North of the 39^{th<\/sup> parallel near Halifax, Nova Scotia, an area familiar with harsh winter conditions, low sun angle, and coastal-related degradation concerns, a dynamic solar array has been installed. A Halifax estate owner hired the Aartha Group of Surrey, British Columbia, to construct a solution that uses a Mechatron dual-axis tracker.<\/p>\n\n\n\n}

The tracking mount, according to Aartha Group, has performed better than most tracker technologies in northern climates. The group cites the tracker\u2019s near-vertical positioning capability as an effective method for snow-shedding.<\/p>\n\n\n\n

The Mechatron structure was also selected for its expected reliability. Its gearless design is expected to be an advantage over a typical geared structure. Other designs have had occurrences of shattered gears in conditions of extreme cold and high wind.<\/p>\n\n\n\n

The array includes 90 Canadian Solar bifacial 390W panels, which allows the panels to gather solar irradiance reflecting back from the snow, or from the light-gray gravel substrate beneath the mount.<\/p>\n\n\n\n

The estate owner claims a 20% increase in output from the bifacial panels. This, combined with the 35% increase in production due to the dual-axis tracker, as opposed to a fixed-mount, has led to what the owner claims is a nearly 50% increase in production.<\/p>\n\n\n\n
