I was just discussing this with someone who installed solar panels on their house about 8 months ago. I think your numbers are a little bit off. We live in south western ohio and said person took their bill from $300-400/mo to $30/mo (at 13 cents per kWh) with $11k of solar panels. They have a payoff period of about 3 years not including the $4k rebate they got which reduces the payoff cost to a little under 2 years. Keep in mind this is a place that doesn't get nearly as much sun as much more southern areas/Hawaii. I do agree that batteries still have a payoff period that is too long to be economical. Here's rooting for Mr. Musk.
