PV manufacturer Zhongli Talesun has become the first of a wave of Chinese firms planning to establish manufacturing operations in Thailand to begin production in the Southeast Asian country.

The company said this week that it had begun the first phase of production at its new 500MW integrated solar cell and module assembly plant in the Thai-China Industrial Park in Rayong, Thailand, announced in February.

Zhongli Talesun had also previously said that the plant would produce PERC (passivated emitter and rear cell) technology for its new ‘Hipro’ 285W+ modules that were launched at SNEC in May. 

Talesun had said that the new PV modules would deploy solar cells with 20.3% conversion efficiencies, providing module conversion efficiencies of 17.55%.

The company noted in a financial filing in China that the start of production in Thailand would help the company further develop its PV business in Southeast Asia as well as across the world due to “effectively avoiding the impact of anti-dumping and anti-subsidies”, which included the US and EU. 

According to PV Tech’s tracking of new capacity expansion announcements, Thailand has attracted around 2.3GW of new production capacity since 2014, with 2.2GW of new capacity announced in the first nine months of 2015. 

Southeast Asia's burgeoning solar market will under the spotlight at the Solar & Off-Grid Renewables Southeast Asia event in Bangkok, Thailand, on 25 & 25 November. Organised by PV Tech's publisher, Solar Media, the event will offer unparalleled insights into emerging opportunities in the region from a top-level line up of speakers.

PV Tech has been running an annual PV CellTech Conference since 2016. PV CellTech USA, on 7-8 October 2025 is our third PV CellTech conference dedicated to the U.S. manufacturing sector. The events in 2023 and 2024 were a sell out success and 2025 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.
