Solar panel system

摘要

A solar panel assembly having a foundation tube, a rotary actuator mounted in the foundation tube for changing the azimuth of the panel and a linear actuator mounted to the foundation tube for controlling the elevation angle of the panel. The linear actuator utilizes a spindle drive. The rotary actuator includes a motor and gearbox; a drive screw connected to the motor; a spindle screw, one end of which provides an output of the rotary actuator; a drive nut having a first threaded hole for receiving a thread of the drive screw and a second threaded hole for receiving a thread of the spindle screw, the guide nut having a guide fin; and a guide rail interacting with the nut guide fin to constrain the nut from rotating, whereby the rotation of the drive by screw by operation of the motor causes the nut to translate linearly which in turn causes the spindle screw to rotate.
