Who makes trackers for AI data centers

A tracker is the steel and drive system that tilts solar panels to follow the sun through the day. It raises the energy a given array produces, meaningfully so at utility scale, which is why almost all large ground-mounted projects use them rather than fixing panels at a set angle. What makes it more than a mounting bracket is that it is a mechanical system with moving parts in a field, expected to operate for decades with minimal attention, through wind and snow loading and ground that moves. The failure modes that matter are structural rather than electrical: wind-induced motion that tears an array apart has destroyed projects, and the aerodynamic and control design that stows the array in high wind is the part that earns the price difference between suppliers. For this catalog the relevance is indirect but the economics are direct: tracker yield gain changes the cost of the energy in a power purchase agreement an AI operator signs, and tracker steel is a claim on the same fabrication and galvanising capacity that transmission structures and building steel elsewhere in this catalog also draw on. What to look for is wind-tunnel and field validation of the stow strategy, the foundation approach given the site's soils, and whether the supplier is manufacturing or designing and outsourcing — this is a steel-intensive product where logistics cost is a real share of delivered price.
