Abstract: The solar tracking arrangement enables a plurality of parallel arranged PTCs to be directed towards the travelling sun. The solar tracking arrangement comprises a drive means, a transmission means, and a plurality of conversion means. The transmission means are connected with the drive means and to each of the plurality of conversion means. The transmission means is configured to convey an operating movement caused by the drive means to the plurality of conversion means, and each of the conversion means is configured to convert the conveyed operating movement into a pivoting movement of a respective one of the plurality of PTCs about a focus line, such that each of the pivoting movements directs the respective PTC towards the travelling sun. One or more of the conversion means are adjustably connected with the transmission means in a direction along the transmission means.

Abstract: An apparatus is disclosed for rotating equipment, like solar panels, about an axis. Tension and compression members, in a rigid structure, are employed in the apparatus to minimize weight and to maximize stiffness. The rotating equipment is attached to the upper end of a rotatable elongated compression member, rotatably supported at its lower end by a tri-pod base comprising three additional compression members. Six tension members extending up from the tripod base hold a flange through which passes the rotatable elongated compression member. Lateral forces on the rotatable equipment are transmitted to the tripod base through the six tension members. The apparatus is configured such that wind forces and torques on the rotated equipment are transmitted by the apparatus to ground supports. Solar panels supported by the apparatus may be held at a fixed tilt angle, or an additional mechanism may be provided for rotational about a second orthogonal axis.

A controller for storing and executing a set of instruction controls the shape of the concentrator to focus the reflected concentrated light rays onto a focal collector. A mirror point list adjusts the shape of the concentrator based on a sun angle.

Abstract: The present invention relates to concentrating solar-power systems and, more particularly, beam-forming concentrating solar thermal array power systems. A solar thermal array power system is provided, including a plurality of solar concentrators arranged in pods. Each solar concentrator includes a solar collector, one or more beam-forming elements, and one or more beam-steering elements. The solar collector is dimensioned to collect and divert incoming rays of sunlight. The beam-forming elements intercept the diverted rays of sunlight, and are shaped to concentrate the rays of sunlight into a beam. The steering elements are shaped, dimensioned, positioned, and/or oriented to deflect the beam toward a beam output path. The beams from the concentrators are converted to heat at a receiver, and the heat may be temporarily stored or directly used to generate electricity.

Abstract: Systems and methods for directly monitoring energy flux of a solar receiver in a solar energy-based power generation system include measuring infrared radiation emanating from the solar receiver. Such measurement can be achieved using one or more infrared thermography detectors, such as an IR camera. Resulting thermal data obtained by the imaging can be used to determine energy flux distribution on the receiver. A user or a system controller can use the determined flux distribution to adjust heliostat aiming to achieve a desired operation condition. For example, heliostats can be adjusted to achieve a uniform energy flux distribution across the external surface of the receiver and/or to maximize heat transfer to a fluid flowing through the receiver within system operating limits.

Abstract: The disclosed invention is a solar tracker that is a simple 2 axis system that can be powered with integrated stepping motors and lead screw actuators that provides the necessary structural support and 2 degrees of freedom in the motion of the solar collector, to increase the electrical output of the system. Since the solution is designed for use with only one solar panel the mechanical forces such as wind load are much lower and easier to manage. The disclosed invention is also a solar tracker that is a single axis version where the base is fixed and the elevation is set at an average value for the location and pivoting mechanism operates the azimuth axis. Since the dominant energy improvement comes from tracking the azimuth, this would be a likely solution where a lower cost or less complex system is desired.
