The Trina Solar TSM-385DE08M.08(II) is a 385 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 |
|---|---|---|---|
| TSM-360DE08M.08(II) | 360 W | 40.7 V | 11.24 A |
| TSM-365DE08M.08(II) | 365 W | 41 V | 11.3 A |
| TSM-370DE08M.08(II) | 370 W | 41.3 V | 11.37 A |
| TSM-375DE08M.08(II) | 375 W | 41.6 V | 11.45 A |
| TSM-380DE08M.08(II) | 380 W | 41.9 V | 11.52 A |
The most critical specs to match are: cell count (must be exactly 120), Voc close to 41.9 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 Trina Solar TSM-385DE08M.08(II).
