Embodiment Construction

[0026] The following description is provided to enable anyone skilled in the art to make and use the described embodiments and to suggest the best mode contemplated for carrying out some embodiments. However, various modifications will be apparent to those skilled in the art.

[0027] figure 1 is a perspective view of device 100 according to some embodiments. Plant 100 may include a concentrated solar unit. In general, apparatus 100 is operable to receive incident solar radiation, to concentrate the radiation, and to convert the concentrated radiation into electrical current.

[0028] Device 100 includes mirror 110 and mirror 120 . Mirrors 110 and 120 receive radiation from the sun and focus the radiation toward respective localized areas. Mirror 110 and mirror 120 may be of any suitable shape, size, composition, and reflective material known or becoming known, and need not be identical to one another. One or both of mirrors 110 and 120 may be asymmetric about at least on...

Abstract

An apparatus may include a housing having an inner surface and an outer surface, a mirror coupled to the inner surface of the housing, and a receiver unit coupled to the housing. The mirror is to receive direct radiation and to focus the radiation toward a localized area, and the receiver unit is to receive the radiation directly from the mirror and to convert the received radiation to electricalcurrent. Some aspects include a first mirror to receive a portion of direct radiation and to reflect the received portion of direct radiation toward a first localized area, a second mirror to receivea second portion of direct radiation and to reflect the received second portion of direct radiation toward a second localized area, and a receiver unit to receive the reflected portion of direct radiation directly from the first mirror and to convert the received radiation to electrical current. The receiver unit is disposed under the second mirror and is not coupled to a back side of the second mirror.

Description

technical field [0001] Some embodiments relate generally to the conversion of solar radiation into electrical current. More specifically, embodiments may relate to efficient and economical concentration and conversion of sunlight. Background technique [0002] A solar concentrator may receive solar radiation (ie, sunlight) at a first surface area and direct the received radiation to a second, smaller surface area. Therefore, the intensity of solar radiation received in the second area is greater than that received in the first area. This increased strength allows the concentrator to convert received solar radiation into electricity using a smaller solar array than would otherwise be required. [0003] For example, a conventional solar concentrator consists of a parabolic mirror and one or more solar cells arranged at the focal point of the mirror. In operation, the concentrator is positioned such that the one or more solar cells are between the mirror and the sun and the ...
