As for distributed solar power, there are two utilization models: (A) self-consumption and selling surplus to the grid; and (B) selling all solar generations to the grid. To reduce the costs of transmission and distribution (such as transmission loss), model A is more encouraged by the Chinese government.
An overview of the most recent development of solar energy in China. A new pattern from stationary to distributive forms of solar energy is highlighted. Reasons for the changing pattern: Diversified prices and subsidies. Challenges and policy options for the expansion of China's solar energy.
In addition, China is responsible for the processing of rare earth elements that are mined abroad. China worked hard to maintain its position as a leader in the production of assembled PVs and their parts. The country has also majorly invested in installed capacities. In the span of 25 years, China was able to install 393 GW of solar PV alone.
As shown in Section 2, one of the characteristic of the China's solar energy distribution is its concentration in remote areas such as northwest China and Inner Mongolia. As far away from load demand center, the power grid construction is relatively weak in those areas.
As China has the world's largest installed capacity of solar energy, the development of the solar power generation in China will have a profound impact on the healthy development of the global solar power industry. Based on the China's experience, the following suggestions are given for the other countries:
