with 12 175 watt panels and 8 golf cart 6 volt batteries on a 24 volt system, 240v inverter,charge controller... I can LIVE in my campground, full size fridge, washer dryer, microwave, coffee pot, satellite tv lights.... It also runs my 385ft 240volt well. During the day is no problem but at night one must conserve. If I ever get off my ass and get 8 more batteries I could make it easy. Now this will NOT run AC of any kind long enough to make a difference., heat is no problem though.
Coffee and Microwave use A LOT of power, way more than any other appliance.,
My campsite is on the lee side of a hill, surrounded by many trees and up in the mountains. On a typical summer day, I get a few hours of direct sunlight, but in the middle of winter not much at all. Even if I could afford the price of 12 panels and the batteries required, I do not have the space available to properly install and maintain them.
Plus with the constant drain of cooling (A/C) in the height of summer, and heating in the middle of winter especially when it snows for days on end here, I do not think I will be able to totally separate from the mains supply for most needs, unfortunately.
Then add in the equipment needed for a two-way link to connect with the internet by radio, and having to rely on a laptop only for its limited energy requirements, and you soon will come to the same conclusion I did: that it is not yet ready for primetime.
