On Friday evening Tesla officially announced an integrated solar roof and Powerwall product for individual use. When or if the roof and the Powerwall become available to consumers is most likely contingent on Tesla and SolarCity investors voting to approve Tesla’s offer to buy SolarCity in a $2.6 billion (£2.1 billion) all-stock deal on November 17.
Estimated costs for the unit are, to quote Musk, “it’s not gonna make sense for somebody to replace a brand new roof with a solar roof. But if your roof needs replacing anyway the cost/benefit could make sense”. So if speccing out a new house, it looks like it could be a fairly sensible option.
