There is “no perfect way”.

This data sheet will lay out some the data for you to make your decision with the equipment (solar panels & mppts) that you currently have.

PV MPPT

Watt = 365 150/60

VOC = 48.3

IscA = 9.7

VmppV = 39.88

ImppA = 9.17

Series / Parallel =% capacity of MPPT

2 / 2 = 85%

2 / 3 = 127%

1 / 3 = 64%

1 / 4 = 85%

1 / 5 = 106%

Series 

Increase Voltage

Amps Stay Same

Panels connect to each other in Daisy Chain Fashion

~Higher output under normal circumstance

Parallel

Amps Increase

Voltage Stays the same

Performs Better When part of the solar array is shaded or broken.

*need combiners

Increase the number of Inline Fuses needed.

If I thought I’d back the back of bus in shade or one side in the shade then I would do that section in parallel

If going 2/3 & 1/4.

Get

3 ) 30 a inline

2 ) 2:1 Y branch pair

1 ) 3:1 Y branch pair

1) MRBF Terminal

1) MRBF Fuse 300

Ultimately you will want to upgrade the battery cable. to Copper preferably the Tinned Copper I sell.
