The RECOM RCM-625-7DBNN is a 625 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-610-7DBNN | 610 W | 55.1 V | 14.11 A |
| RCM-615-7DBNN | 615 W | 55.3 V | 14.16 A |
| RCM-620-7DBNN | 620 W | 55.5 V | 14.21 A |
| RCM-630-7DBNN | 630 W | 55.9 V | 14.31 A |
| RCM-635-7DBNN | 635 W | 56.1 V | 14.36 A |
The most critical specs to match are: cell count (must be exactly 156), Voc close to 55.7 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-625-7DBNN.
