20140182580 | SOLAR COLLECTOR MODULE - Improvements in the design and construction of solar collector modules. Aspects of the invention include improvements in the layout of a frame for a solar collector module, and in the joining of structural members of the frame at nodes. In one example, a module of a solar collector includes a reflector and a three-dimensional structural frame that supports the reflector. The frame is made up of substantially rigid elongate frame members interconnected at nodes. Improved node connection components include hubs or frame members having tabs for receiving frame member connections. A tab may have a width that is substantial in relation to its height. The frame may incorporate asymmetry in its layout, in the size or presence of frame members, or in the positioning of the nodes. | 07-03-2014 |
20140144428 | STRUCTURAL FRAME AND SOLAR COLLECTOR MODULE - Solar collector modules and techniques for their construction are disclosed. In one aspect, a solar collector module includes a reflector and a three-dimensional structural frame that supports the reflector. The structural frame includes a set of primary structural shapes and a set of axial frame members connected between corners of the primary structural shapes forming helical paths for the transmission of torque from one end of the structural frame to the other. In another aspect, a method for assembling a solar collector module includes pre-assembling part of the module. | 05-29-2014 |
20140034042 | TROUGH SOLAR COLLECTOR MODULE - A concentrating solar collector module includes improvements in performance and assemblability. In one configuration, the module includes a reflector having a reflective front surface shaped to concentrate incoming solar radiation onto a focal line, first and second rails, one rail attached to each edge of the reflector, and a set of truss connectors attached to the rails. The truss connectors and rails may form ways that enable constrained sliding engagement of the truss connectors along the rails before attachment of the truss connectors to the rails. The module may also include a plurality of framing members connected to the truss connectors and forming a structural lattice that cooperates with the reflector to lend rigidity to the solar collector module. At least some of the framing members may be disposed in front of the front reflective surface. | 02-06-2014 |
20130074831 | TORQUE TRANSFER BETWEEN TROUGH COLLECTOR MODULES - A system for transferring torque between modules in a concentrating solar collector array. 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. | 03-28-2013 |
