Help with wiring and setup of 3x395w panels on MPPT 150/60

Hi all

I am in the process of installing 3 x 395watt solar panels on my boat, these will be over an arch in the transom, and the panels will not be completely flat.


AS395M6-120
Rated Maximum Power at STC 395W
Open Circuit Voltage (Voc) 42.1
Maximum Power Voltage (Vmp) 35.62
Short Circuit Current (Isc) 11.63
Maximum Power Current (Imp) 11.09
PV Module Efficiency (%) 21.65


For the controller I have a Victron 150/60 located 5 meters away from the panels, and based on my calculations, the total voltage will not reach the 150v threshold

I live in Hong Kong, so temperatures never go below 5 centigrade, and seldom below 10 centrigrade


I have been reading the benefits of panels in series over parallel, but given the fact that the panels will not be totally level to one-another, what is the expert recommendation?

I was keen on series, in order to benefit or using a smaller wire size, although if in parallel, I will run independent wires to a bus bar just before the MPPT


Any feedback will be welcomed


Thank you for your help

Regards
Andres
