Understanding Future Uses of Roofspace and Defining An Early Path to Profitable Roof Estate Investing
March 25th, 2011
Via The New York Times, an interesting article on the economics of solar panels improving enough to become standard features on entry level homes in California:
Among the standard features offered for new homes at Manzanita at Paseo del Sol, a KB Home development in a desert suburb southeast of Los Angeles, are nine-foot ceilings, six-panel doors and a 1.4-kilowatt solar array.
While KB Home has offered rooftop photovoltaic panels as an option for some time, the home builder now will make solar arrays from SunPower standard equipment on more than 800 homes in 10 communities being built in Southern California.
“This is a game changer for our industry and a powerful way for us to compete in the marketplace, especially with resale homes,” Craig LeMessurier, KB Home’s director of corporate communications, said in an e-mail. While pricey solar panels are often found on the roofs of high-end houses, it’s notable that KB Home is installing the arrays on homes with base selling prices that range from $250,000 to $360,000. In California, that’s starter home territory.
KB Home estimates that the standard 1.4-kilowatt solar array will supply about 30 percent of the electricity for an 1,800-foot to 2,000-foot square home. Of course, that all depends on how much a homeowner runs their air conditioning, for instance.
Rooftop solar can be a hedge against California’s high and rising electricity rates. And given the intense sunshine and air-conditioning demands in desert areas where KB Home is building its latest developments, such arrays will generate more electricity than they could in, say, San Francisco. Homeowners will also qualify for a 30 percent federal tax credit as well as state incentives.
For those who want to offset more of their electricity use, KB Home is offering an optional 3.2-kilowatt, 14-panel array. (Which would come in handy if you buy an electric car.) Under California’s net metering law, homeowners and businesses can zero-out their electricity bills by feeding enough solar-generated electricity into the grid to offset their power consumption.
“Our Energy Star-qualified homes are already among the most energy-efficient available today,” Mr. LeMessurier said, referring to the federal program to rate energy efficient buildings and appliances. “This raises the bar even higher, and makes our homes even more affordable.”
