ALBUQUERQUE, N.M., Sept. 8, 2017 /PRNewswire/ — Array Technologies, the world’s most trusted name in solar tracking, recently announced the results of an independent analysis by inspection services provider, TÜV Rheinland. This in-depth study indicates that Array’s flagship tracker, the DuraTrack® HZ v3, is 300 × less likely to experience catastrophic failure during wind events than single-row competitors that rely on stow.

“Reliability is the cornerstone of responsible solar industry growth,” said Array Technologies CEO and founder Ron Corio. “Without dependable PV modules and tracking systems, the solar industry will struggle to continue down its path of innovation and expansion. This third-party validation from TÜV confirms what we have been claiming for nearly 30 years: that the engineered simplicity in our trackers truly is the best long-term option for solar project owners.”

Array Technologies designs its solar trackers with the highest structural integrity. Built with a robust design and a unique wind mitigation strategy, Array’s trackers effectively avoid module stress, fatigue failure and torsional galloping issues during high stress wind events. The DuraTrack HZ v3 withstands environmental pressures in all positions and, unlike the competition, does not depend on a complicated chain of electronic stow commands. TÜV’s inclusive report finds Array to offer higher operational uptime and lower scheduled and unscheduled maintenance costs to site owners.

TÜV analysts performed an economic and risk analysis of two tracker architectures: one layout driven by a single motor linked by a rotating driveline to multiple tracker rows; and a competing design where tracker rows operate as self-contained units, each with a dedicated photovoltaic (PV) panel, battery, motor and other system components. TÜV’s analysis includes descriptions of the technical characteristics of each system, followed by a failure modes and effects analysis (FMEA) to assess risk associated with component failures, and concluding with a levelized cost of energy (LCOE) / Net Present Value (NPV) analysis to assess the economic impact of the two technologies on developers, owners, financiers, and insurers of utility scale solar power plants.

The TÜV report also highlighted the below benefits of Array’s tracking technology:

  • 7% lower LCOE (Levelized Cost Of Energy)
  • 4.5% higher NPV (Net Present Value)
  • 15% lower scheduled O&M cost
  • 130 × lower unscheduled O&M cost

“At TÜV Rheinland, we pride ourselves on unbiased and high-quality research and reporting,” said Mark Skidmore, Regional Field Manager, Solar-North America of TÜV Rheinland. “We routinely put technologies across the solar tracker industry through rigourous testing to challenge the industry’s biggest players to go above and beyond with the reliability of their designs. Together, we can sustainably grow the global solar tracking market.”

The DuraTrack HZ v3 is currently available to solar project developers. For more information about the tracker or the results of the TÜV Rheinland study, please visit:
