Not sure what to consider before leasing land for a solar farm? Join us as we review everything you need to know to create a watertight contract for your solar project.

Signing any legal contract is a big commitment and when you’re signing a lease that can run for up to 40 years, you certainly don’t want to go in with your eyes closed. But what exactly should you look for when leasing land for a solar farm? Well, we’re here to tell you exactly that.

Over the years, we’ve seen hundreds of lease agreements that have good (and inherently bad) clauses. So, we decided to share our knowledge and give you everything you need to know before signing on the dotted line. From option agreements and mid-lease options to income considerations and monitoring plans, this guide has it all.

You’ll move into the option agreement phase after a developer bookmarks your land as suitable for solar development.

Option agreements usually run for around five years, but they can stretch further than this if planning permission or Grid connection is particularly complicated or challenging to get.

The option agreement “reserves” your land for a solar project and allows your developer to get going with the following things:

  • Feasibility studies
  • Getting planning permission
  • Getting grid connection
  • Financing the project
  • Securing necessary supplies to get the project moving

Your land will be tied up and reserved exclusively for the developer during the option period. So, you won’t be able to alter your land significantly during this period. It’s important to understand that an option agreement doesn’t necessarily mean a project will come to fruition. It’s just the first step towards the project.

We also want to mention that what is contained within the option agreement will largely follow through into the final lease with minimal variations being possible. Therefore it’s important to make sure that key terms are ironed out at this stage of the project. Otherwise, you could face issues with the project further down the line (and not be able to do much about them).

You’ll get a fixed fee for reserving your land, but you may need to seek out another developer if the original option agreement falls through. However, if your site is unviable, your land may not be suitable for a solar project altogether.


Once the option agreement is signed, your developer may discuss the possibility of a Power Purchase Agreement (PPA).

Developers are usually quite secretive about these as they’re often considered commercially confidential. However, developers often keep their PPAs quiet because many landowners use a fixed payment arrangement for the project.

And if the landowner has no share in the site’s output (and the income that comes with it), there’s technically no reason to share this information freely.

If you can, it’s always worth discussing a royalty-based payment arrangement (if you’re happy with a small amount of risk). This way, you’ll have insight into the PPAs and are more likely to earn more if the project performs well. If relevant, by knowing about the PPA in place, landowners can better understand the payments owed to them.


We advise landowners to get ahead of the game when planning leases, as it’s less likely to lead to panicked decisions. Realistically, the more time you have to discuss your lease terms, the better the terms will be. If you rush to meet a deadline, you may agree to terms that aren’t financially sound (at least for you).

Being prepared and putting your best foot forward here is critical, and that’s because you’ll be locked into a lease for around 35-40 years. That’s a long time if you’re not entirely happy with the terms. If you don’t get your ducks in a row before getting to the negotiating table, you’ll feel pressured, unprepared, and in a poor position.

If possible, try and do the following things before negotiating a lease:

  • Carry out plenty of market research to figure out the worth of your site
  • Understand the terms presented to you by consulting experts in the field
  • Carefully comb through the lease agreement and raise any terms that are unclear 
  • Ask your developer for previous examples of their work and how financially viable these sites are

As mentioned in the previous section, you should conduct serious market research before leasing land for a solar farm. The ideal land for a solar farm will have plenty of sunlight, flat surfaces, and enough space to house hundreds or thousands of panels. So, if you have all of these things going for your site, you’ll be in a great position to negotiate and get what your land is worth.

Developers willy try to make as large a profit as they can. So, they’ll often flick through their current portfolio and may land on a rate that they think is reasonable but under current market rates. Many developers aren’t up-to-date on the going rates across the country, so it’s always important to counter with accurate figures.

You might be tempted to agree to poorer financial terms if you’re unaware of the going rates for similar sites nationwide. But if you have solid facts and figures to show that the land is worth more and what comparable sites are earning, you’ll want to use these to your advantage.

Before signing any legal document, you should get help from a team of experts with your best interests at heart. While we understand that expert advice can be costly, taking on a solar farm lease isn’t something you want to do lightly.

Solicitors, land agents, and accountants should be your first port of call. But solicitors are especially useful as they’ll help you pick out any unclear terms in your lease (and explain them, too). Solicitors may even request additions (or suggest them) that may improve the overall terms of the lease agreement.

On the other hand, land agents will help you apply for necessary permissions, agree terms with site operators, and help set up timetables for decommissioning. They can also help you set up timelines for extending the project if that’s what you’d prefer.

Lastly. accountants are essential if you want to determine the financial viability of a project. They can review any existing financial data from the developer.

All in all, leasing land for a solar farm is far easier with a few helping hands in tow.


If you weren’t aware, there’s a major backlog for securing grid connections for new projects. This can sometimes be as long as ten years, with most new projects getting green-lit for 2030 and beyond. Because of these backlogs, most developers will choose to go ahead without Grid connection in place (in the hopes that they’ll get it eventually). The same goes for planning permission, which can take a long time to secure for most large-scale projects.

If you’re worried about how long these processes take, checking in with your developer is always a good idea. Any developer worth their salt should be willing to check on these timelines for you and offer peace of mind.

