Nations back global rooftop solar push at COP31 talks
Five countries have endorsed a new declaration at the COP31 climate talks in Turkey aiming to double global rooftop solar installations by 2030.
Key points
- Five countries including Nigeria, Australia, Bangladesh, Kenya and Vanuatu backed the voluntary Global Rooftop Solar Declaration.
- The initiative aims to increase homes with rooftop solar from 150 million to 300 million by 2030.
- Experts emphasize that national policies, grid upgrades and storage funding must follow the non-binding pledge.
What happened
A coalition of nations has formally endorsed the Global Rooftop Solar Declaration during the COP31 climate talks held in Antalya, Turkey. The Boston Herald reported that Australia, Bangladesh, Kenya, Nigeria and Vanuatu signed the pact on Tuesday, aiming to expand household solar capacity worldwide over the coming years.
The initiative targets doubling the number of residential rooftops equipped with solar panels from approximately 150 million to at least 300 million by 2030. Lawmakers from 21 additional nations, alongside Indonesia's state-owned electric power company, have also supported the voluntary framework.
Proponents argue that decentralized solar generation offers households protection against volatile energy prices. Sonia Dunlop of the Global Solar Council noted that the measure provides a practical mechanism to help working people manage rising living costs and energy shocks.
Implementation challenges
Industry analysts have cautioned that voluntary pledges require robust domestic frameworks to deliver meaningful reductions in carbon emissions. Bruce Douglas of the Global Renewables Alliance stressed that national policies must accompany international declarations.
Observers point out that rapid renewable deployment often outpaces grid capacity and storage infrastructure. Without adequate investments in battery storage and transmission networks, power systems face operational difficulties and generation curtailment.
Why it matters
For energy investors and policymakers across Africa, expanding decentralized solar generation presents both an opportunity and a regulatory challenge. While off-grid and rooftop solutions can improve energy access in regions constrained by centralized transmission limitations, financing consumer subsidies and managing grid integration remain critical hurdles. With global oil benchmarks such as Brent trading at 107.03 US dollars per barrel and diesel at 4.525 US dollars per gallon as of November 2026, according to US EIA data, consumers face intense cost pressures. Leveraging decentralized renewables can mitigate these economic burdens, provided that African governments establish clear frameworks for equipment standards, consumer financing and installer certification.

Context from CEII
Renewables are the fastest-growing part of the world’s energy system. The COP28 goal is to triple capacity by 2030, and solar mini-grids are the fastest route to power for millions of people without electricity.
