上述瓦片1具有沿其厚度方向相对设置的第一侧面和第二侧面，第一侧面上设有嵌设槽11，太阳能电池组件2嵌设于嵌设槽11内。嵌设槽11的至少一个侧壁与第一侧面相接的位置设有拆卸孔12，拆卸孔12设置为使太阳能电池组件2脱离嵌设槽11。
本实施例中，嵌设槽11具有依次连接的第一侧壁、第二侧壁和第三侧壁，其中，第一侧壁和第三侧壁平行设置，第一侧壁和第二侧壁垂直设置。在第二侧壁和第一侧面相接的位置设置拆卸孔12，在拆卸太阳能电池组件2时，将手指或拆卸工具插入拆卸孔12内，通过向第一侧面所在侧拨动太阳能电池组件2的方式，使太阳能电池组件2的一端脱离嵌设槽11，再手动将太阳能电池组件2拿出嵌设槽11即可。
于其他实施例中，还可以在瓦片1上设置沿太阳能电池组件2厚度方向延伸的拆卸孔12，并使拆卸孔12贯穿嵌设槽11的其中一个侧壁和与该侧壁平行设置的瓦片1的外壁。在拆卸太阳能电池组件2时，将手指或柱状的拆卸工具等从瓦片1的外壁插入拆卸孔12内，并抵接于太阳能电池组件2，通过向第一侧面所在侧拨动太阳能电池组件2的方式，使太阳能电池组件2的一端脱离嵌设槽11，再 手动将太阳能电池组件2拿出嵌设槽11即可。
本实施例在瓦片1上开设嵌设槽11，将太阳能电池组件2嵌设于嵌设槽11内，安装方式简单，实现太阳能电池组件2和瓦片1的集成设置，在搭建屋顶时即可将该太阳能瓦片1直接安装在屋顶上，无需单独设置将太阳能电池组件2安装在瓦片1上的安装支架，结构简单，成本低。
本实施例在嵌设槽11的至少一个侧壁和第一侧面相接的位置设置拆卸孔12，利用拆卸工具或手指等一端插入拆卸孔12内并作用于太阳能电池组件2，使太阳能电池组件2脱离嵌设槽11，拆卸方便快捷，便于更换太阳能电池组件2，降低了维修难度；而且无需在瓦片1上设置通孔，可以有效避免屋顶漏水。
本实施例中，安装孔13设于第一侧面上未设置嵌设槽11的区域，以避免太阳能电池组件2对瓦片1和瓦条5之间的连接造成干涉。
可选的，瓦片1上设有凸起14和凹槽15，凸起14设置为和与其相邻的瓦片1上的凹槽15插接，凹槽15设置为和与其相邻的瓦片1上的凸起14插接。示例性的，凹槽15和凸起14中的其中一个设于瓦片1的第一侧面，另一个设于第二侧面。
在实际搭建屋顶的过程中需要用到多个瓦片1，通常相邻两个瓦片1之间采用搭接的方式，并利用凸起14和凹槽15插接的方式提高相邻两个瓦片1之间连接的稳定性；同时相邻两个太阳能电池组件2之间无缝拼接，可以有效防止屋顶漏水。
示例性的，太阳能电池组件2包括由第一侧面至第二侧面方向依次层叠设置的透明玻璃23、电池片组24和背板25，电池片组24厚度方向的两侧面分别与透明玻璃23和背板25采用乙烯-醋酸乙烯共聚物粘贴连接，在透明玻璃23和电池片组24之间的乙烯-醋酸乙烯共聚物形成第一封装层，在电池片组24和背板25之间的乙烯-醋酸乙烯共聚物形成第二封装层。在实际形成太阳能电池组件2的过程中，将透明玻璃23、第一封装层、电池片组24、第二封装层和背板25依次层叠设置，之后再采用层压工艺形成太阳能电池组件2。
其中，背板25为聚偏二氟乙烯膜-耐高温聚酯薄膜-氟皮膜复合板(以下称为KPF板)，即背板25包括依次层叠设置的聚偏二氟乙烯膜([Poly(vinylidene fluoride)]，PVDF)、耐高温聚酯薄膜(Polyethylene terephthalate，PET)和氟皮膜，在安装时使氟皮膜面朝太阳能电池组件2设置。本实施例中，如图5所示，背板25面朝电池片组24的一侧形成有第一黑色镀层251，能降低眩光污染，提高太阳能瓦片结构的美观效果。
本实施例中，背板25背对太阳能电池组件2的一侧可以设置白色镀膜，也可以不做任何处理。上述两种方式，能够在保证整个太阳能瓦片结构美观性能的同时，提高了太阳能电池组件2的散热效果。于其他实施例中，还可以在背板25背对太阳能电池组件2的一侧也设置第一黑色镀层251，但会降低太阳能电池组件2的散热效果。
