We’ve made it simple to join us – here’s the deal:

You can join us by buying shares – any amount from £100 to £100,000

You can opt to receive annual interest payments or reinvest your interest, so we can roll out more solar, faster

We aim to pay a fair rate of interest: Bank of England base rate plus 2% – our target annual rate is currently 6.25%

Did we mention our bond offer?

Alongside our share offer we also currently have a live bond offer to raise funds for our ground-breaking Whiteborough Solar Park. Our bonds offer fixed 5.5% annual interest over 7 years and can be wrapped in an ISA – so your income would be tax free.

We’re carrying out our bond offer in partnership with Ethex, the leading ethical investment platform.

WHAT MAKES US DIFFERENT?

We are people powered

We’re owned by our members who provide us with the cash we need to build solar. Many of them also give hours of volunteer time as solar champions in their neighbourhoods.

We break down barriers

We break down financial barriers for businesses and community buildings to go solar. We install panels at no cost to the host site and sell them energy at discounted rates, often saving them hundreds of thousands of pounds.

We’re motivated by solar delivered, not profit margins

Unlike big energy companies, we’re owned and governed by our members and we use the best and most ethical solar technology available. As a co-op we can’t be bought or sold. After our members get a fair return, any surplus goes into building more solar.

Funding Communities

Community buildings and small businesses are the heart and soul of local areas. We slash their energy bills, freeing up funds for them to do what they do best. We’re on a mission to deliver brighter futures for local areas.
