🗞️ Driving the news: A report from the Common Wealth thinktank proposes a universal Solar Bond scheme to remove the upfront cost of rooftop solar
• Written by Dr Donal Brown of the Environmental Change Institute and titled A Right to the Sun, it would make every household with a suitable roof eligible without credit checks
• Costs would be repaid over 25 years through energy bills, with the finance attached to the property rather than the occupier

🔭 The context: Rooftop solar could supply around 40% of Europe's electricity by 2050, according to analysis in Nature Energy, but only about 10% of European rooftops currently carry panels
• Governments have used grants and tax relief — up to €1,800 in Ireland, two-thirds of costs in Hungary, zero VAT in Germany and the Netherlands — yet installation costs remain the barrier, particularly for low-income households
• A European family home typically needs 6–15 kWp, costing €7,000 to €30,000
• The UK's Energy Savings Trust estimates at least 10 years to recoup the outlay

🌍 Why it matters for the planet: The gap between 10% of rooftops fitted today and 40% of electricity by 2050 is a financing problem, not a technical one
• Capital cost, not roof availability or panel efficiency, is what currently limits deployment, and it excludes lower-income households, concentrating the transition among those who can already afford it
• Tying repayment to the property rather than the occupier removes the mismatch between a 25-year asset and shorter household tenures, which deters installation on homes people expect to leave

⏭️ What's next: The report estimates households would save at least £83 a year net of repayments, or close to double with a battery
• It cites Solar Trade Association figures suggesting more than 42,000 jobs could be created by an expanded rollout by 2030
• The scheme remains a proposal, with no government commitment reported

💬 One quote: Delivering the programme "would also provide an opportunity to create jobs and improve livelihoods in communities across the UK" — A Right to the Sun, Common Wealth report by Dr Donal Brown

📈 One stat: Around 40% of Europe's electricity could come from rooftop solar by 2050, against roughly 10% of rooftops equipped today.
