Why doesn’t every big roof have solar? The Big Solar Co-op is on a mission to solarise the UK, one rooftop at a time. We have an always-open rolling share offer to finance our ambitious program of new installations on big rooftops across the UK. We’ve now got over 40 new sites signed up and ready to build, from children’s nurseries to steelworks, leisure centres to historic buildings – we just need more members to invest so we can deliver these and focus on the next round (already coming thick and fast).

A few key facts:

• Big Solar Co-op’s focus is on solar that’s not getting built but needs to be – large rooftops, small ground-mount (on appropriate sites)
• Our target interest rate is 5% (or 2% above base rate where that’s higher)
• We’re committed to make it as easy as possible for members to withdraw capital when they need to
• You can opt to reinvest your interest (to help build more solar – and so your returns are more like compound interest in a bank)
• We have a very strong ethical policy – we pay a significant premium for our low-carbon solar panels that don’t source raw materials from areas implicated in forced labour

Whether or not you invest, you could join us – we are majority-owned by our Volunteer Members who pay £1 for membership. We can train you to find, design, and deliver solar. Do you have a favourite local big roof? Work with other volunteers from across the UK to make it happen – we’ve already helped several people to make this happen in their communities, sometimes in places that don’t have existing community energy groups.
