Our main business is R&D, production and sales of PV modules. A base intergating the function of R&D and intelligent manufacturing is built in Jiangyin, Wuxi. After the Phase I(2023) & II(2024) being put into stream, the annual production capacity will reach 16GW of ultra-high efficiency solar modules. In the future, once the phase III of Jiangyin base finished, the overall capacity could reach 35GW.

Non-destructive cutting technology is introduced into HY SOLAR production line. Firstly, cut notches with width of about 1mm at both ends of the cell followed by low-temperature laser technology. The local heated region is cooled by cooling water, then there is stress difference on the surface of the cell piece for automatically being broken into two halves.
SMBB tech is adopted in HY SOLAR HT series modules, and 16 bus bars in total are applied on cells. The more grid lines there are, the thinner they become, which can reduce the shading area on cells, and greatly reduce the power loss caused by micro cracks, improving the power by more than 1.5% compared with the 5BB.
In the process of cell string layup, high-density cell encapsulating is applied, reducing the cell spacing from the 2.0mm(in traditional manner) to 0.8mm, realizing the micro-distance interconnection of the cells. By shortening the space between the cells, it can improve the effective power generation area of the module, thus improving the efficiency.
The automatic welding equipment adopted by HY SOLAR has excellent properties, with the advantages of high-speed cycle time (≤15s), wide deviation correction range (±30 mm,cell accuracy ≤0.3 mm), cutting single aging fast (30 min-50 min), bus bar feeding non-stop and virtual welding detection function, ensuring that the bus bar welding process can be completed with high efficiency and quality.
The intelligent EL test equipment adopted by HY SOLAR can synchronously carry out detection on both sides of module products, greatly improving the detection efficiency, and the core algorithm of deep learning greatly improves the accuracy of defect identification, as well as provides powerful guarantee for the high-performance of HY SOLAR module products.
The laid cell and other main materials are put into a fully automatic laminator. The equipment exhausts the air in the modules by vacuumizing, then heats to melt the adhesive film, and finally pressurizes the cells, glass and the adhesive film together, and takes out the modules after the temperature cools down.
The automatic welding junction box equipment used in the production line can quickly locate the position of the junction box and module busbar through the visual system, so as to guide the welding head to weld accurately, and the whole operation process is fast and efficient.
The four-wire method is adopted for the IV test of HY SOLAR production line, and the results obtained are more accurate than the traditional two-wire method. The performance data obtained is also usually displayed on the back of the HY SOLAR module data sheet as an important description of the module performance.
