The 2.5 kilowatt rooftop solar system is comprised of the SunPower E18 Series solar panels that produce an average of 3,000 kilowatt hours of electricity annually. These high-efficiency solar panels generate approximately 50 percent more electricity than conventional panels and utilize a smaller footprint on the roof. The system was sized to accommodate a customer who drives about 1,000 miles per month.
Included in the purchase is a residential monitoring system, which includes the ability to track the performance of their solar system on the web or through an iPhone application. In addition to the Focus Electric, the SunPower rooftop solar system will be compatible with the C-MAX Energi plug-in hybrid electric vehicle Ford is rolling out in 2012.
