Burnaby, BC – July 8, 2008 - 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.
