Discover the top 10 solar panel manufacturers by global shipments in 2025. Ranking with Jinko, LONGi, Trina, and JA Solar. . The world's top 10 solar photovoltaic (PV) module manufacturers shipped a record 500 gigawatts (GW) of modules in 2024, nearly doubling the previous year's volume, according to Wood Mackenzie's new Global Solar Module Manufacturer Rankings 2025 report. Despite this surge in shipments, the leading. . Solar panels (photovoltaic modules) are known as a symbol of solar power plants, but the general public may not be familiar with the top and leading panel manufacturers. Similarly, even among those working in the photovoltaic (PV) industry, I suspect that only a few people know about the annual. . In the latest consolidated data, global PV module production reached 726 GW and manufacturing capacity reached 1,405 GW/year, with 83% of capacity located in China. Capacity exceeded demand and module spot prices fell below $0. To give some perspective to the green power metrics, the value of exported fossil fuels including crude oil, processed petroleum oils, gases and coal was $3.
