SEG Solar: Phase I 2GW Project of Indonesia's Solar Cell Factory Commences Operation

US PV manufacturer SEG Solar has announced the official commissioning of the first phase of its 2GW solar cell production facility in Indonesia.

The factory will mass-produce SEG's independently developed high-efficiency n-type solar cells, with an average conversion efficiency of 26.4%. The first phase of construction includes four production lines utilizing screen printing technology, equipped with double-sided alternating printing equipment, achieving an average production cycle time of 0.75 seconds per solar cell. SEG stated that this speed is 20% faster than traditional industry standards.

Additionally, the factory has integrated a "disruptive, industry-first" sintering process independently developed by SEG, which can further enhance the absolute conversion efficiency by 0.3%.

In the future, SEG Solar plans to expand the factory's capacity to an annual production of 5GW and establish a vertically integrated PV manufacturing base covering ingots, wafers, solar cells, and modules. SEG stated that the factory will target the US, European, and Indonesian markets, committed to producing PV products with traceability and green certifications. Currently, SEG's annual production capacity for solar modules exceeds 6GW, including the 2GW factory in Texas, US, which commenced operations in August 2024.

It is worth noting that as the US imposes hefty tariffs on traditional production bases in Cambodia, Thailand, Malaysia, and Vietnam, Indonesia and Laos are gradually emerging as new PV manufacturing hubs for the US market. According to statistics from solar and ESS industry consultancy Sinovoltaics, as of the end of 2024, module production capacity in Southeast Asia has reached 78.8GW, and it is expected to exceed 92GW from 2027 to 2030. Solar cell production capacity is also projected to grow from the current 50GW to 68GW.
