The Ulica Solar UL-635M-132DHVN is a 635 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 |
|---|---|---|---|
| UL-610M-132DHVN | 610 W | 46.54 V | 15.96 A |
| UL-615M-132DHVN | 615 W | 46.72 V | 16.02 A |
| UL-620M-132DHVN | 620 W | 46.9 V | 16.12 A |
| UL-625M-132DHVN | 625 W | 47.08 V | 16.19 A |
| UL-630M-132DHVN | 630 W | 47.25 V | 16.25 A |
The most critical specs to match are: cell count (must be exactly 132), Voc close to 47.45 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 Ulica Solar UL-635M-132DHVN.
