Part 1: The Solar Panel Empire
How China Came to Make 80%+ of the World's Solar Panels
You install solar panels on your roof in California, Texas, or Florida. The installer tells you they're "American solar"—maybe even assembled in the US. You feel good about going green, reducing carbon emissions, energy independence. Here's what they probably didn't tell you: The polysilicon that makes those panels? Likely from Xinjiang, China. The silicon ingots and wafers? Processed in China. The solar cells? Manufactured in China. The aluminum frames? China. The junction boxes? China. Even if the final assembly happened in the US (slapping together Chinese-made components), 80-95% of the value was created in China. This isn't an accident. It's the result of a 20-year Chinese industrial strategy: subsidize manufacturers, build integrated supply chains, achieve scale that makes competition impossible, dominate the global market. And it worked spectacularly. In 2000, the US and Europe led solar manufacturing. By 2010, China had taken majority share. By 2020, China controlled 70%+ of every step in the supply chain. By 2026, China makes 80-85% of global solar panel production. The US share? Less than 5%. The result: Every country trying to decarbonize must either buy Chinese solar panels or spend years and billions building domestic manufacturing that still can't compete on cost. The "renewable transition" everyone talks about isn't just happening—it's happening on Chinese infrastructure, using Chinese equipment, making China the indispensable center of the global energy transformation. Welcome to the solar panel empire.
The Solar Supply Chain: Every Step Dominated by China
A solar panel isn't a simple product. It's the output of a complex, multi-stage supply chain. China doesn't just dominate one step—they dominate EVERY step.
The Supply Chain Stages:
1. Polysilicon Production (Raw Material)
- Purified silicon extracted from quartz
- Energy-intensive process (requires ~50-100 kWh per kg of polysilicon)
- Global production (2026): 1 million+ metric tons
- China's share: 85%+
- Xinjiang specifically: 45%+ of global supply
2. Ingot & Wafer Manufacturing (Silicon Processing)
- Polysilicon melted into ingots, sliced into thin wafers
- Precision manufacturing, economies of scale critical
- China's share: 95%+
3. Solar Cell Production (Conversion Layer)
- Wafers processed into photovoltaic cells (convert sunlight to electricity)
- Advanced technology (PERC, TOPCon, HJT cell types)
- China's share: 85%+
4. Module Assembly (Final Product)
- Cells assembled into panels with frames, glass, junction boxes
- Labor-intensive, less technically complex
- China's share: 80%+
POLYSILICON PRODUCTION:
China: 85% (850,000+ metric tons)
• Xinjiang region: 45% of global supply
• Rest of China: 40%
US: <5%
Germany: ~5%
Others: ~5%
INGOT & WAFER:
China: 95%+
Rest of world: <5% (mostly Taiwan, some US/EU)
SOLAR CELLS:
China: 85%+
Southeast Asia (mostly Chinese companies): 10%
US/EU: <5%
MODULE ASSEMBLY:
China: 80%+
Southeast Asia: 12%
US/EU: 5%
Others: 3%
TOTAL SOLAR PANEL PRODUCTION (2025):
Global: 600+ GW capacity
China: 500+ GW (83%)
US: 15-20 GW (3-4%)
EU: 10-15 GW (2-3%)
THE DOMINANCE:
China controls 80-95% of EVERY stage.
No other country comes close.
This is total supply chain control.
How China Captured Solar: The 20-Year Strategy
China didn't stumble into solar dominance. It was deliberate industrial policy executed over two decades.
Phase 1: Attract Technology (2000-2005)
In the early 2000s, solar technology was developed primarily in the US, Germany, and Japan. Chinese companies didn't invent solar—they imported the technology:
- Joint ventures: Western companies partnered with Chinese firms, transferring technology
- Talent acquisition: Chinese companies hired Western engineers, scientists
- Equipment purchases: Bought manufacturing equipment from Western suppliers
- Reverse engineering: Where necessary, copied designs
Western companies were happy to help—China was a huge potential market, and they wanted access.
