The DMEGC DM735G12T-B66HSW is a 735 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 |
|---|---|---|---|
| DM710G12T-B66HSW | 710 W | 48.82 V | 18.52 A |
| DM715G12T-B66HSW | 715 W | 49.02 V | 18.56 A |
| DM720G12T-B66HSW | 720 W | 49.2 V | 18.6 A |
| DM725G12T-B66HSW | 725 W | 49.38 V | 18.65 A |
| DM730G12T-B66HSW | 730 W | 49.56 V | 18.7 A |
The most critical specs to match are: cell count (must be exactly 132), Voc close to 49.74 V (within ±5%), and temperature coefficient TcVoc close to -0.25%/°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 DMEGC DM735G12T-B66HSW.
