Heterojunction (HJT) solar manufacturer Huasun Energy has signed a framework agreement with renewable energy developer Hongyang Group for the supply of HJT modules. Under the agreement, Huasun will provide 3 GW of high-efficiency HJT modules for Hongyang Group’s solar-storage-hydrogen-ammonia-methanol projects. Hongyang Group is developing these solar-hydrogen-ammonia-methanol projects in Xinjiang’s Ili and Altay regions, with part of the installation adopting a vertical mounting approach which can leverage HJT technology’s high conversion efficiency and bifaciality, using its dual-peak power generation advantage to reduce midday grid impact and mitigate energy storage pressure. Huasun stated that this will be its first large-scale photovoltaic project exceeding 3 GW in supply, setting a new record for its project delivery scale.
Huasun’s recent shared field test data showed that its HJT modules achieved a 7.13% higher yield compared to back contact (BC) modules (see China Solar PV News Snippets).
Solar PV major LONGi has released empirical data on its Hi-MO 9 module, based on its second-generation BC technology. The test project is located in Yantai City, Shandong Province, where the annual average sunlight duration is between 2,200 and 3,000 hours, with annual irradiation ranging from 1,390 to 1,630 kWh/m². According to the data, LONGi’s Hi-MO 9 modules demonstrated an average power generation gain of 2.93% over TOPCon modules and 5.92% over HJT modules during the monitoring period from September to November 2024.
LONGi recently received a Leadership-level (A-) rating for water security for the first time, while maintaining a Management-level (B) rating for climate change for the second consecutive year (see China Solar PV News Snippets).
TOPCon solar cell manufacturer Yingfa Group has held an inauguration ceremony for its new headquarters in Nanjing City, Jiangsu Province. The company has simultaneously launched a RMB 2.5 billion ($342.47 million) project integrating hydrogen storage and charging, electronics manufacturing, and wind-solar hybrid R&D and production. As part of this initiative, a 150 MW AC fishery-solar hybrid PV power system is under construction, with grid connection expected by June 2026. Once fully operational and connected to the grid, the project is expected to generate 180 million to 230 million kWh of electricity annually.
The Ecology and Environment Bureau of Changji Prefecture, Xinjiang, has approved the environmental impact report for Changji Ruisheng Photovoltaic Technology Co., Ltd.’s (Ruisheng PV) 2 GW HJT module manufacturing facility. According to the report, Ruisheng PV plans to invest RMB 125.02 million ($17.12 million) to establish this production line in the region. In January 2024, local media outlet Changji Daily reported that Ruisheng PV is a wholly-owned subsidiary of Mingyang Group, a leading wind power developer in China that forayed into HJT solar cell and module manufacturing industry recently. Ruisheng PV reportedly intends to expand the project to 5 GW in the future.
The 1 GW Kaichi Photovoltaic Power Station, part of the Golmud Gas Power Plant Restart and its supporting renewable energy project, has been grid-connected. Developed by PetroChina, this initiative revitalizes the Golmud gas power plant, which had been shut down for a decade, by integrating 1 GW of solar power and 500 MW of wind power with a 300 MW gas power station, achieving a gas-to-renewable energy ratio of 1:5. This marks PetroChina’s first renewable energy project utilizing natural gas power generation as a supporting source. Once fully operational, the project is expected to deliver an average annual grid-connected power output of 19.845 billion kWh, saving 598,300 tons of standard coal annually and reducing CO₂ emissions by 1.7997 million tons per year.
