Community solar anywhere

The Big Solar Co-op is a new approach to subsidy-free community solar, supported by Sharenergy. We’re working across the UK to:

  • Make solar viable on a huge range of sites – without subsidy
  • Empower and support volunteers to work together to get it built
  • Fight the climate crisis through large-scale, grassroots community action
