The Aiko Solar AIKO-A790-GRH78Dw is a 790 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 |
|---|---|---|---|
| 770 W | 58.72 V | 16.64 A | |
| 775 W | 58.82 V | 16.71 A | |
| 780 W | 58.92 V | 16.78 A | |
| 785 W | 59.02 V | 16.85 A | |
| 795 W | 59.22 V | 16.99 A | |
| 800 W | 59.32 V | 17.06 A | |
| 805 W | 59.42 V | 17.13 A |
The most critical specs to match are: cell count (must be exactly 156), Voc close to 59.12 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-A790-GRH78Dw.
