Should the US loosen restrictions on cheap Chinese solar panels?

Even with the support of subsidies and tariffs, U.S. solar manufacturers struggled to compete with the flood of cheap solar panels pouring out of China into the global market. While some argue that the U.S. should loosen restrictions on cheap Chinese solar panels to accelerate renewable energy deployment, this approach is unsustainable.

How much does solar power cost in China?

Additionally, the cost of solar PV power generation was CNY5.6–15.1 kWh −1 in 2000, which fell to CNY0.29–0.79 kWh −1 in 2018, with an average annual decrease of CNY0.28–0.75 kWh −1 (Fig. 1). Technological progress sheds light on less expensive and more commercially viable solar systems, and increases the competitiveness of the solar PV market.

Does China offer a subsidy for onsite solar?

In addition, the Chinese government offers a subsidy for onsite solar generation of ¥.37/kWh (about $.06/kWh). In 2018, this subsidy decreased for the first time, and is expected to continue to decrease in the coming years.

Does China have a price threshold for solar power?

The cost of solar PV electricity generation is affected by many local factors, making it a challenge to understand whether China has reached the threshold at which a grid-connected solar PV system supplies electricity to the end user at the same price as grid-supplied power or the price of desulfurized coal electricity, or even lower.

Is onsite solar a good option for C&IS?

Onsite solar is the primary opportunity for corporates to focus on in China. A steep drop in costs has resulted in greatly improved returns, making PPAs for onsite generation an attractive option for C&Is. In addition, the Chinese government offers a subsidy for onsite solar generation of ¥.37/kWh (about $.06/kWh).

How much solar energy does Chongqing receive?

Chongqing is in the eastern part of the Sichuan Basin and receives on average 107 W m −2 solar radiation 24 with 732 kWh kW p−1 yearly solar energy conversion, from our calculations (Methods). Among all of the provinces, Chongqing has the lowest average solar availability capacity (<100 GW 25).
