Does going solar pay off?
Excerpt:
"Even as states ramp up incentives, the payback for homeowners remains elusive....
Despite the minuscule amount of solar power generated today -- roughly one-thirtieth of 1% of all the electricity produced in the U.S. -- recent technological advances and a continued decline in the price of solar systems are prompting more homeowners to ask if this renewable energy source is now worth the investment.
Analysts say they are still crunching the numbers when it comes to deciding whether residential solar systems, also referred to as photovoltaic or PV systems, make economic sense. The answer hinges on how much and how fast solar can cut a homeowner's utility bills and thus how long it takes to pay off the initial investment to add solar panels to a home."
