On June 3, Dinto Solar unveiled its heterojunction (HJT) G12 PLUS 1/3-cut modules at SNEC Shanghai 2026. Designed to meet growing demand for higher power, greater efficiency, and application-specific solutions, the new series addresses residential, commercial & industrial, utility-scale, and vertical PV markets while showcasing the latest advances in the company's HJT platform.

The HJT G12 PLUS portfolio includes three module formats:
·128-cell: 475–495 W, 23.8–24.8% efficiency, optimized for residential and vertical installations.
·144-cell: 535–555 W, 23.7–24.6% efficiency, suited for commercial, industrial, and vertical applications.
·198-cell: 740–770 W, 23.8–24.8% efficiency, designed for commercial and utility-scale projects.

The multi-format portfolio enables customers to optimize solar module selection according to different project requirements and installation conditions.

Performance improvements are driven by a combination of G12 PLUS large-format wafers, 1/3-cut architecture, 0BB (zero busbar) HJT technology, negative-gap stringing (an advanced cell interconnection technique) and high-density encapsulation. Together, these innovations reduce optical shading and electrical losses while increasing active area utilization.

 
The modules deliver more than 30 W higher output and over 1% higher efficiency than conventional half-cut products. Active area utilization reaches 94.59%, with full-screen designs expected to increase the figure to 95.61%, providing an additional 5–10 W power gain.

At the cell level, advanced technologies including photonic sintering and optimized passivation further enhance performance. Photonic sintering reduces line resistance by 50%, while 0BB technology lowers silver consumption, minimizes shading, and shortens current collection paths, supporting both higher output and improved manufacturing yield.

The 1/3-cut architecture also enhances reliability by reducing operating current and internal resistance losses. This design lowers module temperature and mitigating hotspot risk. Outdoor testing showed surface temperatures up to 12.5°C lower than conventional modules. IFC flexible interconnection technology improves mechanical stability and manufacturing precision, while dual-layer encapsulation achieved zero microcracks in 288-hour HAST testing.

The modules retain the inherent advantages of HJT technology, including high bifaciality, excellent temperature coefficients, and superior low-light performance. Combined with butyl sealants and dual-coated glass, the design further enhances moisture resistance and long-term durability across residential, commercial, utility-scale, and vertical PV applications.

The launch of the HJT G12 PLUS 1/3-cut series further strengthens Dinto Solar’s high-efficiency HJT portfolio, delivering higher performance, improved reliability, and greater lifecycle value for customers worldwide.
