Systems, apparatuses, and methods are described for vertical solar panels. Prefabricated and/or preassembled solar panels may be deployed fast, for example, by using a special packaging. Support structures may be easily installed to support (e.g., hang) the solar panels. The solar panels may be pretensioned and/or comprise structural designs (e.g., holes, frames, flexibility, etc.) to have reliability and/or longevity under a hanging condition and wind impact. The heights of vertically-installed solar panels may be dynamically adjusted, for example, based on inputs from sensors and/or time of day. Inter-row shading may be changed based on height adjustment among multiple rows of vertical solar panels.

The invention relates to enclosed solar parabolic trough reflector systems for thermal heat generation that can ultimately be used in various applications. The system includes a modular dual arch building design with a transparent building envelope and a reflector assembly connected within the building through a bearing assembly. The system is particularly suited for solar heat collection in harsh environment.

A solar generator apparatus includes: a generator module having first to fourth corner portions; a middle column mounted on a fixed structure and pivotally connected to the generator module; first and second winding devices attached to the middle column; first to fourth cables; and first to fourth elastic anchors. The first to fourth cables have first ends respectively connected to the first to fourth corner portions. The first and third cables are wound around the first winding device. The second and fourth cables are wound around the second winding device. The first to fourth elastic anchors are elastically mounted on the fixed structure. The first to fourth cables respectively pass through the first to fourth elastic anchors to form two W-shaped structures. Each elastic anchor includes an elastic member and a restricting member connected in parallel. The restricting member restricts a maximum deformation amount of the elastic member.

A glass concentrator mirror assembly and a method for making same. A glass concentrator mirror assembly is configured to reflect sunlight to a receiver in a reflector assembly. The glass concentrator mirror assembly has at least one glass mirror. The at least one glass mirror has a reflective side and a back side. The glass concentrator mirror assembly also has a parabola-forming frame structure for the at least one glass mirror. The parabola-forming frame structure includes a sternum that is fixedly fastened to a spine with the at least one glass mirror therebetween. The parabola-forming frame structure facilitates a substantially parabolic curvature of the at least one glass mirror. The parabola-forming frame structure provides a substantially uniform force along a line of contact between the sternum and the at least one glass mirror.

A heliostat apparatus includes one mirror frame supporting a reflecting mirror; a pair of north-south rotational shafts to rotate the mirror frame in the north-south direction; an east-west rotational shaft to rotate the mirror frame in the east-west direction with the north-south direction as the rotational axis direction; a pair of arms projecting from the east-west rotational shaft to the east and west; an east-west rotational shaft support allowing east-west rotational shaft axial rotation; and the north-south rotational shafts positioned to face each other on the ends of the arms. The mirror frame rotation, etc. as an integrated unit in the east-west direction with the east-west rotational shaft as the rotational axis adjusts a reflecting mirror reflecting surface east-west angle. With the north-south rotational shaft as the rotational axis, the mirror frame rotation in the north-south direction adjusts the north-south angle of at least one reflecting mirror reflecting surface.

A torque tube coupler that rigidly connects reflectors and provides for substantially 360 rotational freedom for the reflectors as well as the ability to transmit rotation from one reflector to another so that the reflectors may essentially be placed at the same angle. The torque coupler includes first and second torque tube coupler assemblies each configured to be connected to a reflector in a solar energy collection system. The torque coupler also includes a support point that supports said first torque coupler assembly and said second torque tube coupler assembly. This support point includes a shaft that facilitates the rigid connection of the first torque tube coupler assembly to the second torque tube coupler assembly and a bearing that facilitates 360 rotation of the first reflector and the second reflector.

A cable drive system for solar tracking for solar array systems. The cable drive system employs one or more cables wound around a drive pulley of a drive device and one or more driven pulleys of respective rotatable solar assemblies of the solar array system. The system may use a tension device such as a spring or weight that returns the solar array system to an initial position at the end of the day. The drive device may be an active or passive solar tracker. The disclosed techniques of rotating solar panels are flexible, inexpensive, and reliable. The techniques can apply to any solar technology that benefit from following the sun.

The present specification relates to a solar collector having Fresnel mirrors including a mounting for a set of mirrors made up of strips of mirrors referred to as primary mirrors, each pivoting about a respective axis of rotation referred to as the large axis relative to the mounting, and intended for collecting solar radiation and for concentrating said radiation toward one or more concentrating elements which can be mutually similar or different, carrying a heat-transfer fluid, characterized in that the solar collator comprises a means for moving one or more concentrating elements such as to make the collector mobile relative to the mounting of the set of primary mirrors.
