Building a Solar Park in 2026: From Land to Lease Agreement
A solar park does not appear overnight – and it is not built by the owner of the land either. If you own a plot that qualifies for ground-mounted photovoltaics, your role is that of the lessor: you provide the land, a project developer handles planning, permitting, construction and operation. In return, the lease typically ranges between €3,000 and €5,000 per hectare per year, depending on grid proximity and region. The most underestimated step on the way there is the grid connection request: waiting times of several months are documented, and whoever files it too late loses exactly that time. This article walks through the complete process and shows what you should pay attention to as a landowner.

Key Takeaways
Ground-mounted photovoltaics earns €3,000–5,000 lease per hectare per year, up to €5,500 at grid-near premium sites.
You build and finance nothing yourself – planning, permitting, construction and operation are handled by the project developer.
The underestimated bottleneck is the grid connection request: grid operators process in order of receipt, with a documented waiting time of ~8 months.
Very grid-near sites can earn a multiple of the solar-park lease as a battery storage (BESS) location.
What is a solar park – and what does it mean for you as the owner?
A solar park (ground-mounted photovoltaic plant) is a large, ground-mounted installation of photovoltaic modules that converts sunlight into electricity on a contiguous area – in contrast to a rooftop system on a building. For investors and energy companies, a solar park is an investment in generation capacity. For you as the landowner it is something else: a long-term change of use of your land in return for a lease payment, without you building, financing or operating anything yourself.
This separation of roles matters because it also determines what you actually have to decide. You do not need to know how an inverter works or how a grid connection is dimensioned – that is the developer's job. You do need to know whether your land is suitable at all, what a fair lease is, and which steps lie between a developer's first enquiry and the actual start of construction. That is exactly what follows.
What a solar park lease earns in 2026
Lease prices for ground-mounted photovoltaics range between €3,000 and €5,000 per hectare per year depending on grid proximity and region, up to €5,500 at grid-near premium sites. Two factors stretch this range apart:
- Grid proximity: The shorter the distance to the nearest substation or sufficiently dimensioned line, the lower the connection costs for the operator – and the more of that can be passed on to you as lease.
- Regional location: Solar irradiation, land availability and local demand for solar sites differ from region to region and influence how strongly developers compete for a plot.
Typical contract terms run around 20 years, often with extension options. You will find the current figures and tables by site quality in the guide Photovoltaic Lease Prices 2026, and details on payment terms, indexation and dismantling obligations in the guide to the Photovoltaic Lease Agreement. If you own suitable land yourself, the guide Lease Land for a Solar Park explains process, lease rates and requirements in detail.
If your land is very close to the grid, especially near a substation, a battery storage system (BESS) may be an option instead of or in addition to a solar park. The lease for that is usually considerably higher – a large-scale storage system extracts more value on a smaller area through the electricity market and grid services. Whether that is realistic for your plot is covered in the guide Leasing Land for Large-Scale Battery Storage.
The path from land to solar park: six steps
1. Area check: clarify suitability up front
Before a lease agreement is even on the table, it must be clear whether your land is fundamentally eligible. The key factors are protected areas (nature conservation, landscape protection, FFH), spatial planning (exclusion and priority zones) and rough grid proximity. You can do this step yourself before talking to a developer – more on that two sections below.
2. File the grid connection request – as early as possible
As soon as rough suitability is established, the grid connection request should be filed with the responsible grid operator. This is the step that most often comes too late, because it "feels" like it belongs after the lease agreement, when in fact it should run in parallel or even earlier. More on this in the grid connection section below.
3. Lease agreement or exclusivity agreement
Once a developer or operator is found for your land, an exclusivity agreement for the development phase usually comes first, followed later by the actual lease agreement with the final terms. The power of attorney and the grid connection request are non-binding and free of charge for you as the owner in this phase – you take on no obligation by initiating these steps.
