The present invention relates to a solar panel system, particularly a novel solar panel design to increase performance in a cost-effective manner.
Solar panel technology has evolved over the last several decades. Solar panels typically include a flat sheet of semiconductor material which absorbs the sun's rays and converts the sun's light and heat to electrical energy. However, conventional solar panels composed of flat sheets are subjected to wind forces that may impact the structural integrity of the panels on a windy day or during a storm. Mounting systems for solar panels exists but are rather expensive to manufacture and install.
Therefore, a need exists for solar panels that are cost effective and structurally configured to withstand wind forces, as well as being easy to install. The present invention addresses this need.
The present invention relates to a solar panel system, particularly a novel solar panel design to increase performance in a cost-effective manner. The present invention discloses an elongated solar electric module which includes a first transparent material and a second transparent material. A solar electric material may be disposed between the first transparent material and the second transparent material.
The present invention also discloses a solar panel assembly which includes a plurality of elongated solar electric tubes. Each of the elongated solar electric tubes has two or more adjacent planes. Additionally, the solar panel assembly includes a solar electric material comprising one or more arrays of solar electric cells spaced apart and coupled electrically. The solar electric material spans the two or more adjacent planes on inside portions of each elongated solar electric tube.

The present invention relates to a solar panel system, particularly a novel solar panel design to increase performance in a cost-effective manner. The present invention discloses an elongated solar electric module which includes a first transparent material and a second transparent material. The elongated solar electric module also includes a solar electric material disposed between the first transparent material and the second transparent material.
The solar panel system disclosed in the present invention is cost-effective as the material components of the solar electric module are readily abundant-transparent materials, solar cells, adhesives, and other commoditized materials. Furthermore, the present disclosure provides several embodiments of solar electric modules of lesser weight than conventional solar electric modules thereby facilitating easier installation.
In some implementations, the solar panel systems disclosed herein employs bi-facial solar cells to catch light directly from the sun and also light reflected from a surface (e.g., of a roof directly under the solar panel systems.
A solar panel consistent with the present invention may include an elongated array of one or more solar electric modules. Likewise, each solar electric module may include an elongated array of solar electric cells spaced apart but coupled to each other electrically. In some implementations, each array of solar electric cells include bi-facial photovoltaic materials (e.g., solar cell).
Although
In some embodiments, each solar electric module is spaced apart a distance that is at least one quarter the width of each elongated solar electric module. Further, the cross section of each solar electric module may be a square shape, triangular shape, elliptical shape, or circular shape. It should be known, however, that the present invention is not limited to these shapes but are representative and exemplary of embodiments of the present invention.
Solar electric module 100 absorbs solar light and converts said absorbed light into electrical energy. The converted electrical energy may be routed from the solar electric module 100 device. In the embodiment shown, the shape of first and second transparent materials 107, 108 are intended to cause more sunlight to reach the solar electric material 102.
First and second transparent material 107, 108 may have a cross-sectional thickness in the range of 5-15 mm. For example, in one embodiment, the cross-sectional thickness of each transparent material 107, 108 is approximately 10 mm.
Between first and second transparent material 107, 108 lies a solar electric material. In various embodiments throughout this disclosure, solar electric material 102 is a photovoltaic material 102. For example, photovoltaic material 102 may comprise monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, or copper indium gallium selenide/sulfide. Photovoltaic material 102 absorbs incident solar light and converts the light energy into electrical energy.
In one or more embodiments of the present invention, photovoltaic material 102 is embedded in adhesive material layer 103. As shown in the figure, the top surface 105 of adhesive material 103 is incident to the bottom surface of first transparent material 107. Furthermore, the bottom surface 106 of adhesive material 103 is incident to the top surface of second transparent material 108.
In this disclosure, the materials (e.g., photovoltaic material 102 and adhesive material 103) between first transparent material 107 and second transparent material 108 may be collectively referred to as a stack 1 of materials.
Stack 211 includes a photovoltaic material 202 disposed between adhesive materials 203a, 203b. Stack 21 also includes lateral material layers 204a, 204b on the sides of photovoltaic material 202 and adhesive materials 203a, 203b. Lateral material layers 204a, 204b may be electrically resistive to electrically isolate photovoltaic material 202 within the solar electric module 200. Lateral material layers 204a, 204b may comprise silicone, butyl rubber, or any other suitable material known in the art.
In some embodiments, the top surface 205 of adhesive material layer 203a is incident to first transparent material 207 whereas the bottom surface 206 of adhesive material layer 2036 is incident to second transparent material 208. In some embodiments, lateral material layers 204a, 2046 may have adhesive properties as well.
Notably, the area of first transparent material 207 is less than the area of second transparent material 208. As shown, the cross-sectional thickness 209 of first transparent material 207 is less than the cross-sectional thickness 210 of second transparent material 208. In some embodiments, cross-sectional thicknesses 209, 210 of the first and second transparent materials 207, 208, respectfully, may range from 5-15 mm. For example, cross-sectional thickness 209 of first transparent material 207 may be 8 mm whereas the cross-sectional thickness 210 of second transparent material 208 may be approximately 10 mm.
In the figure, first transparent material 301 has a triangular shape whereas second transparent material 302 has a semi-circular shape. The different shapes of transparent materials 301, 302 effect various performance attributes and may enable easier or cheaper device manufacturing.
