具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本发明公开的实施例为解决现有技术中光伏发电单元容易局部开胶、易变形的技术问题，提供一种光伏组件、光伏系统、屋面板及交通工具。
本公开实施例提供一种光伏组件，如图1-3所示，包括光伏发电单元10和与光伏发电单元10的非光电转换面连接、且用于支撑光伏发电单元10的支撑部件20，光伏发电单元10的非光电转换面与支撑部件20热合连接。
此处，光伏发电单元10的非光电转换面与支撑部件20热合连接，是光伏发电单元10的非光电转换面与支撑部件20通过热熔层压结合在一起，使支撑部件20与光伏发电单元10融为不可分割的整体。
示例的，在0.5～1个大气压、100～200℃的条件下，对光伏发电单元10和支撑部件20热熔层压20～40分钟。
例如，当支撑部件20为金属材质时，在1个大气压、160℃的条件下，对光伏发电单元10和支撑部件20热熔层压30分钟。
可选的，支撑部件20包括承载部21，光伏发电单元10具体与承载部21热合连接。
需要说明的是，第一，如图1所示，当支撑部件20仅包括承载部21时，支撑部件20可以全部热合连接于光伏发电单元10上；如图2和图3所示，支撑部件20也可以部分热合连接于光伏发电单元10上，只要光伏发电单元10与支撑部件20可成为一不可分割的整体即可。
第二，不对支撑部件20的材料进行限定，只要支撑部件20可与光伏组件10热合连接为一个整体，且支撑部件20不会在热合过程中融化即可。
具体的，支撑部件20可以是金属材质。金属材质的支撑部件20不但不会在高温情况下融化，还具有防雷效果，且相同体积的材料，金属的重量比较大，可防止在强风天气，与支撑部件20热合连接的光伏发电单元10被强风吹变形。
第三，本公开实施例提出的光伏发电单元10可以是柔性光伏发电单元，也可以是晶硅光伏发电单元，柔性光伏发电单元的材料例如可以包括铜铟镓硒，晶硅光伏发电单元的材料例如可以是单晶硅或多晶硅。
其中，柔性光伏发电单元具有柔韧性好、轻薄、弱光性好、颜色可调、形状可塑性等优点，可提高光伏发电单元10的适应性及实用性。
第四，本领域的技术人员应该知道，光伏发电单元10的光电转 换面是指：光伏发电单元10中在接受光照时可进行光电转换的一面。光伏发电单元10中与光电转换面相对(相反)的面即为非光电转换面。
本公开实施例提供一种光伏组件，包括光伏发电单元10和与光伏发电单元10的非光电转换面热合连接的支撑部件20，相较于采用背胶粘接，本公开实施例采用热合连接的方式，可以使光伏发电单元10与支撑部件20连接的更加牢固，这样一来，即使遇到强风天气，光伏发电单元10也会固定在支撑部件20上，不会发生变形；并且，由于光伏发电单元10的面积通常较大，若采用背胶粘接，则需耗费非常多的背胶，不利于节省制备成本，因此，相较于采用背胶粘接，采用热合连接的方式，可减少制备光伏组件的制备成本。
在此基础上，由于光伏发电单元10和支撑部件20成为一个不可分割的整体，可增加光伏组件10和支撑部件20的整体重量，这样一来，即使遇到强风天气，强风也不易使光伏发电单元10和支撑部件20移动，从而可避免不必要的人员伤亡和经济损失。
可选的，如图2和图3所示，支撑部件20还包括固定部22，固定部22与承载部21连接于同一平面内、且超出光伏发电单元10的边缘。换言之，固定部22与承载部21相连接并与承载部21处于同一平面内，并且固定部22超出光伏发电单元10的边缘。
此处，固定部22与承载部21可以是一体成型结构。
需要说明的是，固定部22可以超出光伏发电单元10的一个、或两个、或三个、或四个边缘。
本公开实施例中，由于固定部22超出光伏发电单元10的边缘，因此，在将光伏组件固定在安装载体上时，可避免对光伏发电单元10造成损坏。
进一步可选的，如图4所示，光伏组件还包括与固定部22固定连接的压条30；光伏发电单元10的边缘夹设在压条30与支撑部件20之间。

