We are off grid, just purchased solar + batteries that will supply all power needs, including running aircon and hot water at night. That's the purchase price, amortised over 10 years assuming our current daily usage.
The reality is our anticipated power usage will go up with electric cars and the system is speced to cope, and parts will last over twice the 10 years.
I suspect your question was purely retorical. You weren't fishing for an answer is effectively "cheaper than I can buy electricity from the local coal fired utility", but that is the reality. Nuclear costs about twice that.
Notice I'm paying retail. If you are going to compare wholesale prices to the $0.20 you typically have to multiply them by 3.
