Thermal Temperature Coefficients

Module performance degrades at elevated cell temperatures. N-Type TOPCon and HJT exhibit lower power loss in hot tropical climates compared to legacy PERC modules.

α (Isc)+0.045%/°CCurrent Coefficient

Tropical Climate Advantage:At a cell temperature of 65°C (+40°C above STC), this panel retains 88.4% of rated output.

Mechanical & Structural Durability

Certified resistance to hurricane-force wind loads, heavy snow pressure, and ice hailstone impacts.

Front Mechanical Load (Snow)5,400 Pa (550 kg/m²)

Rear Mechanical Load (Wind)2,400 Pa (245 kg/m²)

Hailstone Impact Resistance25 mm hail @ 23 m/s (82 km/h)

Max System Voltage1,500 V DC

String Sizing & MPPT Safety Verification Tool

Calculates safe series string length based on extreme winter low and summer high ambient temperatures.

IEC 62548 Standard

Winter Record Low Temp (°C)Raises Voc (Risk of overvoltage)

Summer Peak Temp (°C)Lowers Vmp (Risk of dropout)

Inverter Max DC Input (V)Usually 1000V or 1100V

Inverter Min MPPT Voltage (V)Usually 160V to 200V

Max Cold Voc per Module53.70 VAt -10°C ambient

Min Hot Vmp per Module35.42 VAt 70°C cell temperature

Recommended String Range6 – 18 PanelsPrevents winter overvoltage and summer MPPT dropout
