I am not sure there are a lot of folks who will spend 70k on a roof. Even if it reduces or eliminates their electricity costs.
For this to succeed it is going to have to cost the home owner at least what a shingled roof would cost with the additional cost of the power-wall and the infrastructure that is required to to set that up. I can understand paying a slight premium but 70k?
You would be better off using a high performance insulation like spray foam, 3 pane windows, and even installing a Geo Thermal System (around 20-25k) instead of this solar roof.
