Yingfa Ruineng, through its subsidiary Yingfa BCI (BCI), has introduced its Indonesian solar cell manufacturing facility with an annual production capacity of 7.5 GW of N-type TOPCon solar cells. The technology launch event was held in Jakarta, where the company presented its manufacturing capabilities, technology developments, and plans to strengthen Indonesia’s domestic solar supply chain. The facility marks Yingfa Ruineng’s first overseas manufacturing base and is expected to serve as a regional supply hub for Southeast Asia, the Middle East and other international markets.
Around 80 representatives attended the event, including officials and representatives from Indonesian government-related institutions such as BKPM, EBTKE and IPAMP, along with industry associations AESI and APAMSI. Customers from Indonesia and neighbouring markets also participated. Zhang Min, President of Yingfa Ruineng, and Xu Zhenyu, General Manager of BCI, were among the key company representatives present.
The company stated that its Indonesian manufacturing investment supports the country’s 100 GW solar power programme and its efforts to expand domestic manufacturing capabilities. The facility is also expected to contribute to Indonesia’s local content requirements, known as Tingkat Komponen Dalam Negeri (TKDN), subject to applicable certification and regulatory conditions. Local solar cell production could help Indonesian module manufacturers improve supply availability, reduce transportation timelines, and coordinate more closely with technology suppliers.
Yingfa Ruineng currently operates four major manufacturing bases in Tianchang, Yibin, Mianyang and Indonesia. Together, these facilities have an effective manufacturing capacity of 51.5 GW, including 45.5 GW of N-type TOPCon capacity. The company reported that overseas markets contributed 40% of its total revenue in 2025, with its products supplied to more than 20 countries and regions.
At the Jakarta event, Yingfa Ruineng also presented its technology roadmap, covering half-cell passivation, multi-cut cell designs and back-contact (BC) solar cell technology. These technologies are intended to improve manufacturing efficiency and support the development of high-performance photovoltaic products. Its BC technology positions electrical contacts on the rear side of the cell, leaving the front surface free of front-side electrical contacts. This design can support high-efficiency solar applications, including rooftop systems, off-grid installations, and microgrids.
The company reported a TOPCon cell efficiency of 27.3% and a BC cell efficiency of 28%, based on specific cell designs and testing conditions. It has also completed an initial end-to-end fabrication process for perovskite/BC tandem solar modules as part of its research and development activities.
Beyond manufacturing, Yingfa Ruineng plans to strengthen its presence in Indonesia through workforce development, local supplier partnerships and technical service capabilities. The company aims to work with domestic manufacturers, project developers, EPC contractors and government institutions to expand cooperation across the photovoltaic value chain.
Through its Indonesian subsidiary, Yingfa Ruineng aims to combine local production with international manufacturing experience and technology development. The 7.5 GW facility is expected to strengthen regional solar cell supply capabilities while supporting Indonesia’s ambitions to develop its domestic photovoltaic manufacturing industry and accelerate its clean energy transition.
