In May 2026, the Center for Strategic and International Studies (CSIS) released a major report: "China's Solar Industry Is in Upheaval — The Effects Will Be Global." The core judgment is sobering: China's solar photovoltaic sector is in a deep structural crisis whose impact will reverberate worldwide.
What Happened
China's solar PV industry experienced the world's most aggressive capacity expansion between 2020-2025:
- China now accounts for over 80% of global solar module production capacity
- Industry-wide profit margins hit historic lows in 2025, with second-tier firms operating at a loss
- Polysilicon prices have fallen over 80% from their 2022 peak
- Massive numbers of small and medium solar companies face bankruptcy or forced exit
Three Interlocking Tensions
1. Domestic overcapacity vs. slowing demand growth. Manufacturing efficiency has soared, but grid absorption capacity and energy storage infrastructure haven't kept pace. CREA notes China's 15th Five-Year Plan is shifting emphasis from "capacity expansion" to "system integration and efficiency."
2. Booming global demand vs. rising trade barriers. The US is pursuing anti-dumping investigations targeting Southeast Asia (where Chinese solar firms set up "transit bases"). India is building domestic PV capacity through PLI programs. The EU is developing a "solar autonomy" framework to reduce reliance on Chinese modules.
3. Low-price strategies vs. brand upgrade. Chinese module prices have fallen below $0.10/watt — making every non-Chinese manufacturer unprofitable. But the cost is compressed margins and minimal brand value.
Three Transmission Paths
CSIS identifies three channels through which the Chinese solar crisis will spread globally:
- Price shock — cheaper modules accelerate renewable deployment but crush non-Chinese manufacturers
- Investment uncertainty — overcapacity erodes investor confidence, tightening new project financing
- Trade friction escalation — governments face a dilemma between "cheaper solar" and "domestic manufacturing protection"
Lessons for Chinese Companies Going Global
Scale is not a moat. 80% global capacity means neither pricing power nor profit when the entire industry is driven by scale and cost-cutting.
Trade barriers aren't just "political." Europe and America's push for solar autonomy has real economic and employment logic.
The energy transition is not linear. Storage and smart grids — not more PV panels — are the next competitive battleground.
