The German manufacturer said that his completely black contact panel with back contact has a power conversion efficiency up to 23.52%.
The German solar manufacturer Solar-Labrik has introduced its first sunscreen contact (BC) solar module, the Mono S4 Half-Cut BC Full Black, designed for residential and commercial and industrial (C&I) applications.
The 480 W panel is built with 108 half cells based on n-type monocrystalline silicon waffles and achieves a conversion efficiency of 23.52%. It measures 1,800 × 1,134 mm, weighs approximately 25 kg and is framed in 30 mm black anodized aluminum. The module is equipped with Stäubli’s MC4 EVO 2 connectors and supports a system voltage of up to 1500 V.
The new product uses a double glass construction with 2 mm glass on both sides, which improves durability and increases the resistance to microsprides, according to the manufacturer. The panel can resist snow loads of up to 5,400 PA and is certified for Hail Protection Class 4.
By moving all electrical contacts to the back of the cell, Solar-Fabrik says that the module benefits from a cleaner front surface and a higher efficiency. The company has also implemented what it calls an “anti-shadow design” using flexible current paths, which prevent full cell series from being eliminated under partial shadow.
Electric characteristics include an MPPT voltage of 33.4 V, an MPPT stream of 14.2 A, an open circuit voltage of 40.4 V and a short-circuit current of 14.9 A. The operating temperature range is specified at –40 ° C to +85 ° C, with a temperature coefficient of –0.260%/° C.
Solar-Fabrik supports the module with a 30-year product warranty and a 30-year-old linear performance guarantee, which guarantees 88.5% of the nominal output at the end of the term.
