The M16KD AgriTracker is manufactured in Stockton, California by Mechatron Solar, that manufactures unique, patented dual-axis photovoltaic trackers. With a ground coverage ratio of 28% to 50% (depending on panel type), the M16KD solution requires only 4 acres per MW of array. The gearless, hydraulic design drives more through 360 degrees of Azimuth rotation and 60 degrees of Zenith inclination.

Highly weather-resistant, the M16KD tracker withstands wind gusts of up to 115 mph; a version with heavier purlins is available for wind speeds up to 135 mph. The M16KD also withstands snow loads of nearly 35 psf, although snow loads have been demonstrated to shed readily in Canadian latitudes.

The flagship M18KD tracker supports 90 solar panels. The company’s unusually high-yield trackers have the highest energy density and the lowest ground footprint in the industry. Mechatron solar trackers include gearless azimuth trackers and gearless dual-axis trackers, which are designed to maximize performance with a lower operations and maintenance cost than other commercially available tracking systems. They have been successfully tested under different climate conditions rate structures constitute the best available solution for photovoltaic plant installations.

Mechatron was certified under UL 3703 in 2022 and completed a bankability analysis by Black & Veatch. The flagship tracker also features a new digital guidance system, along with a new optional design with eight columns to accommodate large format modules. The M10KD residential model features a reduced table size to support 49 panels, to accommodate limited space requirements.
