We’re people powered

We’ve raised over £2m to date from more than 1000 supporters from all over the UK.
They’re members of the public investing from £100 and getting a fair annual return on their investment.
Now we’ve launched our first ever bond offer, to raise the funds to build our new Whiteborough Solar Park.

A ground-breaking solar project
It’s not every day you get to turn a former coal mine into a solar park.
But that’s exactly what we are doing at Whiteborough in Nottinghamshire.
It’s our largest project to date, using ethically-sourced solar panels and even reusing some older (but perfectly good) solar panels which would otherwise be broken down and recycled.
Our bond offer
One great thing about our bonds is that they can be wrapped in an ISA, meaning the interest you earn is tax-free. There’s a fixed interest rate of 5.5% annually, and the bond capital will be repaid after 7 years.
To carry out the bond offer we’ve partnered with ethical finance specialists Ethex – all the details are on their website.

If you’d prefer to support our work by buying shares, our rolling share offer remains open. By buying a share you become a member and get a say in the way we run but your interest payments are not fixed or tax-free
There’s more information about our share offer and a comparison of shares and bonds on our shares page.
More than one type of return
However you choose to invest, we offer different kinds of return on investment:

Environmental
We are a carbon-first initiative. By supporting the Big Solar Co-op you could be doing more for decarbonisation than by investing in solar at home.

We’re lowering energy bills for commmunity sites and local businesses -often in places which are less sunny and less wealthy, with all our surplus re-invested in solar.

Financial
We aim to offer a fair return on your investment. Our interest rates are competitive and tax-efficient.
Invest your time
The Big Solar Co-op has been created from the ground up to enable volunteers to be more effective in fighting the climate crisis. So if you have any time to spare, there are lots of things we can do together, within a supportive and effective organisation.
