Five nations endorse target to double rooftop solar homes by 2030

At COP31, Australia and several countries endorsed the Global Rooftop Solar Declaration, which seeks to double the number of homes with rooftop solar from about 150 million to 300 million by 2030. Endorsers named in reports include Bangladesh, Kenya, Nigeria, Vanuatu and Palau; Indonesia’s state-owned utility and lawmakers from 21 countries also backed the effort. The voluntary pledge calls for governments to expand financing, make rooftop solar a priority in energy plans, modernize grids and develop local installation and maintenance workforces. Solar advocates say rooftop panels and home batteries can improve energy security and shield households from volatile fossil-fuel prices, while experts caution that the target will require concrete national policies and support for solar systems and batteries.
