Commercial application of microalgae as a bio-fuel feedstock has necessitated devising methodologies to optimize growth conditions in promising strains to induce high lipid content for semi-continuous harvest of the biomass.
Developed in 2017, the STI-H250™ is consists of two linked torsion beams that rotate simultaneously following the sun's path. They are moved by just one motor, cutting supply and maintenance costs. STI-H250™ dual-row tracker includes backtracking mode to avoid shadowing between adjacent rows and stow function to protect the tracker in extreme wind conditions. For cleaning, vehicles can pass between trackers and each row can be placed in a different position.
