The Risen RSM150-8-500M is a 500 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 |
|---|---|---|---|
| RSM150-8-485M | 485 W | 50.35 V | 12.25 A |
| RSM150-8-490M | 490 W | 50.57 V | 12.32 A |
| RSM150-8-495M | 495 W | 50.79 V | 12.39 A |
| RSM150-8-505M | 505 W | 51.23 V | 12.53 A |
| RSM150-8-510M | 510 W | 51.45 V | 12.6 A |
The most critical specs to match are: cell count (must be exactly 150), Voc close to 51.01 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 Risen RSM150-8-500M.
