Solar Power, Inc. and Solyndra, Inc. Execute Long-Term Supply Agreement for Innovative Photovoltaic Panels

Agreement Provides Solar Power, Inc. With Approximately $325
Million of Solyndra Thin-Film Panels Over Five Years
ROSEVILLE, Calif.--(Business Wire)--
Solar Power, Inc. ("SPI") (OTCBB:SOPW) has executed an amendment
to its current supply agreement with Solyndra, Inc., a Fremont,
California-based manufacturer of CIGS (Copper indium gallium selenide)
thin-film photovoltaic panels. The amended agreement, signed July 24,
2008, has a product value of approximately $325 Million for the
delivery of solar panels between 2008 - 2012 with yearly increasing
volumes and decreasing price per watt of peak output.

SPI will be one of the first companies in the U.S. to offer
Solyndra's highly innovative PV panels to its customers. The panels
feature a unique cell geometry which enables rapid installation and
high energy production for large-scale rooftops.

"We are very excited about this agreement," said Steve Kircher,
CEO of Solar Power, Inc. "Solyndra's panels are highly innovative and
offer unique design features that differentiate them from conventional
panels. Their panels and simple mounting systems are quick to install
and have outstanding energy production. The addition of their products
to our portfolio extends the range of installation opportunities we
now have; especially where available space and/or system weight are
considerations."
