Why hasn’t every big roof got solar?
In an energy and climate crisis, it just doesn’t make sense
The Big Solar Co-op is a not-for-profit, carbon-first and people-powered organisation.
We’re solarising commercial and community buildings all over the UK from doctors surgeries to factories and everything in between.
We’re powered by support from members of the public. Over 1000 people have invested with us and over 100 give their time as volunteers.
Investing in solar
You could invest with us from £100 and get a fair return while getting new solar built.
