Public water agency in Palm Springs uses Xantrex solar inverters

Two industrial solar inverters designed and manufactured by Xantrex are included in a 355 kW solar electric system that is now installed at Desert Water Agency, a public water agency in southern California. It is the largest industrial solar power installation in Palm Springs.

VANCOUVER, BC and PALM SPRINGS, CA, April 26, 2005 - Two industrial solar inverters designed and manufactured by Xantrex Technology Inc. (TSX:XTX) are included in a 355 kW solar electric system that is now installed at Desert Water Agency, a public water agency in southern California. Located near the agency's operations center, it is the largest industrial solar power installation in Palm Springs.

SoCal Solar Energy Inc. of Mission Viejo, Calif. installed the photovoltaic system, which incorporates over 2,000 Shell PowerMaxTM solar modules from Shell Solar Industries. Xantrex's PV225 inverters are a key component of the system, converting the sun's energy harnessed by the solar panels into alternating current electricity that is used to power the facility.

"Shell Solar has been using Xantrex's commercial-scale solar inverters in our projects since 1995," said Kevin Mackamul, Director of Systems Engineering, Shell Solar Industries. "We have high confidence in Xantrex's inverters because they are reliable and efficient. We also like that Xantrex has a range of transformers for grid-tie applications that are versatile and easy to install."

Sunny Palm Springs is an ideal location for solar energy systems. This installation will serve as a model for natural resources conservation and environmental consciousness to other utility companies said Desert Water Agency General Manager Dave Luker.

"One of the agency's biggest operating expenses is electricity," Luker said. "It takes a significant amount of electricity to run our air-conditioned headquarters and pump water from the groundwater aquifer. With worldwide energy shortages and escalating energy costs, our new solar electric system will decrease operating costs and produce clean, renewable energy at the same time."

With a predicted energy performance of 662,000 kilowatt hours per year, the photovoltaic installation will offset virtually 100% of the operation center's electric bills. The system will save DWA more than $70,000 annually or more than $2.4 million over the life of the system.

Southern California Edison Company Self-Generation Incentive Program also offers rebates to customers that invest in solar power and will provide a rebate to DWA for half of the installed solar system's cost.

Desert Water Agency is a non-profit public water agency that contracts with the State of California to supply water to Palm Springs, parts of Cathedral City and the unincorporated areas of Desert Hot Springs. DWA provides a range of services that emphasize water efficiency and purity including water service, sewer services, engineering and planning, water recycling, and rules and regulations for private wells.
