Commerce Begins Review of Solar Panel Duties
Estimated reading time: 2–3 minutes
The U.S. Department of Commerce has initiated a review process to consider making changes to certain trade duties on solar panels imported from China. This review was requested by RNG International, Inc., a company that makes and exports these solar panels.
The solar panels in question are known as crystalline silicon photovoltaic (CSPV) panels. There are specific rules about which panels are covered by these duties. Certain small off-grid panels may now be excluded from the current duties.
On December 7, 2012, the Department of Commerce set up rules to impose duties on certain solar cells from China. More rules were added in February 2015. These duties help prevent dumping, which is when products are sold at unfairly low prices. They also counter subsidies, which some governments give to help their industries unfairly.
RNG International wants the Department to change these rules to exclude certain types of small, portable solar panels. These panels are usually used off-grid and are not fixed to buildings.
On April 23, 2026, RNG submitted a formal request to review the rules. They want panels that are under 200 watts and with a maximum size of 16,000 square cm to be excluded. These panels must not have an inverter built-in. Other specifics include how the panels are packaged and connected with wires.
Two groups in the U.S. that make solar panels, the American Alliance for Solar Manufacturing and T1 Energy Inc., agree with this proposed change. They filed letters saying they do not oppose this idea.
The Department of Commerce is asking for public input. This means people can share their thoughts on whether these specific solar panels should be excluded from the duties. The Department plans to make a preliminary decision soon, and they will allow more time for comments after their preliminary announcement.
This review shows that trade rules can change. It is important to watch these developments if you are interested in solar energy or international trade.
