Key features:
• Heterojunction technology: Combines crystalline silicon with thin-film silicon layers to convert sunlight into electricity.
• Gapless half-cell layout: Reduces unused space between cells while retaining the clean all-black appearance.
• Rated 420 W output: 21.8% module efficiency helps compare the panel’s output with its roof area.
• Low-current design: Supports system design with compatible inverter inputs; the full voltage and current limits still need to be checked.
