28th June 2024Planning to set up a solar project? Use my detailed guide to solar farm payments that will help you to maximise the value of your land.
If you’ve decided to put a solar project on your land, one of your top priorities should be understanding your solar farm payments. But how do you determine which arrangement will suit you best? In this rundown, I’ll cover four major rental types:
- Fixed
- Turnover
- Hybrid
- Multiple outputs
By providing the detailed pros and cons of each payment type, I’ll help you make an informed decision and achieve the best outcome.
Types of Solar Farm Payments for Landowners
Fixed rent
This is the most common type of payment arrangement that you’ll find in solar projects across the UK. In these cases, a landowner receives a fixed payment that doesn’t rely on how the solar farm performs.
The site operator will calculate the rent as an annual fee and increase it over time to match inflation. While it may not be the most lucrative payment arrangement, it’s the most stable option for most landowners.
Many landowners prefer to take a relatively ‘hands-off’ approach with their projects. In my opinion, this is the perfect payment arrangement if you want to have minimal involvement with the financial ins and outs of a project.
For most solar farms, fixed payments are based on an ‘acreage x rate’ model.
In short, landowners get a fixed rent for the portion of land they’re renting (measured by acreage). This arrangement is easier to understand, as most landowners know how much acreage they have to offer right off the bat.
Advantages of fixed rent payments
- You’ll get the fixed rate regardless of how well the project performs.
- The fixed rate protects you from any volatility that the solar project experiences, including output issues, inflation and poor performance.
- It’s low risk and offers high certainty, making it the perfect choice for risk-averse landowners who are new to the game.
- Landowners need to invest minimal time in checking the accuracy of their payments. The payments either match what’s agreed on their lease or they don’t.
Disadvantages of fixed rent payments
- A developer will almost always pay you less in this arrangement, as it doesn’t expose you to the same risks. With the certainty of fixed rent, you also lose out on the project’s potential boom cycles.
- You won’t know how the project is performing financially. This information is often commercially confidential if you have no real stake. This can make it more difficult to feel fully invested in the project for the 30+ years the lease runs for.
- When a lease ends, it’s much more difficult to prove the market rate for a typical solar project if you have fixed payments. Much of the income you’re looking at from similar projects may operate with turnover or hybrid rent, giving you a smaller pool of examples to pull from.
Fixed rent offers several pros and cons for landowners. But overall, it’s a stellar option if you’re happy to accept a slightly lower rental figure for guaranteed payments and more certainty.
However, if you’re more interested in maximising your income (and are happy to take a few risks), it’s unlikely to be the best fit.
Turnover
Turnover rent is entirely different from fixed rent. You’ll calculate this based on a percentage of the site operator’s income.
Sometimes, this is based on the overall turnover of the project, but the specific approach should be outlined in your lease agreement.
The site operator usually pays this rent annually or quarterly, and you’ll typically receive a higher rate than you would under a fixed rental contract.
You will have to accept more risk here, though.
While the potential rewards can be enormous, you’ll also have a vested interest in the project’s performance. If you have an excellent year, you’ll see an income boost. If you have a bad year, you could take a real hit, which you wouldn’t see with reliable, fixed rent payments.
So it’s all about weighing up the potential risks and rewards.
Advantages of turnover rent
- You’ll receive a higher rent compared to other payment methods, as you’re sharing in the financial risks of the solar project.
- You’ll have greater insight into how well (or poorly) the project performs. This not only gives you the chance to understand your project better, but you’ll be in a stronger position during contract renegotiations with an intimate knowledge of your payments.
- Receiving a percentage of the profits lets your income scale considerably as the project recoups its investment over several years.
Disadvantages of turnover rent
- 85 per cent of landowners discover calculation errors during the lifetime of their project due to the complexity of the calculations. So, if you choose turnover rent over fixed rent, you must keep careful tabs on all incoming payments.
- Some site operators might disagree with you on what is considered turnover or income. As a result, you may find unexpected deductions on your payments.
- Verifying the accuracy of your solar farm payments can be tricky, as commonly used Power Purchase Agreements (PPAs) are often commercially sensitive. Site operators may share this information with you, but getting accurate data can be time-consuming and requires serious diligence on your part.
