请参考图1-4所示，本发明提供一种双面光伏发电装置，包括：双面光伏发电组件1及反光元件2。双面光伏发电组件1面向太阳光的一面为正面11，另一面为背面12。所述反光元件2设于双面光伏发电组件1的背面12。所述反光元件2具有反光面21以反射太阳光线至双面光伏发电组件1的背面12，该反光面21为面向双面光伏发电组件1的凹面。本发明通过在双面光伏发电组件1的背面12设置反光元件2，利用反光元件2的反光面21反射太阳光至双面光伏发电组件1的背面12从而提高光的利用效率，提高发电效率，进而提高经济效益。
所述双面光伏发电组件1的长度方向定义为X轴，宽度方向定义为Z轴，厚度方向定义为Y轴。图1所示为X轴和Y轴构成的平面。曲线位于X轴和Y轴构成的平面上。所述凹面由曲线在Z轴方向平移得到。垂直于双面光伏发电组件1正面11入射到反光元件2的光线经过凹面反射至双面光伏发电组 件1的背面12，从而可以提高光线的利用率，提高双面光伏发电组件1的发电效率。
所述曲线是抛物线的一段弧线，请参考图1和图2所示，在优选实施例中，曲线的一端位于所述双面光伏发电组件1的一侧边的正下方，也就是曲线的一端为抛物线的顶点，曲线的另一端位于所述双面光伏发电组件1的外侧。照射到双面光伏发电组件1正面11区域之外的光线可以充分利用，全部反射至双面光伏发电组件1的背面12，进行发电。本实施例中，抛物线的顶点定义为X轴和Y轴的零点，则弧线OA代表形成凹面的曲线。图2中，O为坐标轴的零点，A为曲线的另一端的端点，F为抛物线的焦点，B为反光面21在A点反射的光线到达双面光伏发电组件1的背面的位置，反光面21反射的光线全部经过抛物线的焦点F，也就是，A、B连线经过焦点F。图2中，O点的坐标为(0,0)，A点的坐标为(x1,y1),B点坐标为(e,H)，F点坐标为

将方程(3)代入方程(8)，可得：
Figure PCTCN2016105530-appb-000013
上述方程中，e和H是变量，确定e和H后，根据上述方程(7)、(3)和(9)，可得到最优反射效率下曲线的弧长。
在较优的实施例中，反射到双面光伏组件的背面12的光线在X轴方向的范围e满足以下条件：
Figure PCTCN2016105530-appb-000014
其中，L1为双面光伏发电组件1的长度。也就是说经反射后的光线可以照射双面光伏发电组件1的背面12区域的一半及以上，最大可照射双面光伏发电组件1的背面12区域的全部。请参考图1和图2所示，在一实施例中，所述双面光伏发电组件1的X轴方向的两侧均设置所述反光元件2，为了使得双面光伏发电组件1的背面12区域可以充分利用进行发电，控制
Figure PCTCN2016105530-appb-000015
当
Figure PCTCN2016105530-appb-000016
时，光线经过两个反光元件2的反射后可以完全覆盖双面光伏发电组件1的背面12区域；当
Figure PCTCN2016105530-appb-000017
时，光线经过两个反光元件2的反射后不仅可以完全覆盖双面光伏发电组件1的背面12区域，且光线会出现部分重叠，大大提高了双面光伏发电组件1的背面12对光的利用效率。请参考图3和图4所示，在另一实施例中，所述双面光伏发电组件1的X轴方向的一侧设置所述反光元件2，为了使得双面光伏发电组件1的背面12区域可以充分利用进行发电，控制e＝L1，则光线经过反射后可以完全覆盖双面光伏发电组件1的背面12区域，光的利用效率最大。相对于单面光伏组件的发电效率，该双面光伏发电组件1的发电效率提升了100％左右。
在具体实施例中，反光元件2为弧形板，其内凹的表面为反光面21，结构非常简单，容易制作，也容易安装。但不限于此，反光元件2也可以是其他结构，只要其具有面向双面光伏发电组件1凹陷设置的发光面21即可，同样可以将光反射至双面光伏发电组件1的背面。
双面光伏发电组件1的长度根据产品的不同会有多种规格，通常0.5m≤L1≤2m，但不限于此，L1也可以取0.5m～2m范围外的任意值时，通过控制反光元件2的H，即确定了反光元件2的安装位置，并根据方程(7)、(3)和(9)，可得到最优条件下曲线的弧长，使双面光伏发电组件1的发电效率达到最大。
本发明虽然已以较佳实施例公开如上，但其并不是用来限定本发明，任何本领域技术人员在不脱离本发明的精神和范围内，都可以利用上述揭示的 方法和技术内容对本发明技术方案做出可能的变动和修改，因此，凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化及修饰，均属于本发明技术方案的保护范围。
