Global Solar Manufacturing Statistics: Scale and Production Output
The 2024 production series measures output, while year-end capacity figures measure nameplate capability. They should not be treated as interchangeable: capacity can exceed actual production when factories operate below full utilization.
| Global measure | 2024 result | Change or scope |
|---|---|---|
| Polysilicon production | 1.96 million metric tons | Up 21.7% from 2023; includes semiconductor polysilicon |
| Wafer production | 804 GW | Up 18%; crystalline silicon |
| Solar-cell production | 753 GW | Up 17%; includes thin film |
| PV-module production | 726 GW | Up 19%; all module technologies |
| PV-module capacity | 1,405 GW/year | End-2024 nameplate capacity |
| Solar-cell capacity | 1,427 GW/year | End-2024 nameplate capacity |
Source: IEA PVPS Trends in Photovoltaic Applications 2025. The report’s capacity and production definitions differ, and the polysilicon total includes semiconductor material.
Global module output expanded from 116 GW in 2018 to 726 GW in 2024, an observed historical series rather than a forecast. Downstream deployment also grew: cumulative PV capacity surpassed 2,260 GW at the end of 2024, up 29% year on year, according to Trends in PV Applications 2025; installed capacity is downstream of manufacturing.
Raw Materials and Polysilicon Manufacturing Data
Metallurgical-grade silicon, or MG-Si, is an upstream input, while polysilicon is a more refined material used in the PV supply chain. The figures below distinguish annual capacity from annual production.
- Global MG-Si capacity reached 8.8 million metric tons per year in 2024, up 3.1% from 2023.
- China held 7.28 million metric tons per year of MG-Si capacity in 2024, about 83% of the global total.
- China produced 4.7 million metric tons of MG-Si in 2024, about 70% of world output.
- Two Tongwei Inner Mongolia MG-Si facilities had a combined capacity of 300,000 metric tons per year in 2024.
- China produced approximately 1.82 million metric tons of polysilicon in 2024.
The IEA PVPS Trends in Photovoltaic Applications 2025 reports a conditional projection that polysilicon capacity could rise from 3.25 million metric tons per year in 2024 to 5.00 million in 2025 if projects proceeded. This is a forecast, not an observed 2025 outcome.
Price data also show pressure in the upstream market. The polysilicon spot price fell from USD 7.28 per kilogram at the end of 2023 to USD 4.42 per kilogram at the end of 2024; spot price is not the same as manufacturing cost.
A historical concentration benchmark comes from the Solar Photovoltaics Supply Chain Review Report: China accounted for 95% of global polysilicon production capacity used in the PV supply chain in 2021. That DOE snapshot describes capacity, not annual output, and should not be read as a current figure.
Wafer and Solar-Cell Manufacturing Trends
Wafer and cell statistics capture different manufacturing stages. In 2024, China produced 776 GW of wafers, about 97% of global output, according to the IEA PVPS Trends in Photovoltaic Applications 2025.
Technology shifted quickly: the global n-type wafer share rose from 30% in 2023 to 70% in 2024. Format terminology also matters; an M10 wafer is 182 mm square, while an M6 wafer is 166 mm square.
The G10L specification used in one 2024 price series measured 182.2 by 183.75 mm and 130 micrometers thick. Its quoted price rose from USD 14.2 per piece in January 2024 to USD 19.0 at the end of April, then fell to USD 12.0 per piece at the end of May; these prices refer to the same specification and are not a general average for every wafer.
Capacity is also developing outside China. U.S. crystalline-silicon cell capacity was projected at 13 GW per year by the end of 2025, while India was reported at 15 GW per year in May 2025. The U.S. figure is a CEA projection and the India figure is capacity, not output.
PV Module Manufacturing Geography and Technology Mix
China dominated 2024 module production, but several other manufacturing locations reported material output.
| Location | 2024 module production | Measurement note |
|---|---|---|
| China | 627 GW | 1,156 GW/year capacity |
| India | 24 GW | Annual production |
| United States | 23 GW | Annual production |
| Vietnam | Around 20 GW | Annual production |
| Thailand | Approximately 10 GW | Annual production |
| Malaysia | About 7 GW | Annual production |
China supplied approximately 86% of global module output in 2024. The country totals and shares come from IEA PVPS Trends in Photovoltaic Applications 2025 and may reflect reporting coverage; capacity and output remain separate measures.
The technology mix was overwhelmingly crystalline silicon: it represented about 98% of global module production in 2024, while thin film represented about 2%, mostly CdTe. The production statistic includes all module technologies, whereas the technology split identifies their approximate shares.
Solar Manufacturing Costs, Prices and Utilization
Market prices and factory costs provide different signals. The global n-type module spot price for 580–625 W modules using 182 mm cells declined from USD 0.119/W at the start of 2024 to USD 0.078/W in December, according to IEA PVPS Trends in Photovoltaic Applications 2025.
For China manufacturing, the December 2024 production cost for a bifacial n-type module was RMB 0.692/W, about USD 0.0948/W. The source describes this as including tax and a minimum cost, so it is not directly equivalent to the global spot-price series.
Global factories also used a smaller share of their nameplate capability in 2024. Module manufacturing utilization was 52% in 2024, compared with 56% in 2023.
The DOE’s historical comparison found that U.S. silicon-module manufacturing cost was 30–40% higher than China’s in 2020. Labor represented 22% of U.S. silicon-module cost versus 8% in China, and imported components added about 11% to U.S. silicon-module cost; these are 2020 DOE/NREL comparisons, not current cost estimates.
U.S. industrial activity expanded after the Inflation Reduction Act period covered by the source. More than 35 newly operational U.S. solar factories announced after IRA represented over USD 3 billion and 9,500 jobs during 2022–2024 announcements, while DOE estimated U.S. PV-module capacity could reach about 40 GW by 2026.
The latter is a forecast; the factories span components.

Solar Supply-Chain Concentration and Downstream Equipment
Historical supply-chain data show why geography remains central to solar manufacturing discussions. In the DOE’s 2021 snapshot, China held 98% of global ingot capacity, 97% of wafer capacity, 81% of cell capacity and 77% of module capacity.
The same review reported that China-headquartered companies made 66% of global PV inverters in 2020, measured by company headquarters. Trade was also substantial: PV trade in polysilicon, wafers, cells and modules exceeded USD 40 billion in 2021, up more than 70% from 2020, while China’s solar-PV exports exceeded USD 30 billion in 2021.
Sources: Solar Photovoltaics Supply Chain Review Report and Executive summary – Solar PV Global Supply Chains – Analysis. The concentration figures are historical DOE data, and the trade total covers four product categories.
Downstream equipment expanded alongside modules. Global PV-tracker shipments reached 111 GW in 2024, up 20%, and global PV-inverter shipments reached 589 GW in 2024, according to IEA PVPS Trends in Photovoltaic Applications 2025.
The manufacturing outcome is also measured environmentally. IEA analysis estimates that panels needed four to eight months of operation to offset manufacturing emissions, compared with a 25–30 year lifetime, using current country electricity mixes.
The same analysis estimates that PV manufacturing absolute CO2 emissions nearly quadrupled from 2011 to 2021 while emissions intensity halved, and that PV manufacturing represented 0.15% of global energy-related CO2 emissions in 2021.
These are modeled estimates, not direct measurements of every factory. Looking ahead, the IEA net-zero roadmap says annual PV additions would need to exceed 630 GW by 2030; that is a roadmap requirement and therefore a forecast benchmark, not an observed production total.
