280W Monocrystalline Solar Panel PV Module for Home & Commercial Rooftop

Each step up this family adds open-circuit voltage rather than only current, so the 280 W module reaches 40.32 V — useful when you want to keep series strings short while still hitting a target array voltage. Technical specifications Maximum Power (Pmax) 280 W Open Circuit Voltage (Voc) 40.32 V Short Circuit Current (Isc) 8.83 A Voltage at Pmax (Vmp) 33.6 V Current at Pmax (Imp) 8.33 A Module Efficiency 20.53 % Power Tolerance 0, +4.99W Maximum System Voltage 700 V DC Max Series Fuse Rating 20 A Module Type 210M280 Solar Cells Mono crystalline 210*105mm (4*14Pcs) External Dimensions 1550*880*30mm Weight 14.09 kg Front Glass 3.2 mm tempered glass Frame Aluminum Junction Box IP67 Output Cables 100CM 4mm² Cable Connector MC4 Compatible Mechanical Load Front Side Max. 5400Pa, Rear Side Max. 2400Pa Pmax Temperature Coefficient -0.350%/°C Voc Temperature Coefficient -0.270%/°C Isc Temperature Coefficient +0.048%/°C Package Dimensions 1565*70*895mm Package Weight 30 kg Pieces per Package 2 Where it fits best 24 V systems with moderate daily loads Replacing older panels while keeping the same railing Arrays where high string voltage is a design constraint Questions buyers ask Why does voltage rise but current stay similar? The family uses the same cell current with more cells in series. That is why the 240 W through 360 W modules in this width share an 8.83 A short-circuit figure. Is this compatible with a 24 V PWM controller? A PWM controller would clip the extra voltage and waste i Sold on IPV ESSA (https://ipvsolar.com/products/280w-1550x880x30mm).
