SAN JOSE, Calif., Oct. 19, 2012 /PRNewswire/ -- In a dedication ceremony today
attended by Acting Assistant Secretary of the Navy Roger Natsuhara,  SunPower
Corp. (NASDAQ: SPWR) announced the completion of the largest solar system in
the US Navy, a 13.78-megawatt (DC) solar photovoltaic (PV) power system at
Naval Air Weapons Station China Lake (NAWS China Lake) in Calif. Using
SunPower's high-efficiency, Buy American-compliant solar panels, the plant is
generating the equivalent of more than 30 percent of China Lake's annual
energy load, helping to reduce costs by an estimated $13 million over the next
20 years.

Using a long-term energy procurement authority (US Code Section 2922A), the
power plant is the first federal agency project to be financed through a
20-year term solar power purchase agreement (PPA). The 20-year PPA requires no
upfront capital or maintenance obligations from the Navy, matches conventional
project financing terms for solar power facilities, and allows the Navy to
secure electricity at up to 30 percent below the rate available through
shorter duration 10-year PPAs.

"SunPower congratulates the Navy for its forward-thinking commitment to solar
as a reliable resource that strengthens this country's energy independence and
security. This 20-year PPA will significantly lower long-term electricity
costs at China Lake, and can be used as a template for additional large-scale
federal solar projects," said Howard Wenger, president, regions, of SunPower.
"With 52 megawatts installed, SunPower has more than a decade of experience
working with the federal government.We are pleased to be the leading solar
provider to the U.S. government, delivering cost-effective solar solutions
that generate the highest value returns over the long term."

An affiliate of MetLife, Inc. purchased the system that SunPower designed,
built and is operating and maintaining. NAWS China Lake is hosting the system,
and buying electricity at prices currently below the retail utility rate,
which provides the Navy with a long-term hedge against rising power prices and
required no initial capital investment.

At the China Lake site, SunPower installed its SunPower Oasis™ Power Plant
product, a fully integrated, modular solar power block that is engineered to
rapidly and cost-effectively deploy utility-scale solar projects while
optimizing land use. Each power block integrates the SunPower® T0 Tracker with
SunPower's high-efficiency solar panels, pre-manufactured system cabling, the
Oasis smart inverter and the Oasis operating system.

SunPower has installed more than 50 megawatts of solar power systems at
government facilities to date. The systems the company has delivered to the
U.S. Navy and U.S. Air Force alone generate the equivalent amount of
electricity for about 9,000 homes. According to U.S. Environmental Protection
Agency estimates, the Navy and Air Force systems will reduce the amount of
carbon dioxide emitted into the atmosphere by almost 732,000 tons over the
next 20 years, which is equal to avoiding the emissions from burning 1.5
million barrels of oil.
