Linearly concentrating solar collector and method for reflector tracking in such a solar collector

Номер: US20130239948A1

Автор: Martin Selig, Max Mertins

Принадлежит: NOVATEC SOLAR GMBH

The basis for the function of a linearly concentrating solar collector lies, in simple terms, in the fact that reflectors reflect incident sunlight onto a receiver tube through which a heat-absorbing medium flows. Owing to the rotation of the Earth, the reflectors need to be adjusted regularly, however, in order to ensure that the sunlight hits the receiver tube. Known tracking methods use calculated positions of the sun for this purpose, which, in the case of structural deviations, for example as a result of expansion and material stress, results in inaccuracies and losses in efficiency. The invention is intended to improve the tracking of the reflectors in such a linearly concentrating solar collector. This is achieved by virtue of the fact that the radiation intensity in the region on both sides next to the receiver tube is measured and, by means of regulation, in the case of uneven emission on both sides of the receiver tube, the reflectors are tracked to such an extent that the radiation intensity on both sides of the receiver is the same and thus the maximum of the radiation intensity is on the receiver tube.

Features for securing tape to annular band

Номер: US20130248666A1

Автор: C. Wayne Clyburn

Принадлежит: Balluff Inc

A tracking band comprises a magnetic tape and mounting tabs that secure the magnetic tape within a band clamp. The mounting tabs protrude radially inwardly toward a center region defined by the band clamp. The magnetic tape is precision-coded with a sequence of magnetic poles. The tracking band may be disposed within an annular recess of a rotating shaft of a heliostat. The tracking band may rotate with the rotating shaft. The shaft may be coupled with a minor such that the minor and rotating shaft rotate concurrently. As the tracking band rotates with the rotating shaft, the tracking band may pass by an encoder head, which may read the magnetic tape and relay information regarding the angular position of the mirror from the magnetic tape to a control system. The tracking band may thus provide altitude and azimuth position information for the mirror to a control system.

A sun-tracking photovoltaic power generation system with a rotating a base having a plurality of photovoltaic power generation panels loaded thereon closely to each other following changes in the solar azimuth angle. A plurality of rails are concentrically laid on an undersurface of the base and wheels are provided to a stand closer to the ground. As a result, it is easier to support the wheels on the same horizontal plane than laying the rails horizontally on a large installation space. Therefore, the construction cost can be reduced and the construction period can be shortened, thereby achieving a large sun-tracking photovoltaic power generation system. Also, because the base is concentrically reinforced by the plurality of rails, the base can be formed by combining, for example, metal L angles, so that a base with a large area can be made light weight at a low cost.

A rigidly mountable solar panel includes lenses supported above a movable panel to focus sunlight onto photovoltaic material carried on the movable panel. Flexible supports space the movable panel at the focal points of the lenses, and a servo-mechanism enables movement of the movable panel to adjust position as the focal point moves with the sun. A light detector on the movable panel, sensing movement of the focal point signals the servo-mechanism to adjust the position of the movable panel automatically, thereby tracking the sun's movement. Concentrating sunlight on photovoltaic material selected to have higher conversion efficiency increases output. Segmenting the photovoltaic material so the output of the segments can be combined in a series-parallel relationship and using mirrors on the ends of the movable panel to reflect sunlight onto the segments allows electricity that is generated by the photovoltaic material to be more uniform during daylight.

A sun-tracking light distributor for a photosynthetic culture in an aqueous liquid, comprising: two light distribution walls made of a transparent material, creating an elongated V-shaped channel adapted to receive the sunlight and to be partly immersed in the aqueous liquid, the sun-tracking light distributor has a center of buoyancy, a vertical passing through the center of buoyancy defines an axis of flotation, and a pivot axis of the sun-tracking light distributor is offset relative to the axis of flotation. Owing to the offset pivot axis, the orientation of the light distributor is changed by varying the level of aqueous liquid, thus allowing a tracking of the sun's altitude.

Described herein are improved solar tracker systems having variable profiles and related operating methods thereof. Solar-tracking PV systems with variable twisted or aerodynamic profiles offer several advantages including improved wind stability, improved shading characteristics and/or capability to correct system component misalignment. In an embodiment, motor drives (and locking devices if present) of a PV system can be driven against each other to cause a desirable twisted or aerodynamic profile of a torque tube and associated PV modules mounted on the torque tube. The desired twisted or aerodynamic profiles can range from a substantially flat horizontal plate to a twisted helix-like profile and combinations thereof so as to establish improved wind and/or shading characteristics. Advantages can also include a reduction in structural materials, increased structural strength, increased solar energy yield or a combination thereof.

A solar energy collection system can include improved mounting hardware for reducing hardware costs and labor required for assembly. For example, mounting hardware can include surfaces for supporting part or all of the weight of a solar module as it is brought into contact with mounting hardware and then moved into a final engaged position. In some systems, a torque tube can include saddle mount assemblies that allow a solar module to be partially engaged and a registered with the saddle mount while being pivoted into a final locked engagement. Some systems can include arrangements sufficient to support the full weight of a solar module in a disengaged position, and as it is moved into a final engaged position. Some systems can include a configuration of apertures and interference or snap-fit features for providing tool-less connections, thereby simplifying the assembly process.

A two-axis tracking solar concentrator system includes a sunlight concentrator, a Fresnel lens, a two-axis solar tracker, sunlight reflectors, an enclosure, a sunlight conversion device, and other components. The lens has very long focal length so that all concentrated sunlight will enter the sunlight conversion device through a small window. The elevation rotation axis goes through the focal point so that the sunlight conversion device will remain at the same horizontal level all the time. The concentrated sunlight makes it easy to achieve a needed temperature. The two-axis tracking design eliminates the need of frequent adjustment. An offset design permits having the sunlight conversion device under shade, so that people do not have to expose themselves to sunlight to do solar cooking. The enclosure significantly reduces the risk of burns and fires. It also makes it very easy to control the heating or cooking process.
