Seraphim displayed its latest full-screen 620 W Sable series bifacial PV module at the exhibition
This model, featuring an innovative steel frame that acts as a steel ‘cover’, is equipped with a 26 mm-high aluminum frame only in sections along the length of the module
Its innovative framing process steps during the pre-lam and lamination stages eliminate the need for conventional framing process steps post-lamination
The TaiyangNews team had the opportunity to visit Seraphim’s booth at Intersolar Europe 2025 and gain some insights into the company’s innovative Sable Series full-screen bifacial module, among others.
According to the company's datasheet, the Sable Series SRP-xxx-BTC-BG model is available in 6 power classes, ranging from 605 W to 630 W. At the show, the company showcased the 620 W variant, which features 132 half-cut TOPCon cells (M12R, 182 × 105 mm). This module delivers a power output of 620 W with an efficiency of up to 22.95%, with a bifaciality of up to 80% (±5%).
Measuring 2,382 × 1,134 × 26 mm and constructed with 2 mm-thick glass on both the front and rear, the module weighs 32.5 kg, making it suitable for utility-scale applications. Seraphim has developed an innovative framing design to address the need for greater reliability and durability, while maintaining cost efficiency.
The company has enhanced the pre-lamination process by integrating a stainless steel frame, forming a robust ‘cover’ that is fused with a 26 mm-high aluminum frame during lamination. Unlike conventional modules that use a continuous frame around all 4 sides, Seraphim’s frame is applied only to sections along the length of the module, simplifying installation. This novel manufacturing approach also eliminates the need for a separate framing step after lamination.
Additionally, the steel cover acts as a full-screen front, such as the front screen of a smart phone, providing anti-soiling and anti-water accumulation benefits. To ensure performance in harsh environments, the module is certified to withstand snow loads up to 5,400 Pa and wind loads up to 2,400 Pa.
Seraphim offers a 15-year product and a 30-year performance warranty for the Sable Series module.
