SAN JOSE, Calif., Oct 20, 2008 /PRNewswire-FirstCall via COMTEX News Network/ -- SunPower Corporation (Nasdaq: SPWRA, SPWRB), a Silicon Valley-based manufacturer of high-efficiency solar cells, solar panels and solar systems, today announced that utilities veteran Dennis V. Arriola has been named SunPower's senior vice president and chief financial officer (CFO).

Arriola will join SunPower in November, reporting to CEO Tom Werner. In this strategic role, Arriola will lead the company's global finance, planning and accounting organizations, as SunPower continues its growth in the residential, commercial and utility solar markets.

"Dennis brings to SunPower a wealth of experience in the power markets and the natural gas markets both in the U.S. and abroad," said Tom Werner, SunPower's CEO. "SunPower is leading the solar PV sector into the utility- scale business. We believe a CFO who deeply understands both regulated and restructured energy markets will accelerate our growth in that sector."

With more than 20 years of financial experience, Arriola was most recently senior vice president and CFO at San Diego Gas & Electric and Southern California Gas Co., Sempra Energy's California regulated utilities. In this role, he was instrumental in building the finance and treasury teams, which included accounting, planning and budgeting, strategic development, risk management, information technology, and procurement. He was a key member of the Risk Management Committee, where he reviewed major energy commodity contracts and policy direction.

"The power industry is in the process of transforming to address fuel price volatility, supply reliability and climate change," said Dennis Arriola, incoming CFO for SunPower. "Solar PV power is an attractive retail and wholesale peaking power resource because it can be sited anywhere, at any scale and is fast to market. SunPower has a leading position in the industry and I look forward to working with its world-class team to build strong growth for shareholders, superior products and services for customers, and a great company for employees."

During his 14 year tenure at Sempra Energy, Arriola also served as vice president of communications and investor relations. From 1998 to 2001, he was the company's regional president and general manager, South American Operations, where he managed the company's investments in Argentina, Chile and Peru. From 1994 to 1998, he was vice president and treasurer for Pacific Enterprises/Southern California Gas Company where he oversaw the treasury and finance operations, including cash management, capital markets activity, foreign exchange, leasing, dividend policy and relationships with various commercial and investment banks.

Arriola earned a master's degree in business administration from Harvard University and a bachelor's degree in economics from Stanford University. He also serves as a trustee for the Tomas Rivera Policy Institute in Los Angeles, and as a member of the board of directors of the San Diego Symphony. He was recently named one of the top 100 most influential Hispanics by HispanicBusiness.com.

Arriola will work closely with retiring CFO, Manny Hernandez, through January 2009. Hernandez, who joined SunPower in 2005, was instrumental in orchestrating SunPower's successful initial public offering in November of 2005 and has continued to guide the company's growing revenue, estimated to be more than $1.4 billion in 2008.
