[The only reason I could justify investment in some kind of “off grid” alternative is if I was sincerely concerned that the “grid” was going away.]
Or ... if you really wanted to live a little further off the beaten path. Get a mile away from existing power lines and see how much the utility company wants to charge you to run power to your property.
As solar PV systems come down in price, it will allow people to spread out more without waiting for the grid to expand. For people like me that don’t want to live in tract housing, cheaper PV is key.
My wife and I travel to Yellowstone National Park on a regular basis from April until October. In that journey, we pass through an area called Island Park. There are some very nice areas along the road with custom built log cabins dotting the hillside. That would be a great place for a retirement or vacation home. There is just enough connectivity (1xRTT) to permit me to work if I wanted to do so. Living in that area would require real discipline in shopping runs...even for basic necessities. It's just a little too far off the beaten path for the requirements of my current employment.
