Photovoltaic Lease Agreement: Step by Step to a Secure Contract

More and more property owners are asking themselves: "What do I need to watch out for in a photovoltaic lease agreement?" This step-by-step guide is aimed at landowners – whether farmers, private individuals, or companies – who want to use their land for photovoltaics. From the initial suitability assessment through legal requirements to contract conclusion, we'll guide you through the process. Learn which permits are required, what income you can expect, and how to find reputable project developers. For the overall picture of suitability, lease rates and process, see the guide Lease Land for a Solar Park; this article is about the contract itself.

Step 1: Check Land Suitability

First and foremost, you should clarify whether your property is fundamentally suitable for a ground-mounted photovoltaic system. The following questions are important:

• Location and Solar Radiation: Ideal are open, unshaded areas with good solar radiation (south-facing is advantageous). Slopes should preferably be oriented towards the south; a north-facing slope is unsuitable.

• Size: Is a solar park worthwhile? Investors typically look for areas of 5 hectares or more (for EEG-subsidized projects) or ≥10 hectares (for subsidy-free PPA projects). Smaller areas can be interesting for Agri-PV, especially near farms, but are rarely economical.

• Grid Connection: How far is it to the nearest power line or suitable grid connection point (substation)? A distance of a few hundred meters is ideal; longer cable routes increase costs. If your property is very remote without connection possibilities, it becomes more difficult.

• Current Use and Soil Conditions: Is it arable land, grassland, or a conversion area (e.g., former landfill)? Areas with low agricultural yield or fallow areas are particularly suitable, as there are fewer usage conflicts.

Tip: Use digital tools for an initial assessment. With our online area check, you can check for free in seconds whether your property meets the basic requirements (size, proximity to grid, etc.). You'll receive an immediate initial assessment and can then plan specifically.

Step 2: Clarify Legal Framework

If the location factors are positive, the legal requirements need to be checked. In Germany, large ground-mounted photovoltaic systems are subject to building planning law and often the EEG (Renewable Energy Act). You should consider the following:

• Inner vs. Outer Areas: If your property lies within a development plan (building land/commercial area), PV use is usually permitted unless it contradicts the plan. However, most large areas are located in outer areas (§35 BauGB). There, solar parks are only privileged permissible under certain conditions, namely along highways and railway lines within a 200m corridor. Outside such zones, a project-related development plan by the municipality is usually needed to enable a solar park.

• Land Use Plan and Municipality: Seek early dialogue with your municipality. The establishment or amendment of a development plan is done by the municipal council. Many municipalities are open to PV projects – also because they can now be financially involved – but there is also resistance (keyword "citizen protests" or concerns about landscape appearance). If the municipality does not give consent, a project can hardly be realized. Therefore, clarify: Does your project fit into local planning? Are there already priority areas for PV in your region?

• Permits: A building permit is required for constructing the system, usually issued by the county or city. This typically requires a valid development plan or the aforementioned privileged status. During the approval process, nature conservation aspects are also checked – e.g., reports on species protection issues (breeding birds, protected biotopes, etc.) are needed. Monument protection or water protection law may also be relevant if your property is located in such an area. A grid connection request to the local grid operator is also part of the development.

• EEG Auction vs. Direct Marketing: Clarify (possibly with the project developer) whether your area falls under EEG funding. Until 2022, for example, arable land was only eligible for funding if it was in the 200m strip along highways/railways or specially designated by federal states. Meanwhile, there are also special auctions for disadvantaged areas and agro-photovoltaics. If your property is not EEG-eligible, a solar park can still be operated economically via a PPA (power purchase agreement) – this usually requires somewhat larger projects (>10 ha). The exact path depends on the project conception proposed by the developer.

• Leaseability and Ownership: Ensure that you are actually authorized to lease. Do you own the property entirely? Are there any encumbrances (e.g., hereditary building rights, easements) that prevent this? For leased agricultural land, you need to discuss with the current operator if you want to use the area for PV – notice periods of the existing lease agreement may need to be considered.

Good to know: In many cases, the project developer handles all coordination with authorities. Your main task as owner is then to provide the necessary approvals (e.g., signature for building applications as property owner). Nevertheless, you should know the framework conditions to make informed decisions. Comprehensive advice from a specialized lawyer or the Chamber of Agriculture can be very valuable.

Step 3: Evaluate Economics and Alternatives

Before finally deciding to lease to a solar company, make a financial comparison: What returns does PV leasing bring compared to alternative uses of your land?

• Solar Lease Income: As described in the article Leasing Land for Photovoltaics, annual leases for solar parks currently range mostly from 3,500–4,000 € per hectare (depending on region and project size). This income is passive – you don't have to do anything else once the contract is running. In many cases, lease payments are indexed or slightly adjusted every few years to remain stable after inflation. Over 20–30 years, this adds up to considerable sums.

