China’s solar industry giants, long accustomed to leading global growth, have been hit by a severe market correction, reporting a combined net loss of nearly US$1.54 billion in the first half of 2025. An aggressive price war, fueled by a persistent oversupply of modules, has battered the profitability of the world’s largest manufacturers, despite record-breaking installation volumes.
Financial reports from the country’s four leading solar companies—Jinko Solar, LONGi Green Energy, Trina Solar, and JA Solar reveal the extent of the damage. While these firms collectively shipped over 147 gigawatts (GW) of modules, their profits were decimated. Jinko Solar reported a net loss of approximately RMB 2.91 billion (US406million),whileTrinaSolarfollowedcloselywithanetlossofRMB2.92billion(US408 million). LONGi and JA Solar also posted substantial losses of RMB 2.57 billion (US358million)andRMB2.58billion(US360 million), respectively.
This drastic swing into the red marks a significant turning point, with the combined losses from these four companies being more than two and a half times higher than in the same period last year. The primary culprit, analysts say, is a severe imbalance between manufacturing capacity and market demand. Even with a surge in China’s domestic installations, which nearly doubled to 212.2 GW in the first half of the year, the glut of available products has driven module prices to unsustainable lows.
In response, companies are attempting to navigate the challenging landscape by focusing on technological leadership and operational efficiency. Jinko Solar, which maintained its position as the global leader in module shipments, and others are heavily investing in next-generation technologies like n-type TOPCon to secure a competitive edge. Meanwhile, some firms are also diversifying into adjacent sectors, such as energy storage, to offset the shrinking margins from their core solar manufacturing business.
The financial results underscore a paradox facing the solar industry: rapid global growth and deployment are coexisting with a crisis of profitability for the very companies enabling that expansion. As the oversupply issue persists, the industry’s leaders will be forced to continue a brutal consolidation and innovation race to survive.
