The present invention relates to a tracking-type photovoltaic generator. More particularly, the present invention relates to a tracking-type photovoltaic generator in which multiple solar modules are aligned into one or more rows so as to form a group, and the solar modules of the group aligned in the same row may rotate according to the location of the sun by means of the operation of a linear actuator.

A solar tracker comprises a support frame, a panel assembly comprising one or more solar panels, and an actuator to rotate the panel assembly to track the movement of the sun. The panel assembly comprises a central spine and one or more panel carriers extending transversely over the top of the central spine for supporting solar panels. The panel carriers are secured to the central spine by respective support brackets. The support brackets comprise a top surface, side walls extending downwardly from opposing sides of the top surface, and a slot with a downwardly facing opening extending transversely through the sidewalls. The slot is configured to receive the central spine.

A panel driving device rotates a panel structure to vary a tilt thereof or turns the panel structure about a vertical axis, the panel structure including a panel for receiving sunlight, the panel driving device including: a drive source including a rotational portion capable of rotating; and a transmission mechanism including a connection portion connected to the panel structure, and configured to convert a rotational movement of the rotational portion into rotation or turning of the panel structure without converting the rotational movement of the rotational portion into a linear movement, wherein the connection portion is offset from a rotation axis of the rotational portion.

A dual axis solar tracker is provided. The dual axis solar tracker includes a moving platform, a fixed platform, a serial chain, a parallel chain and a driving device. The moving platform is supported by the serial chain and driven by the parallel chain, forming a parallel tracking mechanism. The driving device is configured to drive the parallel chain to motion so as to drive the moving platform to rotate around vertical and horizontal axes. The dual axis solar tracker of the present disclosure has a larger workspace, a better tracking performance and advantages of high rigidity, low energy consumption, small driving torque and low inertia, etc.

A solar tracking system with a plurality of tracking assemblies moved by a single motor. A method and system that prevents overloading the motor or tripping a circuit breaker due to an obstructed or impeded tracker includes sensing movement of the tracker assemblies and entering into obstruction clearing modes. Obstruction clearing mode 1 (OCM1) is a high frequency adjustable mode that prompts movement for an adjustable period of time. If movement commences, the system returns to a normal mode. If there is no movement, the system enters into an obstruction clearing mode 2 (OCM2) with is an adjustable lower frequency series of attempts. If there is no movement, no further attempts are made. Each of these steps are monitored and controlled remotely. There are two types of secure connections for drivelines, torque tubes or affixing driveline linkages for high torque conditions.

The present disclosure envisages a solar tracking system for a solar panel. The solar tracking system comprises a bearing, a torque tube and a linear actuator. The bearing is coupled to the solar panel by means of rails, typically, C-channel, hat section rails. The torque tube is connected to the solar panel, wherein the torque tube is configured to be angularly displaced within the bearing. The linear actuator is coupled to the torque tube, wherein the linear actuator is configured to angularly displace the torque tube, thereby displacing the solar panel. The linear actuator includes a worm and worm gear arrangement of a rack and pinion arrangement. The solar tracking system is powered by either an auxiliary solar panel and/or a battery.
