Solar panel manufacturing capacity statistics: global capacity by PV supply-chain stage
Solar manufacturing capacity is reported at several points in the photovoltaic (PV) supply chain. Figures in GW/year describe annual manufacturing rates; they do not state how much was produced. The reported global module capacity was 1,405 GW/year in 2024. Global cell capacity was 1,427 GW/year at the end of 2024, and wafer capacity was 1,395 GW/year in 2024. Their similar reported magnitudes give a view of downstream manufacturing scale, but the dates are not identical. (IEA PVPS, Trends in Photovoltaic Applications 2025, Figures 4.3 and pages 56–57)
Upstream silicon capacity is also measured in physical tonnage. Global polysilicon manufacturing capacity reached 3.25 million tons per year by the end of 2024 and included capacity serving both photovoltaic and semiconductor uses. In the PVPS supply-chain comparison, polysilicon capacity, including semiconductor capacity, is shown as 1,625 GW-equivalent for 2024. Metallurgical-grade silicon (MG-Si) production capacity was 8.8 million tons per year in 2024. These physical tonnage figures concern different materials and should not be treated as directly comparable. (IEA PVPS, Trends in Photovoltaic Applications 2025, page 54 and Figure 4.3)
| PV supply-chain stage or material | Reported capacity | Period and scope |
|---|---|---|
| Modules | 1,405 GW/year | Global, 2024 |
| Solar cells | 1,427 GW/year | Global, end of 2024 |
| Wafers | 1,395 GW/year | Global, 2024 |
| Polysilicon | 3.25 million tons/year | Global physical capacity; PV and semiconductor uses, end of 2024 |
| Polysilicon, chart convention | 1,625 GW-equivalent | Global; includes semiconductor capacity, 2024 |
| Metallurgical-grade silicon | 8.8 million tons/year | Global physical production capacity, 2024 |
The IEA’s Renewables 2025 gives a separate estimate of 1,100–1,350 GW for global module manufacturing capacity in 2024. The IEA PVPS figure and this range are different reported estimates and scopes. They should remain distinct rather than being averaged or treated as interchangeable measurements. (IEA, Renewables 2025, page 83; IEA PVPS, Trends in Photovoltaic Applications 2025, page 54)
Solar panel manufacturing capacity statistics: cell, wafer and module capacity by region
China held approximately 1,302 GW/year of solar cell capacity at the end of 2024. Its wafer manufacturing capacity was 1,349 GW/year in 2024, while its PV module manufacturing capacity was 1,156 GW/year that year. Each figure describes a distinct manufacturing stage. (IEA PVPS, Trends in Photovoltaic Applications 2025, pages 56–58)
The reported module capacities for the United States and India were 42.1 GW/year and 61 GW/year, respectively, by the end of 2024. Both are production-capacity figures, not module production totals. (IEA PVPS, Trends in Photovoltaic Applications 2025, page 58)
| Region | Stage | Capacity | Reference date |
|---|---|---|---|
| China | Solar cells | Approximately 1,302 GW/year | End of 2024 |
| China | Wafers | 1,349 GW/year | 2024 |
| China | PV modules | 1,156 GW/year | 2024 |
| United States | PV modules | 42.1 GW/year | End of 2024 |
| India | PV modules | 61 GW/year | End of 2024 |
These figures illustrate why country comparisons need to keep the manufacturing stage in view. Module capacity alone does not describe a country’s cell or wafer capacity, and the reported observations do not constitute a complete country-by-country inventory across all stages. (IEA PVPS, Trends in Photovoltaic Applications 2025, pages 56–58)
Solar panel manufacturing capacity statistics: regional manufacturing capacity outside China
For 2024, the IEA reported ASEAN manufacturing capacity alongside each stage’s share of global capacity excluding China. ASEAN had 100 GW of module capacity, equal to 40% of capacity outside China. Cell capacity was also 100 GW, equal to 70% of the non-China total. At the wafer stage, 50 GW represented 90% of global capacity excluding China. ASEAN polysilicon capacity was 15 GW, or 20% of the corresponding non-China total. (IEA, Renewables 2025, page 86)
| ASEAN PV manufacturing stage | Capacity in 2024 | Share of global capacity excluding China |
|---|---|---|
| Modules | 100 GW | 40% |
| Cells | 100 GW | 70% |
| Wafers | 50 GW | 90% |
| Polysilicon | 15 GW | 20% |
The denominator matters: these percentages compare ASEAN with global capacity excluding China, not with total world capacity. The wafer figure, for example, describes ASEAN’s share among producers outside China. (IEA, Renewables 2025, page 86)
U.S. capacity changed at two reported endpoints between 2022 and 2024. Module manufacturing capacity went from 9 GW in 2022 to 45 GW in 2024. Polysilicon production capacity, expressed in GW-equivalent, went from 21 GW to 33 GW over the same endpoints. The IEA says IRA support contributed to these increases; these two observations do not provide a year-by-year series. (IEA, Renewables 2025, page 85)
