One year of China, America’s entire fleet
In 2025 China commissioned nearly 370 GW of solar. The United States has 279 GW of solar standing from every year it has ever installed. A single Chinese vintage now outweighs a civilisation’s stock.

A flow that ate a stock
IEA Global Energy Review 2026: China commissioned nearly 370 GW of solar PV in 2025, on top of 357 GW in 2024. SEIA’s 2025 year-in-review: the United States ended the year with 279 GWdc of solar standing, after adding 43 GW (−14% on 2024). Put those on one axis and 2024 is the crossing — a single Chinese vintage larger than everything America has ever bolted down. Units are not identical (IEA commissioned GW vs SEIA GWdc). The gap is a hundred gigawatts. It does not care.
This is how a commodity is made
Pair with The cheapest electron and The century-long reign of coal is ending. China did not just install. It made the module, the wafer, the inverter, the price. Global additions cleared 600 GW; cumulative solar is about 2,800 GW, the largest generating fleet on Earth by capacity if not yet by electrons. The US still adds a Europe’s-worth of solar in a good year. It is no longer the plot. The plot is a factory system that can drop 370 GW on a calendar and still have a queue.
The long view is manufacturing as geopolitics
A 370 GW year is an industrial policy with a learning curve attached. Everyone else is a customer, a tariff, or a niche. The investing implication is not ‘short America’. It is: the module is a Chinese commodity, the interconnection is local, and the scarce rents sit in grids, storage, and the few non-Chinese steps that still have a process edge. Do not own a 2015 mental model in which the US fleet and China’s year are the same kind of number.

Horizon 5–15 years · Educational, not advice
China’s annual solar vintage is now larger than America’s installed base. Own the complements — grids, storage, interconnection — and the few manufacturing steps that are not a Chinese commodity. Do not own ‘more panels’ as a national-champion story.
Where the map points
- Transmission, transformers, interconnection-advantaged utilities
- Storage at $70–108/kWh next to constrained bays
- Non-Chinese niches with a real process edge, sized small
- Avoid a tariff-and-hope module assembler
What can break it
- AC vs DC and IEA vs SEIA are different yardsticks — the crossing is still not close
- US policy can slow additions without shrinking the Chinese year
- Overbuild that crushes even the complements for a cycle

The cheapest electron in history
Utility-scale solar now costs $44 per megawatt-hour. In 2010 it was about $445. That is a 90% collapse in fourteen years — the steepest learning curve of any energy technology we have a number for.

The century-long reign of coal is ending
In 2025, renewable electricity generated more power than coal for the first time in the modern era. Solar did most of the work.

2,500 gigawatts waiting for a wire
The IEA’s 2026 electricity report puts more than 2,500 GW of projects — renewables, batteries, data centres — in grid connection queues. The world spends $400 billion a year on grids and $1 trillion on generation. That is the distribution bottleneck.
