Description

SOLAR PANEL WITH INTEGRATED ILLUMINATION ARRANGEMENT, AND SYSTEM FOR A SOLAR PANELWITH SUCH AN ARRANGEMENT TECHNICAL FIELD The present invention relates to a solar panel with an integrated illumination arrangement, and to anillumination system comprising a solar panel.
BACKGROUND ART Solar panels are becoming an increasingly important power source and are commonly found in urbanareas, often on roofs but sometimes also on walls of buildings (commonly known as BIPV, or BuildingIntegrated Photovoltaics). ln some cases, entire buildings can be covered in solar panels, makingthem an important part of the visual impression the building gives. ln many cities, buildings are also used to display information such as signs indicating company namesand logos and also to display commercial messages in the form of advertisement, thereby limitingthe wall space where solar panels can be placed. The solar panels themselves can of course beilluminated, sometimes by colored light to create a specific visual effect, but if advertisement orcompany logos or any other non-transparent elements were placed in front of the solar panels theefficiency of the solar panels is believed to decrease dramatically due to a shadowing effect.
DISCLOSURE OF THE lNVENTlON The object of the present invention is to eliminate or at least to minimize the problems describedabove. This is achieved through a solar panel according to the independent claim 1. Thus, by allowinga portion of the front glass of the solar panel to redirect light at an angle to the surface of the frontglass, i.e. parallel to a normal of the front glass, the solar panel can be used to display an image to aviewer. The portion can be of a form corresponding to any graphic element, such as a company logo,a text or an image, and the solar panel can thus act as a sign, information display, advertisement orsimilar. At the same time, the efficiency of the solar panel is lessened only marginally even if theproperties of the portion of the front glass can influence the amount of absorbed light of the solarpanel, compared with other panels not having said portion.
According to an aspect of the invention, the portion of the front glass has a rugged surface. Thereby,in contrast to the general smooth surface of the front glass, the portion can cause a sharp refractionof light out of the front glass, thereby allowing the portion to be clearly visible and display a pattern.
According to another aspect of the invention, the rugged surface of the portion of the front glass ismade by etching. Thereby, even a complicated pattern can be created on the surface of the frontglass with high precision.
According to yet another aspect of the invention, the rugged surface of the portion of the front glassis made by abrasive blasting. Thereby, the pattern can be created without requiring the front glass tobe loosened from the solar panel itself, i.e. after assembly.
According to a further aspect of the invention, the portion of the front glass has a refractive indexthat differs from at least one other portion of the front glass. Thereby, the portion arranged toredirect light can be created in an interior of the front glass and can thus be protected from exposure to wear and tear caused by rain, snow, ice or dirt on the surface of the panel. Furthermore, placingthe portion in the front glass will not cause dirt and particle collection, as is sometimes the casewhen the portion is located on the surface of the front glass and that might cause shadowing of thesolar panel and lower conversion efficiency.
According to yet another aspect of the invention, the light source is a plurality of LEDs or laser LEDsthat are arranged in a frame that runs along at least one side or edge of the solar panel. Thereby, aconvenient and cost effective illumination of the solar panel and the redirecting portion can becreated.
According to a further aspect of the invention, it may further comprise a control unit for controllingpower generated by the solar panel and power supply to the light source and energy storage meansarranged to receive and store energy from the solar panel and also arranged to power the lightsource. Thereby, the solar panel can be arranged to power the light source, by means of the storagemeans, so that the solar panel can function independent of external power supplies.
The invention can be used with all types of solar panels that have a front glass, such as CIGS, CdT, aSi,etc.
Many additional benefits and advantages of the invention will become apparent in view of thedetailed description below.
