China controls more than 80% of global solar photovoltaic (PV) manufacturing across the supply chain as of late 2025.
Reputable sources, including the International Energy Agency (IEA), consistently report this figure for key stages:
Polysilicon Ingots Wafers Cells Modules
Data Points
The IEA states that China's share in all manufacturing stages of solar panels exceeds 80%, with upstream components (polysilicon, ingots, wafers) approaching or exceeding 95% based on current and under-construction capacity.
For solar modules specifically (the final assembled panels), China's production share was around 85% in 2023 and remains dominant into 2025, with global module manufacturing capacity projected to reach 1.8 TW by end-2025, largely driven by China.
Wood Mackenzie and other analysts projected China holding over 80% of polysilicon, wafer, cell, and module capacity through 2026, a trend that has held amid ongoing expansions.
In 2024–2025 reports (e.g., Fraunhofer ISE, Statista, PV-Tech), Asia (primarily China) accounts for 95–96% of global module production and components.
This dominance stems from massive investments (over USD 50 billion since 2011, per IEA), economies of scale, and policy support, enabling China to produce solar panels at lower costs than competitors. While countries like the US, India, and Europe are building domestic capacity (e.g., via incentives like the US Inflation Reduction Act), these efforts have not significantly reduced China's overall share by 2025.
Note that this refers to manufacturing capacity/production, not installed solar capacity (where China also leads but accounts for ~50–60% of annual additions). The ~80%+ figure is widely cited and substantiated across neutral industry sources.
