Shares and bonds

We will be carrying out regular community share issues over the coming years and may also raise bond finance. As with other community energy projects, we will be offering different kinds of return on investment:

Environmental: we are a carbon-first initiative and our primary concern is to fight the climate crisis. By joining and supporting the Big Solar Co-op you will in most cases be making a larger contribution to decarbonisation than you could by investing in solar at home.

Social: you will be joining an organisation that is bringing a new model to solar, involving many more people directly in practical action. Our panels will reduce energy bills for a range of sites, from industrial users to public buildings. We’re working to bring co-operatively-owned solar to places which are less sunny and less wealthy, with all our surplus re-invested in solar.

Financial: Our interest rates will be competitive and your investment in Big Solar Co-op is designed to  be flexible so it is easier to get your money out if you need it. Shares in the Big Solar Co-op are exempt from Inheritance Tax so you can pass on your membership without penalty.

Our project pipeline

Our first three sites have signed exclusivity agreements with us and we are finalising legal agreements with them now with a view to installing in late 2022. Hot on their heels is a significant pipeline of other solar sites across the UK.

Our track record

The Big Solar Co-op has been developed by Sharenergy who will also administer the share and bond offers. Sharenergy has a fantastic track record in community share offers. 

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 – get involved!
