Array Technologies, a global provider of solar tracking technology products, expanded its SmarTrack software to include backtracking and diffuse optimization capabilities for its Array STI H250 dual-row tracker. This advancement brings algorithm training and optimization tools, which was tested on the DuraTrack platform, to H250 installations across global markets.

“Our H250 tracker has long been a trusted solution in markets with challenging site conditions, and the addition of SmarTrack Backtracking and Diffuse takes its performance to the next level,” said Neil Manning, president and COO of Array. “By applying algorithmic training and real-time sensor data, we’re empowering our customers to optimize their solar energy output across more geographies and more terrain types, ultimately improving project returns.”
The H250 tracker is engineered to tackle the challenges of irregular terrain. SmarTrack Backtracking and Diffuse is designed to improve energy production in complex environments and variable weather conditions. These tools help trackers automatically adjust to minimize shading and maximize light capture, even on cloudy days.
Array SmarTrack Backtracking uses algorithmic training, terrain analysis and production data to reduce shading and increase morning and evening energy generation. The system adjusts each motor block based on its slope characteristics for sustained improvements in energy yield. By analyzing real-time global horizontal irradiance sensor data, the system flattens tracker angles to capture more diffuse light, increasing yields when direct sunlight is limited.
These capabilities were tested in Spain and Brazil and are available for immediate deployment on new and existing H250 projects. In combination with Array’s hardware and integrated software platform, SmarTrack is currently optimizing over 5 GW of solar capacity worldwide.
