2x 140w 12v panel & parallel connectors $288Morningstar 20 amp controller $77100' (50' effective) #10 wire with MC4 connectors $71That is ~$450 for a nice set up. Put the panels together with a hinge on one side and some handles on the other to make portable. You can call and order the wire as long as you think you need. Although the solar wire is a bit stiff so you may prefer some duplex #10 for a portable system.
#10 duplex $1.05 per foot shippedWhether you go solar or generator you still need a second battery.
With a generator you may still need to spend an additional $100 to $200 to upgrade the charging system unless you happen to already have a 25 to 40 amp portable charger.
Also generator or solar you may want an inverter to run/charge the 120vac stuff.
I have not carried a generator since adding solar. Although my system is a bit bigger it is very possible and I think you will do great with the above system.
