Solar tracking installation includes first movement assembly which functionally engages with the primary axis shaft to cause rotation of the primary axis shaft around the primary axis for moving the plurality of planar modules of solar collector elements in a first rotational direction around the primary axis. The installation further includes a second movement assembly which functionally engages with the secondary movement member to cause tilting of each of the plurality of planar modules of solar collector elements around each respective pivotal mount. In this way the movement of the multitude of solar collection elements is a combination of the rotation of first movement assembly and the tilting motion caused by the second movement assembly.

A rack, especially for photovoltaic modules, consists of a rounded, shaped guide, on which a main frame is fitted via at least three bearing-fitted grips, with an upper frame being attached to the top of the main frame in at least two support points, the upper frame being further connected to the main frame via linear actuators. The main frame is based on the guide by means of track rollers, whose number is equal to the number of support points, and at least two anchoring elements are located on the outer perimeter of the guide, the anchoring elements arranged in at least two points within an angular distance not smaller than 15 degrees from each other. A driving chain is anchored in a non-stationary fashion on anchoring elements to the guide, from the outer side of the guide and in the lower part of the guide, and a driving mechanism is attached to the main frame, the driving mechanism consisting of a driving toothed element, connected to a motor, and of tension rollers.

A mounting system for a heliostat is provided that allows the heliostat to move with respect to two orthogonal axes to track the sun. The mounting system has features that allow the heliostat to precisely and accurately move about these axes even as various components degrade during operation in harsh environments and over long time periods. Embodiments of the mounting system can have a frame that supports multiple mirrors and translates forces from the mirrors to multiple hubs that move about a circular track. One of the hubs can include a fewer number of contact points to accommodate a circular track that is out of round. In addition, an actuator that moves the hubs around the circular track can be biased into the track to also accommodate a circular track that is out of round.

A system for guiding the rotation of a solar tracker includes a system (1) for guiding the rotation of a solar tracker, having at least one arch (2) that can be mounted on the solar tracker and can rotate about an axis of rotation (100), and at least two guide devices (3) configured to guide the rotation of the arch (2).

Methods and apparatus for concentrating electromagnetic waves coming from a moving source at a focal point fixed to the ground. The invention discloses a tracking system for a device capable of concentrating incoming electromagnetic waves at a fixed focal point. This concentration of the electromagnetic waves may be done by reflection, as in the case of a reflecting dish, or by refraction as in the case of a concentrating lens, which is impeded in a hemisphere, which can be real or imaginary, such that its focal point coincides with the center of the hemisphere and using this apparatus to track such moving source by rotating around said hemisphere's fixed center, so as to face the incoming electromagnetic rays normally. A receiver can be kept at the focal point of the device which uses the concentrated rays for various applications such as melting metals or charging a solar cell.

Systems and methods that provide trackers and tracking assemblies having node managers, such as smart node managers are described herein. Aspects of the disclosure are directed to an autonomous energy distribution network including a plurality of solar tracker devices configured to receive solar energy and transform the solar energy into electrical energy, where each of the solar tracker devices is directly connected to a node in a power distribution grid. The network also includes a node manager configured to receive status information from the solar trackers, where the status information includes information regarding the state of the node to which each of the solar tracker device are directly connected.
