The Aiko Solar AIKO-A520-MCE60Db is a 520 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-A515-MCE60Db | 515 W | 45.1 V | 14.66 A |
| AIKO-A525-MCE60Db | 525 W | 45.3 V | 14.72 A |
| AIKO-A530-MCE60Db | 530 W | 45.4 V | 14.76 A |
| AIKO-A535-MCE60Db | 535 W | 44.98 V | 15.07 A |
| AIKO-A540-MCE60Db | 540 W | 45.08 V | 15.13 A |
| AIKO-A545-MCE60Db | 545 W | 45.18 V | 15.19 A |
| AIKO-A550-MCE60Db | 550 W | 45.28 V | 15.25 A |
The most critical specs to match are: cell count (must be exactly 120), Voc close to 45.2 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-A520-MCE60Db.