Phase 2: Subsidize Scale (2005-2015)
Once Chinese companies had the technology, the government provided massive subsidies to achieve scale:
- Low-interest loans: State banks provided cheap capital (often below market rates)
- Land grants: Free or subsidized land for factories
- Energy subsidies: Cheap electricity for energy-intensive polysilicon production
- Export rebates: Tax incentives for exports
- R&D support: Government funding for technology improvements
Total subsidies (estimates): $40-50 billion+ over 10 years (exact figures opaque, mix of direct subsidies, cheap loans, implicit support)
The result: Chinese companies could sell solar panels below cost, driving Western competitors out of business.
Phase 3: Consolidate and Dominate (2015-2026)
By 2015, most Western solar manufacturers had exited or gone bankrupt. Chinese companies consolidated, achieved economies of scale, and now dominate:
- Top 10 solar manufacturers (2026): 8 are Chinese (Tongwei, Longi, JA Solar, Trina Solar, JinkoSolar, etc.)
- Cost advantage: Chinese panels cost 30-50% less than US/EU equivalents (if they existed)
- Technology leadership: China now leads in efficiency (TOPCon, HJT cells developed/scaled by Chinese firms)
- Vertical integration: Major companies own polysilicon → wafer → cell → module production (control entire chain)
The strategy worked: China went from zero to total dominance in 20 years.
The Xinjiang Problem: 45% of Solar Depends on Alleged Forced Labor
Here's where it gets complicated: 45%+ of global polysilicon comes from Xinjiang—the region where China is accused of detaining 1+ million Uyghurs and other minorities in "re-education camps."
Why Xinjiang?
Polysilicon production is energy-intensive (50-100 kWh per kg). Xinjiang has:
- Cheap coal power: Abundant coal, low electricity prices
- Government support: Xinjiang development is state priority (economic integration strategy)
- Proximity to raw materials: Quartz and metallurgical silicon nearby
Major polysilicon producers in Xinjiang:
- Hoshine Silicon Industry (largest globally)
- Daqo New Energy
- East Hope Group
- Xinte Energy
The Forced Labor Allegations
US government, human rights groups, and investigations allege:
- Uyghur workers forcibly transferred to factories
- Work assignments tied to "re-education" programs
- Restricted movement, surveillance, coercion
- Wages withheld or below market rate
China denies forced labor, claims programs are "vocational training" and "poverty alleviation."
The US Response: Uyghur Forced Labor Prevention Act (UFLPA)
Passed: December 2021, Effective: June 2022
The UFLPA creates a "rebuttable presumption" that goods from Xinjiang are made with forced labor and cannot be imported to the US unless companies prove otherwise.
Impact on solar:
- Solar panels or components from Xinjiang are presumed forced labor
- Importers must provide detailed supply chain documentation proving no Xinjiang content
- Customs and Border Protection (CBP) can detain shipments, demand evidence
- Many shipments detained (2022-2025: thousands of solar shipments held at border)
The problem: Most Chinese solar manufacturers source polysilicon from Xinjiang or companies that do. Supply chains are opaque. Proving "clean" sourcing is extremely difficult.
The Impossible Trade-off
Countries and companies face an impossible choice:
Option A: Buy Chinese solar (cheap, available, possibly forced labor)
- Fastest decarbonization (panels available immediately)
- Cheapest (Chinese panels 30-50% cheaper)
- Risk: Supporting forced labor, dependency on China
Option B: Avoid Xinjiang solar (expensive, limited supply)
- Ethical sourcing (no forced labor)
- Cost: Panels 30-50% more expensive OR not available at scale
- Result: Slower decarbonization, higher costs
Most countries choose A (buy Chinese solar, ignore or minimize forced labor concerns). Why? Because hitting climate targets requires deploying solar at massive scale, and only China can supply it.
The US is trying B (build domestic solar, avoid Xinjiang). But it's years away from having sufficient supply.
