You can wire as many panels together as you like. There's no limit. You do have to do it properly, keeping in mind the voltage and amperage limits of your charge controller. You will also need proper fusing for multiple parallel panels.
I don't know if you've done much pricing research but you can probably buy a 120 watt panel for about the cost of 2 or 3 20 watt panels.
X2. Find a spot that a single 120 to 140W panel will fit. Morningstar 10amp sunsaver controller. About 200 bucks plus the wire to run. Custom make yourself some mounts to accommodate the curved roof.
Multiple tiny panels will work but it is multiple times the cost and more holes in your roof.
