Commercial Solar Power Purchase Agreements for Welsh Businesses
Go solar with no capital outlay — we install the panels, you buy the electricity at a fixed rate below your current tariff. Day one savings, zero risk.
What Is a Solar Power Purchase Agreement?
A Power Purchase Agreement (PPA) is a long-term solar finance arrangement where Celtic Green Energy installs, owns and maintains a solar panel system on your commercial property — at no cost to your business.
In return, you agree to purchase the electricity the system generates at a fixed rate, typically 20–40% below your current grid tariff. You get immediate savings, we get a long-term energy partner.
In short: your roof generates the energy, we own the system, you pay less for your electricity — guaranteed for the duration of the agreement.
At the end of the agreement term, you can extend, renegotiate, or purchase the system outright — typically at well below market value.

Save From Day One
The moment your system is live, you start paying your lower fixed rate for solar electricity. Savings are immediate, guaranteed, and ongoing.
The Benefits of a Commercial Solar PPA
Zero Capital Outlay
No upfront investment required. Celtic Green Energy funds, installs and owns the system — you simply pay for the electricity you use at a lower rate.
Immediate Cost Reduction
From the day your system goes live you pay less per kWh than your current grid rate — typically 20–40% less, fixed for the duration of your agreement.
Fixed Rate, No Surprises
Your PPA rate is fixed and predictable. While grid energy prices rise, your solar electricity cost stays stable — protecting your business from energy price volatility.
Fully Maintained by Us
We own the system so we maintain it. All servicing, monitoring, insurance and repairs are our responsibility — zero operational burden on your team.
Meet Sustainability Targets
Reduce your Scope 2 carbon emissions, achieve sustainability KPIs, and demonstrate clean energy credentials to customers, investors and lenders.
Off Balance Sheet
A PPA is typically classified as an operating expense, not a capital liability — keeping your balance sheet clean and preserving credit lines for core business investment.

Is a Solar PPA Right for Your Business?
A commercial PPA works best for businesses with a large roof space, consistent daytime energy usage, and a desire to reduce costs without capital expenditure. Ideal sectors include:
-
Manufacturing & Industrial
High daytime energy usage and large roof areas make manufacturing sites ideal PPA candidates — often the largest savings.
-
Offices & Commercial Premises
Office buildings with consistent occupancy hours can offset a significant proportion of their energy with rooftop solar.
-
Agriculture & Rural Estates
Farm buildings with large unshaded roof space are excellent solar candidates — and PPAs free up capital for the farm itself.
-
Retail & Logistics
Warehouse and retail park roofs are often ideal for large-scale solar — and PPA agreements can cover multiple sites.
-
Healthcare & Education
NHS trusts, private healthcare and schools often use PPAs to meet sustainability targets without capital budget pressure.
