At Celtic Green Energy, we are one of Wales’ leading commercial energy experts, offering a consultative approach to help businesses reduce rising energy costs and transition to sustainable energy solutions.

Own your solar PV system from day one. Start saving immediately on energy bills, with typical payback in 3–4 years and over 25 years of free electricity after that.
Prefer to preserve your cash? Finance your solar installation with no upfront cost, using your monthly energy savings to cover repayments — keeping you cashflow positive from day one.
For larger commercial systems, our funding partners can finance the system. You simply purchase the clean electricity you generate — at a lower rate than your current energy provider.
