Solar is wonderful if you set it up right and camp in sunny locations. I'd want to know more before I'd pin it down to 130w.
A generator is a simpler answer but a pain to deal with and listen to. A larger one can run the air and it doesn't care if it's cloudy.
For us it is both. Enough solar to let us do anything but run the air and a cheap generator we never need but it's nice it is there if we ever do. This may be "Sunny Colorado" but the monsoon can bring a week of clouds. We don't plan on conserving or going home early, so a back up is good to have.
