SAN JOSE, Calif., June 4 /PRNewswire-FirstCall/ – SunPower Corp.

“This is an exciting and auspicious time for the solar industry and for SunPower. We are bringing truly attainable solar power to homes and businesses everywhere, at a time when it is most critical,” said Jan Soderstrom, chief marketing officer of SunPower. “Our new digital platform and ad campaign are important steps towards providing people with the knowledge and tools to control the rising cost of energy and achieve significant rates of return on their solar investment.”

The “SeizeToday” campaign, created by Tribal DDB in partnership with DDB San Francisco, is reaching homeowners and businesses with radio and digital advertising. Additionally, the campaign uses outdoor, transit and airport advertising, with headlines like “re-volt,” “use more sun,” “a guaranteed return with every sunrise,” and “rooftop stimulus packages now available.” A micro-site, www.seizetoday.com, is also used to enable customers to learn more.

To take advantage of its leadership position in the solar industry, SunPower has also refreshed its website, www.sunpowercorp.com, to focus on actual customers and their success stories and savings, thanks to their SunPower systems.

Top benefits and offerings on the new digital platform, also created by Tribal DDB, include:

• Online estimator tool, with integrated Google Maps, that allows consumers to estimate the price of the installation of the system (factoring in federal, state and local tax credits) and ongoing savings specific to their home
• Content and testimonials that show the time for solar is now
• Link to an application for the Apple iPhone(TM) or the iPod touch mobile devices to monitor system power generation
• An informative and consumer-focused blog feature

“We are honored to be SunPower’s partner in leading the solar revolution,” said Geoff Gougion, managing director of Tribal DDB San Francisco. “SunPower is a recognized global leader in the solar industry, and we are thrilled to be taking their brand to market using mass media and smart, digital platforms.”
