Heterojunction (HJT) manufacturer Huasun Energy has released empirical data comparing HJT and BC modules from a China Testing & Certification International Group’s (CTC) facility in Haikou City, Hainan Province. The test project selected 210 mm HJT and 182 mm BC modules, with 8 modules each installed on a fixed mounting system in a single row. The empirical data spanning from October to December 2024 revealed that the HJT modules had a normalized 3-month power generation of 291.68 kWh/kW, while the BC modules had 283.26 kWh/kW. The HJT modules outperformed the BC modules by an average of 2.97% in terms of power generation per watt. According to Huasun, simulations using the PVsyst system suggest that the power gain with HJT modules will be even greater in summer, especially in high-temperature, high-humidity regions, where HJT can generate higher electricity output.
Earlier this month, Huasun Energy signed a framework agreement to provide 3 GW of high-efficiency HJT modules for Hongyang Group’s solar-storage-hydrogen-ammonia-methanol projects (see China Solar PV News Snippets).
Recently, LONGi reported CGC-verified results which found its Hi-MO 9 BC modules delivered a significant performance advantage over TOPCon modules (see China Solar PV News Snippets).
Perovskite manufacturer RenShine Solar has launched the construction of its GW-level perovskite manufacturing facility in Changshu City, Jiangsu Province. The project, which will see the company invest RMB 1.25 billion ($171.24 million), includes a GW-scale perovskite manufacturing facility, the company’s headquarters, and a global technology innovation center. According to the plan, the factory is expected to be completed and put into production by early 2026.
RenShine Solar has already established a 10 MW perovskite tandem pilot line and a 150 MW mass production line in Changshu. Renshine recently also announced that its mass-produced 30 × 40 cm large perovskite tandem module achieved a conversion efficiency of 26.12% (see China Solar PV News Snippets).
PV energy application development company Mellow Energy has announced that its perovskite-silicon 4-terminal tandem module, developed in collaboration with Zhuhai Hongjun New Energy, has successfully passed China Photovoltaic Testing Center (CPVT) certification. The module achieved a front-side efficiency of 24.68% and a back-side efficiency of 18.87%. The company says that this module benefits from dual light-absorbing layers, with a theoretical efficiency limit of up to 45%.
Meanwhile, Mellow Energy’s 1.2 x 1.6 m² double-glass modules have reached a conversion efficiency of 18.16%, following a TÜV Rheinland certified 17.9% in December last year.
Linyang Storage, the energy storage division of power plant developer, owner, and operator Linyang Energy, has signed a cooperation agreement with the Hong Kong Applied Science and Technology Research Institute (ASTRI). The partners aim to develop a high-reliability, high-efficiency energy storage conversion system (H2CS) for MW-level storage applications. The project’s goals include achieving precise control of battery clusters, preventing energy efficiency losses and safety risks caused by circulating currents between battery clusters, thus significantly extending battery life and reducing operational and maintenance costs. According to Linyang Storage, the project involves 3 core technologies: a battery cluster converter based on third-generation semiconductor technology, an optimized control strategy for flexible charge and discharge of battery clusters, and high-speed communication technology and integrated management algorithms that combine battery management systems, energy management systems, and energy storage converter heterogeneous data.
China's inaugural ‘PV + oxygen generation’ integrated project commenced operation this week at the Lianbao Yeze Scenic Area in Sichuan's Ngawa County, 3,300 meters above sea level. The project pioneers a sustainable solution to address chronic oxygen supply challenges in high-altitude regions through solar energy innovation.
The project combines 15 solar-powered carports with an intelligent oxygen production system, forming a self-sustaining cycle of clean energy generation and oxygen supply. Utilizing advanced air separation technology, the system produces 50 cubic meters of oxygen per hour, supported by a 72-hour energy storage backup to ensure uninterrupted supply during low-light conditions. With an annual PV power output of 2.3 million kWh, the facility powers oxygen generators round-the-clock while feeding surplus electricity to the grid, creating a revenue stream to maintain operations.
