About Grand Sunergy
Founded in early 2022, Grand Sunergy is a leading company specializing in the Research & Development, manufacture, and sales of high efficiency HJT photovoltaic cells and modules. The company has established two production bases, one module plant in Huaibei City, Anhui Province, and one HJT cell production facility in Xuzhou City, Jiangsu Province. In order to provide customers rich choices, Grand Sunergy also involves in the production of the traditional P-type Mono Perc series.
Grand Sunergy has formed an industry leading scientist and expert team, with full dedication and capacity to the Research and Development of HJT technology that will be transferred to mass production to create best value for end customers.

- 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
1% first year degradation of HJT cells, 0.375% for each successive year, significantly lower than 2% and 0.45% of bifacial PERC cells
1.9%-2.9% higher full life cycle power generation of HJT cells than bifacial PERC cells
