I looked at the economics a couple of years ago. Typical break even payback was about 15 years. Panels should last 15-20 but batteries if required only last 10. So financially this a lose. In USA typical payback is 5-7 years because government rebates 30-35% of equipment and installation costs on day 1. If the government is serious about this they need to look into rebate programs.
