Have a 2s2p array. 370W. Voc 48.82V, Isc 9.87A 4 panels total.
One panel needs replacement.
Was going to use 340W with Voc 46.6V, Isc 9.49A
So, one string will combine in series the 370 specs with 340 specs. The lowest current takes precedence, 9.49A.
The voltages differences of these dissimilar panels is minor, so is the current.
Our concern is MPPT tracking. How will this combo effect that given minor differences?
Your thoughts?
Thank you.
