Day4 Energy Announces First 1MW Solar Installation in Pisa, Italy

Project Signifies Day4 Energy's Growing Market Acceptance in the Increasingly Important Italian Market for Advanced Solar Modules

BURNABY, British Columbia, November 17, 2010 - Day4 Energy Inc. (TSX: DFE), a leading global provider of solar
photovoltaic (PV) products and solutions, announces an agreement with Orciano
Ambiente Srl., a leading Italian solar project developer, to provide its
60-MCI Day4 solarMODULES for the first 1MW ground-mounted solar photovoltaic
system to be installed in the town of Orciano Pisano, Italy.

Euro Sistem Srl., a leading Engineering, Procurement and Construction
(EPC) firm for PV systems, is scheduled to complete the 1MW solar project by
December 2010. The project is expected to be fully commissioned and
operational by February 2011.

"As a leading European market for solar PV installations, Italy is
projected to add roughly 1,000 megawatts of capacity each year over the next
three years." says Riccardo Felicioli, Senior Project Consultant. "And Day4's
participation in large-scale projects such as this one confirms the continued
acceptance of their advanced solar modules in a rapidly growing market."

The announcement also marks Day4 solarMODULES achieving bankability
status in the Italian market from the project's lending institution,
Unicredit Leasing ("Unicredit"), one of the most reputable and active
institutions for the leasing and project financing of large-scale solar
installations in Italy. Unicredit was awarded "Italian Lessor of the Year
2010" at the Leasing Life Asset Finance Awards on November 10, 2010.

"Achieving bankability from one of Italy's most respected financial
institutions solidifies Day4's position as a valued provider of advanced
solar technology and emphasizes the high quality, durability and superior
performance of our solarMODULES for large-scale projects throughout Europe."
says Luigi Fusi, Director of Sales and Corporate Development for Southern
Europe.

"This project clearly demonstrates our efforts and progress to becoming a
primary provider of solar solutions for the Italian market, and will be of
significant benefit to our solarSYSTEMS manufacturing partners" concludes Mr.
George Rubin, President of Day4 Energy.

Bankability is a term used by financial institutions as to whether the
technology and products are seen as acceptable, dependable and reliable in
terms of the overall investment by the lending group. When determining
bankability for solar energy project funding, financiers seek the lowest risk
on the many variables present, which include product quality, completion
likelihood, off-taker (power purchaser) credit worthiness, project model
quality, and environmental factors.
