The first three-phase solar system in western Canada has been installed at the Saskatchewan Science Centre in Regina.REGINA, Saskatchewan, CA, 2001-10-05 [SolarAccess.com] The 2.8 kilowatt system has 28 Siemens PV modules and roof mounts, and is designed to provide an educational showcase on solar energy for visitors to the facility. The array was designed and installed by Soltek Solar Energy Ltd., in conjunction with local contractor Sun Electric, under contract to SaskPower, the provincial electric utility. “We’re really pleased to work with SaskPower on the Saskatchewan Science Center Project,” says Steve Wiebe of Soltek. “Together we planned an installation that would minimize the impact on the Science Center’s normal operation.” The Center operated without interruption during the installation, and Wiebe says the success shows the ease of integrating grid-tied solar power for commercial applications. “This was a challenging turn-key project,” he explains. “Upfront work with SaskPower allowed the installation to proceed and be completed in only two days.” The PV5208 three-phase inverter, from Xantrex Technology, links the PV array with the grid. The 5 kW unit provides overall system control with a variety of protective and safety features. The higher voltage capability from a three-phase system is more appropriate for commercial entities, compared to the residential norm of single-phase. Soltek was formed in 1985 and claims to sells one of every two solar modules for the Canadian marketplace. The company is headquartered in Victoria, with offices in Vancouver, Calgary and Montreal.
