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?

"So that, again, adds another two years to our payback period." So you're up to 17 years now. "We're up to 17 years, which is, essentially, the life of the system. And we haven't even considered what happens if the system breaks or what it's gonna to cost to take the system off the roof and dispose of it." Despite this, Scott says she's still happy to have the panels on her house. "But now, knowing that it's maybe, at best, a break-even proposition, we're not so comfortable telling other people to do it." Scott's experience raises questions about the viability of much larger, utility-scale solar projects built in recent years. Richard Caperton is director of clean energy investment at the Center for American Progress. He says that's not a concern. Many were built with contracts that have set prices. "What's more interesting, though, is that the plants that aren't getting built right now, because of cheap natural gas." Caperton says solar, wind and even nuclear seem less attractive for investors right now, but that can change quickly. In the past, natural gas prices, like the stock market, have shot up quickly. If that happens, solar panels will seem like a good investment once again.
