The Perlight Solar PLM-415OM10A-44B is a 415 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 |
|---|---|---|---|
| PLM-400OM10A-44B | 400 W | 41.2 V | 12.41 A |
| PLM-405OM10A-44B | 405 W | 41.3 V | 12.53 A |
| PLM-410OM10A-44B | 410 W | 41.4 V | 12.65 A |
| PLM-420OM10A-44B | 420 W | 41.6 V | 12.92 A |
| PLM-425OM10A-44B | 425 W | 41.7 V | 13.03 A |
The most critical specs to match are: cell count (must be exactly 305), Voc close to 41.5 V (within ±5%), and temperature coefficient TcVoc close to -0.27%/°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 Perlight Solar PLM-415OM10A-44B.
