Module Flexibility for Single-Axis Trackers A study on FlexRail™ and other tools for addressing solar module changes during project design

Utility-scale solar projects face growing uncertainty in PV module supply, driven by global tariffs, supply chain disruptions, and shifting price dynamics. Many projects are initially designed around a specific module, only to confront costly module changes later in development. While most single-axis tracker systems can accommodate different modules during early design, structural incompatibilities often emerge once components are manufactured, leading to delays, redesigns, and added expense. This paper highlights how tracker flexibility can preserve project economics by reducing the risks associated with late-stage module substitutions.
