BURNABY, Canada, July 13, 2010 - Day4 Energy Inc. (TSX: DFE), a leading
global provider of solar photovoltaic products and solutions, today announced
it has completed the construction of two turnkey, ground-mounted photovoltaic
power plants in Germany totaling over 2.5MW.

Built for a repeat customer of Day4 Energy, the 1.8MW Solarfarm
Fischbach project in Niedereschach-Fischbach consists of 9,792 Day4 Energy 48
MC-S panels. Designed to produce enough power for over 500 households, this
project will contribute to the reduction of approximately 1,170 tons of
carbon-dioxide annually.

The second project recently competed was a 715kW installation built for
Kreissparkasse Rottweil, a local savings bank in Germany. Comprising 3,920
Day4 Energy 48MC-S panels, the Energiepark Zimmern will produce enough
electrical power for 200 households and will yield an annual reduction of
approximately 464 tons of carbon-dioxide.

"The successful completion of these two projects, in particular the fact
that it took just six weeks from construction commencement to grid
connection, confirms Day4 Energy's outstanding project management expertise,"
noted George Rubin, President of Day4 Energy. "As we continue to develop and
promote both our project management and turn-key manufacturing capabilities,
Day4 Energy is establishing itself as a strong partner, and catalyst for the
widespread adoption of solar photovoltaics in markets across the world,"
concluded Mr. Rubin.

Day4 Energy continues to grow its presence in the solar project market,
and intends to scale its project development business model to markets
outside of Germany, most notably Italy and Canada, in the coming year.
