Rain catching wasn't really an option here in AZ like it would be in Kentucky. and yeah, I hear ya about the AC. Summers here were in the 110 plus for weeks on end. Two of our neighbors died from heat stroke my wife suffered from heat stress too. But we came through. To live off grid is good, unless you have to pump water from 700+ ft down straight up to the surface, then you'll need a little more than 2000 watts. Also something people don't believe when I tell them is count up and add ALL your watt usage, with the phantom watts included, and times it by 5. That is what size power watt source you need. Then you can start illuminating the stupid use, huh.
We took and still take military type showers. Wet down, soap up and rinse, get out. No standing there for a half hr singing away. I learned while hauling, water is PRECIOUS and keep my 2500 gal holding tank full. Let it go empty and that's when, (by Murphy's law) the truck breaks down or the well pump takes a dump.
Another thing when you go to build, the bigger the McMansion, the more to heat and cool. We have about a 700 sq ft single wide mobile and for two, it's MORE than enough. People these days want bigger and better but it's too costly for living out.
We had, for the longest time, no cell and Internet service. Then hughes satelite came, (it sucks), and now within the last week we got 3 bars of 4G out here. Now hughes is going bye-bye and were going MiFi from the phone comp.
your set up looks great and sounds great.
