Heterojunction manufacturer Risen Energy has announced that the average power output of its HJT-based Hyper-ion series modules in mass production has officially surpassed 740 Wp. The HJT cells used in the modules have been certified by the Fujian Institute of Metrology to achieve a conversion efficiency of 26.61%.
Risen claims that it has reduced the silver consumption for HJT cells to 5 mg/W, which is 37.5% lower than mainstream TOPCon products. The company added that it has also optimized non-silicon costs by leveraging screen-printing technology, achieving a low 1.8% module encapsulation loss and keeping the cell breakage rate below 0.03%.
Recently, Risen’s Hyper-ion module received the Best Energy Yield Award from SGS following extensive field performance testing in Saudi Arabia (see China Solar PV News Snippets).
Leading solar manufacturer LONGi has announced that it will allocate RMB 1.08 billion ($150 million) from the proceeds of its 2021 convertible bond issuance to increase the capital in its subsidiary Tongchuan LONGi through a wholly owned subsidiary. The funds will be used to support the implementation of a 12 GW high-efficiency monocrystalline cell facility.
Announced in May 2025, the facility is located in Tongchuan, Shaanxi Province, with a total planned investment of RMB 2.877 billion ($399.58 million). It is expected to start production in August 2025 and reach full capacity in Q1 2026. LONGi stated that it aims to ensure smooth implementation and improve the capital efficiency of this project through this capital injection.
On the expansion front, LONGi announced a solar PV manufacturing partnership with Pertamina in Indonesia to develop a 1.6 GW solar panel factory in the country (see LONGi, Pertamina Partner For 1.6 GW Solar Module Plant In Indonesia).
SANY Group subsidiary Sany Silicon has officially commissioned a 2 GW solar module manufacturing facility in Bazhong, Sichuan Province, its third integrated solar PV production base in China. Construction on the facility began in August 2024, with the first batch of modules rolling off the line at the end of June 2025 (see China Solar PV News Snippets). The factory primarily produces double-glass TOPCon modules with power ratings ranging from 430 to 680 W.
According to local reports, Phase II of the facility will focus on centralized PV power generation, distributed solar systems, centralized wind power, energy storage stations, smart microgrids, and a green electricity trading center.
Sveck, a manufacturer of solar photovoltaic encapsulation materials, is constructing a new facility in Heshan, Guangdong Province, with an annual PV encapsulation film production capacity of 200 million m². The company is investing a total of RMB 128 million ($17.78 million) in this facility that is spread over an area of 36,800 m². The main factory structure was topped out in April 2025, and this month, the local Development and Reform Bureau approved the project’s energy efficiency report.
Sveck listed encapsulants in both EVA and non-EVA categories of the TaiyangNews Backsheets & Encapsulant Market Survey 2024/25 published earlier this year, which can be downloaded for free here.
PowerChina Hydropower Development Group has commenced construction of the Xiaojinchuan River Basin Solar Base in Xiaojin County, Aba Prefecture, Sichuan Province. The RMB 700 million ($97.22 million), 160 MW project is described as China’s first integrated hydro–solar–pumped storage project.
Located at an average altitude of 3,700 meters, the site will include a 16 MW / 32 MWh battery storage facility. It is scheduled for full grid connection by the end of 2025. The project leverages existing hydropower and pumped storage infrastructure to create a ‘hydropower + solar + variable-speed pumped storage’ tri-level hybrid system, enabling real-time coordinated control. The project is expected to generate 280 GWh of electricity annually.
