A solar collector tracking system that has a solar collection device having multiple lens assemblies mounted on its front surface. An exoskeleton structure is secured to the rear surface of the solar collection device and it is pivotally secured about a horizontal axis to the front end of an azimuth platform assembly. A hydraulic elevation actuator is pivotally mounted in the azimuth platform assembly about a horizontal axis and the front end of its piston rod is pivotally connected to the rear surface of the solar collection device and this allows it to be pivoted approximately 90 degrees between a vertical operating position and a horizontal storage position. The azimuth platform assembly is journaled on the top end of a tower extending up from the ground. A tubular post is rigidly secured to the top end of the post. A drive head extends horizontally from the tubular post and it has a pivot pin that extends upwardly therefrom. A primary and a secondary azimuth hydraulic actuator have the front ends of their respective piston rods coupled to the pivot pin. The opposite ends of the azimuth hydraulic actuators are pivotally secured to the interior of the azimuth platform assembly. A hydraulic power unit is connected to the respective hydraulic actuators. An electronic controller monitors signals from an azimuth encoder sensor and an elevation encoder sensor and it directs the respective hydraulic actuators to move their respective piston rods inwardly and outwardly so that the solar collection device can be rotated to track the rays of the sun.
