch facility is the opposite. It sits close to idle for most of the week and then peaks hard on match or event days, in the evening, under floodlights. Annual consumption can be modest while the peak half hour is enormous.

Those two shapes lead to completely different recommendations, which is why lumping the sector together produces bad advice. Pool sites are among the strongest solar candidates in the public estate. Event driven venues usually need the conversation to start somewhere other than panels.

In a leisure centre, plant runs to a schedule set by water quality and air quality rather than by opening hours. Filtration turnover continues overnight, dehumidification runs whenever the hall is warm and wet, and heating is continuous because letting a pool cool down costs more than holding it.

Against that background load, generation is absorbed almost entirely at the full import rate rather than exported. That is the most favourable condition solar can have, and it is why leisure centres consistently rank at the top of council estate screening exercises.

Where pool heating has moved to a heat pump, electrical demand rises further and the array a site can usefully absorb grows with it. The building becomes more electricity intensive and more suited to on site generation at the same time.

Floodlighting is a winter evening load. Solar will not meet it, and any proposal implying otherwise should be treated with suspicion. The useful sequence for a floodlit site is LED conversion first, then controls and scheduling, then tariff work, and only then generation against whatever daytime load remains.

Seasonality compounds it. Pitch sports peak in the months when generation is lowest. Outdoor summer facilities peak when generation is highest but often have very little connected load to absorb it.

This is where being independent matters. If your bill is mostly floodlighting, we will say that an array is a secondary measure for your site and point you at the changes that pay back faster.

Leisure centres tend to have large, simple, single storey roofs over sports halls and pool halls, with plant concentrated in a defined area. Structurally they are usually straightforward, though pool hall roofs need care because of the corrosive internal environment and because fixings must not compromise the vapour control layer.

Stadium roofs are a different proposition. Cantilevered stand roofs carry significant wind loading and were designed to a specific load case, so structural capacity has to be confirmed for the particular structure rather than assumed. Where it works, the area available is substantial.

Car parks are the underused asset across the whole sector. Event venues in particular have large areas of hardstanding that sit empty most of the week, and a canopy there generates, shelters and provides a natural location for charge points serving visitors on event days.

Ownership in this sector is tangled. Many leisure centres are council owned but operated under contract by a trust or leisure operator, which means the party paying the electricity bill is not the party that owns the roof, and neither of them alone can authorise a twenty five year asset.

Settling that early saves months. The workable structures are council funded with the benefit reflected in the operating contract, operator funded against the remaining contract term, or a third party funded model. Clubs and community facilities periodically have access to governing body or local authority facility funds, though eligibility and timing change, so we point people at what is currently open rather than naming a scheme that may have closed.
