The JA Solar JAM54D41-410/GB is a 410 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 |
|---|---|---|---|
| JAM54D41-415/GB | 415 W | 37.95 V | 14.02 A |
| JAM54D41-420/GB | 420 W | 38.08 V | 14.09 A |
| JAM54D41-425/GB | 425 W | 38.23 V | 14.16 A |
| JAM54D41-430/GB | 430 W | 38.32 V | 14.23 A |
| JAM54D41-435/GB | 435 W | 38.48 V | 14.3 A |
The most critical specs to match are: cell count (must be exactly 108), Voc close to 37.85 V (within ±5%), and temperature coefficient TcVoc close to -0.26%/°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 JA Solar JAM54D41-410/GB.
