Talesun’s last major module assembly expansion, which amounted to 5GW of capacity of advanced large-area wafer, half-cut module technology, came online in 2020 with an investment of around RMB2 billion (US$307 million). It features highly automated production lines and is located in Zibo City, Shandong province.

The company also took an impairment charge of around US$56.4 million in 2020 on outdated solar cell (1.7GW) and module assembly (2.4GW) production equipment in response to the rapid industry transition to larger-area wafers and new module string density packaging formats.

Furthermore, Talesun undertook a major retrofit of facilities based at its Changshu headquarters with advanced cell and module production equipment, featuring nameplate cell capacity of 1.5GW and module assembly capacity of 2.5GW.

A module assembly plant in Thailand with a nameplate capacity of around 1.5GW is also expected to be updated for larger-area wafer modules in 2021, after an upgrade of solar cell equipment in 2020.

The company did not disclose details concerning the capital expenditure required or the timelines for the new integrated cell and module project.

Talesun also has plans for a 1GW heterojunction (HJ) manufacturing plant and a 1GW N-type mono TOPcon facility.

PV Tech has been running PV ModuleTech Conferences since 2017. PV ModuleTech USA, on 16-17 June 2026, will be our fifth PV ModulelTech conference dedicated to the U.S. utility scale solar sector. The event will gather the key stakeholders from solar developers, solar asset owners and investors, PV manufacturing, policy-making and and all interested downstream channels and third-party entities. The goal is simple: to map out the PV module supply channels to the U.S. out to 2028 and beyond.