1. POLYSILICON (The Foundation)
• China: 85% of global production
• Xinjiang: 45% of global production
• Chokepoint: Can't make solar panels without polysilicon
• Vulnerability: Xinjiang forced labor allegations, US import restrictions
• Alternative: Build non-China polysilicon (US trying, expensive, slow)
2. INGOT/WAFER PROCESSING (The Bottleneck)
• China: 95% of global capacity
• Requires: Precision equipment, economies of scale
• Chokepoint: Even if you get non-China polysilicon, wafer processing still in China
• Alternative: Almost none (Taiwan has some, US negligible)
3. SOLAR CELL MANUFACTURING (The Technology)
• China: 85% of global production
• Technology leadership: TOPCon, HJT cells (China leads efficiency)
• Chokepoint: Most advanced cells made in China
• Alternative: Southeast Asia (often Chinese-owned), limited US/EU
4. EQUIPMENT SUPPLIERS (The Tooling)
• Manufacturing equipment mostly from: Europe (Meyer Burger), China
• Chokepoint: To build solar factories, you need equipment suppliers
• China increasingly making own equipment (reducing foreign dependency)
5. RAW MATERIAL INPUTS
• Quartz (for silicon): Widely available
• Silver (for electrical contacts): Limited supply, China refines 30%
• Aluminum (for frames): China produces 60% of global aluminum
CONCLUSION:
Every chokepoint controlled or dominated by China.
No diversified supply chain exists.
Building alternatives takes 5-10 years minimum.
The US Solar Industry Collapse: What Happened?
The US invented much of solar technology. In the 1990s-early 2000s, US companies were competitive. What happened?
The Rise and Fall of US Solar
The peak (early 2000s):
- SunPower: Leading high-efficiency solar panels (still exists but manufacturing mostly offshore)
- First Solar: Thin-film technology leader (survives, but small scale compared to Chinese giants)
- Evergreen Solar: Silicon wafer technology (bankrupt 2011)
- Solyndra: Cylindrical solar tubes (bankrupt 2011, huge political scandal)
- Abound Solar: Cadmium telluride panels (bankrupt 2012)
What killed them:
- Chinese competition: Subsidized Chinese panels flooded market, prices collapsed 80% (2008-2012)
- Inability to compete on cost: US labor, energy, capital all more expensive than China
- Lack of scale: Chinese factories 10x larger, achieving economies of scale US couldn't match
- Trade policy failure: US imposed tariffs (2012, 2018) but too little, too late
- Capital markets: Chinese companies got patient state capital, US companies needed quarterly profits
Solyndra: The Cautionary Tale
Solyndra became a political symbol of failed industrial policy:
- Funding: $535 million loan guarantee from US Department of Energy (2009, Obama administration)
- Technology: Cylindrical solar tubes (novel design, higher efficiency in some conditions)
- Problem: Chinese polysilicon prices crashed, making conventional flat panels so cheap Solyndra couldn't compete
- Outcome: Bankrupt 2011, $500M+ loss to taxpayers, massive political scandal
The lesson Republicans learned: "Government shouldn't pick winners" (industrial policy bad)
The lesson China learned: "Keep subsidizing until you dominate" (industrial policy works if you're patient)
The IRA Comeback: Can the US Rebuild Solar Manufacturing?
The Inflation Reduction Act (IRA, passed August 2022) is the US attempt to rebuild domestic clean energy manufacturing.
