Interesting stuff, Z.
Dow reports that a typical residential cluster of 350 solar singles on a roof could slash one’s household electric bill by 40-60 percent. Such an installation can cost a homeowner over $20,000, but federal, state and local incentives can bring the cost to half that in some areas. Powerhouse shingles are currently available (from Dow-authorized contractors) in California, Colorado, Connecticut, Louisiana, Maryland, Massachusetts, Michigan, New York, North Carolina, Texas and Washington, D.C.

If the "incentives" bring that down to ten grand, that starts to sound like a pretty good alternative to re-roofing with plain asphalt shingles.
That makes me think that someday a roof covered in asphalt shingles will be obsolete.
