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) | 445 | 336 | Wp |
| Voltage at Maximum Power (Vmp) | 32.96 | 30.82 | V |
| Current at Maximum Power (Imp) | 13.5 | 10.9 | A |
| Open-Circuit Voltage (Voc) | 39.95 | 37.63 | V |
| Short-Circuit Current (Isc) | 14.21 | 11.44 | A |
| Module Conversion Efficiency | 22.3% | 21.0% | % |
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.

Hardware Compatibility & String Inverter Pairing
Each listed inverter is electrically validated below from published specs — string windows, failures, and unverifiable gaps shown as-is. Cold design −10°C, hot design 60°C.
No verified window
- UNVERIFIED — Cold Voc vs max DC: Cannot verify — inverter max DC input voltage unpublished.
- PASS — Hot Vmp vs MPPT floor: Vmp at 60°C ≈ 39.6 V/panel → min 1 in series for the 25 V MPPT floor.
- UNVERIFIED — String current: Cannot verify — panel Isc unpublished or no valid string window.
- ASSUMPTION — No Voc-specific temperature coefficient published — Pmax coefficient (-0.3%/°C) used as proxy.
- ASSUMPTION — Cold design -10°C, hot design 60°C. Confirm against the datasheet for your site.
