Trackers are used at scale but it depends where. If a solar plant isn't intended to maximize output because peak prices can be negative, then there isn't much point. However at locations where something other than price is a driving factor, trackers are common enough at grid-scale facilities. The energy market systems are somewhat distorting perceptions of power in general and some reliability planners are worried that as older dispatchable generation goes offline for good, rotating blackouts may be in the future for many high demand areas.
