Ethex Cuppa Club
Thursday 3 July 2025, 11:45 – 12:30

Join us for a special online discussion between Ben Sharpe, Senior Investment Manager at Ethex, and Jon Halle, as they explore how ethical investment can drive a sustainable energy future. Timed to coincide with the launch of Big Solar Co-op’s new bond offer on Ethex, this event is a chance to hear first-hand about the organisation’s ambitious plans to scale up community-owned solar energy across the UK.
We’ll look at the Whiteborough solar park, the next major project to be funded by this new bond offer, and explore the bigger picture of how community investment is unlocking the vast potential of solar power across the UK. This discussion will also highlight Big Solar Co-op’s commitment to sustainability and ethics—from pioneering the reuse of second-life solar panels, to ensuring all new panels are responsibly sourced, and carefully selecting sites to protect biodiversity and food security.
The Big Solar Co-op offer to solar host sites
Tuesday 8 July, 12:30 – 13:30 (on Zoom)
Do you own or run a community or commercial building? You could reduce carbon emissions while making a long-term saving on electricity costs.
How it works…
We install, own and manage the panels and there is no capital cost to you.
We sell you clean, renewable power from the roof for less than you are currently paying for grid electricity – usually much less. The Big Solar Co-op is a good partner – we are ethical and open, supported by existing coops with an excellent track record. We will analyse your roof and tell you if it is viable for solar through us, with no obligation and no hard sell. Our bottom line is to reduce carbon emissions, not to make profits. There’s more detail on our process and legal agreements pages.
Join this call with our Client Lead, Dean Hill to find out more.
