OP is from Ma, and dry camps a lot, if you are going to Maine, Northern NH, or even into Ca, you are likely in very wooded areas. Just remember that when the panels are shaded, even partially, their production goes way down. They are great though in that your batteries can top off if you have the sun available all day, the Genny will boost you up in the morning, but after getting you back to maybe 75% slows way down on charging and becomes very un-economical for charging. The best of both worlds appears to be to fire up the genny for a while in the morning for getting most of the charge back, making coffee, morning news for some and then letting the solar do what its best at, long slow charge to top off.
