The Canadian Solar CS7N-655MS is a 655 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 |
|---|---|---|---|
| CS7N-645MS | 645 W | 44.8 V | 18.35 A |
| CS7N-650MS | 650 W | 45 V | 18.39 A |
| CS7N-660MS | 660 W | 45.4 V | 18.47 A |
| CS7N-665MS | 665 W | 45.6 V | 18.51 A |
| CS7N-670MS | 670 W | 45.8 V | 18.55 A |
| CS7N-675MS | 675 W | 46 V | 18.59 A |
The most critical specs to match are: cell count (must be exactly 132), Voc close to 45.2 V (within ±5%), and temperature coefficient TcVoc close to -0.26%/°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 Canadian Solar CS7N-655MS.