第四，考虑到压条30设置于光伏发电单元10可以进行光电转换面的一侧，且压条30具有透光率有限，甚至不透光，因此，压条30仅覆盖光伏组件10的边缘，以使得光伏发电单元10的光电转换面正常接收光线的照射。
第五，不对压条30的材料进行限定，只要可以利用压条30将光伏发电单元10的边缘夹设于压条30与支撑部件20之间即可。

具体的，压条30可以是金属材质，以起到防雷效果，例如压条30可以是铝合金型材。
本公开实施例通过使光伏发电单元10的边缘夹设在压条30与固定部22之间，可以使光伏发电单元10与支撑部件20固定的更加牢固；同时，由于压条30也具有一定重量，因此，还可增加光伏发电单元10、压条30、以及支撑部件20的整体重量，以避免在强风天气光伏发电单元10、压条30、以及支撑部件20移动，并造成不必要的人员伤亡和经济损失。

第二，不对缓冲部件40的材料进行限定，只要缓冲部件40可以起到缓冲作用，避免压条30损坏光伏发电单元10的表面即可。
示例的，缓冲部件40可以是胶条，胶条的材料可以是三元乙丙橡胶(Ethylene-Propylene-Diene Monomer，简称EPDM)。
本公开实施例中，缓冲部件40具有一定的柔韧性，可设置在光伏发电单元10与压条30之间，将光伏发电单元10与压条30间隔开，以起到缓冲作用，避免压条30损坏光伏发电单元10的表面。
可选的，如图7和图8所示，支撑部件20还包括加强部23，加强部23与固定部22远离承载部21一侧的端部连接、并沿光伏发电单元10指向支撑部件20的方向延伸(即在图8中沿正向下或斜向下的方向延伸)。
需要说明的是，第一，加强部23与固定部22之间的夹角范围可以为30°～150°，例如，加强部23与固定部22之间的夹角为60°、或者90°、或者120°。图8仅示出加强部23与固定部22之间的夹角为90°的情况。
其中，加强部23与固定部22之间的夹角，是指：固定部22远离光伏发电单元10一侧的表面与加强部23之间的夹角。
第二，一个支撑部件20中，可以包括一个、或两个、或三个、或四个加强部23。
第三，加强部23可以与承载部21和固定部22为一体成型结构，也可以经过连接形成一体结构。

本公开实施例中，通过设置加强部23可增大支撑部件20的整体刚度，有效防止光伏组件变形。
进一步可选的，如图10所示，支撑部件20还包括加强连接部，加强连接部用于固定连接相邻加强部23。
此处，如图10所示，加强连接部可包括L形角码400和固定件401，通过L形角码400和固定件401可使相邻的两个加强部23固定连接。
其中，加强连接部可设置在相邻两个加强部23的内侧壁，也可以设置在相邻两个加强部23的外侧壁。图10仅示出加强连接部设置在相邻两个加强部23的外侧壁的情况。
需要说明的是，当一个支撑部件20至少包括两个加强部23、且两个加强部23相邻时，可利用加强连接部固定相邻的两个加强部23。
本公开实施例中，通过加强连接部可进一步增大加强部23的强度，进一步的，增大支撑部件20的强度，可有效防止光伏组件变形。
可选的，如图11所示，光伏组件还包括辅助支撑部件800，辅助支撑部件800与支撑部件20背离光伏发电单元10的一侧固定连接。
需要说明的是，当支撑部件20仅包括承载部21时，辅助支撑部件800与承载部21对应且固定连接；当支撑部件包括承载部21和固定部22时，辅助支撑部件800可以与承载部21和固定部22均对应且固定连接，或者，辅助支撑部件800也可以仅与固定部22固定连接。可选的，辅助支持部800与承载部21之间通过胶粘方式连接；如图11所示，当支撑部件包括承载部21、固定部22、以及加强部23时，辅助支撑部件800与承载部21、固定部22、以及加强部23对应且固定连接，可选的，辅助支撑部件800与固定部22和/或加强部23固定连接，进一步可选的，辅助支持部800与承载部21之间通过胶粘方式连接。本领域技术人员可以理解，以上所选择的用于固定连接的部件可以更改，只要能够达到对支撑部件20进行辅助支撑的目的即可。
