Commercial rooftop solar · UK
Lower energy costs. No upfront capital.
Your roof.Our investment.Your savings.
Green Energi develops, funds and manages rooftop solar installations for UK businesses and commercial property owners. Eligible businesses use the electricity generated on their own premises under a long-term Power Purchase Agreement (PPA), without funding the installation upfront.
Why a funded PPA
The system is funded through the project investment structure, not paid for by your business at the outset.
A tailored PPA tariff designed to offer savings against the grid electricity you buy today.
Ownership, monitoring, insurance and maintenance are arranged through the project owner.
Rooftop solar can support your ESG and energy reporting objectives.
How it works
We look at your site, roof and electricity consumption, ideally 12 months of half-hourly data.
Array layout, forecast generation, on-site consumption, PPA pricing and forecast savings.
Grid application, landlord consent and approvals, then installation by an appointed contractor.
Monitoring, maintenance, insurance and billing for the solar electricity you use.
You pay for the solar electricity you use, through an invoice at your agreed PPA rate.
PPA rates and savings depend on consumption, generation, installation cost, credit assessment, term and site factors. Typical project screening begins around 50 kWp, subject to eligibility.Who we work with
Use lower-cost solar electricity generated on your own premises, with no installation capex.
Turn unused roof space into a better offer for tenants, through a tenant PPA or a landlord-led structure.
You install. We structure, fund and manage. Sites from around 50 kWp may be considered.

Questions
Under a qualifying fully funded PPA, the installation is funded through the project financing arrangement, not paid for upfront by the customer.
Many commercial solar PPAs run for 20–25 years. However, when Green Energi partners with a commercial landlord, we may be able to offer an electricity offtaker (the tenant or occupier) a PPA term as short as five years. Availability depends on the landlord partnership structure, tenant requirements, site economics, credit assessment and agreed contractual terms.
Some of our PPAs include a pre-agreed option to buy the solar installation. Depending on the site, the electricity savings achieved may help fund a buyback in approximately six to eight years. Timing and price are specific to the agreement, and there is no guaranteed payback date.
The project owner arranges insurance for its solar equipment. The building owner retains separate insurance obligations. Longer-term PPAs are subject to an appropriate credit assessment.
Rooftop solar may contribute positively to a building’s EPC assessment, but the outcome depends on the building and the applicable methodology. We can explore this during feasibility.
Assignment, early termination, roof access, removal and reinstatement rights are governed by the signed PPA and property agreements.
