The SGN-590-BDG1 is a 590 W N-type monocrystalline bifacial solar panel built with dual-glass construction. Its rear side can add up to 30% more output on reflective surfaces, and the N-type cell design reaches up to 22.8% efficiency, so it needs less roof or ground space than lower-output panels. The dual-glass build is aimed at harsh heat, cold, snow and wind, and it carries a 12-year materials and workmanship warranty plus a 30-year linear performance warranty, with UL 61730 ETL certification and CEC listing. It suits homeowners and installers planning ground mounts or open-rack arrays where reflected light reaches the back of the panel; on a flush roof mount the bifacial gain largely disappears, and cheaper monofacial panels of similar wattage may serve as well.
