Installation of solar trackers and photo-voltaic modules complete

Just last week the Prime Contractor Conergy Canada and construction manager SkyFire Energy completed the installation of all 4,032 photo-voltaic modules.

Modules are now arranged in ninety six 38 foot X 20 foot tables and have been mounted on masts topped with a specialized tracking system that will rotate to track the sun. There are 42 photovoltaic modules per table top. Once the installation and commissioning is complete the table tops in the picture will tilt at similar angles to maximize solar exposure and energy generation.

The trackers are considered a “best in class” system whose unique light sensing technology measures conditions and calculates the optimal angle of tilt in two dimensions.

Trackers provide approximately 30% more energy than fixed panels. The trackers' sensors also feature load sensing capabilities and will increase the tilt angle to dump snow as needed and adjust the tilt angle to reduce windload. Performance will be digitally monitored by a data acquisition and monitoring system.

Construction continues on pace for operation in early 2015. In parallel to the tracker installation, trenching and installation of cabling is complete and electricians have begun wiring the trackers and connecting the string inverters that convert the suns energy into electricity that is suitable for delivery via a powerline to the BC Hydro system. String inverters allow for segmented power production in the solar array, providing more power production than centralized inverters which have been historically more popular.

Upcoming activities include installation of the powerline connecting SunMine to the Teck Kimberley substation and BC Hydro, and modifications to the substation itself.