A mid-lease option is a clause in a contract that allows landowners to renegotiate terms part-way through a lease. Despite its name, it doesn’t always happen at the mid-point of a lease and can fall at any time after the contract has started.

If you’re wondering why this is a good option, it’s because it gives you a chance to look at the following things:

  • Current market rates
  • Expected rental income
  • Cost of living

If any of the things above have altered over time, the mid-lease option allows you to renegotiate. After all, a lot can change across 40 years, and you’ll want to ensure you’re getting fairly compensated.

And if you’re consistently doing market research on other sites around the country, you’ll be in a great place to boost your rental payments.

If you’re in a place that’s recognised as suitable for solar development, you may already have projects near your land.

If there’s an operational solar farm near you, there are a few benefits here:

  • You’ll know that planning permission may be easier to get (as it’s already been approved for a project close by)
  • You’ll be surer about a project reaching completion, giving you the confidence to get started
  • There may already be a Grid connection point nearby

Your neighbours will only be allowed to share some high-level information about leasing their land for a solar farm, as it’s confidential. But if you can get an idea of how much the process impacts them daily, you’ll be in a good position to make a decision.

For most landowners, income considerations constitute a significant part of any project (and it’s often a driving force). So, it’s essential to carefully consider the rate you’re offered and the payment arrangement you’re interested in.

Fixed arrangements are incredibly popular with solar projects as they use the acreage of your land multiplied by an average rate. However, you should discuss a royalty-based payment arrangement if you want to boost your earnings and take on slightly more risk. If this interests you, hybrid arrangements or turnover-based payments will be more suitable.

Whatever you choose, you’ll want to ensure you’ve carefully weighed up the risks and rewards of each option before signing.

As your land is your livelihood, you should consider a project’s impact on your land. Solar panels take up a lot of space, and your site is likely to take a slight beating from construction vehicles, maintenance, and machinery.

For this reason, it’s crucial to get a clause baked into your lease that includes plans to return your land to its original state. This will help you avoid nasty disputes and give you peace of mind as you sign your property away for several years.


We understand that landowners need to be able to carry out their day-to-day activities as far as possible. After all, the solar farm payments are unlikely to be your sole source of income (especially if you’re a farmer). But while a project is being built, a lot of land will simply be out of commission. This will be down to construction work, setting up relevant maintenance tech, and everything in between.

It’s essential to check in with your developer on projected timescales to keep yourself abreast of what’s going on. This will help you manage your expectations from the option phase to the maintenance and monitoring stages.


Once the site is up and running, the developer will manage it directly or hand it over to a site operator. The latter is more likely for large-scale developers with many projects to handle. For starters, you’ll want to know who you’ll deal with daily, as a great relationship is critical to a successful project. It’s also important to determine your responsibilities as a landowner and how you can help keep the project running smoothly.

For example, can you:

  • Help maintain the grounds?
  • Report any broken equipment to the site operator?

Although they’re small things, keeping the project fully functioning is in your best interest. The longer a site is down for maintenance, the less output it will create. Over time, that could significantly impact your bottom line.

Most solar farm agreements won’t require landowners to sign over every acre of their land. However, you DO want a clear idea of what land your developer needs to include in the initial agreement. This way, there won’t be any issues with your developer/site operator.

Depending on your job as a landowner, you’ll also want to double-check your rights for crop cultivation, rearing livestock, and generally existing on your property during the lease’s life. If you do this, you’ll know which parts of land are free to use and which the developer has reserved for the solar project.

Just be aware that there may be some restrictions on your land as solar projects take up a lot of space. It won’t be a dealbreaker, but you’ll want to prepare to have this land bookmarked for up to 40 years.

You want to be aware of exit strategies if you’re leasing your land for a solar farm. Closing down a project is expensive, and you must check on your developer’s plans for decommissioning and GET THESE IN WRITING before signing a lease.

Most developers will set aside money for decommissioning (as it’s often par for the course), but these plans should be in your contract from Day One.

You want to add this to your lease because it’s technically the landowner’s responsibility to return the land to its original state. So, make sure your developer lays out decommissioning plans and leaves no onus on you as the landowner to set things straight later.


Most site operators and developers will want to maintain their Grid connection as it’s a precious asset. But as the technical owner of the land, you may be able to take this back for yourself if you want to. if you can write Grid connection ownership into your lease during initial discussions, that’s ideal.


Before signing your lease, it’s essential to opt OUT of sections 24-28 of the Landlord and Tenant Act 1954. If you don’t opt out, you’ll have minimal power over the tenancy when the lease ends. If you opt-out, you can choose exactly what happens to your land once the lease ends. Otherwise, it’ll automatically renew, and your site operator won’t have to vacate.

We understand that signing a lease for 40 years (or more) will feel daunting. But with forward planning, help from experts, and secure knowledge about current market rates, you can’t go wrong. Remember to leave plenty of time for the negotiation phase, as you won’t want to rush your decision. At the end of the day, it’s always a great idea to prepare yourself and come to the table armed with cold, hard facts.
