Solar Tracking Application - Rockwell Automation
literature.rockwellautomation.comapplications, single axis trackers are used with parabolic and linear Fresnel mirror designs. Dual axis Solar trackers have both a horizontal and a vertical axis and thus they can track the sun's apparent motion virtually anywhere in the world. CSP applications using dual axis tracking include solar power towers and dish (Stirling engine) systems.
