具体实施方式detailed description
下面结合附图对本发明进行详细描述，所做的描述是为了帮助本领域的技术人员更好地理解本发明，不是对本发明的保护范围的限制。The present invention is described in detail below with reference to the accompanying drawings, which are intended to be understood by those skilled in the art.
图1示出了依据本发明的一种实施方式的太阳能发电系统装置 的结构的示意性剖视图。如图1所示，在太阳能电池板1的旁边安装至少一块漫反射板2。尽管图中仅示出了一块漫反射板，但是本领域技术人员应该意识到，该漫反射板可以有多块。1 shows a solar power generation system device in accordance with an embodiment of the present invention. A schematic cross-sectional view of the structure. As shown in FIG. 1, at least one diffuse reflection plate 2 is installed beside the solar cell panel 1. Although only one diffuse reflector is shown in the figures, those skilled in the art will appreciate that the diffuse reflector can have multiple pieces.
根据一种实施方式，所述漫反射板2为一块，该漫反射板2可以绕所述太阳能电池板1移动，从而反射最多的阳光给太阳能电池板1。例如使得漫反射板2一直朝向太阳。另外，该漫反射板2相对于太阳能电池板1的倾角随太阳的移动而改变。根据一种实施方式，保持所述漫反射板2在设定时间段相对于太阳能电池板的角度在90-145度之间。即便漫反射板相对于太阳能电池板1的倾角随太阳的移动而改变，也保持所述漫反射板2在设定时间段相对于太阳能电池组件的角度在90-145度之间，如果超过这一角度，则不必要求漫反射板尽可能垂直阳光入射方向。According to an embodiment, the diffuse reflection plate 2 is a piece, and the diffuse reflection plate 2 is movable around the solar cell panel 1 to reflect the most sunlight to the solar cell panel 1. For example, the diffuse reflection plate 2 is always facing the sun. In addition, the inclination angle of the diffuse reflection plate 2 with respect to the solar cell panel 1 changes with the movement of the sun. According to an embodiment, the angle of the diffuse reflector 2 relative to the solar panel is maintained between 90-145 degrees for a set period of time. Even if the inclination angle of the diffuse reflection plate with respect to the solar cell panel 1 changes with the movement of the sun, the angle of the diffuse reflection plate 2 with respect to the solar cell module is maintained between 90 and 145 degrees for a set period of time, if this is exceeded At one angle, it is not necessary to require the diffuse reflector to be as perpendicular to the direction of sunlight as possible.
实验表明，采用漫反射的方式，反射的光线比较平均，利于太阳能电池组的设计，而且在太阳能电池板1的四周设有漫反射板2的情况下，发电的效果与设置镜面反射板的情况并无实质性的不同，甚至采用漫反射板的情况还要好一些。这与之前的本领域的知识不同。虽然不清楚其原因，但是发明人推测可能有两个原因，一方面是集中的镜面反射的光，由于不均匀，并不会被目前的太阳能电池板完全转化成电能，其次是光入射的情况实际上比较复杂，镜面反射板所反射出去不被太阳能电池板1接收到的光并不一定比被漫反射板所发射出去的光少。Experiments show that the diffuse reflection method is more average for the reflected light, which is beneficial to the design of the solar cell stack, and the effect of generating electricity and the setting of the specular reflector when the diffuse reflector 2 is provided around the solar panel 1. There is no substantial difference, even with diffuse reflectors. This is different from previous knowledge in the field. Although the reason is not clear, the inventors speculate that there may be two reasons. On the one hand, the concentrated specular reflection light is not completely converted into electric energy by the current solar panel due to unevenness, and secondly, the light is incident. In fact, it is more complicated, and the light reflected by the specular reflector not received by the solar panel 1 is not necessarily less than the light emitted by the diffuse reflector.
下表列出了在内蒙古赤峰市巴林左旗的晴天所做实验的情况。 The table below shows the results of experiments conducted on sunny days in Bahrain Zuoqi, Chifeng City, Inner Mongolia.
在该实验中采用了上海海润电池板。试验时分成三组，第一组在方形的电池板周边设置4面平面镜(镜面反射组)，第一组在相同方形的电池板周边设置4面漫反射板(漫反射组)，第三组在相同方形的电池板周边未设置任何反射物(无反射组)。Shanghai Hairun battery panels were used in this experiment. The test is divided into three groups. The first group is provided with four plane mirrors (specular reflection group) around the square panel. The first group is provided with four diffuse reflectors (diffuse reflection group) around the same square panel. The third group No reflectors (no reflection groups) were placed around the perimeter of the same square panel.

