we were camping for 10 days with only about 5 hours of sun each day in early september. we ran microwave each day for maybe 10 minutes, ran LED lights at night, CPAP, furnace for 2-3 hours each day, TV occasionally. with 350 watts of solar we never needed to run the generator. batteries were down to about 80 percent charge after 10 days.
So nice to have it quite all the time, and enjoy the outdoors.
today you can get 320 watts of portable solar for $320. For a fixed system 500 watts of solar panels will cost only about $400. Add $100 for a controller.
In fact, the last time I needed to run the generator while camping was over 2 years ago to run the AC for a while.
