Is Solar Worth It for Holiday & Caravan Parks?

It is a fair question, and one every holiday park owner should ask before spending six figures. Solar panels for caravan parks are not automatically the right call for every site, but for a great many UK holiday parks, caravan parks and campsites the case is unusually strong, and stronger than it first appears. This guide gives an honest answer: where solar genuinely pays, where it needs care, and the handful of situations where it might not be worth it yet. The figures throughout are illustrative and depend on your park, your loads and your tariff.

The objection that turns out to be the strength

The first thing most owners say is some version of “our demand is all in summer, so won’t the panels sit idle for half the year?” It is the obvious worry, and it is exactly backwards.

A park’s demand is concentrated from April to October, and that is precisely when solar generates the most. So the alignment between peak occupancy and peak sunshine is the distinctive hook for this sector rather than a problem to work around. 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 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 exports a chunk of its generation cheaply, a well-sized park consumes most of what it makes during the months that earn the income.

The off-season takes care of itself too. In the quiet October to March stretch, when a Welsh coastal park might run 5% occupancy, the system exports its surplus to the grid under the Smart Export Guarantee, earning income on power you would not have used anyway. So the half of the year that worries owners is the half that quietly generates export revenue.

Where solar is clearly worth it

Parks with a swimming pool or leisure complex

If your park has an indoor or outdoor pool, the answer is almost certainly yes. Pool pumps, heating and dehumidification are the single biggest electrical load on most large parks, and they run hardest in the same months solar generates most. Pool heating plus solar is one of the fastest-payback combinations in UK leisure, typically around 5.5 years. Bars, restaurants and entertainment venues add heavy refrigeration and lighting loads in season, and those large, mostly flat leisure-building roofs make ideal PV surfaces.

Parks adding guest EV charging

Around 59% of larger parks now offer EV charging, and guests increasingly expect it. The problem is that grid-supplied charging is expensive and can overload ageing site infrastructure. Pairing chargepoints with on-site solar absorbs daytime generation at close to 100% self-consumption, and adding battery storage lets you charge cars from stored solar into the evening peak without overloading your DNO supply. That often defers or avoids an expensive grid upgrade, and the OZEV Workplace Charging Scheme can fund up to 75% of the chargepoint cost. If EV charging is on your roadmap, solar makes it dramatically more affordable to run.

Off-grid and rural touring or glamping sites

This is where solar can be transformative rather than merely sensible. Many touring and glamping sites are rural, with weak or no three-phase supply. Rather than paying for an expensive DNO grid extension to a remote field, a solar-and-battery micro-system can power shower blocks, lighting, pods and hot tubs directly. The economics here are not “save a bit on the bill”, they are “avoid a five-figure grid connection and an 18-month wait altogether”. On a genuinely off-grid site, solar-plus-battery frequently wins outright against a grid extension.

Parks chasing green credentials and bookings

Eco-conscious guests, especially in the glamping and premium-lodge segments, actively choose greener parks, and Green Tourism awards now influence OTA visibility and direct bookings. On-site solar is auditable evidence behind a Green Tourism Gold award, and several parks now display live-generation dashboards in reception as a guest talking point. If sustainability is part of your marketing, solar gives you something real to point at.

Where it needs care, but usually still works

National Parks, AONBs and coastal settings

Planning needs more thought in protected landscapes, but it is very achievable. Rooftop PV on reception, amenity and leisure buildings is the least intrusive option and often falls under permitted development. Where ground-mount is needed, discreet, screened arrays with a proper visual-impact and landscape assessment, and early engagement with the planning or National Park authority, carry the day. Many parks in protected settings already run solar successfully, so a sensitive setting is a reason to plan carefully, not a reason to give up.

Ageing site electrics

Many parks have ageing pitch pillars, amenity-block boards or incoming supplies that should be brought up to current BS 7671 Section 708 standard. That is not a reason to avoid solar, it is a reason to combine the two. A full condition survey gives you one coordinated plan, and the upgrade can usually be funded inside the same capital envelope as the PV rather than as a separate job.

Capacity-constrained grids

Rural and coastal parks frequently sit on constrained DNO networks, where a G99 export connection can take 6 to 18 months. The answer is to submit the application early and, where export capacity is tight, design for self-consumption only or add battery storage so the project is not held hostage to the grid queue.

Where it might not be worth it yet

In the interest of an honest answer, solar is harder to justify in a few cases. A park with almost no daytime load even in season, no pool, minimal amenity buildings and no plan for EV charging, will see weaker self-consumption and a slower return. A site operating under a short seasonal or limited-period planning licence may not have the security of tenure to justify owned capital, though a PPA can sometimes still work. And a park already facing a major roof replacement should usually do the roof first, or combine the two, rather than mount panels on a structure that needs work. In each of these cases the right move is to model it properly rather than assume, because the numbers occasionally say “not yet”.

Funding makes “worth it” easier to reach

Part of what makes solar worth it for so many parks is that it rarely needs to come from cash. A power purchase agreement delivers day-one savings with zero capital outlay, which suits seasonal cash flow. Asset finance spreads the cost over 7 to 15 years and is typically positive against EBITDA from year one. On top of that, the 100% Annual Investment Allowance returns as much as a quarter of the project value in year-one tax relief for a limited company, and the Smart Export Guarantee pays for off-season export. Together those routes bring the “worth it” threshold a lot closer than the sticker price suggests.

The honest bottom line

For most UK holiday and caravan parks, especially those with a pool, EV charging plans, or an off-grid touring or glamping element, solar is worth it, and the seasonal match that owners worry about is the very thing that makes it pay. The exceptions are real but narrow. The only way to know which side of the line your park sits on is to model your actual half-hourly meter data against your occupancy calendar, which is what we do before recommending anything.
