China-based PV module manufacturer Sunport Power has officially started production at 1GW assembly plant using Eurotron’s MWT equipment for back-contact PV modules that reduce cell-to-module losses and boost module performance.

Sunport Power CEO, Dr Zhang said, “Back-contact modules come with substantial benefits. The most important being production capacity per panel in comparison to traditional methods. Thanks to our Eurotron production line that was already in operation, my clients already experience these advantages first-hand. Back-contact solar panels avoid capacity losses associated with shade and resistance in traditional panels. This means our clients generate more energy per square metre.”

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.
