On Day 2 of the recently held Intersolar Europe 2025 exhibition, 3SUN launched its latest 3SUNB60 series module, powered by its CORE-H technology. 3SUN is part of the Enel Group, with HJT cell and module factories in Catania, Italy. This new product features made-in-Europe HJT cells, assembled in a European factory. The company also displayed other products at its booth.
According to 3SUN, its CORE-H HJT cell technology combines 2 types of silicon: crystalline silicon, known for its highly ordered cubic atomic structure, and amorphous silicon, which has a disordered atomic arrangement. This combination enhances energy conversion efficiency compared to conventional silicon solar cells. Additionally, the technology offers a low temperature coefficient, enabling the module to maintain strong performance even under extreme temperatures and harsh environmental conditions.
Latest Launch
Given the limited technical details disclosed, insights can be drawn from the datasheet of its commercially available counterpart, the 3SUNB60 LE, whose cells are fabricated outside the European Union (EU).
The newly launched 3SUNB60 module features 120 G12-size HJT half-cut cells and boasts a maximum power output of 640 W. Efficiency numbers, however, remain undisclosed. Designed for high-voltage systems, it operates at up to 1,500 V DC. Thanks to the symmetrical structure of its HJT cells, the module offers bifaciality of up to 90%. Its temperature coefficient is improved at –0.24%/°C, compared to –0.26%/°C in the LE version. Laminated with 2 mm-thick front and rear glass in dimensions of 2,172 × 1,303 × 35 mm, this module weighs 36 kg.
This module comes with a performance warranty of up to 30 years.
Future Products
Alongside the latest launch, the company showcased its upcoming short-format glass-glass module, 3SUNB48, equipped with Made-in-Europe cells and assembled in Europe. Designed with a black frame for aesthetic appeal, it offers a power output range of 490 W to 510 W, targeting the distributed generation (DG) market in Europe.
Another upcoming model, the 3SUNB66, was also on display. Equipped with 132 HJT cells based on the 2nd-generation CORE-H technology, this module is expected to deliver a power output of up to 730 W. The company is set to launch this module in 2026.
