The bigger picture

As the climate and energy crises continue, the Big Solar Co-op is pioneering a simple and replicable solution, unlocking the massive untapped potential for solar energy across the UK—on rooftops of large buildings and unused land with grid connections that are just waiting to be powered by the sun. Since 2022, they have:

  • built and own 11 operational rooftop solar projects (totalling over 1250 kW of panels – about the same as 400 average-sized domestic rooftops) 
  •  produced over 1000 MWh of energy every year – enough for over 20 million passenger miles in an electric train
  • signed up over 40 more sites, ready to build solar on over the next 2 years, all over the UK. 
  • grown to have 1,100 members who support the co-op, including investors and volunteers. 
  •  successfully initiated and progressed the Whiteborough solar park project, built on a former open-cast coal mine
  • pioneered the re-use of solar panels in the UK, incorporating second-life panels alongside new, ethically sourced panels 

  • They have big ambitions to do much more, and this bond offer will finance the development of the new solar installation at Whiteborough.

    *IFISA eligibility depends on investors' individual tax status and current legislation.

What your money will do

Your investment in the Big Solar Co-op bond offer will 

  • Fund the completion of the Whiteborough solar project on a former coal mine, which will generate around 3,000 MWh of clean energy each year for at least 25 years
  • Help to cut carbon emissions by around 619 tonnes per annum
  • Support the re-use of solar panels and an ethical approach to solar panel sourcing, using an ethical supply chain, where possible
  • Support the Big Solar Co-op’s vision of the development of carbon-busting solar arrays on all suitable sites all over the UK
  • Provide the capital to repay the expensive short-term bridging loans used for the build stage of the Whiteborough project
