Top 3 Ways to Fund Commercial Solar Projects | Geo Green Power

Transitioning to renewable energy is a significant strategic investment, and our team is here to help UK businesses navigate the complex landscape of government grants and private finance.  

As a nationwide leader in large-scale solar installations, we do not provide the financing ourselves; instead, we act as your strategic partner to bridge the gap between your energy goals and the capital required.  

We work with government bodies and specialist private lenders to help you identify and access the most effective funding routes, dramatically reducing capital expenditure and accelerating your return on investment.

Strategic Financial Incentives: Tax Relief & Funding

The UK government incentivises the shift to net-zero through direct grants and powerful tax mechanisms. Whether you are an SME or a high-energy industrial site, our team provides the technical guidance and expertise needed to help you leverage every available pound. While we are not a finance provider and do not manage your capital directly, we can equip you with the data, insights, and industry connections to navigate the funding landscape effectively. 

Annual Investment Allowance (AIA): Deduct 100% of the cost of your solar installation (up to £1 million) from pre-tax profits in the first year. For many, this acts as a 25% cash-back on the investment. 

50% First-Year Allowance (FYA): Multi-million-pound projects exceeding the AIA claim an immediate 50% deduction on “special rate assets” like solar panels. 

Business Rates Exemption: Under current 2026 regulations, most new rooftop solar installations are exempt from business rates until 2035

Regional Grants (e.g., BEAS): Depending on your location and business size. and type, you may be able to access government grants that provide full, part, or match funding for the costs of energy-saving measures.

Power Purchase Agreements (PPA) & Solar Leasing

Power Purchase Agreements (PPA): Ideal for businesses that prefer not to manage an energy asset. A funder pays for the installation and maintenance; you simply buy the generated electricity at a fixed rate significantly lower than the grid.

Solar Leasing: Secure a solar PV installation at a fixed monthly cost, benefit from all the energy that it generates, but don’t pay the full cost of installation or have transfer of ownership.

Funding Commercial Solar: FAQs

What are the main ways to fund a commercial solar installation?
Commercial solar projects can be funded by using either capital expediture (capex), Power Purchase Agreements (PPAs), Asset Finance or Grants. New funding models are developed all the time so using a combinations of funding methods is a possibility.
What is a Power Purchase Agreement and how does it work?
A Power Purchase Agreement or PPA, is an agreement between a customer, and a PPA fund. The PPA cover the cost of the solar installation on behalf of the customer, and then sub-meter the electric back to the customer. This rate allows the PPA fund to charge a small levy for the use of the electric, however it is still lower that the customers current electricity tariff.
Can we install solar panels with no upfront cost?
Yes! Power Purchase Agreements are the best funding model for this. Asset Finance will allow you to purchase solar, but you would have to pay a deposit, usually the VAT, currently 20%,m and then a rate as agreed with your lender.
What is the difference between asset finance and a PPA?
Technically quite a lot. Both allow you to purchase solar without a significant upfront cost. But the main difference are - asset finance means you will own the solar once the finance arrangement has ended, but for a PPA, the PPA fund effectively own the solar - but you will have options once the term has finished.
What are the benefits of using capex over finance options?
The big benefit is that you own the system, and reap the full financial benefits from day one. Payback is often within five years, so for the majority of businesses - solar is a very effective, solid investment.
Are there any Government grants or incentives for commercial solar energy?
Local councils often provide grants, schemes and subsidies, but it is best to speak to your local council. You can also look at the Ofgem website which provides advice and information.
Is solar finance available to all business types?
Yes it is, both private and public sector businesses can utilise commercial solar funding options. Speak to our team to find out how we can help.
How do I know which funding option is right for my business?
Give us a call! If you contact us on info@geogreenpower.com or call 0800 988 3188 - we will be able to guide you through the options. We are not a financial institution however so cannot provide financial advice, but we will provide sound information on all current solar funding options.
Does using finance affect ownership of the solar system?
Yes, sometimes. Generally, if you opt for PPA, then the solar is owned by the PPA fund. If you choose asset finance, then you will have ownership.
What happens at the end of the finance or PPA term?
For finance you will have paid your last installment, and the system will be yours, with you receiving the full benefits. The end of a PPA term will depend on the specific agreement, but you usually have the option to purchase the system at a reduced rate.
