PVTIME – SEG Solar, a leading US-based PV module manufacturer, has announced the official launch of its first solar cell manufacturing plant in Indonesia. The 2GW Phase One project is now in full production. Located in the Batang Industrial Park, the facility will mass-produce the company’s own high-efficiency n-type solar cells, achieving an average conversion efficiency of 26.4%.
The plant’s initial phase comprises four production lines utilising innovative double-sided alternating printing equipment and screen-printing technology, enabling an average cycle time (CT) of 0.75 seconds per cell, 20% faster than traditional industry standards. A groundbreaking, industry-first sintering process further increases the absolute conversion efficiency by 0.3%.
Looking ahead, SEG plans to expand the plant’s capacity to 5GW annually and establish a fully vertically integrated manufacturing hub covering silicon ingots, wafers, cells, and modules. The facility will supply traceable, green-certified PV products to markets in the US, Europe and Indonesia. This milestone follows the commissioning of SEG’s 2GW Texas plant in August 2024, bringing its global module production capacity to over 6GW.
Against the backdrop of the US imposing high tariffs on traditional PV manufacturing hubs in Cambodia, Thailand, Malaysia and Vietnam, Indonesia and Laos are emerging as key manufacturing centres for US-bound solar products. According to the industry consultancy firm Sinovoltaics, the PV module capacity of Southeast Asia reached 78.8GW by late 2024 and is projected to exceed 92GW by 2027–2030. Over the same period, cell capacity is set to grow from 50GW to 68GW.
