The DuraTrack HZ v3 is the latest generation of solar tracker developed by Array Technologies. It has added a set of software algorithms dubbed SmarTrack in its solar trackers thus enhancing the system ability to react to weather and site conditions.
SmarTrack is an optimization technology that intelligently adjusts solar module angles to optimize backtracking power production on as-built project conditions to capture the maximum power yields during diffuse light conditions, the company says.
They have created a suite of software which consists of three separate machine-learning algorithms, all of which are fine-tuned to maximize power output in different scenarios.
One algorithm controls backtracking. The second algorithm controls diffuse light and And the third algorithm controls bifacial and split-cell response. Bifacial tracking promises significantly higher power yields — anywhere from 10 percent to 50 percent or higher.
Bifacial panels work best on solar trackers, since the source of sunlight moves during the day, it is best captured by the moving tracker mechanism.
Analyst predict that the market share for bifacial tracker systems will expand from a near-zero base today to a projected 10 percent market share in 2019, and a 30 percent market share by 2025, compared with monofacial panels. “That would represent a $20 billion to $110 billion market for bifacial technology.
