Solyco releases 500 W full-black back contact solar module with 24.5% efficiency

German manufacturer Solyco Solar AG has introduced a new module series combining n-type back-contact (BC) cell technology with a full-black glass-glass design aimed at premium residential and commercial rooftop installations.

“The innovative rear-side cell interconnection reduces front-side shading losses and enhances performance under partial shading conditions,” the company’s Marketing Manager, Jussi Larkovuo, told pv magazine. “The completely black design enables seamless architectural integration and a sophisticated roof appearance.”

The Solyco Design R-BG 108nBC.7/485-500 solar modules are available in four power classes from 485 W to 500 W, with the top variant reaching a conversion efficiency of 24.5% across a module area of 2.04 m².

The series uses 108 monocrystalline n-type back-contact half-cells, measuring 182 mm × 98 mm, and features a bifacial nameplate irradiance (BNPI) rating of 526 W to 542 W with a bifaciality factor of up to 75%. The dual-glass construction consists of 2 mm tempered front and rear glass, combined with a black anodized aluminum frame, resulting in a 24.8 kg module equipped with Stäubli MC4-Evo 2 connectors and 4 mm² solar cables.

The modules feature a temperature coefficient of -0.26%/°C and are designed for operation between -40 C and 85 C. They support a maximum system voltage of 1,500 V and have been tested for mechanical loads of up to 5,400 Pa on the front side and 2,400 Pa for wind suction. Additional certifications include Class HW3 hail resistance, Class A fire performance under UL 790, Broof(t1) roof fire classification according to DIN EN 13501-5:2016, and resistance testing under IEC 61701:2020 for salt mist and IEC 62716:2020 for ammonia exposure.

Solyco provides a 30-year product warranty and a 30-year linear performance warranty backed by a German warranty provider. The performance guarantee ensures 99.0% of initial output after the first year and at least 88.85% after 30 years.
