Single-axis trackers enhance solar energy yield by following the sun, even in challenging environments. Progressive wind stow and terrain optimized backtracking strategies significantly reduce energy loss, improving performance in high winds and uneven terrains. With the proliferation of solar power plants worldwide, single axis trackers are proving an invaluable resource. Rotating solar panels throughout the day to follow the sun increases energy yield, providing more consis

Understanding fatigue loading on purlins for single axis trackers Solar power plants are increasingly being designed and installed in hurricane-prone and otherwise high wind speed locations. The structure supporting PV modules on these plants must sustain significant levels of repeated wind loads. Over time the cycling of wind load accumulates as fatigue load. A study commissioned by GameChange Solar and performed by CPP Wind Engineering Consultants shows that fatigue loading

Hail damage is one of the most significant threats to utility-scale solar installations, particularly in regions prone to severe weather. As hail risk gains greater attention from developers, investors, and insurers, solar tracker systems have become essential tools for reducing PV module hail damage through intelligent hail stow strategies. GameChange Solar’s white paper, “Reliable Hail Mitigation,” outlines how sound engineering design and risk-based decision-making can dra

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,
