XsunX Build-Out of Marketing and Technology Development Facility on Track

Assembly of Core Production Systems to Begin on Site in July

ALISO VIEJO, Calif., June 13, 2006 — XsunX, Inc. (OTCBB: XSNX), provider of technologies for solar energy infrastructure and developer of Power Glass™, an innovative thin-film solar technology that is intended to allow glass windows to produce electricity from the power of the sun, today announced that improvements to the Company’s new Golden, Colo. facility are on track. The Company plans to begin assembly and installation of its hybrid manufacturing system, along with laser and ancillary production and product development equipment, in the first week of July.

“We have received numerous requests for information pertaining to the construction progress of our new facility in Golden,” stated Tom Djokovich, XsunX CEO. “I’m glad to announce that the improvements to the facility are on track for completion this month. We are eagerly awaiting the ability to take possession of our new facility and begin assembling a turnkey product marketing and development infrastructure. In addition to allowing our interested prospects an opportunity to validate our technology, this initial base facility will also provide us with the ability to service requests for limited thin film manufacturing of less than 1 Megawatt annually. Additional benefits of the facility include product prototyping capabilities, which may provide interested licensees with access to cutting-edge building-integrated photovoltaic (BIPV) product development capabilities.”

Mr. Djokovich further stated, “We have been receiving requests from interested manufacturers for systems ranging from 1 to 100 Megawatts of annual production capacities. The interest in thin film manufacturing capabilities appears to be expanding and the completion of this new facility will be invaluable in helping us to shorten the sales cycle with prospects.”

The XsunX manufacturing system is based upon a patented hybrid design combining the scalability of reel-to-reel processing and the use of flexible rolled substrates with the exacting capabilities of cluster tool vacuum deposition systems. These systems can be configured to produce several types of solar cells, such as single junction opaque cells, tandem junction micromorph type cells, and the Company’s proprietary cell designs that include Power Glass films and a new 4-terminal cell that the Company hopes to begin marketing next year as a replacement to more costly silicon wafer technologies.

About XsunX

Based in Aliso Viejo, Calif., XsunX is developing and commercializing innovative new thin film photovoltaic (TFPV) solar cell technologies and manufacturing processes to service expanding global energy demands. The Company has focused its efforts on lowering the cost per watt of solar power and making solar cell technology easier to use in a wide variety of applications. XsunX calls this dual improvement to cost and efficiency the XFactor™. The XFactor delivers licensee’s solar cell designs that break the bounds of crystalline silicon dependency, rigid and limited-use form factors, and rapid efficiency loss. Equally important, the XFactor provides new manufacturing techniques that can significantly lower production costs and allow for easier additions to production capacities and technology upgrades without having to re-build and re-tool. Together, XsunX design and production innovations offer manufacturers of solar products exciting new application opportunities and reductions to the cost per watt of solar power.
