Saskatchewan Science Centre

Saskatchewan Science Centre, Regina, Carmanah rooftop solar photovoltaic system
Capacity (kW): 
Regina , SK
Commercial Operation: 

The first 3-phase solar power system in Western Canada was installed at the Saskatchewan Science Centre, Regina. Led by SaskPower, the project contracted Carmanah to provide a turn-key solar and inverter system solution.

The Science Centre operated without interruption during the installation, and shows the ease of integrating grid-tied solar power for commercial applications. In operation, the power produced by the solar array feeds into the building in harmony with the traditional grid-power provided by SaskPower.

This turn-key system will provide an educational showcase on solar energy for visitors to the Saskatchewan Science Centre.

A 2800 W solar array, constructed of 28 Shell 100 W modules and roof mounts, was designed and installed by Carmanah in conjunction with Sun Electric, a local electrical contractor. The PV5208 three-phase inverter, from Xantrex Technologies Inc., interfaces the solar array with the utility grid. This 5 kW inverter provides overall system control with a variety of protective and safety features.

The higher voltage capability of the three-phase system is more appropriate for commercial entities, such as the Science Centre, compared to the residential norm of single-phase.
