The RECOM RCM-580-7DBNF is a 580 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-550-7DBNF | 550 W | 50.21 V | 14 A |
| RCM-555-7DBNF | 555 W | 50.34 V | 14.07 A |
| RCM-560-7DBNF | 560 W | 50.47 V | 14.15 A |
| RCM-565-7DBNF | 565 W | 50.6 V | 14.23 A |
| RCM-570-7DBNF | 570 W | 50.74 V | 14.31 A |
| RCM-575-7DBNF | 575 W | 50.88 V | 14.39 A |
| RCM-585-7DBNF | 585 W | 51.16 V | 14.55 A |
| RCM-590-7DBNF | 590 W | 51.31 V | 14.63 A |
The most critical specs to match are: cell count (must be exactly 144), Voc close to 51.02 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-580-7DBNF.
