Protect working capital
Asset finance or a PPA can reduce the capital needed at the start, leaving funds available for stock, equipment, recruitment or other business priorities.
Commercial solar finance for UK businesses
Compare outright purchase, asset finance and Power Purchase Agreements for commercial solar panels. We model each option against your site's energy use, ownership plans and cash-flow priorities so you can make an informed decision.
Why consider finance for commercial solar panels?
Commercial solar finance can turn an eligible, well-designed project into a planned operating decision rather than a single capital purchase. The right structure depends on ownership, contract terms and what the system is expected to save—not finance alone.
Match cost to savings
A structured payment term can spread the cost while the system generates electricity. The forecast should compare payments and savings year by year.
Choose your ownership
Buy for control and long-term value, finance toward ownership, or use a PPA where a third party owns and maintains the system under contract.
Plan tax treatment
Ownership and funding structure can affect capital allowances and accounting treatment. Confirm the position with your accountant before proceeding.
Make a measured choice
Good commercial solar finance starts with energy data, site suitability and realistic assumptions—not a headline rate viewed in isolation.

Compare commercial solar finance options
There is no universally best model. Compare control, total lifetime cost, responsibilities and exit provisions alongside the initial payment.
| Consideration | Outright purchase | Asset finance | Power Purchase Agreement |
|---|---|---|---|
| Initial payment | Full purchase price | Deposit or initial rental may apply | Usually no system purchase cost |
| System owner | Your business from purchase | Depends on agreement; often transfers after final payment | Third-party funder during the term |
| Typical agreement | No finance term | Often structured over several years | Long-term electricity purchase contract |
| Electricity benefit | All avoided grid cost and eligible export income | Benefits support repayments, subject to agreement | Electricity bought at the contracted PPA tariff |
| Maintenance | Your responsibility | Usually your responsibility | Commonly included to the contracted scope |
| Tax and accounts | Capital allowances may apply | Depends on agreement and accounting treatment | Provider owns the asset; treatment requires advice |
| Best suited to | Businesses with capital seeking maximum ownership benefit | Businesses wanting ownership with staged payments | Businesses prioritising low initial capital commitment |
Terms vary by provider and agreement. Asset finance and PPA availability is subject to eligibility, site assessment, contract terms and credit approval. Obtain accounting, tax and legal advice where appropriate.
How each commercial solar funding route works
The same solar design can produce different commercial outcomes depending on who owns the equipment, who receives the electricity benefit and what happens at the end of the agreement.
Purchase or asset finance
- Outright purchase gives your business immediate control of the system and its generation.
- Asset finance spreads agreed payments across a fixed term and may lead to ownership, depending on the contract.
- Your business will usually arrange maintenance, monitoring and insurance under either route.
- Capital allowance and accounting treatment should be confirmed for the chosen agreement.
Power Purchase Agreement
- A third party funds and owns the equipment installed on your site.
- Your business buys the solar electricity at the contracted tariff for the agreed term.
- Maintenance and monitoring are commonly included, but the service scope must be checked.
- Tariff increases, minimum terms, property changes and end-of-term options should be reviewed carefully.

Illustrative solar finance cash-flow example
A finance proposal should show the relationship between electricity savings and repayments. This simplified example demonstrates the calculation; it is not a quotation or forecast for your business.
| Example item | Illustrative figure | What to check |
|---|---|---|
| Forecast solar electricity used on site | 80,000 kWh | Depends on your demand profile and system yield |
| Illustrative avoided grid price | 24p/kWh | Use the tariff and non-commodity charges relevant to your bills |
| Illustrative annual electricity saving | £19,200 | 80,000 kWh × £0.24 |
| Illustrative annual finance payments | £15,600 | Example only; lender terms, fees and credit approval vary |
| Illustrative annual position | +£3,600 | Before maintenance, insurance, tax and other project-specific costs |
Illustrative example only. It excludes export income and assumes every stated unit is generated and used as modelled. Actual generation, consumption, tariffs, payments, fees, maintenance, insurance, tax and savings will vary. Finance is subject to contract and credit approval.
UK tax allowances and export income
Tax relief and export payments can support a solar investment case, but neither should be treated as automatic. Confirm eligibility, ownership and rates using current information before committing.
Annual Investment Allowance
Qualifying expenditure on plant and machinery may be eligible for Annual Investment Allowance under the tax rules in force when the business incurs the cost. Available relief depends on the purchaser, ownership structure, timing and the business's circumstances. A PPA differs because the site occupier does not normally own the solar asset. Ask your accountant to confirm how the proposed route applies to you.
Smart Export Guarantee
Eligible small-scale low-carbon generators may be paid for electricity exported to the grid through a supplier's Smart Export Guarantee tariff. Rates and contract conditions vary, and larger commercial systems or some ownership structures may use other export arrangements. The proposal should state who receives export income and avoid assuming exported electricity is worth the same as electricity used on site.
Commercial solar finance checklist
Before choosing commercial solar finance, check the complete project and contract—not only the monthly payment or advertised electricity rate.
Energy profile
Use recent bills and half-hourly data to test generation, self-consumption and export assumptions across the year.
Property and roof
Confirm ownership or landlord consent, remaining lease term, roof condition and who pays if reroofing is needed.
Credit and security
Understand eligibility checks, guarantees, deposits, security requirements, fees and what happens after a payment default.
Contract and exit
Review price increases, early settlement, transfer, change of occupier, buyout, removal and end-of-term provisions.
Operations
Check maintenance, monitoring, insurance, access rights, performance responsibilities and response times in writing.
Future plans
Account for expansion, electric vehicles, battery storage, business relocation and expected changes in operating hours.

