California-based Sunrun and Harris Interactive recently announced the results of a survey of 2,211 adults (1,475 homeowners) about the cost and desirability of installing a home solar system. The main sound bite is the one-liner that “97% of Americans overestimate the cost of going solar,” as well as the stat that “nearly 8 out of 10 of those who do not already have solar panels say they would install solar if cost were not a factor.”
One Block Off the Grid took a stab at answering the question: “How big a backyard do you need to live off of the land?“ It turns out, plants like corn, wheat, fruits, grains, and vegetables take a lot of space. Also, to offset the electricity required to power the average home in the U.S., which consumes about 11,040 kWh per year, one needs about 375 square feet of solar PV, or 25 average efficiency solar panels getting seven hours of sun.

Research suggests that homeowners with solar PV will recoup the cost of their solar investment upon sale of the home. Homes with PV systems sell for a premium over comparable homes without PV systems, according to a study of home sales in California from 2000-2009 by the Lawrence Berkeley National Laboratory.
