When the cost of such an array is around US$4,000 (compared to US$30,000 now), home builders and companies that refurbish homes will put them up on a large scale in no time flat, because being able to not be so dependent on the electric grid makes a lot of economic sense. And that US$4,000 array is very close to reality with new, low-cost solar panels made with nanotechnology in thin sheets.