可选的，上述电池片组24包括多个依次排列的电池串20，多个电池串20采用汇流条并联。电池片组24面朝透明玻璃23的一侧设有遮黑条3，遮黑条3设于电池片组24长度方向的两端，遮黑条3至少面朝透明玻璃23的一侧形成有第二黑色镀层31。
本实施例中，遮黑条3为氟皮膜-耐高温聚酯薄膜-氟皮膜复合板(以下称为FPF板)，即遮黑条3包括依次层叠设置的氟皮膜、PET膜和氟皮膜。通过对遮黑条3面朝透明玻璃23的一侧形成的第二黑色镀层31，能够更好地减少眩光污染。本实施例对遮黑条3上除面朝透明玻璃23的侧面外的其他侧面是否镀膜不做要求。
本实施例中，背板25设置为KPF板，遮黑条3设置为FPF板。在一实施例中，背板25为KPF板时，遮黑条3可以不设置成FPF板；遮黑条3为FPF板时，背板25可以不设置为KPF板。
通常背板25的厚度大于290μm±30μm，为了减少遮黑条3和背板25之间的色差，本实施例中，遮黑条3的厚度为133μm±30μm，遮黑条3的厚度太薄，会导致遮黑条3和背板25之间存在严重的色差，遮黑条3的厚度太厚，则会导致太阳能电池组件2存在较多的工艺制程问题，而且遮黑条3内部可能会存在气泡。
本实施例中，透明玻璃23选择低铁钢化压花玻璃，以应对多种复杂的天气，对电池片组24进行有效的保护。可选的，透明玻璃23背对电池片组24的一侧设置双层镀膜，例如，如图6所示，透明玻璃23背对电池片组24的一侧形成有依次层叠设置的第一透明镀膜231和第二透明镀膜232，第一透明镀膜231的厚度为85μm-100μm，第二透明镀膜232的厚度为75μm-90μm。通过对透明玻璃23进行镀膜，以提升太阳能电池组件2的功率。
本实施例中，第一透明镀膜231的厚度为85μm-100μm，第二透明镀膜232的厚度为75μm-90μm。在一实施例中，第一透明镀膜231的厚度为85μm-100μm时，第二透明镀膜232的厚度可以不设置为75μm-90μm；第二透明镀膜232的厚度为75μm-90μm时，第一透明镀膜231的厚度可以不设置为85μm-100μm。
于其他实施例中，也可以不对透明玻璃23进行镀膜，以避免透明玻璃23上的镀膜被划伤，以及降低太阳能电池组件2中多个部件之间的色差，提高太阳能电池组件2的外观效果。
每个电池串20包括多个依次串联的电池片201，由于不同型号的电池片201的颜色不同，为了使整个太阳能电池组件2的颜色一致，提高美观效果，本实施例中，尽量选择深颜色的电池片201，如可以选择电池片专业领域划分上的D色电池片和D1色电池片。
示例性的，如图2和图3所示，电池片组24具有正极线缆21和负极线缆22，正极线缆21和负极线缆22位于电池片组24长度方向的同一端，方便相邻两个太阳能瓦片结构之间的接线。本实施例中，背板25背离电池片组24的一侧设有与电池片组24电连接的接线盒4，接线盒4电连接于上述正极线缆21和负极线缆22。为了便于接线盒4的安装，本实施例中，在瓦片1上正对接线盒4的位置设置有装配孔16。
其中，每个电池串20包括相邻设置的两排电池片201，将同一排电池片201的正负极分布相同，同一电池串20的两排电池片201的正负极分布相反，从而将两排电池片201串联形成一个电池串20，将电池串20的正负极连接于接线盒4，再将接线盒4的正负极分别连接于正极线缆21和负极线缆22。
本申请提供的太阳能瓦片结构，在瓦片1上开设嵌设槽11，将太阳能电池组件2嵌设于嵌设槽11内，安装方式简单，实现太阳能电池组件2和瓦片1的集成设置，在搭建屋顶时即可将该太阳能瓦片直接安装在屋顶上，无需单独设置将太阳能电池组件2安装在瓦片1上的安装支架，结构简单，成本低。本申请中，瓦片1上设置拆卸孔12，利用拆卸工具或手指等的一端插入拆卸孔12内并作用于太阳能电池组件2，即可使太阳能电池组件2脱离嵌设槽11，拆卸方便快捷，便于更换太阳能电池组件2，降低了维修难度。
