SPI Solar Awarded a 1.69 Megawatt Solar Energy Facility Project in New Jersey

Roseville, CA, June 20, 2011— SPI Solar (“SPI”) (OTCBB: SOPW) a leading
developer of photovoltaic (“PV”) solar energy facilities (“SEF”), today announced
that it has entered into an engineering, procurement and construction (“EPC”)
contract to serve as EPC contractor for a 1.69MW DC photovoltaic solar project
in New Jersey. The system will be a roof-mounted distributed generation system
for on-site power consumption. The project will be owned and operated by
NuGen Capital Management, LLC (“NuGen”), through a NuGen wholly owned
subsidiary.
The SEF being built by SPI will be connected to 5 independent meters serving
tenants at the complex owned by North Jersey Development Group, Inc. Most
recently, SPI worked with NuGen on the 5-megawatt White Rose Foods project
currently under construction in New Jersey. “We are very happy to have been
selected once again by NuGen for this project,” said Steve Kircher, CEO of SPI.
“The project fits nicely within our strategy to further establish our presence in the
northeastern US.”
NuGen works with large-scale energy users and real estate owners to develop,
own, and operate commercial-scale PV solar systems. “I am pleased to be
working with SPI once again on this project, and look forward to others in the
future as NuGen seeks to invest capital in additional opportunities throughout the
Northeast,” said David Milner, CEO for NuGen. “SPI’s experience base and track
record in the solar industry make a big difference when it comes to selecting a
partner for projects such as these,” Mr. Milner concluded. The 1.69 MW project
was co-developed by NuGen and Solaire Development, LLC (“Solaire”) through a
joint development agreement between the two companies. NuGen and Solaire
are currently in the process of collaborating on additional projects.

Construction on the project is scheduled to begin in July 2011.
