About GrandSunergy
Grandsunergy specializes in the production of heterojunction cells and modules, as well as project investments and operation of the entire supply chain. With a top-tier professional research team and advanced technological pathways, the company stands as a leading enterprise in China’s new energy industry. The company has successfully established five major production bases in Xuzhou, Jiangsu Province, Huaibei, Anhui Province, Huainan, Anhui Province, Suzhou, Anhui Province, Zhangjiakou, Hebei Province, and is currently accelerating the construction of bases in Tangshan, Hebei Province, Laizhou, Shandong Province. The company plans to establish industry chain clusters with a market value of 100 billion and build projects of silicon materials, crystal pulling, ultra-thin N-type silicon wafers, high-efficiency heterojunction cells, large-sized component and sodium ion energy storage. It also intends to develop high-efficiency hybrid wind-solar-storage power stations. Meanwhile, we invest in Building Integrated Photovoltaics (BIPV) and projects of multi-microgrids (source-grid-load-storage), creating a new generation of photovoltaic ecological industry chain, striving to lead the new energy industry. In September 2023, Grandsunergy completed the acquisition of the listed company Beijing Qianjing Landscape Co.,Ltd (Stock Code: 603778) holdings. Grandsunergy initiated the investment path of “dual main businesses” of ecological governance and new energy with a new platform.

- Technology of HJT
- HJT Series
- PERC Series
Technology Advancements of HJT Modules
Higher Bifaciality / 85%+ bifaciality
10%-20% back irradiation and higher bifaciality contribute to 2%-4% higher power generation per watt of HJT cells than bifacial PERC cells
Temperature Coefficient / -0.26%/℃
-0.26%/℃ heating coefficient of HJT cells, with 0.13%/℃ advancement
0.6~3.9% higher power generation per watt of HJT than bifacial PERC
NO PID NO LID / high reliability
No LID caused by B-O effect, outstanding PID resistance by TCO film, to best guarantee long-period durability and yield
Weak Light Performances / high energy yield
HJT cells use N-type monosilicon wafer, PERC cells use P-type monosilicon wafer
weak light effect increases power generation per watt of HJT cells by 0.5-1% than bifacial PERC cells
LCOE / best LCOE
a cutting-edge and most prominent technology to best reduce LCOE
Low Degradation / low degradation rate
