Solar or Generator for Boondocking

This is for a truck camper, no a/c. This would be to keep batteries charged. I was putting together a solar kit (on paper, for purchase at a later date) and started thinking about a generator and whether that is a more efficient/effective solution.

I live in the PNW and some of the solar mfg./retailers state there is less sunlight, so the solar panels will be less efficient than in other parts of the country. I was going to put together a 200watt system, probably roof mounted.

Then I got to thinking that a 2kw generator would cost (maybe) less than the solar panel set up and put out probably close to 1500 watts, 12 amps. So, will the generator recharge my batteries (two deep cycle) in an hour where the solar would take a full day of full sun (realizing the amps used per day is unknown, just wondering about the efficiency between the two)?

When boondocking, especially when no one else is around, I don't mind running a quiet generator for an hour or two.

Solar panel specs:

Max System Voltage (IEC/UL): 600V
Voltage at Maximum Power Point: 18.0V
Maximum Power: 100 W (0%, +6%)
Current at Maximum Power Point: 5.56 A

Seems to me with the panels in full sun I could get 3-5 amps (per 100 watt panel). With the generator I'm guessing 12-15 amps (1.5-2 times what the solar would give me, assuming two 100 watt panels). Does that seem right?

Thanks.
