The Sun Earth DXM10-54H 525W is a 525 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 |
|---|---|---|---|
| DXM10-54H 505W | 505 W | 40.48 V | 15.65 A |
| DXM10-54H 510W | 510 W | 40.65 V | 15.7 A |
| DXM10-54H 515W | 515 W | 40.8 V | 15.75 A |
| DXM10-54H 520W | 520 W | 40.99 V | 15.8 A |
| DXM10-54H 530W | 530 W | 41.33 V | 15.9 A |
The most critical specs to match are: cell count (must be exactly 108), Voc close to 41.16 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 Sun Earth DXM10-54H 525W.
