The RECOM RCM-670-8DBRCM is a 670 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-635-8DBRCM | 635 W | 49.24 V | 16.45 A |
| RCM-640-8DBRCM | 640 W | 49.34 V | 16.54 A |
| RCM-645-8DBRCM | 645 W | 49.44 V | 16.62 A |
| RCM-650-8DBRCM | 650 W | 49.54 V | 16.7 A |
| RCM-655-8DBRCM | 655 W | 49.64 V | 16.78 A |
| RCM-660-8DBRCM | 660 W | 49.74 V | 16.86 A |
| RCM-665-8DBRCM | 665 W | 49.84 V | 16.95 A |
The most critical specs to match are: cell count (must be exactly 132), Voc close to 49.94 V (within ±5%), and temperature coefficient TcVoc close to -0.2%/°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-670-8DBRCM.
