Solar panel surface coating method

The invention relates to a surface coating method for a solar panel, in particular to a technology for coating a color point array on a surface of a solar panel to generate a pattern or a character and simultaneously generate electric energy.

In recent years, in order to reduce the environmental pollution caused by petrochemical energy, governments have promoted the use of green energy, including wind energy, hydro energy, geothermal energy, and solar energy. Among them, the use and development of solar energy are several green energy sources. One of the most mature and widely used technologies in development.

At present, the technology of using solar panels to generate electricity is to directly convert solar panels into solar energy for storage or use. Therefore, large solar panels need to be installed in a sufficient sunshine position to achieve the preset power generation efficiency. In the district, if the user wants to install solar panels, most of them can only be installed on the roof of the house or building, and provide solar panel power generation through limited space. However, the power generation efficiency limited by solar panels must be sufficient. Space can provide more power, so how to get enough solar panel space is one of the topics that you want to solve today.

Please refer to FIG. 1 for the location of the conventional advertising plate 101 and FIG. 2 for the conventional solar panel mounting method. When the solar panel area of the building device is rather limited, it is necessary to think about other solar panels that can be installed. Location, and where there are other large-area solar panel mounting positions on the exterior of the building 10, that is, the location of the advertising magazine 101 is set. However, the conventional solar panel 11 has a dark appearance, is monotonous and unattractive, and therefore It is not appropriate to install solar panels 11 on the periphery of the building 10. This will make the building 10 lack of aesthetics and lose the necessary advertising effects or decorations. Therefore, it has not been possible to widely install the solar panels 11 on the periphery of the original building 10 or the advertising version in the past. 10 device location.

Another reason is that in the past, although the manufacturer has made a patterned appearance on the surface of the substrate 12 of the solar panel 11 through the same color difference, the color tone change due to the same color chromatic aberration is too monotonous, and the application is still not suitable for decoration or advertising. Make Use, so the current use of the market as a decorative appearance is very low; please also refer to Figure 3, and the surface of the solar panel 11 if the surface of the solar panel 11 is intentionally painted or pasted to produce a pattern, the color layer 30 is a technique for providing surface color to a color material or a sticker, because the color layer 30 has different sizes of areas A1/A2/A3...the light shielding area of the surface of the solar panel 11 is different, and the color layers 30 have different The spacing distance W1/W2/W3... causes the surface of the solar panel 11 to irregularly penetrate into the light L, thereby causing the substrate 12 of the area of the solar panel 11 in a fixed area unit to be shielded by the area A1/A2/A3 of the color layer 30 and The distance W1/W2/W3 penetrates into the light L is different, so that the internal power generation layer of the fixed area unit has different current output due to the difference in the amount of light L received by each part, and the power generation layer in different parts When different current output amounts are generated, the internal circuit of the substrate 12 is caused to cause severe current interference, so that the solar panel 11 cannot generate electric power output or even be damaged; therefore, the solar panel 11 still has no color on the surface or A technique such as a pattern that produces a visually pleasing effect.

The invention is a surface coating method for a solar panel, characterized in that: the entire surface of the solar panel is coated with an array of color points, the color point array is distributed on the entire surface of the solar panel, and the color point array is distributed through The method produces a different area and a number of color points according to a preset pattern or text, and the color points are evenly distributed.

The secondary feature of the present invention is that the fixed unit area of the solar panel has the same current output source; the color point density of the control color point array can control the solar panel to generate electricity; the color point array has different colors, and Forming a complete pattern or a text effect; the color point array of the color point array is applied by coloring, pasting a sticker or transfer; the color points of the color point array are continuous or connected dots, A square point, strip, or other geometric array.

Referring to FIG. 4 to FIG. 6 , in order to make the surface of the substrate 12 of the solar panel 11 arbitrarily apply color on the surface of the substrate 12 according to the needs of the user, a visual effect or pattern is generated, and Smooth power generation In the present invention, in order to solve the surface coating technique of the substrate 12 of the solar panel 11, the surface coating method of the solar panel of the present invention can solve the problem that the surface of the substrate 12 of the long-term solar panel 11 cannot be patterned or visually lacking.

The main technical point of the surface coating method of the solar panel of the present invention is that the color point array 20 is coated on the surface of the fixed unit area of the solar panel 11, wherein the fixed unit area of the solar panel 11 refers to any specific area in the solar panel 11. The unit of the fixed area has the same current output source as the source, and the fixed unit area can be defined as the whole surface or any partial surface of the solar panel 11. The current output source refers to the conversion of the solar panel 11 after receiving light. The rear output is directed to the source of a particular energy storage device.

In the implementation of the surface coating method of the solar panel 11 of the present invention, the color point array 20 of different areas and color point numbers may be generated according to the calculation of the pattern or text generated by the preset, and the color of the color point array 20 The higher the dot density, the more vivid the color, but the power generation is less controlled due to the lower transmittance of the color point array 20. In other words, the lower the color point density of the color point array 20, the lighter the color, the controllable color. The dot array 20 has a large transmittance and generates a large current. Therefore, the present invention controls the solar panel 11 to generate electric power by controlling the density of the color dots 201 of the color point array 20; the color dots 201 of the color point array 20 may have different colors. Colors, and after the arrangement, form a preset pattern or text effect, wherein the color points 201 of the color point array 20 are applied by coloring or pasting stickers, and the color points 201 may be continuous or The dots, squares, strips or other geometrical arrays of adjacent dots, the color points 201 are evenly distributed on the surface of the solid order area.

Referring to any cross-section of the fixed unit area S of a small area selected in FIG. 6, the area A of each color point 201 is the same, and the uniform color spacings between the color points 201 are evenly distributed to make the light L evenly enter the spacing. The substrate 12 in the solar panel 11 under the W generates electricity to make the panel of the solar panel 11 operate normally. Another feature of the present invention is that the density of the color point 201 formed by the color point array 20 can control the amount of light L entering, thereby controlling the amount of power generation. At the same time, it also produces the pattern or color that needs to be displayed, thereby solving the problem that the solar panel 11 cannot be used as a decoration in the past. The lack of the original can be installed only in the position of the advertising plate without power generation capability, and the solar panel 11 having the power generation effect can be installed, thereby increasing the power generation area of the overall solar panel 11 and having a beautifying effect.

In addition, in the second preferred embodiment of the present invention with reference to FIG. 7 to FIG. 9 , when the color point density coating ratio of the color point array 20 is low, the generated pattern or color vividness is relatively low, and Even if the surface of the solar panel 11 receives a large amount of light L, a large amount of electric energy is generated; please refer to FIG. 9 for any cross-sectional area of a fixed area per unit area S', and the area A of each color point 201 is still Similarly, the density of the color point array 20 is low, so that the color point 201 produces different distributions of the spacings W and W'. However, based on the uniformity of the light transmission, the matching of the spacing W and the spacing W' is uniformly and evenly arranged on the solar panel 11. On the surface.

In summary, the surface coating method of the solar panel of the present invention can display the pattern on the solar panel, so that the decorative area on the periphery of the building which cannot be installed with the solar panel can be used to install the solar panel, thereby increasing the source of electric energy and reaching the green color. The goal of power generation, and the technology of the applied color point array does not cause current interference or control the amount of current generated, but also has a beautifying effect.
