Xantrex(TM) Signs Strategic Supply Agreement With SunEdison Valued at Approximately US$5 Million

Market Wire, July, 2008

Xantrex Technology Inc. (TSX: XTX) announces it has signed a supply agreement with Sun Edison LLC, one of North America's largest solar energy service providers. Under the agreement valued at approximately US$5 million, Xantrex will supply commercial three-phase solar power inverters in various sizes to be installed in SunEdison solar projects over the next 12 months.

"We are delighted to move forward with this strategic partnership with SunEdison," said Mossadiq S. Umedaly, Xantrex Chairman. "This relationship will put Xantrex inverters into major commercial, government and utility sites across North America."

Xantrex commercial solar inverters efficiently convert direct current (DC) energy collected by solar modules into high quality alternating current (AC) electricity for delivery to the power grid. SunEdison has been using Xantrex commercial grid-tie solar inverters for the past year, following an initial purchase order for the Alamosa project in late 2006. This new supply agreement is the result of Xantrex's proven product quality and Xantrex meeting the strict standards that SunEdison requires of its vendors.

"SunEdison has used Xantrex inverters in some of our key deployments, including our 8.2 MW Alamosa plant," said Thomas (Tom) Rainwater, CEO of SunEdison. "As a leading manufacturer of inverters, Xantrex adheres to utility-industry standards - a key component in our decision to use their products."

Xantrex CEO John Wallace added, "This partnership provides SunEdison with proven and reliable products in the commercial solar market. We are confident that Xantrex's product expertise, coupled with SunEdison's strong brand presence and excellent market understanding will ensure mutual success in the solar market."
