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:
“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.”
