Chinese PV Industry Brief: Polysilicon Prices Extend Decline

Why It Matters

Robust financing bolsters China’s PV expansion, while falling polysilicon prices pressure cost structures and could reshape supply‑chain dynamics across the global solar industry.

Key Takeaways

• CECEP raised ¥2.95 bn via convertible bonds for PV projects
• Six new PV plants and storage total 900 MW capacity
• Polysilicon prices fell seventh week, N‑type at ¥36k/MT
• Growing inventories outpace demand, pressuring solar module margins
• Longi and Huawei partner on storage and smart conversion tech

Pulse Analysis

China’s renewable energy push gained fresh capital this week as CECEP tapped the bond market for ¥2.95 billion ($432 million). The convertible issue, priced at ¥100 per bond, is earmarked for six solar farms and accompanying battery storage, delivering 900 MW of clean power. By bundling financing with a clear deployment plan, CECEP signals confidence in the domestic PV pipeline and offers a template for other state‑linked developers seeking lower‑cost capital amid tightening global funding conditions.

At the same time, the polysilicon market— a critical feedstock for solar cells—continued its downward trajectory for a seventh straight week. Average transaction prices slipped to ¥36,000 per metric ton for N‑type re‑feed material, roughly $5,000, while granular N‑type fell to ¥35,000. The China Nonferrous Metals Industry Association attributes the slide to inventory growth outpacing demand, a pattern that squeezes margins for module makers and could accelerate consolidation among lower‑cost producers. Companies reliant on silver‑based pastes, such as DKEM, already feel the strain, reporting sizable losses linked to commodity hedging and currency swings.

Strategic partnerships are emerging as firms adapt to the pricing pressure. Longi Green Energy and Huawei Digital Power announced a cooperation covering energy‑storage integration and intelligent string converters, aiming to boost system efficiency and offset raw‑material cost volatility. Meanwhile, CGN’s 1 GW Lao Northern Interconnection project, now grid‑connected, underscores the regional appetite for large‑scale solar assets. Together, these developments suggest a market in transition: abundant financing fuels capacity growth, but sustained polysilicon oversupply forces manufacturers to innovate and seek new value‑creation pathways.
