SPI Solar to Serve as Developer of a 4.4 Megawatt Utility- Scale Solar Energy Facility in Greece

Roseville, CA, August 15, 2011—SPI Solar (“SPI”) (OTCBB: SOPW) a leading
vertically integrated photovoltaic (“PV”) solar developer and engineering, procurement
and construction (“EPC”) services provider, announced today that it has successfully
completed the acquisition of the necessary contracts and permits to serve as developer
of a 4.4 megawatt fixed-ground-mount solar energy facility (SEF) which will be located
in Evros, a North Eastern region of Greece. SPI became the developer of record for the
project by acquiring a 100% limited partnership interest in the project, which was
already in early-phase planning with another entity. The SEF will be a fixed-tilt ground-
mount utility-scale facility (on approximately 25 acres) selling power to the Greek Public
Power Corporation (“PPC”) through a 20-year Power Purchase Agreement (PPA).
Prior to executing the agreements, SPI worked with Global Energy Services (“GES”) to
identify the build-ready project, and with SDL Solar to perform on-site technical due
diligence and qualify the project for development. GES will work closely with SPI to also
provide project oversight during the construction of the SEF. Additionally, SPI intends
to perform operations and maintenance of the completed facility over the term of the
PPA. SPI’s proprietary monitoring application, Solar PowerViewTM will be used to
monitor the system and ensure optimal system performance and energy production.
The SEF will use LDK’s high-performance solar modules.
The SEF will be located in Evros, in Northeastern Greece, approximately 100 miles
north of Alexandropoulos and just six miles from the Turkish border. Construction is
scheduled to begin in November 2011. Consistent with SPI’s business plan as a SEF
developer, it is the Company’s intention to sell the project during the construction phase
or upon commissioning.
“This is our first project in Greece and we are excited about initiating what we believe
will be the first of several projects there,” said Stephen Kircher, CEO of SPI. “The
system design-build requirements for this project are a perfect match to our skill set and
experience. We will also be creating jobs over the course of this project’s development
which is a plus for the Greek economy,” Mr. Kircher pointed out. “We look forward to
the successful execution of this project and to more projects in Greece and selectively
throughout Europe,” Mr. Kircher concluded.
