How the Arrangement Works
The developer takes on all costs and risk
Our developer partners finance the entire project. Hardware, installation, grid connection, insurance, and ongoing maintenance are all covered by them throughout the contract. Your organisation bears no upfront expenditure and no ongoing infrastructure responsibility.
You pay only for electricity generated
Once the system is live, it supplies your building directly. You pay for the electricity it produces at your locked-in PPA rate. Your existing grid connection remains active as a backup, automatically covering anything the solar installation doesn't produce.
You are not charged for the system. You are not charged for maintenance. You pay for electricity — at a rate agreed before the contract begins.
Your rate is fixed from day one
Standard grid electricity prices fluctuate with the wholesale market. Your PPA rate does not. Whether energy prices rise or fall, your cost per unit stays predictable for the life of the agreement.
What the Contract Covers
A PPA agreement with Sunbase includes the following as standard:
- ✓Full system design and installation at zero cost to your business
- ✓All electrical connections and utility integration
- ✓Ongoing performance monitoring throughout the contract
- ✓All routine maintenance and emergency repairs
- ✓REGO certificates confirming the renewable origin of every unit generated
- ✓A fixed energy rate for the full contract duration
- ✓System ownership transferred to your organisation at the end of the term
Why Businesses Choose a PPA
Energy is one of the most unpredictable costs a business carries. A PPA removes that unpredictability without requiring capital investment or project management from your side.
For most qualifying sites, the PPA rate sits below the current grid rate from the outset. That gap tends to widen over time as wholesale prices continue to rise, meaning the financial case for a PPA typically strengthens the longer it runs.
Businesses also use PPAs to meet sustainability targets. Every unit generated on-site reduces grid dependency and comes with a verifiable certificate of renewable origin — useful for ESG reporting, procurement requirements, and net-zero commitments.
What Happens at the End of the Contract
When the agreement concludes, the solar system transfers to your ownership for a nominal £1 fee. The installation remains fully operational at that point and typically retains 10 to 15 years of remaining capacity.
From that point forward, your organisation generates electricity at virtually no cost.
Next Steps
Sunbase works with commercial and industrial properties operating systems of 50kW and above. If your site has suitable roof or ground space and a meaningful energy bill, we can provide a detailed savings projection at no cost and with no obligation to proceed.
