msw--you might check the link from LakeTimes on cost--showing a Tesla roof at $2.01/watt (and that includes the roof itself!). If accurate, that would be shockingly low--I paid over $3/watt, just for standard (high end) solar.
Agreed that a standard solar roof is more proven--there are millions of them working trouble-free.
I look forward to LakeTimes's report on actual price quotes
