The Trina Solar TSM-NEG21C.20-695 is a 695 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-NEG21C.20-700 | 700 W | 48.6 V | 18.32 A |
| TSM-NEG21C.20-705 | 705 W | 48.8 V | 18.36 A |
| TSM-NEG21C.20-710 | 710 W | 49 V | 18.4 A |
| TSM-NEG21C.20-715 | 715 W | 49.2 V | 18.44 A |
| TSM-NEG21C.20-720 | 720 W | 49.4 V | 18.49 A |
| TSM-NEG21C.20-725 | 725 W | 49.6 V | 18.54 A |
| TSM-NEG21C.20-730 | 730 W | 49.9 V | 18.58 A |
| TSM-NEG21C.20-735 | 735 W | 50.1 V | 18.62 A |
| TSM-NEG21C.20-740 | 740 W | 50.3 V | 18.66 A |
The most critical specs to match are: cell count (must be exactly 132), Voc close to 48.3 V (within ±5%), and temperature coefficient TcVoc close to -0.24%/°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-NEG21C.20-695.
