In March this year, the US Department of Commerce announced that it would launch an anti circumvention investigation on solar products imported from four Southeast Asian countries, namely Malaysia, Thailand, Vietnam and Cambodia. The time progress announced at that time was that on March 28, the US Department of Commerce launched an anti circumvention investigation on products imported from the four Southeast Asian countries, announced the investigation results on August 30, and made a final decision on January 26, 2023.

Affected by this, more than half of the Chinese manufacturers' shipments to the United States have been delayed or cancelled, resulting in a sharp decline in the supply of American components. This time, the Biden government announced the change of policy relaxation for the four countries in Southeast Asia. First, it is good for the recovery of the local photovoltaic installation in the United States, especially the current time limit is two years. Within two years, the U.S. photovoltaic installation is expected to usher in rush, and it is also good for the recovery of Chinese photovoltaic enterprises' production capacity in Southeast Asia and their exports to the United States.

At present, China's major photovoltaic enterprises, such as Longji Green Energy, Jingao Technology, Trina Solar, Jinko Energy, CSI, Dongfang Risheng, are leading in capacity distribution in Southeast Asia. According to incomplete statistics of public data (including the expected new capacity), Longji has silicon chip/battery/module capacity of about 4.1/8.5/8.6 GW in Southeast Asia; About 4/5/3.5GW in Jingao; Trina Solar has a total battery/component capacity of about 6/6GW.

Seen wisdom research believes that the shift of US policy can reflect the high dependence of US PV on supply chains outside the US. At present, more than 70% of American photovoltaic products still need to be imported, and the self-sufficiency rate is low, which makes it difficult to achieve its installation target of 22.5GW in 2024. In the context of the realization of the global dual carbon goals, it is unrealistic for the United States to achieve the dual carbon goals through self-sufficiency. In recent years, Chinese integrated component enterprises have built a large amount of capacity in Southeast Asia, so this news is good for domestic enterprises with integrated capacity in Southeast Asia, including the export of inverters, components, supports and other branches. These enterprises are expected to obtain excess profits in the U.S. market.
