The DAH Solar DHN-72X16/DG-FS(BW)-580W is a 580 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 |
|---|---|---|---|
| DHN-72X16/DG-FS(BW)-575W | 575 W | 51.2 V | 14.08 A |
| DHN-72X16/DG-FS(BW)-585W | 585 W | 51.6 V | 14.2 A |
| DHN-72X16/DG-FS(BW)-590W | 590 W | 51.8 V | 14.26 A |
| DHN-72X16/DG-FS(BW)-595W | 595 W | 52 V | 14.32 A |
Match the voltage, not the cell count or the wattage. The replacement's open-circuit voltage should be no more than 2 % above 51.4 V and its working voltage within 5 % of the original; its working current should not be more than 3 % lower, because the weakest panel in a string sets the current for all of them. A temperature coefficient closer to zero than -0.25 %/°C is fine — it adds less voltage in frost. The finder above screens the whole catalogue by these rules.
Yes, if its voltage matches. A higher-wattage panel of the same voltage simply has more current, and a string only carries as much as its weakest panel gives, so the extra goes unused at no risk to the string. Two things to check: its higher short-circuit current against the inverter's rating, and its frame, which is usually larger. The finder shows both; verify the pick in the String Compatibility Calculator with your inverter before installing.
If its Voc is higher, the string comes closer to the inverter's maximum voltage on frosty mornings, when voltage climbs by the TcVoc coefficient; if its Vmpp is lower, the string can drop out of the inverter's working range (MPPT) on hot days. The finder scores each difference only in the direction that hurts — a lower Voc or a flatter coefficient costs nothing — and ranks candidates by how closely they match the DAH Solar DHN-72X16/DG-FS(BW)-580W.
