The Waaree Energies BiN-03-690 is a 690 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 |
|---|---|---|---|
| 680 W | 47.78 V | 18.16 A | |
| 685 W | 47.98 V | 18.2 A | |
| 695 W | 48.38 V | 18.27 A | |
| 700 W | 48.58 V | 18.31 A | |
| 705 W | 48.77 V | 18.36 A | |
| 710 W | 48.97 V | 18.39 A | |
| 715 W | 49.17 V | 18.42 A |
The most critical specs to match are: cell count (must be exactly 132), Voc close to 48.18 V (within ±5%), and temperature coefficient TcVoc close to -0.26%/°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 Waaree Energies BiN-03-690.
