Caravan Park Solar Payback: How Seasonal Trade Changes It

Energy is now one of the largest controllable costs on a UK holiday park after staffing, and on most sites the site-wide bill has risen sharply since 2021. That single pressure is why so many owners are pricing up solar panels for caravan parks this year. This guide sets out what an install actually costs in 2026, why the seasonal nature of a park makes the payback maths different from a year-round business, and where the money comes back. All figures below are illustrative and depend entirely on your park, your load profile and your tariff.

What solar panels for caravan parks cost in 2026

A single static caravan park project typically lands between £45,000 and £450,000 fully installed, and the range is wide because parks vary enormously in size and in how much roof and ground they have to work with. A small amenity block or campsite system in the 20 to 150 kW band tends to start around £22,000 to £135,000. A mid-sized park with a clubhouse and a couple of amenity blocks sits in the middle. A larger park with an indoor heated pool and a full leisure complex, sized somewhere between 200 and 500 kW, reaches £180,000 to £450,000. Multi-park group roll-outs run into the millions. For the full ladder, see the guide to caravan park solar panel cost.

On a cost-per-kW basis, systems above 100 kW are typically £750 to £950 per kW, and that falls toward £600 per kW once you pass 1 MW, which is why group roll-outs across several parks achieve better unit economics than a single site can. A static caravan park system usually works out at 50 to 500 kW, which is roughly 90 to 920 panels spread across about 300 to 3,000 square metres of roof, normally the amenity blocks, reception, shop and any leisure building, with static-caravan roofs hosting micro-arrays only where ground or roof space is genuinely tight.

The headline price is only ever part of the story, though. What matters is how quickly that capital comes back, and for a holiday park that depends almost entirely on one thing: how much of the power you generate you use on site during your trading season.

Why a park’s payback is different: the seasonal load curve

Most commercial solar payback calculators assume a steady year-round demand. A holiday park does not work like that, and the difference is the whole point. A park’s demand is concentrated from April to October, and that is precisely when solar generates most. So the alignment between peak occupancy and peak sunshine, which owners often fear is a weakness, is actually the sector’s biggest strength.

When a coastal park is running 80% occupancy in August, the showers, the swimming pool plant, the bar and kitchen refrigeration and the guest EV chargers are all working hardest in the middle of the day, exactly when the panels produce the most. In-season self-consumption is therefore naturally very high, and self-consumption is the single biggest driver of solar payback. Where a 24/7 factory has to export a chunk of its generation cheaply, a well-sized park consumes most of what it makes during the months that earn the income.

In the quiet October to March stretch, when a Welsh coastal park might run 5% occupancy, the system simply exports the surplus to the grid under the Smart Export Guarantee, earning income on power you would not have used anyway. This is why a park should never be sized from a generic profile. The starting point is at least twelve months of half-hourly site meter data overlaid with the occupancy calendar, sized to the peak-season daytime baseload of the highest-value loads first: pool plant, shower-block hot water, kitchen and bar refrigeration, and increasingly guest EV charging.

Typical payback by park type

Across the sector, payback typically runs between 5.5 and 7 years. The variation tracks the load profile:

Parks with a swimming pool or leisure complex

These have the fastest payback, around 5.5 years. The pool plant (pumps, heating and dehumidification) is the single biggest electrical load on most large parks, and it runs hardest in the same months solar generates most. Pool heating plus solar is one of the fastest-payback combinations anywhere in UK leisure.

Static caravan and holiday-home parks

A typical payback near 6 years, driven by the steady summer baseload from pitch pillars, reception, shop, laundry and lighting, plus any amenity-block hot water.

Lodge and glamping parks

Around 6.5 years. Premium lodges with hot tubs are high per-unit electricity users, and hot-tub heating is a significant load that runs across much of the year.

Touring and camping sites

Toward 7 years, where the dominant loads are shower-block hot water and lighting on lower-capital amenity-block systems.

Where the money comes back

Capital cost is only one side of the ledger. The biggest single lever in the numbers is tax relief. The panels, inverters, mounting and battery storage all count as plant and machinery, so up to the £1m annual cap the 100% Annual Investment Allowance lets most park businesses set the cost against year-one profit, returning as much as a quarter of the project value in tax to a limited company. There is a point owners often miss here: as a special-rate asset, solar is excluded from full expensing, yet the 100% AIA still relieves it in full, and a single-park install almost always lands inside the cap. Above the cap, the 50% First Year Allowance applies to the balance, which mainly affects larger multi-park roll-outs. The detail sits with HMRC under capital allowances.

Alongside the tax relief, the Smart Export Guarantee pays for the off-season surplus, with tariffs around 12-13p per kWh for the better open fixed rates in October 2026, with small suppliers paying 3-6p. Because each supplier sets its own rate, it is worth shopping around. Our grants and funding guide covers the export tariff, EV charging support and the funding routes in detail.

Funding without using your reserves

Few parks fund a solar install from cash, and seasonal cash flow means most do not want to. A power purchase agreement delivers day-one savings against your current tariff with zero capital outlay, which suits a business that earns the bulk of its income in six months. Asset finance spreads the cost over 7 to 15 years and is typically positive against EBITDA from the first year. For groups, a single finance framework lets every park draw on the same facility.

Working out your own numbers

The honest answer to “what will it cost us” is that it depends on your roof, your loads and your occupancy calendar, which is exactly why a quote should be modelled from real meter data rather than a template.