Solar panel manufacturing capacity statistics: capacity growth and historical benchmarks
The IEA estimates that global PV manufacturing capacity expanded in 2024 by approximately 70 GW for cells and approximately 190 GW for modules and wafers combined. The latter is a combined figure, with no separate addition given for modules and wafers. Polysilicon capacity expanded by a record 460 GW under the source’s GW convention. These are capacity changes, not production volumes. (IEA, Renewables 2025, page 83)
For non-China module manufacturing capacity, the IEA reports that capacity exceeded installations by approximately 20% in 2024. This comparison places manufacturing capacity against installations; it is not a measure of production or utilisation. (IEA, Renewables 2025, page 87)
The U.S. endpoint figures offer a historical reference across two stages: modules rose from 9 GW in 2022 to 45 GW in 2024, while polysilicon production capacity, expressed in GW-equivalent, rose from 21 GW to 33 GW. Because the figures concern different stages and conventions, they describe separate trajectories rather than a direct comparison of equivalent manufacturing capacity. (IEA, Renewables 2025, page 85)
Solar panel manufacturing capacity statistics: capacity versus production and utilisation
Capacity represents an annual manufacturing rate; production is the amount made over a period. In 2024, global solar cell production, including thin-film technologies, reached 753 GW. Global PV module production, including crystalline silicon and thin-film technologies, reached 726 GW. The PVPS supply-chain chart reports global module capacity of 1,405 GW/year and module production of 726 GW for 2024. For polysilicon, the chart gives 1,625 GW-equivalent of capacity, including semiconductor capacity, and 950 GW-equivalent of production. (IEA PVPS, Trends in Photovoltaic Applications 2025, pages 54 and 57 and Figure 4.3)
Global wafer production reached 804 GW in 2024, while reported wafer manufacturing capacity was 1,395 GW/year. The source also reports that wafer production rose 18% from the previous year; this is a production growth rate, not a capacity increase. (IEA PVPS, Trends in Photovoltaic Applications 2025, page 56 and Figure 4.6)
The IEA defines PV manufacturing utilisation as production relative to nameplate capacity. It estimates average global utilisation at 55–65% in 2024, down from 60–80% in 2023. The outlook says utilisation could fall below 50% in the short term before gradually rebounding to 50–60% by 2030; these are forecasts, not observed results. (IEA, Renewables 2025, page 84)
The reported global ranges describe the relationship between output and nameplate capacity at the PV manufacturing level. They are not separate utilisation rates for each country or stage. Capacity alone does not establish output, and a production total alone does not identify how much manufacturing capacity was available in that period. (IEA, Renewables 2025, page 84)
Solar panel manufacturing capacity statistics: announced additions and forecast limits
For 2025–2030, the IEA forecasts 230 GW of new global PV module manufacturing capacity, 190 GW of new cell capacity and 80 GW of new wafer capacity. Around 35% of new global PV manufacturing additions over that period were expected outside China, compared with less than 10% over the preceding six-year period. These figures describe forecast additions and shares, not confirmed project completions. (IEA, Renewables 2025, page 83)
China was projected to retain a 75–95% share of global PV manufacturing capacity in 2030. The outlook also projected that non-Chinese module capacity would exceed local deployment by over 30% by 2030. The first figure is a projected global capacity share; the second compares capacity with local deployment. Neither is a measured outcome for 2030. (IEA, Renewables 2025, pages 83 and 87)
The reports cite country projections with distinct technologies and dates. IEA PVPS reports a projection for U.S. crystalline-silicon cell manufacturing capacity to reach 13 GW/year by the end of 2025. For India, it reports an NSEFI projection for crystalline-silicon wafer capacity to rise from 6 GW/year in 2025 to 100 GW/year by 2030. Indian cell production capacity was reported at 15 GW/year by May 2025, with NSEFI forecasting 120 GW/year by 2030. The projected values are attributed forecasts, not verified future capacity. (IEA PVPS, Trends in Photovoltaic Applications 2025, pages 56–57)
The IEA’s 2025 outlook also describes expected closures in ASEAN. It reports that planned U.S. tariffs led to halted investment activity and expected closure of approximately 40 GW of module capacity and 25 GW of cell capacity in Viet Nam, Thailand, Malaysia and Cambodia. This is an outlook statement about expected closures, not confirmation that the closures were completed. (IEA, Renewables 2025, page 86)
