Day4 Energy's First solarSYSTEMS Franchise Partner is Fully Operational

BURNABY, Canada, October 25, 2010 - Day4 Energy Inc. (TSX: DFE), a leading global provider of solar
photovoltaic (pv) products and solutions, announces that one of the first
franchise partners to join Day4 solarSYSTEMS turnkey manufacturing program,
Gebäude-Solarsysteme GmbH (GSS) of Thuringia, Germany, is fully operational
and delivering Day4 branded solar pv modules for custom applications - ahead
of schedule. This announcement comes several months ahead of the anticipated
production launch schedule. When operating at maximum capacity, the line is
expected to produce 15MW annually and generate significant royalty revenue
for Day4 Energy.

As the oldest and most respected PV company in Germany, GSS is the first
solarSYSTEM partner to begin the manufacture and distribution of Day4's
advanced solar modules for its roof-integrated PV solutions and other
building integrated PV (BIPV) products based on high efficiency,
monocrystalline solar cells. With strong market presence in France and
Belgium, the addition of the Day4 solar technology and manufacturing
processes extends the reach of Day4 branded products into a new vertical
market. And as solar approaches grid parity in many markets, combining PV
technologies with construction materials is becoming increasingly important
with the rapidly growing BIPV market.

"The roof-integrated market in France is becoming a significant market
within central Europe," says George Rubin, President of Day4. "Incorporating
Day4 technology into new products for GSS clients, including roofing
materials for construction and automotive applications, allows Day4 to
leverage the longstanding relationships GSS established over the years in
these market segments."

"We are very pleased to be Day4 Energy's first manufacturing partner.
After a successful installation in August, we are in the process of ramping
up and applying our strengths in customization, certification and
manufacturing to developing new products based upon Day4 Energy's advanced pv
technology" said Mr. Höhne, Director of GSS.

Day4 solarSYSTEMS is an innovative franchise partnership program from
Day4 Energy that enables businesses to manufacture, distribute and sell
certified DAY4 branded solar modules and expand our advanced technology to
markets across the globe. As a revolutionary approach and the first in the
industry, this turnkey manufacturing package allows partners to swiftly
establish a production facility and generate revenue growth.

The North American introduction of Day4 Energy's solarSYSTEMS recently
occurred at Solar Power International held in Los Angeles, California. To
