Polysilicon Prices Plunge, with Maximum Decline Exceeding 12%

Why It Matters

The slump signals a tightening profit margin for solar‑grade silicon suppliers and could delay cost reductions for photovoltaic projects, affecting the broader renewable‑energy rollout. Investors and policymakers must monitor inventory levels to gauge the need for stimulus or capacity adjustments.

Key Takeaways

• Polysilicon prices fell up to 12.9% month‑on‑month.
• Inventory reached 480,000 tons, highest recent level.
• Production dropped 17.3% in February, slight March rise expected.
• Weak downstream demand hampers price recovery.
• Wafer prices slipped 3.5‑8.3% earlier this month.

Pulse Analysis

The Chinese polysilicon market is entering a correction phase as excess inventory collides with tepid demand from solar‑cell and module manufacturers. Data from the Silicon Industry Branch shows that nine leading producers—accounting for nearly 90% of national output—have collectively lowered prices, with n‑type granular grades dropping almost 13% month‑on‑month. Such a rapid price adjustment reflects a supply glut, highlighted by a record 480,000‑ton stockpile, and underscores the fragility of demand recovery after the post‑holiday slowdown.

Downstream effects are already visible. Module assemblers, which rely on stable silicon pricing to forecast project economics, now face higher input cost volatility. The concurrent dip in wafer prices, ranging from 3.45% to 8.33%, suggests that manufacturers are passing on some of the price pressure, potentially compressing margins across the value chain. Without a clear stimulus package or a surge in new solar installations, the sector may experience a prolonged destocking period, prompting producers to consider output cuts or shift toward higher‑value specialty grades.

Looking ahead, analysts anticipate a modest rebound in production volumes for March, but the increase is unlikely to offset the entrenched inventory surplus. Market participants are watching policy signals closely; any supportive measures—such as feed‑in tariffs or green financing incentives—could reignite demand and stabilize prices. In the meantime, investors should weigh the risk of further price erosion against opportunities to acquire capacity at discounted rates, as the polysilicon landscape reshapes in response to global renewable‑energy dynamics.
