China is expected to overtake Germany to become the world's largest generator of solar power this year, said Zhang Xiaoqiang, Vice Minister of the National Development and Reform Commission, at the Summer Davos forum held in Dalian, Liaoning Province, on September 11.

The nation's installed photovoltaic power capacity as of December 2012 was 6.5 million kilowatts (kw), according to the China Electricity Council. China will add at least 10 million kw of capacity every year from 2013 to 2015, according to the State Council.

The rapid growth will enable China to have a total installed solar capacity of 35 million kw by 2015.

Zhang also said that the country's wind power capacity has grown rapidly. Last year, wind power generation exceeded that produced by nuclear reactors, and it ranked 10th worldwide.
