Mechatron Solar says its massive dual-axis solar trackers have gained UL certification

California — Mechatron Solar has gained certification for ANSI/UL3703 solar tracker standard for its unique 90-panel dual-axis tracker, the M18KD.

The certification also covers the M18KD-20 carport canopy tracker. The certification was issued by SolarPTL, based in Tempe, AZ, one of four Nationally Recognized Testing Laboratories (NRTL) in the United States.

At the same time, the M18KD was certified under applicable UL 2703 subsections for Mechatron’s proprietary MechGrip clamping device that serves as a grounding bond. Without this certification, some states require separate – and expensive — grounding bond systems, an expanding requirement trend across the country.

The certifications showed that the M18KD tracker works across an Ambient Temperature Range of -40 degrees C to +70 degrees C. The tracker controls are NEMA 4 Outdoor certified with a Power Supply of 3-Phase/N/PE, 230/400V AC +/- 10%, at 50-60 Hz.

In other analysis, the M18KD has been calculated to be capable of wind resistance up to 115 mph, the wind speed of a Category 3 hurricane. The wind resistance calculations and the UL 3703 certification will be featured in the new Mechatron Solar Tier 1 bankability study, slated for
Q2 2022 issuance.

The unusually high-yield M18KD tracker – generating 40% more energy than ground-mount and 20% more than single-axis — has the highest energy density of all solar mounting designs. The tracker also has the lowest ground footprint in the global solar market with a single mast, ideal for carports and other constrained sites.

The M18KD tracker has been installed across 90 MW in Europe and in North America over the past decade. Mechatron sources its components globally, with overlapping country vendors, to assure timely project execution.
