Via South China Morning Post, a look at China's massive 'distributed' solar power generation program on roofs of houses, factories and airports is spreading across country, but curtailment rate is also rising:.
A major push to install rooftop solar panels on Chinese buildings is putting the nation on track for another record-setting year on renewable energy.
Just this week, China announced it is aiming for 50 percent of new factory rooftops to sport solar installations by 2025, China Dialogue reports, as distributed solar increasingly figures into the energy plans of the world's biggest emitter.
In September, China's National Energy Bureau announced a new initiative for local governments to partner with solar developers to build rooftop arrays. Under the scheme, building owners can purchase solar panels and sell the power they generate to developers, or developers can lease rooftop space to install solar panels they own.
The rooftop solar programme, she added, will “no doubt help to decarbonise China's power sector and help with the energy system transition”. The programme has been hailed for the way it delivers a top-down policy in a decentralised manner.
The pilot alone could deliver installed capacity around 100GW, analysts estimate. If the policy is rolled out across the country, it could eventually reach 600GW. “China is making very impressive efforts to install solar energy,” Xing Zhang, senior analyst at the Centre for Research on Energy and Clean Air.
“The blistering growth in China's solar power installations this year is largely driven by distributed/rooftop projects,” tweeted Lauri Myllyvirta, of the Centre for Research on Energy and Clean Air, who described the policy as “ambitious and smart”.
