Solar roof cheaper than a normal roof
Is it possible that solar roof would be cheaper than a normal roof? According to Elon Musk it is.
"It's looking quite promising that a solar roof will actually cost less than a normal roof before you even take the value of electricity into account. So the basic proposition would be, 'Would you like a roof that looks better than a normal roof, lasts twice as long, costs less, and by the way generates electricity?' It's like, why would you get anything else?"
