Global supply chains for solar panels have begun shifting away from a heavy reliance on China, in part because of a recent ban on products from Xinjiang, a region where the U.S. government and United Nations accuse the Chinese government of committing human rights violations.
But a new report by experts in human rights and the solar industry found that the vast majority of solar panels made globally continue to have significant exposure to China and Xinjiang.
The report, released Tuesday, also faulted the solar industry for becoming less transparent about the origin of its products. That has made it more difficult for buyers to determine whether solar panels purchased to power homes and electricity grids were made without forced labor.
The analysis was done by Alan Crawford, a solar industry analyst, and Laura T. Murphy, a professor of human rights and contemporary slavery at Sheffield Hallam University in England, along with researchers who chose to remain anonymous for fear of retribution from the Chinese government. The London-based Modern Slavery and Human Rights Policy and Evidence Center provided funding.
The solar industry has come under stiff criticism in recent years for its ties to Xinjiang, which is a key provider of polysilicon, the material from which solar panels are made. The region produces roughly a third of both the world’s polysilicon and its metallurgical-grade silicon, the material from which polysilicon is made.
As a result, many firms have promised to scrutinize their supply chains, and several have set up factories in the United States or Southeast Asia to supply Western markets.
The Solar Energy Industries Association, the industry’s biggest trade association, has been calling on companies to shift their supply chains and cut ties with Xinjiang. More than 340 companies have signed a pledge to keep their supply chains free of forced labor.
But the report found that major global companies remain likely to have extensive exposure to Xinjiang, and potentially to forced labor, calling into question the progress. The report rated the world’s five biggest solar manufacturers — all with headquarters in China — as having “high” or “very high” potential exposure to Xinjiang.
Some Chinese companies, like LONGi Solar and JA Solar, have clear ties to suppliers operating in Xinjiang, the report said. But even within “clean” supply chains set up to serve the United States or Europe, many companies still appear to be getting raw materials from suppliers that have exposure to Xinjiang, Ms. Murphy said.
In many cases, according to the information they issue publicly, companies aren’t buying enough materials from outside Xinjiang to meet their production goals, indicating that they may be using undisclosed suppliers. In other cases, companies sent Ms. Murphy information about their supply chains that was directly contradictory.
“At every stage, there’s missing information,” she said.