在设有两个漫反射板和1个漫反射板的情况下的实验也同样表明，使用漫反射板与使用镜面反射板在提高发电量方面并无实质性的差别，采用漫反射板的情况稍微高一点点。Experiments with two diffuse reflectors and one diffuse reflector also show that there is no substantial difference in the use of diffuse reflectors and the use of specular reflectors to increase power generation. Slightly higher.
图2示出了依据本发明的另一种实施方式的太阳能发电系统装置的结构的示意性剖视图。如图2所示，依据本实施方式的装置的结构与图1的结构的不同之处在于，该装置在漫反射板2上设置有多个孔3。增加孔3能够增加漫反射板的使用寿命。孔3可以根据使用地区的环境情况设置，根据一种实施方式，孔3在漫反射板上均匀设置，孔径大小也可相同或略有差异。根据另一种实施方式，漫反射板靠近地面的一侧的孔的面积比远离地面的一侧的孔的面积大。在一种情况下，大1.25倍到1.75倍。另外，远离地面的一侧的孔的密度比靠近地面的一侧的孔的密度大。在一种实施方式中，远离地面的一侧的孔的密度与靠近地面的一侧的孔的密度之间的关系为：2 is a schematic cross-sectional view showing the structure of a solar power generation system apparatus according to another embodiment of the present invention. As shown in FIG. 2, the structure of the apparatus according to the present embodiment is different from the structure of FIG. 1 in that the apparatus is provided with a plurality of holes 3 in the diffuse reflection plate 2. Increasing the hole 3 can increase the service life of the diffuse plate. The holes 3 may be arranged according to the environmental conditions of the area of use. According to one embodiment, the holes 3 are evenly arranged on the diffuse reflection plate, and the aperture sizes may be the same or slightly different. According to another embodiment, the area of the hole on one side of the diffuse reflection plate near the ground is larger than the area of the hole on the side far from the ground. In one case, it is 1.25 times to 1.75 times larger. In addition, the density of the hole on the side far from the ground is larger than the density of the hole on the side close to the ground. In one embodiment, the relationship between the density of the holes on one side away from the ground and the density of the holes on the side near the ground is:
远离地面的一侧的孔的密度＝靠近地面一侧的孔密度*靠近地面 一侧的单个孔的面积/远离地面一侧的单个孔的面积*(1+cos(漫反射板的长度*漫反射板相对地面的倾角))*地区系数。Density of the hole on the side far from the ground = hole density on the side near the ground * near the ground Area of a single hole on one side / Area of a single hole on the side away from the ground* (1+cos (length of diffuse reflector * inclination of diffuse reflector relative to the ground)) * Area factor.
地区系数可以通过实验获得。The regional coefficient can be obtained experimentally.
图3示出了依据本发明的又一种实施方式的太阳能发电系统装置的结构的示意性剖视图。3 is a schematic cross-sectional view showing the structure of a solar power generation system apparatus according to still another embodiment of the present invention.
在图1和图2所示的实施方式中，漫反射板2均为直板。在漫反射板为锥形时，其截面亦为直线型，而依据图3所示的实施方式，漫反射板2的至少一部分为曲面的形状，带有弧度。根据一种实施方式，所述曲面的圆心在所述曲面的远离太阳能电池板的方向。漫反射板的不同部分的曲面的弧度可以不同。采用有弧度的设计用以增加漫反射光在电池板上的覆盖面积，从而可以使用相对较矮的反射板增加相对较大面积的太阳能电池板的发电量。In the embodiment shown in Figures 1 and 2, the diffuse reflectors 2 are all straight plates. When the diffuse reflection plate is tapered, the cross section thereof is also linear, and according to the embodiment shown in Fig. 3, at least a part of the diffuse reflection plate 2 has a curved shape with a curvature. According to an embodiment, the center of the curved surface is in a direction away from the solar panel of the curved surface. The curvature of the surface of different parts of the diffuse reflector can vary. The curved design is used to increase the coverage area of the diffusely reflected light on the panel, so that a relatively short reflector can be used to increase the power generation of a relatively large area of the solar panel.
另外，本领域技术人员容易理解，在图3所示的实施方式中，也可以如图2所示的实施方式一样包括孔3。孔3的大小和分布可以如以上针对图2所做的描述那样。 In addition, those skilled in the art will readily appreciate that in the embodiment illustrated in FIG. 3, the apertures 3 may also be included as in the embodiment illustrated in FIG. 2. The size and distribution of the holes 3 can be as described above for Figure 2.
