Solar panels in series, add one parallel

[kurnikov]

I have nine panels installed on the roof.
Due to the maximum value of the electric voltage of the loop, eight panels are connected in series.
Can I connect a ninth panel in parallel to one of the eight panels in the series?

Panels:
Jinko 530W
Open-circuit Voltage (Voc): 49,26 V
Short-circuit Current (Isc): 13,71 A

Inverter MPPT max: 430 VDC

Under normal conditions there would be no advantage and no extra yield. If there was shading in the area where the two panels are in parallel there may be an advantage.
In a series string the current is limited to that through a single panel or path through the string.

So in full sun I don't gain any extra watts?

Correct
