The National Energy Administration issued a notice on the Publication of the Results of the National Subsidy Bidding for 2019 PV Power Generation Projects in July, announcing that based on the principle of fairness, 3,921 projects with total installed capacity of 22.79 GW in 22 provinces, autonomous regions and municipalities such as Beijing and Tianjin have been included in the 2019 national bidding subsidy, initiating the first step of the marketization of China's PV industry.

Li believes that the entire PV industry in China will usher in fully market-oriented opportunities, after achieving the grid parity, without any need for government subsidies. Fewer subsidies in the overseas markets correspond to the market-oriented practice.

"Therefore, as the cost of establishing PV stations becomes much lower, there is no need for subsidies in China, and the world will also enter the growth phase of demand explosion," he stressed.

Agreed Sun Fuquan, a researcher at the Chinese Academy of Science and Technology for Development in Beijing. He said China's ability in cost control, in terms of unit production cost, will continue to provide companies with an advantage if they bid for projects in overseas markets.

He said the terminal electricity prices in many countries remain relatively high, and the development of renewable energy sources such as PV and wind power offer competitive alternatives.

Apart from the energy cost, it is critical to take steps to deal with climate change. China is willing to continue cooperating with global partners to advance emission cuts, climate adaptation and sustainable development. The country will also push for global free trade and a rule-based multilateral trading system, Sun said.
