BURNABY, Canada, May 27, 2010 - Day4 Energy Inc. (TSX: DFE), a leading
supplier of high performance, cost-effective solar electric solutions, today
announced that it has signed an agreement with Enersis, the second largest PV
company in Slovenia, for a 25 megawatt (MW) turnkey manufacturing technology
solution for the production of Day4 Energy ("Day4") branded products to
address the rapidly growing Eastern European photovoltaic market.

"We are very excited about this announcement, the first in a series of
licensing agreements that we expect will add significant revenue to Day4 from
2011 onward," said George Rubin, President of Day4. "This is a clear example
of how Day4's turnkey manufacturing technology solution provides the ability
to scale the volume of business and increase market share in emerging markets
for Day4 products and brand without a significant requirement on capital
investment by Day4."

At current market prices and full capacity utilization the 25 MW line is
expected to provide approximately 1.2 million Euros per year in royalty
revenue to Day4. Once the acquisition of ACI is complete Day4 expects to
recognize two distinct revenue streams from these transactions:

     1.  The first is one-time revenue of roughly 3 million Euros from the
         sale of equipment and consulting services related to construction
         and set up of the turnkey production line.
     2.  The second is the ongoing royalty revenue stream, as referred to
         above, on the sales of products manufactured using the turnkey
         manufacturing line.

"Eastern Europe has tremendous growth potential and is already the third
largest market on the continent behind Italy and Germany. We are looking
forward to working with Day4 in this new venture to address this unique and
exciting opportunity," added Mr. Andrej Hanzic, Director of Enersis. "Our
established relationships and position as the second largest PV industry
company in Slovenia can be leveraged for the purpose of ramping up sales of
the Day4 branded technology products."

About Day4's Manufacturing Technology Solution:


On April 26, 2010 Day4 announced that it had entered an agreement in
principle to acquire ACI-ecotec GmbH & Co. KG ("ACI"), a privately owned,
specialized photovoltaic (PV) equipment design and manufacturing company
based in Germany. The combination of the Day4 proprietary technology and
ACI's specialized know-how and equipment allows Day4 to immediately launch
the offering of its highly anticipated turn-key manufacturing technology
solution for the production of PV cells and PV modules. ACI's existing
customer relationships, execution capabilities and solid market reputation
provide Day4 with a unique opportunity to rapidly roll out its manufacturing
technology offering across a wide cross section of PV manufacturers in a
number of key markets. At the same time, ACI's manufacturing process and
equipment engineering capabilities will add significant depth to Day4's R&D
team and allow the company to significantly accelerate the development of the
next generations of PV technology.

Based on the patented Day4 Electrode and Guardian technologies, Day4's
manufacturing solution offers PV cell and module producers an opportunity to
reduce their investment and production costs while achieving sustainable
differentiation in highly competitive solar markets. The solution will allow
them to produce one of the industry's highest performing products that
customers around the world have grown to associate with the highest levels of
reliability, energy production and investment return.

With technological differentiation rapidly emerging as a critical area
for most PV manufacturers, Day4's offering of a turn-key package of
manufacturing technology, proprietary equipment, process, product design and
technology license is a natural evolution of the company's business.

By offering a turn-key Day4 PV cell and PV module manufacturing solution
to the PV industry, Day4 is looking to significantly expand the market share
of products based on Day4's proprietary technology in existing as well as new
and emerging markets around the world. Furthermore, Day4 manufacturing
solutions sales are expected to significantly alter the company's revenue
model as manufacturing line integration services and technology royalty
streams associated with the new product offering become an increasingly large
component of the company's revenue mix over time.