The Solar Provisions
Investment Tax Credit (ITC) + Production Tax Credit (PTC):
- 30% tax credit for solar installations
- Additional 10% bonus if using domestically-manufactured components
- Manufacturing credits: $0.07/watt for modules, $0.04 for cells, $12/sq meter for wafers, $3/kg for polysilicon
Total solar-related incentives: $30-40 billion over 10 years (estimates)
The Response (2022-2026)
Companies announced new US solar manufacturing:
- First Solar: Expanding Ohio, Alabama facilities ($1B+ investment)
- Hanwha Qcells: Georgia facility expansion ($2.5B)
- Enel (3Sun): Oklahoma factory ($1B)
- Numerous others: Total announced capacity 50-70 GW by 2026-2027
The Reality Check
Announced capacity (2026-2027): 50-70 GW/year
US solar demand (2025): 40-50 GW/year, projected 60-80 GW by 2027
Sounds good, right? Not so fast:
- Facilities not built yet: Most capacity won't come online until 2026-2028 (construction takes 2-4 years)
- Module assembly ≠ full supply chain: Most announced factories do final assembly using Chinese wafers, cells. They're assembling Chinese components, not making panels from scratch.
- Cost gap remains: Even with subsidies, US panels cost 10-30% more than Chinese (higher labor, energy, capital costs)
- Chinese capacity growing faster: China adding 100+ GW capacity annually. US adding 10-15 GW. The gap is WIDENING, not closing.
- Upstream supply missing: Very little US polysilicon, wafer, or cell production. Still dependent on China for components.
Conclusion: IRA will help, but it won't make the US self-sufficient in solar for at least 10+ years—if ever.
CHECK YOUR SOLAR PANELS (If you have them):
Look at the label on the back of your panels. It shows:
• Manufacturer name
• Model number
• Where it was made
Common manufacturers and their origins:
• Longi, JinkoSolar, JA Solar, Trina Solar = Chinese
• Hanwha Qcells = South Korean (but manufacturing in China + US)
• First Solar = US company (US manufacturing)
• Canadian Solar = Canadian company (manufacturing mostly in China)
Even "assembled in USA" often means Chinese wafers/cells.
RESEARCH TOOL:
EnergySage Solar Calculator (energysage.com)
Shows solar panel options, manufacturers, country of origin.
EXPERIMENT:
Search for "100% US-made solar panels."
You'll find very few options, all expensive.
That's the supply chain reality.
TOP SOLAR MANUFACTURERS (Revenue 2025):
CHINESE COMPANIES:
1. Tongwei Solar: $15B+ revenue
2. Longi Green Energy: $13B+
3. JA Solar: $9B+
4. Trina Solar: $8B+
5. JinkoSolar: $8B+
6. Canadian Solar: $7B+ (Canadian company, China manufacturing)
7. GCL: $6B+
8. Risen Energy: $5B+
Combined Chinese: $70B+ annual revenue
REST OF WORLD:
• First Solar (US): $3.5B
• Hanwha Qcells (S. Korea): $2.5B
• Meyer Burger (Switzerland): $500M
• Everyone else: Negligible
PROFITABILITY:
Chinese companies: Operating on thin margins (5-10%) due to overcapacity
But: Volume makes up for it + government support cushions losses
MARKET CAPITALIZATION (Public companies):
Longi: $30B+
First Solar: $20B
JinkoSolar: $5B
Trina: $6B
SUBSIDIES (Estimated total, 2005-2025):
China solar subsidies: $50B+ (opaque, includes loans, land, energy)
US IRA solar subsidies: $30-40B (2022-2032 projection)
China spent more over 20 years,
US trying to catch up in 10.
THE ECONOMICS:
Chinese companies dominate revenue, volume, capacity.
Western companies niche players or assemblers.
The money flows through China.
Historical Parallel: The Steel Industry Trajectory
PHASE 1 (1900-1970): US DOMINANCE
• US produced 40-50% of global steel
• Pittsburgh, Gary (Indiana), Great Lakes = steel centers
• Vertical integration: US Steel, Bethlehem Steel controlled mines → mills
• Technology leadership: Bessemer process, open hearth furnaces
PHASE 2 (1970-1990): JAPAN RISES
• Japan rebuilt post-WWII with modern mills
• Adopted new technology (basic oxygen furnace, continuous casting)
• Achieved economies of scale
• Undercut US prices, took market share
• US companies struggled, many went bankrupt
PHASE 3 (1990-2020): CHINA DOMINATES
• China subsidized steel capacity massively
• Built overcapacity (producing more than domestic demand)
• Exported at below-cost prices
• US/EU imposed tariffs, but China's scale was unstoppable
• By 2020: China produces 50%+ of global steel
THE PATTERN:
Technology leadership → moves to lower-cost manufacturer →
original innovator loses industry → new player dominates
SOLAR IS FOLLOWING THE EXACT PATTERN:
• US/Germany invented solar technology (1990s-2000s)
• China subsidized, scaled, undercut prices (2005-2015)
• US/EU companies bankrupted or marginalized (2010-2020)
• China now dominates (2020-present)
THE LESSON:
Once manufacturing moves to a lower-cost jurisdiction with
government support, it's nearly impossible to bring back.
