Various embodiments of the present disclosure relate to systems and processes for collecting solar energy. According to particular embodiments, a solar collector device comprises one or more primary reflectors, and a receiver assembly mounted on a frame structure. The receiver assembly comprises one or more secondary concentrators and a heat transfer tube. Each primary reflector comprises a flat elongated mirror mounted on a structural backing that is rotatably coupled to the frame structure such that each primary reflector may pivot around a pivot axis. The receiver assembly may translate along the frame structure in a direction that is parallel to the pivot axes of the one or more primary reflectors. The one or more primary reflectors reflect light focused upon the receiver assembly such that heat energy from the reflected light is transferred to a heat transfer fluid in the heat transfer tube.