• Agricultural Use: If you farm your land yourself or lease it to farmers, the returns are significantly lower. Agricultural lease often yields only a few hundred euros per hectare annually. Even with profitable arable farming, net profits beyond 1,000 €/ha are rare, especially when considering labor and risks (weather, market prices). A farmer from Rheinhessen reports that developers in his region offer 3,000–4,000 € lease/ha – "as a farmer, I can't pay that much to my lessors". This statement gets to the heart of the difference.

• Alternatives: Are there other options for your property? For example, battery storage – however, suitable locations are rare and leases even higher, but battery storage isn't feasible everywhere and must be built as close as possible to a substation. Sale as building land could theoretically bring high returns, but most agricultural areas aren't easily converted into building areas. Own operation of a PV system: Some farmers consider investing in PV themselves (e.g., via citizen solar park). However, this requires capital and entrepreneurial commitment. For most owners, leasing to a professional operator is the risk-free and plannable way.

Note: Leasing for photovoltaics usually offers the highest financial return per hectare compared to all other common uses. You transform a previously perhaps moderately profitable area into a 20- to 30-year source of income. Of course, besides money, you should also consider idealistic factors – e.g., the loss of lease land for local farmers or changes in the landscape. But many owners conclude that the benefits outweigh: economically and ecologically.

For orientation, the following (simplified) example calculation can serve:

The financial potential of solar leasing is obviously substantial. Nevertheless, don't just look at the euro amount – ensure the overall package is right. This includes, above all, a reliable contract partner.

Step 4: Find and Select a Reputable Project Developer

Perhaps the most important step is finding an experienced and reputable project developer or solar park operator to implement your project. There are numerous players in the German market – from large, internationally active companies to smaller, regional developers. What should you look for?

• References and Experience: Ask the potential partner which solar parks they have already realized. Reference projects in your region are a good sign. A developer who has been successfully building and operating systems for years has the necessary know-how. Look at company websites for case studies or talk to municipalities where parks have already been implemented.

• Financial Stability: Building a solar park costs several million euros. Make sure the developer is financially solid – either through a strong equity base or secured investors in the background. In conversation, pay attention to whether realistic timelines and commitments are made. If you're promised the moon (e.g., "guaranteed 8,000 € lease/ha" or similar), be skeptical.

• Transparency and Communication: A reliable developer will disclose how the process works, which permits are needed, and what support they need from you. Pay attention to whether they listen to you and consider your interests. Professional providers often offer to handle all steps – from planning through permits to construction – and keep you regularly informed. A good sign is when a fixed contact person is named and your questions are answered.

• Contractual Fairness: Ask to see a non-binding contract draft. Serious developers have nothing to hide. Pay attention to the previously mentioned important contract clauses (term, lease, dismantling, etc.). Be suspicious if, for example, you're asked to reserve the area exclusively for several years without compensation in case of failure. Unfortunately, there are also unscrupulous intermediaries who collect area options en masse hoping to resell them profitably – if no investor comes, the owner is left hanging. Protect yourself by agreeing clear conditions for the development phase (e.g., annual minimum lease until construction occurs).

• Local Roots: It can be a plus if the project developer is regionally anchored or at least knows the local conditions well. They will then be more likely to deal trustfully with the municipality and residents (keyword information events, citizen participation). However, supra-regional companies are often very professional too – project experience is more decisive.

How do you find such developers? Use platforms like Enlapa to obtain free and non-binding lease offers. You can advertise your area there and receive offers from verified solar companies. This has the advantage that you have comparison options and aren't dependent on just one interested party. Alternatively, you can research yourself: Through industry associations (e.g., German Solar Industry Association) or state energy agencies, you often get lists of contacts. Municipalities often know which companies are active in the area. You can also find a compact overview of the requirements and process on our page if you want to lease your land for photovoltaics.

Take your time with the selection. Contract negotiations should never be signed hastily. Ideally, get legal advice before committing. A good project developer will understand this – after all, it's about a decades-long partnership.

Step 5: Contract Negotiation and Conclusion

Having found a suitable partner, it's time for detailed negotiations and contract conclusion. We've already explained many important contract aspects in the first article (see "Contract Design" section above). Here we summarize the steps to signature:

1. Letter of Intent / Preliminary Contract: Often, a preliminary contract or Letter of Intent (LoI) is first concluded. In this, both sides declare the intention to conclude a lease agreement, and basic conditions are recorded (e.g., lease price, area, exclusive negotiation phase). Make sure you don't bind yourself unnecessarily long if the partner doesn't deliver.

2. Review Contract Draft: The developer will present a lease contract draft that regulates all points – from term through payments to dismantling. Review this draft carefully! Ideally, consult a lawyer or knowledgeable advisor (e.g., from the farmers' association). Ensure all verbal commitments are recorded in writing. Typical points: annual lease and payment mode, indexing, contract duration and extensions, rights and obligations during planning and construction phase, liability issues, dismantling clause, land register entry, compensation for delays, regulations for early termination (e.g., if permission is denied) etc.