- You’ll be exposed to any income volatility the project experiences, which could drop your rental income.
Hybrid rent
If you want your solar farm payments to mix the best of both worlds, a hybrid rental contract might be the way to go.
This payment arrangement combines fixed and turnover rent. This means you’ll usually get a fixed payment for leasing your land and a calculated proportion of the site’s turnover.
Advantages of hybrid rent
- Gives you complete visibility over your solar project. When a mid-lease option or renegotiation process rolls around, you’ll be in a great position to negotiate (as you’ll have all the financial information).
- Although there is a degree of risk here, you will be fully exposed to the financial risks of the solar project. So if there are periods with poor irradiance, cloud cover, damaged panels or anything else, you won’t suffer as much of a blow.
Disadvantages of hybrid rent
- You’ll essentially be monitoring two different payment types at any one time, making it more complicated than tracking a fixed or turnover arrangement.
- It can be tricky to get all the information you need, like PPA information or turnover details, to track the accuracy of your payments. So you might get paid less than you’re owed if anything is missed.
- If the site operator sells the electricity generated by the site for less than the market price, you could lose out. This sometimes happens with PPAs and can reduce the overall turnover of your solar site.
Generational or multiple of outputs
Although it’s not a typical payment arrangement at most solar sites, you can also consider the option of generational or multiple of outputs rent.
This involves landowners receiving rent based on the electricity a site produces. The figure is multiplied by a fixed value to give you the final rental fee.
This is a great choice if your site is set to have impressive output over the years. It is paid quarterly or annually, and like other payment arrangements, it will also increase with inflation.
Advantages of generational or multiple of outputs rent
- There’s less exposure to price volatility as payments aren’t linked to the project’s income.
- It takes little effort to check the accuracy of the payments. However, you must check that the payments are regularly increasing with inflation. It’s also essential that you have the means to double-check whether the figures given to you about energy generation are correct.
- It’s difficult to disagree with a site operator about the amount of rent due, as it’s less complex and less subjective.
- It isn’t affected by the site operator choosing to sell a PPA to an off-taker for a lower agreement than the market price.
Disadvantages of generational or multiple outputs rent
- You are more exposed to the operational risks of the project if there is any poor management. For example, the site can’t generate electricity if it’s down for an extended period. In these cases, you wouldn’t receive any payments.
- You will have less visibility over the project’s performance and will be less able to negotiate payment increases.
- Verifying the exact amount of electricity produced is tricky, as this will come directly from the site operator. So, a good relationship with them is a must.
Which Solar Farm Payments Are Best for Me?
There is no such thing as the ‘correct’ or ‘best’ payment arrangement for every landowner. That’s because each one has different priorities and appetites for risk.
Many landowners choose fixed rental payments, as solar developers are on the smaller side in the UK. Calculating a fixed rent is generally considered a less admin-heavy approach to the whole process.
Is solar the best financial option for my renewable energy project?
Some operators will pay solar landowners in royalties, but these tend to be based on megawatts (MW) or production capacity. If the payments are income-based, the solar farm will need to install a lot of capacity to match any wind farm payments.
So, a wind project may be more suitable if you’re a landowner looking to get the most bang for your buck.
Now, of course, this decision will be down to what your land has to offer. If it’s in an area with less-than-ideal wind speeds, you’ll be on to a loser here.
But it’s worth considering that you’d need to host a 20 MW solar farm to produce the same income as a 1 MW wind turbine.
So, Are Solar Farms Worth the Investment?
The comparison with wind energy doesn’t mean that solar isn’t an excellent investment. Generally, solar projects have an ROI of between 10 per cent and 20 per cent, which is nothing to scoff at.
However, allocating the sheer amount of land that developers need for a successful solar project can be difficult for any landowner.
If you have less land to spare and excellent wind speeds in your area, wind turbines may be a more lucrative option.
Need to figure out which type of renewable energy project to go with? Calculate your acreage, check solar irradiance levels in your area and assess the topography of your land.
