SunPower claims that its panels will form the cornerstone of Toshiba’s new residential solar offering in Japan, to be launched in April this year.

Tom Werner, CEO of SunPower, said: “We welcome the opportunity to partner with Toshiba, a preeminent business leader in Japan and throughout the world. SunPower panels are particularly well suited to Japan’s residential market, where the new Japanese feed-in-tariff rewards production of solar energy in excess of domestic consumption, but available roof area is typically quite small. SunPower high efficiency systems will allow more customers to take advantage of this incentive.”

SunPower almost doubled production of its solar cells and panels from 2008 to 2009, with 2009 cell production of approximately 400MW. In 2010, the company intends to expand production further with new manufacturing operations in Malaysia, the US and Europe, the company said.
