The LONGi LR7-72HGD-595M is a 595 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 |
|---|---|---|---|
| 585 W | 51.8 V | 14.25 A | |
| 590 W | 52 V | 14.33 A | |
| 600 W | 52.22 V | 14.49 A | |
| 605 W | 52.33 V | 14.57 A | |
| 610 W | 52.44 V | 14.65 A | |
| 615 W | 52.55 V | 14.73 A | |
| 620 W | 52.77 V | 14.85 A | |
| 625 W | 52.88 V | 14.93 A |
The most critical specs to match are: cell count (must be exactly 144), Voc close to 52.11 V (within ±5%), and temperature coefficient TcVoc close to -0.23%/°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 LONGi LR7-72HGD-595M.
