Modular System for Holographic Solar Concentration Integrated in Urban and Road Elements

Abstract

Holographic concentration solar modules (1), which concentrate the solar light into photovoltaic solar cells (2), integrated into urban and street elements (3), such as street lamps, bus stops, motorway toll booths, charging facilities, advertising sites, kiosks, amongst others, are disclosed. The holographic solar concentration modules (1) carry out passive tracking and the design thereof may be adapted to any surface. The efficient capturing of solar light in any position is guaranteed with the design versatility of the hologram included in the solar module (1). Therefore, in the present invention, in each one of the applications, a constructive element is substituted by a holographic solar concentration module (1). For example, it forms the support of a solar street lamp, the cover of a bus stop or of a toll booth, or the structure of an advertising site, amongst others. The solar module (1) constitutes in this way photovoltaic integration (BIPV) into urban and street elements. The urban and street element can be autonomous or connected to the network, in this last case, wherein it can form part of an intelligent network.

EMBODIMENTS OF THE INVENTION

[0014] In a preferred, but not exclusive, configuration, the invention is applied to supports of solar street lamps, or any other urban or street element, which requires a post. As is observed in FIG. 1, the HSC modules in this case are of the 4.sup.th generation and form a circle. Each row of solar cells is placed vertically and in different orientations of north to south and east to west. Therefore, the electric interconnection of the HSC module can be made with the different rows in parallel. The street lamp can have one or various sections with a diameter variable in height. With an initial diameter of 300 mm and a height of 9 meters, the potential can be sufficiently covered in order to supply LED lights of 100 watts for 10 hours.

[0015] Another non-exclusive configuration relates to substituting the covers of toll booths or bus stops for HSC modules, as can be observed in FIGS. 2 and 3, respectively. In these, the HSC module can be 4th generation and be adapted to the curve of the cover, or 3.sup.rd generation, if it is desired flat. The 5th generation modules can be coupled in covers of toll booths which are sufficiently large. In the case of the 4th and 5th generation modules, the solar collection is increased. The 3.sup.rd generation can be used if it is desired to transmit visible light below the cover. The hologram is designed according to the final form of the urban or street element, such that whatever the orientation thereof, it directs the light towards the solar cell. The interconnections of the solar cells depend in each case on the different orientations which are presented. Rows of cells are connected in series with similar orientation, and in turn, in parallel with rows of cells in different orientations.

[0016] In the case of advertising sites, as is shown in an example in FIG. 4, the HSC modules are adapted to the form of the support, whether it be vertical, horizontal or inclined. The module most adaptable to these types of urban elements, although not exclusive, is the 4.sup.th generation.

[0017] HSC modules can be coupled in practically all types of urban and street elements. Other examples are charging facilities, motorway and road signposts, kiosks, etc.
