# Solar Panel Manufacturing Dominance

China produces over 80% of the world's solar panels and has driven module costs down 90% since 2010, making solar the cheapest electricity source in history
- Technology Readiness Level: 9/9
- Impact: 5/5
- Investment: 4/5
China controls every step of the solar supply chain: polysilicon refining, ingot pulling, wafer slicing, cell fabrication, and module assembly. LONGi, JA Solar, Trina, and JinkoSolar collectively produce more panels than the rest of the world combined.

The impact is reshaping global energy faster than any policy. Pakistan went from citizens burning electricity bills in protest to 20% solar power in two years — not because of climate policy, but because Chinese panels are so cheap that rooftop solar became the obvious economic choice. Solar imports into Pakistan grew fivefold from 2022 to 2024.

The dilemma: the world needs China's cheap solar to hit climate targets, but dependence on a single country for 80%+ of a critical energy technology creates supply chain risk. The EU and US are building domestic capacity, but at 3-5x the cost.
