Independent Analysis Finds Array’s Trackers to Have Lowest Cost of Ownership Driven by Highest Reliability

TÜV Rheinland PTL (TÜV), an independent analyst, recently released a report on the economic and risk analysis of two tracker architectures. The first architecture studied is a system driven by a single motor, linked by a rotating driveline to multiple tracker rows. The second architecture is a system where each row operates as a self-contained unit with a dedicated photovoltaic (PV) panel, battery, motor, and other tracker system components.

TÜV’s report includes descriptions of the technical characteristics of each system, followed by a failure modes and effects analysis (FMEA). TÜV’s methodology assesses risk associated with component failures, and concludes with a levelized cost of energy (LCOE) / Net Present Value (NPV) analysis, highlighting the economic impact of the two technologies on developers, owners, financiers, and insurers of utility scale solar power plants.

The report highlights the following benefits of Array’s tracking technology over the competing architecture:

6.7% Lower Levelized Cost of Energy (LCOE)

31% Lower Lifetime Operation and Maintenance (O&M) Costs

4 Cents/Watt DC Higher Net Present Value (NPV)

Unscheduled Maintenance Events 1/Year Versus 2/Day

  • “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 there are significant differences in OPEX costs between tracker architectures. We believe that the engineered simplicity in our trackers truly is the best long-term option for solar project owners.”
