At-A-Glance Financing Comparison

Many projects achieve cash-flow positive outcomes with asset finance, where monthly bill savings exceed finance repayments. PPAs deliver immediate savings with zero capex by selling you onsite solar at a discounted rate to grid power.

Choosing the right route: quick decision guide

  • If £0 capex and guaranteed discount to grid matter most, and you want no maintenance burden:

    Pick PPA
  • If you can invest upfront and want the highest lifetime return with full control:

    Pick CapEx
  • If you want ownership but prefer savings-offset-repayments:

    Pick Asset Finance
  • If you want a fixed monthly cost today and upgrade/buy options later:

    Pick Lease

If You Don’t Own Your Building

Solar is still very achievable. Landlords gain improved EPCs and asset value, tenants gain lower running costs. Greenscape Energy routinely broker structures (PPA, lease adjustments or shared investment) so both sides win.

For tenants/landlords, we’ll structure a tri-party agreement so the economics and responsibilities are crystal-clear.

Frequently Asked Questions

01 What are the main ways to finance a commercial solar panel system?

There are four core options: Power Purchase Agreements (PPA), outright purchase (CapEx), asset finance (hire purchase or loan), and leasing. Each method has different benefits depending on your business’s cash flow, ownership goals, and appetite for long-term returns.

02 Can I install commercial solar panels with no upfront cost?

Yes. A Power Purchase Agreement (PPA) allows you to benefit from solar energy without any upfront capital. The system is installed and maintained by the funder, and you simply purchase the electricity at a discounted rate compared to your grid tariff.

03 Which is the cheapest way to finance solar for my business?

The “cheapest” option depends on your objectives. CapEx (outright purchase) delivers the highest lifetime return, while a PPA provides immediate savings without investment. Asset finance spreads costs over time, and leasing offers fixed monthly payments with flexibility.

04 How do I choose the best solar financing option for my company?

The right choice depends on your cash position, long-term strategy, and ownership preference. Businesses with available capital usually benefit most from CapEx. Companies prioritising cash conservation may prefer a PPA or asset finance. Leasing suits organisations seeking predictable, service-style arrangements.

05 How does a solar Power Purchase Agreement (PPA) work for businesses?

With a PPA, Greenscape Energy funds, owns, and maintains the solar panels. You buy the electricity they generate at a fixed, discounted rate (often up to 50% cheaper than grid power) for 10–25 years. This provides immediate bill savings without capital outlay.

06 Will a PPA price go up each year?

Most PPAs include indexation. We model the rate against your historic tariffs so you can see net savings across the entire term. Even with indexation, PPAs usually remain well below market electricity prices, if not Greenscape can be open to negotiation and it can be written into contracts.

07 What happens at the end of a solar PPA term?

At contract end, you can often buy the system outright at fair market value, extend the agreement, or request removal. This gives businesses flexibility depending on future plans.

08 Is a PPA suitable for SMEs, or only large corporations?

PPAs work for both. Any business with significant daytime electricity use can benefit, including offices, warehouses, manufacturing, and agriculture.

09 What are the benefits of buying solar panels outright?

Outright purchase (CapEx) offers the strongest long-term financial return. You own the system from day one, keep all energy savings and export revenue, and gain full control of the asset. Typical payback is 3–5 years.

10 Do commercial solar panels qualify for tax relief?

Yes. In most cases, businesses can claim capital allowances on qualifying solar equipment. Always confirm the treatment with your accountant to maximise tax efficiency.

11 How does asset finance for commercial solar work?

Asset finance spreads the cost of the solar system across monthly repayments, usually over 3–7+ years. In many cases, savings from reduced energy bills meet or exceed repayments, making the project cash-flow positive during the term.

12 Do I own the solar panels at the end of asset finance?

Yes. With hire purchase or loan structures, you typically become the system owner once the finance is fully repaid. This allows you to capture all future savings and export income.

13 Do I still save money if I lease solar panels?

Yes. Leasing replaces part of your grid spend with cheaper onsite solar. While lifetime returns may be lower than CapEx, the benefit is low upfront cost and predictable monthly budgeting.

14 What happens at the end of a solar lease?

Depending on the contract, you may choose to extend the lease, upgrade to a newer system, or purchase the panels at an agreed price.

15 Who maintains the solar system under each financing option?

With a PPA, all operation and maintenance (O&M) is included. With CapEx, asset finance, or leasing, the system is your responsibility. However, Greenscape Energy offers comprehensive service plans to protect warranties and performance.

16 Can I earn from exporting surplus electricity?

Yes, if you own the system (CapEx, asset finance, or lease with buyout). You can set up Smart Export Guarantee (SEG) or bespoke export agreements. With a PPA, export benefits remain with the system owner.

17 Can tenants and landlords both benefit from solar financing?

Yes. Greenscape Energy regularly structures tri-party agreements so tenants enjoy reduced bills while landlords gain improved EPC ratings and asset value.

18 How long are typical commercial solar finance terms?

PPA: 10–25 years

Asset Finance: 3–7+ years

Lease: 5–10+ years

CapEx: lifetime ownership (25–30 years).

19 How does solar financing impact ESG and CSR reporting?

Financing solar demonstrates a clear commitment to sustainability, helping businesses reduce carbon emissions and strengthen ESG credentials without affecting working capital.

The two technicians, Luke & Cam arrived as scheduled, were courteous and respectful. They carried out the work as requested and invited me to inspect what they had done. Luke also clarified and guided me through a particular aspect on the Solis App.

Harry fixed a persistent problem we've had for years. Over the last 4 years, a number of engineers had a go at fixing this but without success. Very happy with Harry and the knowledge he had of the Mitsubishi system

Chloe was very helpful with my winter settings, my app wasn’t the same as the written instructions but she just did it for me and then checked to see it was all working correctly.

I have used Greenscape Energy to install Solar Panels and Tesla Powerwall batteries and I can confidently state that they are an excellent company to deal with. I recently had a minor problem with the batteries not being charged during the cheap rate. Greenscape could not have been more helpful and put me in contact with Tesla to resolve the problem. Fantastic service from a professional company.

Michaela, dealt with my finance query in a professional, efficient manner, and placated my fears that the progress on my solar system would be paused until the return of the surveyor from holiday. Good customer care. Thank you

I have been very impressed with the service I received from Greenscape. The initial survey was very professionally done by Andrew and I was pleased that he convinced me not to have more panels than necessary. The team that installed the battery and inverter were excellent and very pleasant to deal with. The system is up and running and there have been no complications. I thoroughly recommend Greenscape.

I arranged to have solar panels and a battery installed by Greenscape via OVO Energy. From start to finish, the service has been excellent. From the survey, to the panel installation and battery installation, every team member has been professional and very friendly. The after sales have kept in contact to make sure everything has gone smoothly. Couldn't fault Greenscape.