3. Negotiation: Don't hesitate to demand improvements. A large part of the conditions is negotiable – especially the lease itself, but also special services. For example, you can try to negotiate a one-time lease if you prefer that, or a share in the yield. Also, a contractual linkage to electricity prices in later years can make sense, as mentioned before. Good developers show willingness to negotiate within certain ranges. Stay realistic but represent your interests. Remember: The first version of a contract will often be formulated by the developer in their favor; a fair balance is achieved through negotiation. ENLAPA supports you in this, as we already demand good conditions for you.

4. Conclusion: When both sides agree, the contract is signed. Often, additionally, a land easement is agreed upon, which is notarized and entered in the land register – this is usually handled by the investor who also bears the notary costs. With the signature, your area is officially transferred for use for the solar system (often initially subject to the project being approved and built within a certain period). Congratulations – you've done it!

After contract conclusion, the project developer begins with the final planning steps, tenders for construction services, etc. As lessor, you can now relax – but remain available for any queries or coordination, e.g., regarding access during the construction phase.

Step 6: Project Implementation and Operating Phase

The actual work is now taken over by the project developer. Typically, it proceeds like this:

• Planning and Approval Phase: If no development plan exists yet, it is now established by the municipality (in coordination with the developer, who provides the necessary documents). In parallel, the expert reports are prepared (environmental impact assessment, species protection assessment, etc.), applications are submitted, and finally the building permit is obtained. This phase can take 1-3 years, depending on the initial situation. As owner, you mainly need to bring patience here. Important: During this time, depending on contract design, you may receive a small basic lease or compensation, or payments may only begin with commissioning. This should be clearly regulated in the contract (see reservation premium above).

• Construction of the Solar System: After all permits and awards are granted (e.g., when participating in an EEG auction), construction begins. The developer now coordinates the EPC companies (Engineering, Procurement, Construction). Building a medium-sized solar park usually takes only a few months. Module tables are set up, modules mounted, inverters and cabling installed and connected to the grid. During this phase, you as owner are hardly burdened – you may be informed when construction crews enter your area so you know. You incur no costs; any field damage should be remedied or compensated by the operator.

• Commissioning and Operating Phase: Once the solar park is completed, official commissioning takes place (often there's a symbolic ceremony with press photo, to which you'll also be invited). From this point on, electricity flows into the grid – and now the lease payments also flow according to contract. Note when you can expect the first payment (e.g., "30 days after grid connection" or quarterly from commissioning). Check that payments are made in correct amounts. During the operating phase itself, you have little to do. The operator takes care of maintenance, monitoring, and any repairs. As lessor, you can thus enjoy decades of income without further effort.

• Ongoing Communication: It doesn't hurt to maintain some contact with the operator. Reputable operators occasionally inform lessors about special events (repowering, changes in operations management, etc.). For larger concerns, you know who to contact – ideally, the contact person named in the contract remains available. Some owners take on tasks like maintaining green spaces for payment, as mentioned above. Such synergists can further improve cooperation.

• Contract End / Follow-up Use: Although it's decades away, one day the contract end approaches. Already some years before, you should discuss with the operator: Is there interest in a contract extension? Or will dismantling proceed as planned? In the latter case, you should ensure the dismantling obligation is met. Usually, the operator will recycle or reuse dismantled material. After dismantling, your area can be used agriculturally again – possibly soil improvement or reseeding is needed. Alternatively, as mentioned, you could take over the system if agreed, and continue operating it or transfer it to a new operator.

At the end of this process stands ideally a successful solar lease that benefits all sides: You as owner through long-term income, the project developer through a profitable project, the municipality through business taxes or participations, the environment through CO₂-free electricity, and even local agriculture if, for example, sheep graze under the modules or flower meadows develop.

Summary and Next Steps

Leasing property for solar systems may seem complex at first glance, but it can be organized in clear steps:

1. Suitability Check: Check the basic suitability of your area (size, location, sun, grid). Use tools like the Enlapa Area Check; which sites qualify at all is covered in the overview Lease Land for a Solar Park.

2. Framework Conditions: Learn about the legal requirements in your municipality and clarify which permits are needed. Seek dialogue with the municipality.

3. Economic Assessment: Compare the expected solar lease with your area's current returns. Usually, solar leasing is financially very advantageous.

4. Find Project Developer: Contact reputable solar project developers or use platforms like ENLAPA to obtain lease offers. Look for experience, transparency, and fair conditions.

5. Negotiate Contract: Take time and check the lease contract carefully. Agree on appropriate lease, clear terms, dismantling, and secure your interests contractually.

6. Support Implementation: After contract conclusion, relax while the project developer obtains permits and builds the solar park. Be available for queries, you don't need to do more.

7. Enjoy: Once the system is operational, you regularly receive your lease. Your property now works for you and generates green energy.

If you follow these steps, you're on the best path to successful solar leasing. Many owners in Germany have already taken this path – you too can use the opportunity to make more of your land. For questions or further information, we at Enlapa are happy to help.
