The Chinese manufacturer launched two new module series for utility-scale applications. The new products have a temperature coefficient of -0.24% per C and a bifaciality factor of more than 85%.
Chinese heterojunction (HJT) solar module manufacturer Huasun this week launched two new series of solar panels for ground-mounted PV applications.
The company said the new products feature zero-busbar (0BB) technology. “Huasun’s approach mainly involves welding and dispensing, combining benefits such as stronger adhesion, improved hot spot resistance and elimination of carrier film,” the company said in a statement. “Huasun uses a simpler two-step screen printing (SP) technology to deliver superior product quality and improved electrical and cell-to-module (CTM) performance, demonstrating significant advantages over super multi-busbar (SMBB) products in terms of open circuit voltage, conversion efficiency and module power.”
“Huasun’s 0BB modules use faceplate welding, which offers benefits such as reliable soldering and reduced contact resistance,” said Christian Comes, Huasun’s director of business development in Europe. “Additionally, the design reduces metal coverage at the rear, increasing the light-receiving area and achieving bifaciality of up to 90%,”
The larger of the two product lines is the Himalaya G12 series, which includes five variants with output power ranging from 720W to 740W and an energy conversion efficiency of g from 23.18% to 23.82%. The no-load voltage is between 49.79 V and 50.43 V and the short-circuit current is between 17.93 A and 18.17 A.
The panels feature 132 half-cut monocrystalline HJT cells, measuring 2,384 mm x 1,303 mm x 33 mm and weighing 38.7 kg.
The other product line is the Everest G12R Series, available in five variants with a power from 615 W to 635 W and an efficiency ranging from 22.77% to 23.51%. The no-load voltage is between 49.75 V and 50.39 V and the short-circuit current is between 15.44 A and 15.70 A.
These modules also feature 132 half-cut monocrystalline HJT cells. They measure 2,382mm x 1,134mm x 30mm and weigh 32.6kg.
Both products can operate with a maximum system voltage of 1,500 V and feature an IP68 housing with anodized aluminum frames. They have a temperature coefficient of -0.24% per C and their operating temperature ranges from -40 C to 85 C. Both sides of the bifacial modules are covered with 2.0 mm glass.
The new products come with a 30-year linear performance warranty and a 15-year product warranty. The degradation in the first year is reported to be 1.0% and the final power over 30 years is guaranteed to be not less than 88% of the rated output power.
“Huasun has significantly improved the electrical, optical and temperature coefficient performance of HJT modules, improving the competitiveness of its product range in the market,” the company said.
