KB Home has become the first home builder to offer SunPower’s new OneRoof product at its Ashbury new-home community in the San Francisco Bay Area.

In 2011, KB Home partnered with SunPower to introduce the home builder’s first all-solar community.

During the past 18 months, SunPower’s Research and Development team collaborated with KB Home to develop SunPower OneRoof.

The new product features interlocking metal roof trays with integrated panel clips to install SunPower solar panels directly to the roof deck.

“KB Home has once again demonstrated its leadership, and given our long-time partnership with the home builder, we are confident that OneRoof will be another successful collaboration. OneRoof is an innovative solution for home builders working to meet California’s new-home solar mandate, as well as for other states that are considering similar policies. Given our place in the new-home market, investing in the development of a complete integrated solar system to benefit home builders was a priority, and we plan to incorporate OneRoof into all new-home installations.”

Tom Werner, SunPower CEO and chairman of the board.

“We are proud to have paved the way by providing energy savings potential to thousands of our homeowners through renewable solar power, which helps to lower their overall cost of home ownership and enables them to enjoy a more sustainable lifestyle. Early on, we recognized that, through innovation and partnership with SunPower, we could create a winning solar combination for our homeowners.”

Jeff Mezger, chairman, president and chief executive officer of KB Home.
