Solar panel lease for business
How a commercial solar lease works, what it costs, and how it stacks up against owning the system — without the domestic "rent-a-roof" baggage.
The two kinds of commercial solar lease
"Solar panel lease" covers two distinct products, and the difference matters for your accounts and tax:
- Finance lease — the asset sits on your balance sheet, the lessor owns it and normally claims the capital allowances (reflecting the benefit in lower rentals), and VAT is spread across the rentals rather than paid up front.
- Operating lease — the lowest monthly outlay, rentals are a fully deductible operating cost, and the lessor keeps the residual-value risk. From January 2026, revised FRS 102 brings most of these on balance sheet too.
What a solar lease costs
A lease is quoted as a rental, not a capital price, driven by system size, term and covenant. The number to focus on isn't the rental in isolation but whether it sits below the energy the system saves and earns — on most commercial sites it does, which is what makes a lease cash-flow positive. We always show the total cost across the term alongside a cash-purchase comparison so the convenience of a lease is priced transparently. Try it on the finance calculator.
End of term — and getting out early
Commercial leases are built to end cleanly: continue on a nominal secondary rental, return the system, or buy it at an agreed value. That's a world away from the domestic "rent-a-roof" deals of the 2010s that complicated house sales and mortgages — commercial agreements set out the exit and buy-out options up front. Mid-term exit means settling the remaining rentals, so we make sure that's clear before you sign.
Lease vs own — the honest comparison
A lease is attractive for the lowest monthly cost and spread VAT. But if your business is profitable and can use the tax relief, owning the system through hire purchase or an equipment loan usually wins over the asset's life, because the capital allowances and the export income stay with you. And neither leasing nor owning should be confused with a PPA, where a third party keeps both. We model every route so you choose with the full picture.

Solar panel lease FAQs
How do leased solar panels work for a business?
On a commercial solar lease a funder owns the system and your business pays a regular rental to use it, keeping all the electricity it generates. There are two types: a finance lease (on your balance sheet, lessor usually claims the capital allowances and prices the benefit into lower rentals) and an operating lease (lowest monthly cost, rentals fully deductible). At the end you can usually continue on a low secondary rental, hand it back, or in some structures buy it.
How much does a solar panel lease cost?
A commercial lease is priced as a monthly rental rather than a capital sum, set by the system size, the term (typically 3–10 years) and your covenant strength. The test that matters is whether the rental sits below the energy the system saves — on most commercial projects it does, making the lease cash-flow positive. We show the total cost over the term against paying cash so you can see what the convenience costs.
Can you get out of a solar panel lease?
Commercial leases are designed to be exited cleanly at the end of the primary term — continue on a peppercorn secondary rental, return the system, or buy it. Mid-term exit is possible but usually means settling the outstanding rentals, so it's priced in. This is very different from the domestic "rent-a-roof" leases that caused mortgage and sale headaches — we structure commercial agreements so the exit options are clear from the start.
Is it worth buying out a solar lease?
It can be. Buying out converts you from a renter into the owner, so you capture the residual value and stop paying rentals — and if you buy the system you may then be able to claim capital allowances going forward, depending on the structure. Whether it's worth it turns on the buy-out price versus the remaining rentals and value. We can model a buy-out, often funded by hire purchase or a loan, against continuing the lease.
Should I lease or buy solar panels?
If owning the asset and claiming the tax relief matters, hire purchase or an equipment loan usually beats a lease, because the allowances and export income stay with you. A lease wins when you want the lowest monthly cost, want to spread the VAT, or can't make use of the allowances (for example a non-taxpaying body). We model both, plus cash and a PPA, from your numbers.
