6月底以来,光伏市场风云突变,产业链各环节价格异动,多晶硅主力期货合约在一个月内飙升80%,7月24日每吨到5.38万元。
Since the end of June, the photovoltaic (PV) market has experienced dramatic changes, with volatile pricing across various segments of the supply chain. The main polysilicon futures contract soared by 80% within a month, reaching 53,800 yuan (approximately $7,410) per ton as of July 24.
近年来股价跌跌不休的光伏龙头股也集体苏醒了。通威股份(600438.SH)、协鑫科技(03800.HK)、大全能源(688303.SH)、新特能源(01799.HK)股价一月内拉涨超过五成;隆基绿能(601012.SH)、晶科能源(688223.SH)、晶澳科技(002459.SZ)、阿特斯(688472.SH)等同期也“回血”了15%—30%。
In recent years, leading photovoltaic stocks—whose share prices had been on a continuous downward slide—have collectively rebounded. Shares of Tongwei Co. (600438.SH), GCL Technology Holdings (03800.HK), Daqo New Energy (688303.SH), and Xinte Energy (01799.HK) surged by more than 50% within one month. During the same period, companies such as LONGi Green Energy (601012.SH), JinkoSolar (688223.SH), JA Solar Technology (002459.SZ), and Canadian Solar (688472.SH) also recovered by 15% to 30%.
激活光伏市场的动力来自“反内卷、去产能”的强力政策预期。多名行业人士对财新称,6月底国家发改委派员前往光伏产业链一线调研各环节成本、价格,深入了解了业界低开工率、“卷”低价竞标、踩踏式恶性竞争等现状,光伏企业虽然想自发限价、控产量、清库存等,但靠企业间协同自律十分困难。
The driving force behind the photovoltaic market’s recent activation stems from robust policy expectations aimed at “countering excessive competition and reducing overcapacity.” Several industry insiders told Caixin that, at the end of June, the National Development and Reform Commission dispatched officials to the frontlines of the photovoltaic industry chain to investigate costs and prices across various segments. The delegation gained an in-depth understanding of current challenges, including low operating rates, cutthroat price competition, and destructive market rushes. Although photovoltaic companies are eager to introduce self-imposed price limits, control production, and clear out inventories, they find it extremely difficult to achieve these goals through voluntary coordination within the industry.

- DIGEST HUB
- Since late June 2025, China’s polysilicon futures surged 80% in a month amid policy-driven expectations to curb “involution” (malignant price wars) and reduce overcapacity; major photovoltaic (PV) stocks rose over 50%.
- China’s PV production capacity now exceeds global demand by nearly twofold; 2024 saw sector-wide losses, with polysilicon, wafer, and module prices falling 29–50% below cost.
- Proposed industry-wide restructuring aims to consolidate excess capacity through joint platforms and debt restructuring, but complex negotiations and persistent oversupply challenge recovery.
Since late June, China’s photovoltaic (PV) market has experienced dramatic turbulence, with prices surging across the supply chain. Leading the spike was polysilicon, whose main futures contract climbed 80% in one month to reach 53,800 yuan/ton on July 24, 2024[para. 1]. Stock prices of major PV companies such as Tongwei, GCL Technology, Daqo New Energy, and Xinte Energy rose by over 50% in the same period, while others like LONGi Green Energy and Jinko Solar regained 15–30%[para. 2].
This market activation was driven by strong policy expectations focused on curbing “involution” (excess competition) and excess capacity. The National Development and Reform Commission (NDRC) and Ministry of Industry and Information Technology (MIIT) initiated investigations and meetings from late June through July 2024 to address low utilization rates, cutthroat pricing, and unhealthy competition. The government signaled intention to manage price competition and eliminate backward capacity[para. 3][para. 4], extending these expectations to overcapacity sectors beyond PV[para. 5].
Polysilicon futures, launched in December 2024, have attracted speculative and institutional capital, but most funds are short-term oriented. For example, on July 23, polysilicon futures volume rose 67% while open interest fell by 15%—indicating fast turnover rather than sustained investment[para. 6]. Analysts argue the solution lies in legal price floors and industry self-regulation, with a focus on upstream supply control to balance supply and demand across the PV value chain[para. 7][para. 8].
Industry leaders plan to create a platform company for consolidated production and coordinated supply management, focusing on joint acquisition of excess capacity. This is feasible as the top 7 polysilicon producers control over 80% of total capacity in China, making upstream coordination more likely than downstream integration[para. 9][para. 10].
China’s PV industry underwent exponential expansion from 2020, with polysilicon capacity rising nearly sevenfold to 3.2 million tons by end-2024, while wafer, cell, and module capacity increased over fourfold. Current capacity at all levels nearly doubles (or exceeds) global demand projections, leading to deep losses: polysilicon, wafer, cell, and module prices in 2024 fell by 29–50%, with most prices below cash cost[para. 11][para. 12].
Despite policy efforts, challenges persist. Upstream companies have raised spot offers based on higher costs, but low transaction volume and speculative restarts undermine efforts to scale back supply. Downstream module prices remain stuck due to weak terminal demand and uncertainty around government energy policy and project returns[para. 13][para. 14].
Losses have triggered partial production cuts and discussions on sector consolidation, but with little material progress due to divergent interests, local government involvement, and the resilience of companies—many propped up by local governments, subsidies, and financial leverage[para. 15][para. 16][para. 17]. Notably, in 2024, top firms like Tongwei, GCL, Xinte, and Daqo suffered heavy net losses, and across the supply chain, job cuts and bankruptcies have been widespread[para. 18][para. 19].
Efforts are underway to set up a multi-stakeholder platform for capacity acquisition and restructuring, supported by banks and asset managers. The approach envisions using future profits from market stabilization to repay existing debts, buying time to digest excess capacity[para. 20][para. 21][para. 22]. However, obstacles include consensus on valuation, distribution of benefits, exit mechanisms, and legal concerns over potential anti-monopoly violations[para. 23][para. 24].
As domestic and global demand growth slows, compounded by changing overseas energy policies, the market faces continued downward pressure despite short-term speculative rallies. The root issue remains severe oversupply, and the path to industry rationalization will be slow, painful, and heavily dependent on effective policy enforcement and collective action[para. 25][para. 26][para. 27].
