GameChange Solar, a leading global provider of solar tracker and fixed-tilt racking systems, announces the release of FlexRail, a mounting system specifically designed to enhance the flexibility of module selection. FlexRail addresses one of the industry's most pressing challenges: solar module supply volatility driven by tariffs, logistics delays, and global market fluctuations. Projects frequently face costly redesigns or field modifications when PV modules change after trackers have been manufactured or installed. GameChange Solar's FlexRail mounting system allows the same tracker design to accommodate multiple different modules with minimal disruption.

"Module supply is one of the most dynamic variables in utility-scale solar today," said Nat Healy, Genius Tracker Product Director. "By supplying trackers designed to support a wide range of module types, we help our customers maintain project schedules and protect their financial models, even when the customer changes modules late in the design or installation process."
The advantages of FlexRail and the other facets of the Genius Tracker single-axis tracking system are described in GameChange's latest white paper, Module Flexibility for Single-Axis Trackers: A study on FlexRails and other tools for addressing module changes during project design. The paper examines key design features that enhance module flexibility, including clamp-based rail systems, flexible purlins, unpunched torque tubes, and low-profile bearings. These elements enable utility-scale solar projects to adapt to shifting PV module availability while maintaining cost efficiency and construction schedules.
The Module Flexibility white paper provides practical insights for developers, EPCs, engineers, and investors navigating today's volatile module supply chain.
