Dual Electrical Specifications: STC vs NMOT
Standard Test Conditions (1000 W/m², 25°C, AM1.5) vs Nominal Operating Conditions (800 W/m², 20°C, 1 m/s wind)
| Electrical Parameter | STC (estimated) | NMOT (estimated) | Unit |
|---|---|---|---|
| Maximum Peak Power (Pmax) | 550 | 415 | Wp |
| Voltage at Maximum Power (Vmp) | 40.74 | 38.09 | V |
| Current at Maximum Power (Imp) | 13.5 | 10.9 | A |
| Open-Circuit Voltage (Voc) | 49.38 | 46.52 | V |
| Short-Circuit Current (Isc) | 14.21 | 11.44 | A |
| Module Conversion Efficiency | 21.7% | 20.4% | % |
Vmp, Imp, Voc and Isc are estimated from Pmax using standard module ratios until the datasheet is checked.
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.
