More than one type of return
We are 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 can 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 are reducing 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 are 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.
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!