Each transparent material 301, 302 may have an effect on the solar electric material. For example, the round shape of second transparent material 302 may allow wind to flow smoothly there beneath. Accordingly, the overall shape of solar electric module 300 may be aerodynamically suited to provide a stable apparatus that is resistant to wind forces.
Notably, solar electric module 400 includes disjointed, photovoltaic materials 402a, 402b to facilitate the bend in the first and second transparent materials 401, 405. In the embodiment, the photovoltaic materials 402a, 402b are enmeshed within adhesive material 403. In the embodiment shown, first and second transparent materials 401, 405 each have a bent portion in a central region therein.
Notably, second transparent material 502 has a quadrilateral shape with a hollow portion 512. Hollow portion 512 may provide many benefits to solar electric module 50 and therefore the solar panel which contains these modules.
For example, hollow portion 512 facilitates a cost-effective solar electric module as it may require fewer kilograms of glass than conventional solar electric modules. Therefore, solar panels which incorporate solar electric modules 50 are easier to install as they are lesser in weight. Moreover, the configuration of solar electric module 50 may yield a much stronger assembly than solar electric modules made of conventional planar glass sheets (transparent materials).
Notably, first transparent material 601 is similar to the first transparent material in the previous figure. However, second transparent material 602 is shaped such that a first half is triangular but the bottom half is semi-circular. The hollow portion 512 may also yield a stronger assembly than a solar electric module comprising planar transparent sheets.
Stack 814 includes adhesive material 803, solar electric materials (e.g., photovoltaic material layers) 802a, 802b, and material layer 813. In some embodiments, photovoltaic material layers 802a, 802b are bi-facial.
The photovoltaic material layers 802a, 802b may be adhered to the transparent material 801 by an adhesive material 803. In some implementations, adhesive material 803 is disposed between an inside portion of transparent material 801 and photovoltaic material layers 802a, 802b. On opposing sides of each photovoltaic material layer 802a, 802b is a material layer 813.
In some embodiments, material layer 813 comprises one or more transparent materials which are designed to reduce the reflection of light that enter the lower side of the photovoltaic material. In some implementations, material layer 813 includes an anti-reflective material.
Material layer 813 may comprise silicone or ethyl vinyl acetate but the present invention is not limited thereto. In some implementations, material layer 813 may be relatively weak mechanically and may have optical properties which allow light to effectively reach the bi-facial solar cells 802a, 802b. Notably, the solar electric module 801 functions well to collect and convert sunlight into electrical energy although the bottom side of solar electric materials 802a, 802b are not adjacent to a transparent material (e.g., the bottom half portion of transparent material 801).
Adhesive material 803 may have a thickness below one millimeter. Material layer 813 may comprise any composition such that when reflected light rays are incident thereto, material layer 813 facilitates their transmission to the photovoltaic material layers 802a, 802b. Transparent material 801 has a hollow portion 812 therein.
In some implementations, material layer 913 may be relatively weak mechanically and may have optical properties which allow light to effectively reach the bi-facial solar cells 902a, 902b. Notably, the solar electric module 901 functions well to collect and convert sunlight into electrical energy although the bottom side of solar electric materials 902a, 902b are not adjacent to a transparent material (e.g., the bottom half portion of transparent material 901).
In addition, solar electric module 10 includes a hollow portion 1012 therein. Adhesive material 1003 may have a thickness below one millimeter. In some implementations, material layer 1013 includes an anti-reflective material.
As shown, the variation in thickness is noted by section 1010 at the bottom of transparent material 1001. Notably, below the hollow portion 1012 near one end of the transparent material 1001 is a thicker portion 1011 of transparent material 1001.
The thicker portion 1011 of transparent material 1001 may increase the amount of reflected light that reaches the photovoltaic material layers 1003a, 1003b as the index of refraction of the transparent material 1001 causes the reflected light to bend inside of the transparent material 1001 preferably towards the photovoltaic material layers 1003a, 1003b.
In some implementations, material layer 1013 may be relatively weak mechanically and may have optical properties which allow light to effectively reach the bi-facial solar cells 1002a, 1002b. Notably, the solar electric module 101 functions well to collect and convert sunlight into electrical energy although the bottom side of solar electric materials 1002a, 1002b are not adjacent to a transparent material (e.g., the bottom half portion of transparent material 1001).
In some embodiments, material layer 1011 comprises a transparent material which may be formed by solidifying a liquid transparent material at one end of the transparent material 1001 (below the hollow portion). Advantageously, material layer 1010 may increase the amount of reflected light that reaches the photovoltaic material layers 1002a, 1002b as the index of refraction of the transparent material (e.g., >1) causes the reflected light to bend inside of the transparent material 1001 preferably towards the photovoltaic material layers 1002a, 1002b. In some embodiments, material layer 1011 has the same index of refraction as transparent material 1001.
Solar electric materials 1102a, 1102b may adhere to an inside wall of the transparent material 1101 via regions of adhesive material 1103. Further, material layer 1113 may be disposed on a backside of the solar electric materials 1102a, 1102b according to choice and design. In some implementations, material layer 1113 includes an anti-reflective material.
Notably, the cross-section of solar electric modules 1201 is consistent with the solar electric modules in
