KMI Passes Ultra-Stringent NEXTracker Reliability Testing for Slew Drives


August 9, 2017, Phoenix, Arizona- Kinematics announced today that Kinematics Manufacturing Incorporated (KMI) has become the first slew gear supplier to complete rigorous design verification testing in accordance with NEXTracker’s™ stringent component lifetime reliability requirements. This achievement demonstrates that KMI is providing the most bankable and lowest risk actuation components in the industry.

“NEXTracker is the global leader in solar tracking and works closely with its suppliers to maximize quality while continually innovating,” said Mark Henderson, CEO of Kinematics. “The test protocol developed by NEXTracker was by far the most rigorous, comprehensive, and demanding set of testing we have seen to evaluate every conceivable aspect of quality and long-term durability for tracker gears. We were very pleased that our current and prior generation of drive passed this test protocol, and customers should have comfort that these gears will be providing very long services lives for this important solar tracking application.”

Testing was performed at KMI’s Validation Lab (KVL), the world’s largest and most comprehensive slew drive test facility, with audit and review by senior NEXTracker engineers. KMI developed, and invested in, specialized facilities and equipment for the tests required by NEXTracker. The NEXTracker test protocol focuses on durability, ultimate and dynamic (wind load) strength and environmental survivability.

“NEXTracker remains committed to producing the best performing trackers in the industry,” said Alex Au, Chief Technology Officer of NEXTracker. “By partnering with world class component manufacturers like KMI, we continue to uphold our legacy of delivering innovative trackers with high performance and availability.”

KMI also announced it has delivered hundreds of thousands of gear drives to NEXTracker’s projects worldwide since supplying drives to NEXTracker for their earliest prototypes.
