概括:Classic supply and demand is a good thing for most of people who didn't invest in solar panels. But will natural gas still remain a bargain compete with solar panels several years later?

For utilities that burn natural gas to produce electricity, this has allowed them to hold the line on rates. For most of us, that's a good thing. But for Barbara Scott of Media, Pennsylvania, it's made her solar system less of a bargain. "We've got seven panels on the roof – on the porch roof - and 14 on the main part of the house." Scott says her family was the first in the community to install solar panels last march and she was prepared to be an evangelist. "We said, look, we've got our website where you can see our panels at work. And we can have open houses and write newsletter articles and promote the idea of solar." After rebates and tax incentives, Scott says her family spent $21,000 to install the system. She figured it would take eight years to recoup the investment. A lot of other people had the same idea at the same time, which sent the price of solar energy credits down. That added seven years to the payback period. On top of that, Scott says electricity rates aren't going up as quickly as she thought they would, thanks, in part, to low natural gas prices.
