Key Features

• Rated power: 420 Watts (Pmax) under Standard Test Conditions

• Half-cut monocrystalline (or PERC / TOPCon) cell technology — improves shade performance, lowers current through each cellpiece → less heat and losses

• Efficiency around 21–22% typical for this class

• Open circuit voltage (Voc): ~ 37–38 V

• Voltage at max power point (Vmp): ~ 31–32 V; Current at MPP (Imp): ~ 13 A

• Short circuit current (Isc): ~ 13-14 A

• Power tolerance around 0 / +5 W

• Dimensions ~ 1722 × 1134 × 30 mm; weight ~ 20-25 kg depending on frame & cell type

• Durable build: tempered glass, anodized aluminum frame, IP-rated junction box, MC4 connectors

• Warranty: ~25 years linear power output + ~10-12 years materials/workmanship typical for good panels in this class
