如图 1所示，本发明所述太阳能倍光发电装置的优选实施例中包括组合在 同一平面中的多个聚能单元，这些聚能单元可以排成一排或多排，也可以是排 成一列或多列， 本发明优选实施例中为多排多列的阵列组合。  As shown in FIG. 1, a preferred embodiment of the solar power doubling power generation device of the present invention includes a plurality of energy collecting units combined in the same plane, and the energy collecting units may be arranged in one or more rows or in rows. In one or more columns, in a preferred embodiment of the invention, a plurality of rows and columns of array combinations are used.
如图 2所示，本发明所述太阳能倍光发电装置的优选实施例中，每个聚能 单元包括设置在正对太阳光的平板 3上的长条状光伏电池板 1， 在该光伏电池 板 1两侧对称设有两块朝向太阳倾斜的平面反射镜 2, 该平面反射镜在所述光 伏电池板 1宽度方向上的投影长度 s为所述光伏电池板 1的宽度 a的 0. 8-1. 5 倍，优选为 1倍，并调整该平面反射镜 2与所述光伏电池板的夹角 A为 95-115 度， 优选为 106度， 将所述平面反射镜 2固定在同一平板 3的支架 4上。 As shown in FIG. 2, in a preferred embodiment of the solar power doubling power generation device of the present invention, each energy collecting unit comprises a long strip of photovoltaic panel 1 disposed on a flat plate 3 facing the sunlight, at the photovoltaic cell 5 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 1-5 times, preferably 1 time, and adjusting the angle A between the plane mirror 2 and the photovoltaic panel to be 95-115 degrees, preferably 106 degrees, fixing the plane mirror 2 on the same plate 3 on the bracket 4.
如图 3所示，所述平面反射镜 2朝向太阳， 并与所述光伏电池板 1形成夹 角 A ;垂直所述光伏电池板 1的太阳光线 I以入射角 B从平面反射镜 2远离所 述光伏电池板 1的一端的端点 M射入， 经反射后形成反射光线 Γ 照射在该光 伏电池板 1上。所述夹角 A越大时， 入射角 B越大， 则由 M点入射的太阳光线 I经平面反射镜 2反射后的光线 Γ 越远离所述光伏电池板 1。调整该夹角 A， 可以使反射光线 Γ 不超过光伏电池板离该平面反射镜较远的端点 N， 此时， 照射到该平面反射镜 2上的所有太阳光线， 即 K区域的太阳光线， 经反射后均 能投射到所述光伏电池板 1，使该光伏电池板 1获得 1倍太阳光照强度。同样， 另一块平面反射镜也是如此。 由于设置投影长度为该光伏电池板 1的 1倍，所 以光伏电池板 1接收到 3倍太阳光照强度。所有光伏电池板 1的光导作用产生 电流通过导线并联接到集电装置， 产生可用的电能。  As shown in FIG. 3, the plane mirror 2 faces the sun and forms an angle A with the photovoltaic panel 1; the solar ray I perpendicular to the photovoltaic panel 1 is away from the plane mirror 2 at an incident angle B. The end point M of one end of the photovoltaic panel 1 is incident, and after reflection, forms a reflected ray, which is irradiated onto the photovoltaic panel 1. When the angle A is larger, the incident angle B is larger, and the light rays reflected by the solar ray I incident from the M point are reflected away from the photovoltaic panel 1 by the plane mirror 2. Adjusting the angle A so that the reflected light Γ does not exceed the end point N of the photovoltaic panel that is far from the plane mirror. At this time, all the sunlight rays on the plane mirror 2, that is, the sun rays in the K region, are irradiated. After being reflected, it can be projected onto the photovoltaic panel 1 so that the photovoltaic panel 1 obtains 1 time of solar light intensity. Again, the same is true for another flat mirror. Since the projection length is set to be 1 times that of the photovoltaic panel 1, the photovoltaic panel 1 receives 3 times the sunlight intensity. The photoconducting action of all photovoltaic panels 1 produces a current through the conductors connected in parallel to the collector to produce the available electrical energy.
