The Aiko Solar AIKO-A685-MDE72Dw is a 685 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 |
|---|---|---|---|
| AIKO-A650-MDE72Dw | 650 W | 54.9 V | 15.27 A |
| AIKO-A655-MDE72Dw | 655 W | 55 V | 15.33 A |
| AIKO-A660-MDE72Dw | 660 W | 55.1 V | 15.39 A |
| AIKO-A665-MDE72Dw | 665 W | 54.16 V | 15.45 A |
| AIKO-A670-MDE72Dw | 670 W | 54.26 V | 15.51 A |
| AIKO-A675-MDE72Dw | 675 W | 54.36 V | 15.57 A |
| AIKO-A680-MDE72Dw | 680 W | 54.46 V | 15.63 A |
| AIKO-A690-MDE72Dw | 690 W | 54.66 V | 15.75 A |
The most critical specs to match are: cell count (must be exactly 144), Voc close to 54.56 V (within ±5%), and temperature coefficient TcVoc close to -0.22%/°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 Aiko Solar AIKO-A685-MDE72Dw.
