The RECOM RCM-415-7DBNG 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 |
|---|---|---|---|
| RCM-410-7DBNG | 410 W | 37.73 V | 13.94 A |
| RCM-420-7DBNG | 420 W | 38.11 V | 14.07 A |
| RCM-425-7DBNG | 425 W | 38.3 V | 14.15 A |
| RCM-430-7DBNG | 430 W | 38.49 V | 14.23 A |
| RCM-435-7DBNG | 435 W | 38.67 V | 14.31 A |
| RCM-440-7DBNG | 440 W | 38.85 V | 14.38 A |
The most critical specs to match are: cell count (must be exactly 108), Voc close to 37.92 V (within ±5%), and temperature coefficient TcVoc close to -0.25%/°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 RECOM RCM-415-7DBNG.