Start with the site, then choose the finance
A poor site does not become a good solar project because finance is available. We first establish whether the building or land, grid connection and electricity demand support a sensible design. Finance options can then be compared against the same technical and savings model.
This gives decision-makers a consistent basis for comparing capital purchase, funded ownership and a PPA, while making assumptions and responsibilities visible before contracts are signed.
Accreditations
Horizon Commercial Solar is fully accredited and MCS certified. Every installation meets the highest standards for design, safety and performance.
Frequently asked questions
How can I finance commercial solar panels?
The main routes are outright purchase, commercial asset finance and a Power Purchase Agreement (PPA). Purchase normally offers the greatest long-term benefit but needs available capital. Asset finance spreads the system cost over an agreed term. A PPA can avoid the system purchase cost because a third party owns the installation and sells the generated electricity to your business under contract.
What is a commercial solar Power Purchase Agreement?
Under a PPA, a funder owns the solar system installed at your premises and your business agrees to buy the electricity it generates at the price and for the term set out in the contract. The provider will usually be responsible for agreed maintenance and performance obligations. Review the tariff indexation, minimum purchase terms, end-of-term options and property provisions carefully before committing.
Can my business claim tax relief on commercial solar panels?
Qualifying solar equipment purchased by a business may be eligible for capital allowances, including Annual Investment Allowance, subject to the tax rules and your circumstances at the time of purchase. The relief available can depend on ownership, finance structure and available allowance. Ask your accountant or tax adviser to confirm eligibility and timing before using tax relief in an investment decision.
Will commercial solar finance be cash-flow positive from day one?
It can be, but it is not automatic. The answer depends on the system yield, the proportion of solar electricity used on site, your avoided grid tariff, finance payment, fees and any export income. We compare forecast savings with the proposed payment schedule so you can see the expected annual position and the assumptions behind it.
Can I finance solar panels on leased commercial premises?
Potentially, but you will normally need the landlord's consent and must review the remaining lease term, repair obligations and rights of access. The finance or PPA provider may also require agreements covering a sale, change of tenant or early lease termination. Resolve these points before detailed design and credit approval.
What happens if my business moves or sells the property?
An owned system would normally form part of the property transaction unless agreed otherwise. Asset finance and PPA contracts may allow transfer, early settlement or another route, but conditions and charges vary. Ask for these provisions in writing and consider your likely occupancy period before selecting a finance model.
Who maintains a financed commercial solar system?
With an outright purchase or many asset finance arrangements, the business is responsible for maintenance, monitoring and insurance. A PPA provider will commonly retain agreed maintenance responsibilities because it owns the system. Check exactly what is included, response times, performance reporting and exclusions in the proposed contract.
Can a financed solar system earn export income?
Surplus electricity may be eligible for an export tariff where the installation, metering and supplier arrangement meet the relevant requirements. Who receives that income depends on system ownership and the finance contract. On-site use is often more valuable than export because it replaces purchased electricity, so system design should prioritise your demand profile.
Can commercial solar finance be repaid early?
Some asset finance agreements permit early settlement, while others include minimum terms or settlement charges. PPA buyout provisions vary by provider and stage of the contract. Request a clear schedule of early-exit, transfer and end-of-term options before signing and take independent legal or financial advice where appropriate.
