China’s buildings and rooftops have potential to host more than 1,000 GW of solar power capacity — almost the same size as the entire existing global industry, according to the sector’s largest manufacturer.
According to Zhong Baoshen, chairman of Longi Green Energy Technology Co., there is theoretically enough space on residential, commercial, and public properties to host that scale of generation capacity as costs fall and technologies advance. During peak generation, that would be enough to power at least 750 million homes.
