Funding options
Three ways to fund commercial solar
UK businesses can fund commercial solar through capital purchase (CapEx), a Power Purchase Agreement (PPA) or a lease. Each model suits different financial situations.
Capital Purchase
You buy the system. You own it. Full savings from day one. Typical payback: 4–7 years.
Power Purchase Agreement (PPA)
A funding partner installs the system at no cost to you. You buy the electricity at a discounted rate. No ownership, no maintenance.
Lease / Hire Purchase
Spread the cost over a fixed period. Own the system at the end of the term.
For a detailed breakdown of each funding route, read our Commercial Solar Funding Guide.
Process
How a PPA works
A Power Purchase Agreement lets a business install commercial solar at zero upfront cost. A funding partner finances, installs and maintains the system, and you buy the electricity at a discounted rate. Learn more in our Solar PPA Guide.

Frequently asked questions
A PPA is a long-term contract where a funding partner finances, installs and maintains a solar system on your property at no upfront cost. You buy the electricity at a pre-agreed rate lower than grid price. The funder owns the system for the contract term, usually 15 to 25 years.
