Depends.
What size battery bank, in amps? (Also, lithium vs lead acid batteries?)
What size solar panel, in watts?
How much power, in amps, will you be using daily?
Will you be parked in full sun or shade?
What latitude are you in, say southern Florida vs northern Maine? (OK, that last one I know, your being in Canada and all. I put it in for others who may read this thread later with the same question.)
I just spent 10 days boondocking in Jackson Center, Ohio. I have 180 watts of solar on my roof. I was in full sun all day. I only had to use my generator once to recharge my batteries. That was due to a couple of days of heavy overcast/rain.