DRAWINGS The invention will now be described in more detail with reference to the appended drawings, wherein: Fig. 1 shows a side view of a solar panel according to a preferred embodiment of the presentinvention; Fig. 2a shows a cross-sectional view from the side of one embodiment of the solar panel of the solar panel according to Fig. 1; Fig. 2b shows a cross-sectional view from the side of another embodiment of the solar panelof the solar panel according to Fig. 1; Fig. 3 shows a perspective view of a part of the solar panel of Fig. 1; andFig. 4 shows an illumination system with a solar panel according to the invention.DETAILED DESCRIPTION Fig. 1 discloses a side view of an solar panel with integrated illumination arrangement 1 according toa preferred embodiment of the invention, with a solar panel 10 having a substrate 11, solar cells 12formed on said substrate 11 and a translucent front glass 13 covering the solar cells 12 to protectthem from dirt or damage while at the same time allowing sunlight to pass through to the solar cells12. The translucent front glass 13 has a surface 14.
Adjacent to the translucent front glass 13 is a light source 20, in this preferred embodiment in theform of a plurality of LEDs, arranged to emit light into the translucent front glass 13 in a direction with an angle to a normal N of the front glass 13. ln the preferred embodiment, the light source 20 isarranged to emit light into the front glass 13 in a direction essentially perpendicular to the normal N.The light source 20 is mounted in a frame 30 that holds the light source 20 in this position in relationto the solar panel 10 and also prevents leakage, i.e. light emitting directly in a direction parallel to thenormal N beside the front glass. Furthermore, the frame 30 allows for a mounting of the solar panel10 on a surface but it is to be noted that this can be achieved through other types of mountingdevices and that the frame itself is not necessary for the solar panel 1. The LEDs are in oneembodiment mounted in the frame 30, but could also be mounted directly on the edge of the frontglass 13 itself and secured by a profile holding them against the glass or by an adhesive, for example.
Fig. 2a shows the solar panel 10 in a cross-sectional view from the side, with the substrate 11, thesolar cells 12 and the translucent front glass 13. Between the solar cells 12 and the translucent frontglass 13, an adhesive layer 16 may be provided to hold the front glass 13 in place on the solar cells.Also provided in the translucent front glass 13 is a portion 15 that is arranged to redirect at least aportion of the light from the light source in a direction at an angle of less than 90° to the normal N,i.e. out of the front glass in Fig. 2a and 2b. The term redirect is used herein to indicate all phenomenathat serve to alter the propagation direction of light, most notably reflecting and scattering.
The portion 15 thus has altered properties for light propagation, such as refraction and scattering,compared with the rest of the front glass 13, and is in one embodiment shown by Fig. 2a located onthe surface 14. lt can be in the form of a rugged portion or rugged surface, i.e. a portion having asignificantly higher surface roughness compared to the rest of the surface 14. Preferably, surfaceroughness parameter Ra of the portion 15 is 1000-2500 nm or more, and the surface roughnessparameter Ra of the surface 14 is 5.0 nm. The portion 15 can be made by sand blasting or etching apart of the surface 14, for instance.
The surface roughness Ra is an arithmetic average and defined as Ra =å2?:1|y,-|, where yi is a vertical distance from a mean line to the ith data point.
Fig. 2b discloses another embodiment, where the portion 15 of the translucent front glass 13 is aportion having a different refractive index than the rest of the front glass 13. For instance, theportion 15 can have a refractive index of 1,5-1,6, whereas the rest of the front glass has a refractiveindex of 1,46 if sodalime glass is used.
Fig. 3 shows a part of the solar panel 1 in more detail, with a corner of the solar panel 10 having thelight source 20 in the form of arrays of LEDs that are mounted along the sides of the translucent frontglass 13. lt is especially advantageous to provide LED arrays along at least two sides of the solar panel10, and even more advantageous to provide LED arrays along all four sides of the solar panel 10. TheLED arrays 20 are held by frames 30 that serve to support the light source 20, and the LEDs may beprovided with covers 21 that direct the light into the translucent front glass 13.
The operation of the solar panel with integrated illumination arrangement 1 according to theinvention will now be described in more detail with reference to the Figures.
