If you’ve assumed Tesla Solar roofs would be priced sky high, prepare to be amazed.
The company opened up ordering last week and they priced, on average, at $21.85 per square foot. That’s less than the cost of a regular roof, taking into consideration the energy savings over a 30-year period.
These roofs aren’t 100 percent solar tiles — they’re a mix of non-active tiles and active solar tiles, depending on the energy needs of a house. Non-active tiles cost $11 per square foot; active solar tiles cost $42 per square foot. So for a house needing 35 percent solar panels, the cost works out to $21.85 per square foot. There are lots of variables in determining the percentage of active tiles, of course, like the location of the home and shape and height of the roof.
To put this in perspective, Consumer Reports estimated that a solar roof needs to be $24.50 per square foot to be competitive with other kinds of roofing materials.
