The SpolarPV SPV565-TM10-144BD is a 565 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 |
|---|---|---|---|
| 570 W | 50.55 V | 14.26 A | |
| 575 W | 50.68 V | 14.33 A | |
| 580 W | 50.86 V | 14.4 A | |
| 585 W | 51.02 V | 14.47 A | |
| 590 W | 52.27 V | 14.53 A |
The most critical specs to match are: cell count (must be exactly 144), Voc close to 50.39 V (within ±5%), and temperature coefficient TcVoc close to -0.275%/°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 SpolarPV SPV565-TM10-144BD.