4. Permitting procedure
Construction in outlying areas generally requires a development-plan procedure or another building permit, plus environmental assessments depending on project size. Duration and exact requirements differ by federal state and municipality. This step is the developer's responsibility, but it concerns your land – which is why milestones for it belong in the lease agreement (see below).
5. Construction and grid connection
After the permit, site preparation, mounting of the substructure and modules, cabling and finally the grid connection follow – the latter only after all safety and performance tests have been passed.
6. Operation and lease payments
From commissioning onwards, lease payments run according to the contractually agreed terms, usually annually or semi-annually. Maintenance and operation lie entirely with the operator.
Why the grid connection request is the underestimated bottleneck
The step that gets the least public attention is at the same time the one that can cost the most time: the grid connection request. Grid operators fundamentally process incoming requests in the order they are received. In a case we documented ourselves, an application for 18 MW sat at position 99 of the queue, behind requests totalling 4,753 MW – the waiting time until processing was around eight months.
For you as the owner this means: the earlier the grid request is filed, the sooner grid capacity is clarified by the time the permit is granted. If the request is only filed after the lease agreement is signed, those months run on top of the remaining project timeline – time that cannot be recovered later. Raise this actively with a developer instead of treating it as their problem alone: it is also in your interest that the process is not needlessly prolonged by a late request.
Why an area check before the first enquiry is decisive
Most providers on the market can only tell you after a manual review – often with a waiting time of days to weeks – whether your land qualifies at all. The ENLAPA Area Check checks immediately instead: protected areas, spatial planning and the rough grid situation of your land, in seconds, free of charge and without you leaving any personal data. To our knowledge it is currently the only solution on the market that delivers a true instant check instead of making you wait for a manual response.
It does not replace an in-depth technical and legal review by a project developer – but it saves you from entering talks with an obviously unsuitable plot, and for a suitable plot it gives you a solid starting point for the next steps.
Checklist: Is your land suitable for a solar park?
- Size and shape: Ground-mounted photovoltaics generally looks for contiguous areas from around one hectare upwards, practically shaped rather than elongated.
- Grid proximity: How far is it to the nearest substation or sufficiently dimensioned line? The shorter the distance, the more attractive the site and the higher the achievable lease tends to be.
- Planning status: Is the land in an outlying area? That is the case for most open spaces and is not an exclusion criterion, but it requires a permitting procedure.
- No obvious exclusion criteria: Nature conservation, landscape protection or FFH areas as well as protected biotopes often rule out use or make it considerably harder. The ENLAPA Area Check gives you a first indication.
- Current use: Low-yield arable land, conversion sites or low-yield grassland are often particularly interesting for solar parks because they less frequently compete with existing agricultural use.
If you can largely confirm these points for your land, the next step is worthwhile: make your land known and collect offers, for instance via the ENLAPA marketplace.
Lease agreement: what to look out for
A solar park lease agreement is a long-term commercial contract, usually running around 20 years with extension options. Key points that belong in it:
- An indexation clause linking the lease to the consumer price index, so it does not lose real value over the term.
- A secured dismantling obligation – the operator must fully dismantle the plant after the contract ends and restore the land to its original condition, ideally secured by a bond.
- Milestones for permitting and start of construction, combined with a special termination right if they are not met – so your land is not blocked indefinitely if a project stalls.
- Clear rules on cost coverage (notary, land register, surveying) by the lessee.
A detailed discussion of all contract points can be found in the guide to the Photovoltaic Lease Agreement.
Battery storage (BESS) as an alternative?
Not every plot is primarily interesting for a solar park. If your land is very close to a substation or a high-voltage line, a battery storage system (BESS) can be the economically more attractive option – the lease there is usually well above that of a solar park. Whether that is realistic for your land is shown in the overview Lease Land for Battery Storage.
Conclusion
A solar park comes about in a clearly structured process with separate roles: the developer plans, permits, builds and operates – you provide the land and receive a lease of €3,000 to €5,000 per hectare per year in return. The biggest lever you hold yourself is time: an early grid connection request and a reliable first assessment of your land save months.
