Day4 Energy Granted U.S., India, Mexico Patent Approval for Proprietary Photovoltaic Technology

    Patented Day4 Electrode Improves Solar Module Power Output, Lifetime,

    BURNABY, British Columbia, July 8 /CNW/ -- Day4 Energy Inc. (TSX: DFE), a
leading manufacturer of high performance, cost-effective solar electric
modules, announced the successful completion of the patent application process
for one of the key elements of its intellectual property, the Day4 Electrode,
in the United States, India and Mexico. The newly awarded patents add to
existing patent protection held for the Day4 Electrode in other important
regions including the European Union.
    "The Day4 Electrode is central to our IP portfolio.  In less than two
years since original market launch this technology has already proven its
ability to take product performance far beyond that of conventional
decades-old PV module soldering technology. Even so, we have only tapped the
surface of the full potential offered by our enabling electrode technology
that is poised to re-define not only the PV module but the ways the industry
designs and manufactures PV cells themselves," said Professor Leonid Rubin,
chief technology officer of Day4 Energy.
    Added George Rubin, president of Day4 Energy, "We are currently in a
high-growth mode at Day4 Energy driven largely by international demand for our
advanced solar electric modules. These patent allowances provide critical IP
protection as we rapidly expand our customer and partner relationships in
North America, Europe and Asia."
    The Day4 Electrode is an advanced solar module technology that directly
replaces the conventional soldering methods that are widely used throughout
today's solar industry. By improving connections to and between photovoltaic
(PV) cells, the Day4 Electrode delivers quality solar electric products with
higher performance, longer lifetime, improved aesthetics and lower cost. The
Day4 Electrode further enables design and commercial production of next
generation PV cell technologies that are not compatible with the conventional
solder based approach to PV module manufacturing. Day4 Energy is seeking
patent protection for this and other related technologies in a number of
additional countries worldwide.

    About Day4 Energy:
    Headquartered near Vancouver, British Columbia, Day4 Energy Inc. (TSX:
DFE) designs, manufactures and sells photovoltaic (PV) modules based on its
patented Day4 Electrode technology, a proprietary method of contacting and
interconnecting solar cells that produces PV panels of high power density,
increased lifetime and uncompromised aesthetic appearance. Day4 Energy
partners with the industry's leading PV cell producers to deliver IEC- and UL-
certified commercial and residential solar products to customers throughout
Europe and North America.
