Are these panels compatible on the same string?

My current panels are discontinued (in orange) and I want to find some panels with similar characteristics for the same string (series). These (in blue) are the closest I can find. Does anyone think this will be an issue? Currently have 6 of the Orange in a string and want to add 4 more.






Not too worried about efficiency, my main concern is safety. I just need a few more panels for a few more watts.

I think that should work.

10 panels will be 410V nominal, OK if MPPT is rated for 500V or higher max input.

Are the connectors same brand? If different, suggest you make an extension cable with connectors at each end that match panel they will connect to.
And do similar for the pigtails or home run wires.

DC INPUT VOLTAGE RANGE 100-600
MPPT OPERATING VOLTAGE RANGE 140-500 VDC
NOMINAL MPPT VOLTAGE 360 VDC

It's above the nominal and not at the Max operating so I believe I may be fine.
Not sure if the connectors are the same but I was planning to cut all and replace with extra I have, to ensure compatibility.

Just FYI for any reading this....I had two 60 cell and two 72 cell panels. They were of the same type, looked the same only the 72 cell were longer. The max power amps were very near the same between the two types of panels. In a series circuit, all components have the same current (not equal but the same). So the 60 cell in series with the 72 cell can be loaded to max power and both panels will be producing well. My four panels are one 60 and one 72 cell panel in series, with two of those strigs in parallel. This works well on a 100v max charger.

Matching the peak amps helps get the most power from your string.
