I've moved to rural Portugal (from London). I would have to get the grid extended to my place in order to get grid power, and I was quoted at around €30k. I realised that for a fraction of the price I could get a pretty beefy solar system (and – you know – free power thereafter). I went for NiFe batteries because they they are basically impossible to break. This is my first system, and I wanted to take the reliable and stress-free path. Space wasn't a concern. NiFi batteries also last circa 40 years, so the price per year is actually very cheap. However, my planning horizon is definitely not that long.
