The AXITEC AC-325MH/120V is a 325 W solar panel. Finding a compatible replacement requires matching the original electrical characteristics — particularly Voc, Vmpp, Isc, and temperature coefficients — to ensure safe operation within the same string.
Use the form above to find panels that match these specifications. Then verify the replacement in the String Compatibility Calculator with your inverter.
| Model | Power | Voc | Isc |
|---|---|---|---|
| AC-315MH/120V | 315 W | 40.13 V | 10.03 A |
| AC-320MH/120V | 320 W | 40.25 V | 10.11 A |
| AC-330MH/120V | 330 W | 40.49 V | 10.25 A |
| AC-335MH/120V | 335 W | 40.65 V | 10.31 A |
| AC-340MH/120V | 340 W | 40.82 V | 10.39 A |
The most critical specs to match are: cell count (must be exactly 120), Voc close to 40.37 V (within ±5%), and temperature coefficient TcVoc close to -0.29%/°C. If Voc differs significantly, the string voltage at extreme temperatures may shift outside the inverter's MPPT range. The replacement finder above pre-screens all candidates by these criteria.
A higher wattage panel usually has a higher Vmpp or Isc, which can affect string voltage and current. Small increases (up to 10–15%) are typically safe if the other electrical specs align. The replacement finder shows a compatibility score — 'Exact match' means the specs align closely. Always verify the replacement in the String Compatibility Calculator with your inverter before installation.
If the replacement has a significantly different Voc or Vmpp, the string voltage may shift outside the inverter's MPPT range, reducing energy production or causing faults. This effect is amplified at temperature extremes: at low temperatures, voltage rises by the TcVoc coefficient. The replacement finder automatically accounts for this — it scores candidates by how closely the electrical specs match the original AXITEC AC-325MH/120V.