The US lost steel. It lost solar. What's next?
(Spoiler: Batteries - see Part 2)
The Alternative Scenario: What If China Stops Exporting Solar?
TRIGGER:
Major US-China conflict (Taiwan, trade war escalation). China retaliates economically: restricts solar panel exports to "unfriendly nations" (US, allies).
MONTH 1: IMMEDIATE SHORTAGE:
• US solar installations drop 70-80% (no panels available)
• Prices spike 2-3x for remaining inventory
• Renewable energy projects stalled
• Utilities scrambling for alternatives
MONTH 3: CASCADE EFFECTS:
• Climate targets unreachable (solar is largest renewable deployment)
• Grid decarbonization plans delayed years
• Fossil fuel plants kept running longer
• Political backlash (voters want cheap energy + climate action, can't have both)
YEAR 1: SCRAMBLE TO REBUILD:
• IRA subsidies doubled, tripled (emergency measures)
• Factories fast-tracked (permitting expedited)
• But: Supply chain still in China (polysilicon, wafers, cells)
• Can build assembly plants, but can't make panels without Chinese components
YEAR 3: PARTIAL RECOVERY:
• Some US capacity online (30-40 GW, vs. 50-60 GW needed)
• Prices stabilized but 40-50% higher than pre-embargo
• Solar deployment permanently slower
• US fossil fuel consumption higher than planned
YEAR 5: NEW EQUILIBRIUM:
• US has domestic solar capacity, but smaller scale, higher cost
• Climate targets pushed back 5-10 years
• Economic cost: $hundreds of billions (slower transition, higher energy costs)
• Strategic lesson learned (too late): Supply chain dependency = vulnerability
THE LESSON:
China won't do this unless conflict forces it.
But they COULD. And the West has no good short-term alternative.
Solar dependency is strategic vulnerability.
Conclusion: The Green Transition Runs on Chinese Infrastructure
The solar panel empire reveals an uncomfortable truth: the renewable energy transition everyone celebrates is built almost entirely in China.
China makes 80-85% of solar panels through deliberate 20-year strategy:
- Subsidized manufacturers to achieve scale
- Built integrated supply chains (polysilicon → wafer → cell → module)
- Undercut Western competitors until they exited the market
- Now dominates every stage of production
The US and Europe face an impossible choice:
- Buy Chinese solar (cheap, available, ethical concerns, strategic dependency)
- Build domestic solar (expensive, slow, insufficient scale for climate targets)
Most countries choose Chinese solar because hitting decarbonization targets requires deploying panels at massive scale—and only China can supply that scale.
The IRA is trying to rebuild US solar manufacturing with $30-40 billion in subsidies. But:
- Factories take years to build
- Most will assemble Chinese components, not make panels from scratch
- China is adding capacity faster than the US can catch up
- Cost gap remains (US panels 10-30%+ more expensive)
The result: Energy transition dependency. Countries trying to decarbonize must buy equipment from China—creating new strategic vulnerabilities to replace old ones (Russian gas, Middle East oil).
This is the pattern we'll see repeated across energy infrastructure: China builds the equipment for the transition (solar, batteries, wind turbines, EVs, grid tech), while the West struggles to maintain competitiveness.
The solar panel empire is just the beginning.
