I 2nd that! Bob says he does NOT need any generator at all - but obviously does a lot of "adjusting" to the situation.
He only runs 2 panels and gets by....
If you have the space you can do a Solar-FARM up there and a battery BANK underneath!
However you need to take the time to really read the whole website - details everywhere!!
Especially details about charging voltage, wire size and shadows (even the smallest ones!) on the panels are important!
Where I do not agree (...and I guess others neither) is his insistence on liquid lead-acid batteries vs. the newer no-maintenance types...
[...you'll find it]
