‘Solar Module Super League’ (SMSL) member, GCL System Integration Technology (GCL-SI) is to build a 60GW solar module megacomplex in Hefei City, China at a cost of approximately US$2.5 billion over a four-year period. 

The solar module megacomplex is the largest such project ever announced in the solar industry, according to PV Tech’s analysis.

GCL-SI signed an investment cooperation agreement with the People's Government of Feidong County in Hefei City, Anhui Province, China with the megacomplex to be located in the Feidong County Circular Economy Demonstration Park, occupying the equivalent of 1.33km² to house all manufacturing operations and partner manufacturing and supply chain operations that would be necessary for such a large new manufacturing hub.

The megacomplex will include wafer, cell, module and all component manufacturing such as junction box, backsheets, glass, EVA and aluminium frames and work is to start in 2020.

The four-year, four-phase implementation plan includes an annual investment of approximately RMB 5 billion (US$700 million) for 15GW of integrated PV module assembly capacity. The facilities would also be highly automated and include an array of advanced manufacturing technologies.

GCL-SI also noted that the majority of module manufacturing would be focused on using 210mm x 210mm large-area monocrystalline wafers. 

A key aim of the megacomplex is to meet future demand and significantly drive down the manufacturing cost of PV modules to unprecedented levels.

PV Tech has been running an annual PV CellTech Conference since 2016. PV CellTech USA, on 13-14 October 2026 is our third PV CellTech conference dedicated to the U.S. manufacturing sector. The events in 2023, 2024 and 2025 were a sell out success and 2026 will once again gather the key stakeholders from PV manufacturing, equipment/materials, policy-making and strategy, capital equipment investment and all interested downstream channels and third-party entities. The goal is simple: to map out PV manufacturing in the U.S. out to 2030 and beyond.
