SF1-540W Solar Panels Monocrystalline Half Cell Panel

Based on leading multi-busbar technology, the Singfo modules adopt the Large-sized silicon wafer, non-destructive cutting and high-density interconnect technologies, which allow it to reach high power output and high module efficiency. By virtue of low-voltage and higher module string power output, it unlocks huge potential for further reducing balance-of-system costs.
