  • Patent number: 9069169
    Abstract: The invention is an improved reflective element used with a heliostat or any application where a reflective surface is required to provide low cost, low weight, and will maintain a relatively high degree of planar integrity under changing environmental conditions. The invention is based on a pretensioned backplane with aligned peripheral edges to produce a planar surface that a membrane material can be extended across and the membrane is securely attached at the bottom of the peripheral edges. This configuration provides a constant tension to the membrane which prevents the membrane from deforming as thermal cycling occurs. The pretension placed on the backplane produces an arching effect that is captured when the membrane is securely attached and remains arched once the backplane is released from the tensioning form. The arching of the backplane provides added strength and rigidity sufficient to minimize the need for additional structural components.

A trough collector system includes at least two modules, each module including a reflector having a reflective surface shaped to concentrate incoming radiation onto a linear tube, and a structural lattice attached to the reflector. The modules are constrained to rotate about a common axis. A torque transfer connection directly connects the three-dimensional structural lattices of the two modules at a location removed from the axis of rotation. Torque is thus transmitted between the modules by a force couple acting on the module. Also described are a method of transferring torque between adjacent trough collector modules, and a three-dimensional structural lattice configured for use in the system and method. Mechanisms for accommodating thermal expansion and contraction of the array are described. A drive system is described that imparts torque to a module near an edge of the module.

  • Publication number: 20130220303
    Abstract: The aim of the invention is to build central receiver solar power plants in which the heliostat fields can be used more efficiently. To achieve said aim, a heliostat field consisting of a near field having a uniform reflector surface density ? of more than 60% is preferably combined with a far field whose reflector surface density ? decreases as the distance from the receiver increases. The invention also comprises central receiver solar power plants which consist exclusively of a near field having a uniform reflector surface density ? of more than 60%. The high reflector surface density ? in the near field and in areas of the far field is achieved by the use of heliostats having rectangular reflectors and a rigid horizontal axle suspension (FHA) or, alternatively, by heliostats having rectangular reflectors and a rigid quasipolar axle suspension (FQA).

  • Publication number: 20130220304
    Abstract: A protective transparent enclosure (such as a glasshouse or a greenhouse) encloses a concentrated solar power system. The concentrated solar power system includes one or more solar concentrators and one or more solar receivers. Thermal power is provided to an industrial process, electrical power is provided to an electrical distribution grid, or both. In some embodiments, the solar concentrators are parabolic trough concentrators with one or more lateral extensions. In some embodiments, the lateral extension is a unilateral extension of the primary parabolic trough shape. In some embodiments, the lateral extensions are movably connected to the primary portion. In some embodiments, the lateral extensions have a focal line separate from the focal line of the base portion. In some embodiments, the greenhouse is a Dutch Venlo style greenhouse.

  • Patent number: 8511297
    Abstract: A system for controlling the rotational position of a solar collector trough includes a hydraulic cylinder having an output end and a linkage assembly. The linkage assembly includes at least one linkage member and a pair of pivot arms attached to the at least one linkage member. The pair of pivot arms is defined by a first pivot arm and a second pivot arm, each arm being pivotally attached to the at least one linkage member and the trough. The first and second pivot arms form respective parallel horizontal first and second pivot axes enabling the trough to be entirely movable over an angular range of motion extending over 180 degrees based totally on the linear movement of the output end of the hydraulic cylinder and in which an actuator control circuit controls the relative displacement of the cylinder output end.

  • Patent number: 8490618
    Abstract: A solar energy conversion system may include a receiver with a first heat transfer fluid channel having at least two opposite sides. Each side may present an external surface facing in a direction opposite to that of the external surface of the other opposite side. Each side may be configured to contact a heat transfer fluid carried in the first heat transfer fluid channel. A heliostat field may be configured to direct solar energy to each of the at least two opposite sides during the course of a day such that a thermal stress tending to bend the channel remains below a specified level.

  • Patent number: 8471187
    Abstract: An improved solar concentrating system (100) uses a two-stage arrangement of mirrors wherein the rays of the sun are reflected and concentrated to a point focus. The solar concentrator (100) may be used to increase the temperature of a substance such as metal, for use in a variety of applications including the melting of metals in a foundry furnace. The solar concentrating system (100) comprises at least two single-curved parabolic mirrors (10, 20) connected in an operable arrangement. The rays of the sun are reflected from a first single-curved parabolic mirror (10) to a second single-curved parabolic mirror (20). The plane of symmetry of the second single-curved parabolic mirror is arranged substantially orthogonal to the plane of symmetry of the first single-curved parabolic mirror thereby concentrating the rays of the sun to a point focus.

  • Patent number: 8469023
    Abstract: Disclosed is a radiation collector comprising a pressure cell which is subdivided into a first pressure chamber and a second pressure chamber by means of the concentrator. The small pressure difference between the pressure chambers keeps the concentrator operational in a beam-concentrating form and reduces the wear on the reflective layer of the concentrator. The radiation collector further comprises adequately designed means for establishing the desired pressure in the respective pressure chamber, said means making it possible to compensate changes of the pressure chamber volume resulting from wind load, for example.
