Solar energy 5kWh power real power in China at night

How much solar power does China have?

In 2014, China's PV cumulative installed capacity reached 28.05 GW. Currently, supportive policies in China focus on the national level. Few of these policies consider regional difference, such as the distribution of solar radiation and economic development.

Why is solar energy underestimated in China?

The missing radiation data over the western domain may lead to the underestimation of the total solar energy in China. Second, the application of 11 PV models reveals an uncertainty of 6–7 % in the estimate of PV power potential.

How does solar radiation affect PV power potential in China?

With the increase of 1 W m −2 in solar radiation, the PV power potential in China shows a uniform enhancement of 1.22–1.41 kWh m −2 (Fig. 8 d). On the national scale, the PV power potential increases by 1.34 kWh m −2 (0.55 %) per unit 1 W m −2 solar radiation with almost linear responses to the changes in radiation (Fig. 8 a and Fig. S16).

Does China have a large-scale consumption of PV power generation?

However, our conclusions have policy implications for the large-scale consumption of PV power generation in China and other countries. In 2014, China's PV cumulative installed capacity reached 28.05 GW. Currently, supportive policies in China focus on the national level.

How much solar radiation does China have?

According to the Wind and Solar Energy Resources Center, China Meteorological Administration, the amount of solar radiation is more than 1400 kWh/m 2 in most parts of China, which is more than other countries with a similar latitude. But the radiation is not evenly distributed across China.

What is the PV power potential in China?

We estimated the PV power potential in China using an ensemble of 11 PV models driven by high-resolution satellite data. We predicted a national average PV power potential of 242.79 kWh m −2 in China for 2016–2019, with the east-to-west gradient from 219.81 kWh m −2 to 273.51 kWh m −2.
