There are many variables to answer the OPs question of one large vs more smaller panels. I suspect that many current systems start small and then upgrade which effects their choices.
I did 2 calculations for my rig with roof space being a constraint. Note that limited roof space is not a given as panels can be mounted above vents and ACs, but few do this.
2x 270W 65*39” Solar Blvd panels and MS MPPT 60 controller: 540W, 35 sq ft, $2.56/W cost.
4x 140W 59*27” Solar Blvd panels and MS PMW 60 controller: 560W, 44 sq ft, $2.28/W cost.
Roof space is limited to the 4 parallel panels but I might be able to use a smaller controller.
This included all hardware and wiring, DIY project, no panel shipping costs which are pricey .
However given the above two I’d choose the 270W panels especially because I can add a third panel.
3x 270W 65*39” Solar Blvd panels and MS MPPT 60 controller: 810W, 53 sq ft, $1.96/W cost.
