In the spring of 2017, Tesla announced pricing for their new solar roof product (the Tesla Solar Roof), a roof replacement for your home. And as of January 2019, Tesla is producing the solar roof at their Buffalo Gigafactory, albeit slowly. Installations have begun for the top of their waitlist though mass-market availability still remains unclear.

We’d just closed on the house in Southern Vermont. Fortunately, the sellers left the house mostly furnished and stocked with supplies and a helpful “home instructions” booklet. One line of their “home instructions” stood out to us: “In the event of a power outage, there are flashlights and candles in the mudroom.”
