Seven companies on Tuesday submitted a petition to the Biden administration, asking it impose duties on $12. 5 billion of solar equipment imported from Asia, per a Bloomberg report this morning.
A coalition of U.S. solar manufacturers submitted a request for investigation of alleged dumping of Chinese goods in four Southeastern Asian nations responsible for roughly 80% of U.S. solar panel supply. Shipping containers.
This action comes less than a year after the U.S. Department of Commerce made its final determination that Chinese solar manufacturers were circumventing tariffs on solar cells and solar panels by shipping their products through Cambodia, Malaysia, Thailand, and Vietnam.
The US has imposed new anti-dumping tariffs on solar panels imported from Southeast Asia, tightening restrictions on Chinese manufacturers accused of using these countries to avoid fair trade rules.
Companies including Qcells, First Solar, and Swift Solar on Wednesday asked the Biden administration to slap tariffs on solar cells from four countries in Southeast Asia. The US solar companies allege that Chinese-owned firms operating in Cambodia, Malaysia, Thailand, and Vietnam are illegally undercutting the market.
“We are seeking to enforce the rules, remedy the injury to our domestic solar industry, and signal that the U.S. will not be a dumping ground for foreign solar products.” This new petition comes eight months after Commerce did extend AD/CVD to Chinese solar manufacturers working in Southeast Asia.
The alleged dumping and subsidization of products made in Southeast Asia to avoid U.S. trade rules has led to a historic glut of solar panels believed to be sold at prices below the cost of production. The International Energy Agency (IEA) reports that there is a year and a half of stockpiled panels in American warehouses.

So far based on Solar PV Analysis of 119 locations in China, we've discovered that the ideal angle to tilt solar PV panels in China varies between 42° from the horizontal plane facing South in Jiam.
In China, solar photovoltaic (PV) installations in power plants and on rooftops are experiencing rapid growth and will continue for the next decades . Tilt angle is a critical parameter for installing PV panels. To maximize power generation, tilt angle should be adjusted to ensure that PV panels are exposed to direct sunlight.
The optimum tilt angle at the same location changes periodically (Fig. 7) due to the Earth revolution around sun. In summer, when the sun shines more directly on the northern hemisphere, the tilt angle is generally small; winter is the opposite. Adjusting the tilt angle of PV panels according to the season helps capturing more energy.
Furthermore, we explore the benefit from periodically adjusting the tilt angle in China. PV panels fixed at the optimum tilt angle increase the annual power yield by 13.7% compared with horizontally fixed panels.
Compared with the solar energy utilization potential of a PV placed on the horizontal surface, the annual average power generation of a PV panel placed at the optimum tilt angle can increase by up to 144.76 kWhm −2, with an average increase of 10.41%. 1. Introduction 1.1. Background
Jing et al. argued that the optimum tilt angle value in different regions of China ranges from 14.5° to 49.1°, and found that the theoretical optimum tilt angle value generally aligns with the law of angle increasing with latitude.
In our experiments, the optimum tilt angle can be as low as 0° in summer for locations near the Tropic of Cancer, but in practice, installers may tilt the panel at slightly larger angle to allow rainfall to naturally clean the panel .
