Commercial Solar Solutions
We have multiple funding options available for Commercial Solar Solutions. These include Outright Purchase, Fully Funded Solar PPA and Finance.
We will help you find the right option for your business
Fully Funded Solar PPA
A fully funded Solar Power Purchase Agreement (PPA) provides a risk-free path to green energy by eliminating all upfront capital investment and ongoing maintenance. Through this arrangement, a third-party provider installs and manages the system, allowing you to purchase electricity at a significantly reduced rate—often 30% to 50% lower than standard grid prices—providing immediate protection against energy price volatility. Most agreements offer a path to ownership for a nominal fee at the end of the 10–25 year term.
Outright Purchase
Outright Purchase gives you 100% of the energy generated by your solar system. This is the best option if you have large amounts of capital to fund the purchase. Outright Purchase also offers some tax advantages.
Finance
Solar Finance makes solar energy accessible with little or no upfront cost, spreading the large equipment purchase and installation cost into manageable monthly payments.
Fully Funded Solar PPA
A fully funded solar Power Purchase Agreement (PPA) allows UK businesses to install solar panels with zero upfront capital investment, as a third-party provider designs, funds, and maintains the system for the duration of the contract (typically 10–25 years).
The primary “pro” is immediate energy cost reduction, as you purchase the generated electricity at a fixed or inflation-indexed rate—often 30% to 50% lower than standard grid prices—while the provider remains responsible for all maintenance, insurance, and performance risks.
However, the “cons” include a lack of immediate asset ownership and the inability to claim UK tax incentives like the Annual Investment Allowance (AIA) or Full Expensing, as the system belongs to the funder.
Furthermore, while most PPAs transfer ownership to the business for a nominal fee (often £1) at the end of the term, you are committed to a long-term legal agreement that can complicate property sales or relocations if the new occupant is unwilling to take over the contract.
Outright Purchase
Owning a solar panel system outright offers significant benefits, including long-term financial savings and environmental advantages, but it requires a substantial initial investment.
Once installed, you generate your own electricity, significantly or even eliminating your monthly energy bills. The Smart Export Guarantee (SEG) in the UK allows you to sell any surplus energy back to the national grid and get paid for it.
Commercial properties with solar panels genuinely sell for more and can be more attractive to potential buyers.
The primary drawback is the significant initial investment required for purchasing and installing the system. It can take up to 10 years to recoup the initial installation costs through energy savings and export payments. Owning a solar panel system outright also means you are responsible for maintenance, faults and breakdown repair.
Finance
Financing commercial solar in the UK allows businesses to install panels with zero upfront capital, preserving cash flow while utilising immediate energy savings to often cover the monthly loan repayments from day one.
In the 2026 tax landscape, a significant “pro” is that most UK businesses can still claim 100% tax relief in the first year via the Annual Investment Allowance (AIA) or Full Expensing, even when the system is financed, effectively reducing the net cost by up to 25% (at the current corporation tax rate). Furthermore, you retain full ownership of the system, meaning you keep all income from the Smart Export Guarantee (SEG) for surplus power.
The “cons” include the added cost of interest (typically 8% to 13% APR), which slightly extends the payback period compared to a cash purchase, and the fact that, unlike a Power Purchase Agreement (PPA), the business is responsible for all ongoing maintenance and performance risks.
If your site has a decent sized roof or land space with good sun exposure, and you’re using electricity during the day then the answer is probably yes. Solar is ideal for offices, schools, warehouses, factories, farms and more.
There is no one size fits all price, costs depend on system requirements and the type of equipment used.
Yes, with landlord permission, as long as the lease runs for the duration of any agreement.
Most commercial buildings have enough space, from flat roofs to ground mounts, systems can be adapted to your needs.
Installation can range from a few days to a few weeks, with the whole process from enquiry to operation in under 3 months.
Solar only generates power during daylight hours; storage batteries can be added for night-time energy usage.
Panels degrade very slowly, between 0.1% and 0.5% per year. They often maintain 80-90% efficiency even after 25 years.
Panels need to be clean for optimal output, although rain often suffices, regular cleaning of panels is recommended. All elements of the solar system need to be regularly monitored to ensure optimal performance.
SEG pays for exported excess energy. Tax relief is also available through some purchase options.
Some systems may fall under permitted developments. Your appointed installer will handle all compliance issues including planning permission.
