A Solar Panel on Every Roof?
In U.S., Still a Distant Dream
Daunted by high up-front costs, U.S. homeowners continue to shy away from residential solar power systems, even as utility-scale solar projects are taking off. But with do-it-yourself kits and other innovative installation approaches now on the market, residential solar is having modest growth.

It seems like the ultimate in green technology for an emissions-savvy citizen of the 21st century: solar panels on your roof, providing carbon dioxide-free electricity whenever the sun is shining. But as huge utility-scale solar and wind projects continue to make news and the economy continues to struggle, the state of the residential solar sector in the United States remains decidedly mixed.
From the first quarter of 2010 to the fourth quarter, installations of U.S. residential solar systems rose from 62 megawatts to 74 megawatts (enough to power about 15,000 homes), and the Solar Energy Industries Association reports that

Considering that the total installed solar capacity in the U.S. — residential, commercial, and industrial-scale of all types included — still hasn’t cracked 3,000 megawatts (enough to power roughly 600,000 homes), this feels like progress.
Yet if you look at residential solar’s share of the total U.S. solar market, the picture is less bright. In 2009, 36 percent of all installed solar systems were on homes;

“The way the U.S. solar market is really headed is toward utility projects,” said MJ Shiao, a solar markets analyst with