The light source 20, preferably in the form of at least one LED, more preferably in the form of at leastone LED array, is arranged to emit light into the translucent front glass 13 in a direction substantiallyperpendicular to a normal of the front glass 13, i.e. parallel to the surface 14. A portion of this light will propagate through the front glass 13 towards the portion 15, that can for instance be in the formof a rugged surface or a portion having a different refractive index than the rest of the front glass 13.Thanks to the different properties of this portion 15 of the front glass 13, the portion of light isredirected out of the front glass 13 and at least some of the light is redirected in a direction at anangle of less than 90° to the normal N, i.e. perpendicular to the surface 14. The portion 15 ispreferably formed into a pattern that corresponds to an image, a logo or a text, for instance. Theeffect of this is to render the portion 15 of the front glass 13 highly visible to an observer, meaningthe image, logo or text can be seen from a distance. lf the light from the light source is colored, thepattern of the portion 15 will be visible in this color, thus creating an additional visual effect. As analternative to LEDs, other types of light sources can also be used, such as neon lights for instance, orother types of light that are suitable for mounting on a solar panel. The pattern can alternatively beof a simpler shape, such as a rectangle or a circle, for instance, creating a pattern that is easily visibleover large distances and can contribute to creating a larger pattern over an entire building where aplurality of solar panels each display a section of the pattern. Alternatively, the pattern can of courseextend over the entire front glass 13 and thus display the shape of the solar panel itself.
Even though the portion 15 is treated to have the properties mentioned above, for instance by sandblasting or etching, this surprisingly does not significantly lower the efficiency of the solar cells 12present underneath. Rather, the decrease in efficiency, even if the entire surface 14 of the front glass13 is treated to create a rugged surface, is less than 2 percentage units, sometimes even less than 1percentage unit. Thus, for a solar panel with an efficiency of about 15%, the same panel adapted foruse with this invention has been shown to have an efficiency of 14.4% during experiments. Thereby,contrary to what has generally been assumed within the field of solar panels and solar cells, it ispossible to use solar panels as part of an solar panel in accordance with that described herein andstill achieve acceptable or even high efficiency of the solar panels. This renders it possible to use aspace such as the wall of a skyscraper, for instance, both to generate power and to provide an areafor advertisement or decoration to achieve an aesthetically pleasing impression.
The visual effect created by illuminating the portion 15 of the translucent front glass 13 by the lightsource 20 is further increased by providing a plurality of LEDs on at least two sides of the solar panel1. Thereby, the light redirected in a direction at an angle of less than 90° to the normal N has anincreased intensity rendering it visible from a greater distance and allowing the pattern formed bythe portion 15 to show also smaller details.
Fig. 4 shows schematically a system with the solar panel 10 connected to a junction box 120 with acentral processing unit having integrated intelligence that controls the operation of the light source20. The junction box 120 is controlled through a power cable from an inverter 110 that is generallyconnected to a plurality ofjunction boxes controlling light sources for a plurality of solar panels. Theinverter is in turn controlled by a control unit 100 and is also connected to an electric grid 200 fromwhich electric energy is fed to power the inverter, control unit, junction boxes and light sources.Thus, the inverter is set to switch the light of the light sources 20 on and off and to thereby controlthe display on the solar panel 10. Furthermore, the solar module 10 generates energy during the dayand this energy is transmitted via the inverter 110 to the grid 200. Thus, the same cables andconnections are used both for delivering energy to the grid 200 from the solar panel 10 and forreceiving energy from the grid 200 for the light sources 20. ln one embodiment, the system may also include storage means operatively connected to the solarpanel 10 for receiving and storing energy generated by the solar panel 10 and for using this energy topower the light source 20. The operation of the storage means is in this embodiment controlled bythe junction box 120 for each solar panel 10 or by the control unit 100 for the system as a whole. Thestorage means can either be located at each solar panel 10 and serve to power only one panel 10, orbe located in connection with the inverter 110 and serve to receive electrical energy from and feedenergy to a plurality of solar panels 10.
The invention is not to be seen as limited by the embodiments described herein, but can be variedwithin the scope of the appended claims, as will be readily understood by the person skilled in theart.