本公开实施例中，可以通过辅助支撑部件800加强光伏组件的整体强度，以有效防止光伏发电单元10变形，避免因光伏发电单元10变形影响光伏组件的外观以及影响光伏发电单元10的光电转换性能。
本公开实施例提供一种光伏系统，如图12-16c所示，包括：前述任一实施例所述的光伏组件、与光伏组件的第一端电连接的线缆、以及位于光伏组件的支撑部件20背离光伏发电单元10一侧的槽体60；其中，线缆的第二端放置于槽体60的线缆放置部62中。
其中，线缆包括正极线缆51和负极线缆52，正极线缆51的第一端与光伏组件10的正极接线端电连接，负极线缆52的第一端与光伏组件10的负极接线端电连接。
此处，对于图12、图15b、图16b所示的光伏系统，在组装光伏系统时，先将线缆的第二端通过槽体60上的第一引线孔621放入线缆放置部62中，之后，再将光伏组件与槽体60固定连接。
对于图13、图15a、图16a所示的光伏系统，在组装光伏系统时，可直接将线缆的第二端放入线缆放置部62中，然后将光伏组件与槽体60固定连接。
在此基础上，槽体60设有排水口61，如图15a-16c所示，虽然本公开实施例没有说明槽体60中排水口61的具体位置，但本领域的技术人员应该知道，为了使槽体60内无积水，可将排水口61设置在槽体60远离支撑部件20的一侧表面。并且，槽体60中排水口61的个数，应与槽体60的大小、以及实际应用有关，例如，当槽体60的尺寸比较小时，在槽体60上设一个排水口61即可；当槽体60的尺寸比较大时，可在槽体60上间隔开设多个排水口61。
需要说明的是，第一，不对槽体60的材料进行限定，可选的，槽体60为金属材质，金属材质的槽体60可以起到防雷的效果，且金属材质的刚性较大，可以利用槽体60支撑光伏发电单元10和支撑部件20。例如，槽体60的材料为铝合金。
第二，如图15a-图16c所示，槽体60可以与支撑部件20直接接触并固定连接，其中，图15a和16a所示的槽体60的结构与图14a 所示的槽体60对应，线缆的第二端通过槽体60上表面的开口进入线缆放置部62，图15b和图16b所示的槽体60的结构与图14b所示的槽体60对应。当然，槽体60也可以与支撑部件20间隔设置，并通过光伏系统中的其他部件间接地与光伏组件固定连接，例如其它部件为方通等结构。
此处，如图14b所示，槽体60包括第一引线孔621，线缆的第二端可通过引线孔621放置于线缆放置部62中。为了说明槽体60的引线孔621仅占据线缆放置部62的侧壁的部分区域，图15b和图16b示出了在第一引线孔621处的剖视图，图15c和图16c示出了在除第一引线孔621以外的其他部分的剖视图，从图15b和图16b中可以看出，第一引线孔621并未完全占据线缆放置部62的一个侧壁。
第三，线缆中可以放置在槽体60中的部分都可以称为线缆的第二端。
第四，如图12-16c所示，不对槽体60相对于支撑部件20和光伏发电单元10的位置进行限定，只要线缆的第二端可以放置在槽体60中即可，在一些实施例中，槽体60还对支撑部件20起到支撑的作用。
此处，考虑到线缆长期暴露在外，既影响美观，又容易老化，因此，可将槽体60设置在距离线缆的第一端较近的位置，以使得线缆尽可能多的放置在线缆放置部62中。
进一步的，如图14a-16c所示，槽体60还包括第一连接部63，第一连接部63由线缆放置部62的靠近光伏组件的第一端的边沿，沿与光伏发电单元10的非光电转换面平行的方向延伸；槽体60通过第一连接部63与光伏组件的第一端固定连接。
其中，如图18a-19b所示，第一连接部63可以向靠近与其所在的线缆放置部62的边沿相对的边沿一侧延伸，如图15a-16c所示，第一连接部63也可以向远离与其所在的线缆放置部62的边沿相对的边沿一侧延伸。
此处，当支撑部件仅包括承载部21时，槽体60通过第一连接部63与承载部21固定连接；当支撑部件仅包括承载部21和固定部 22时，槽体60可通过第一连接部63与固定部22固定连接；当支撑部件包括承载部21、固定部22、以及加强部23时，槽体60可通过第一连接部63与加强部23固定连接。
第五，由于槽体60设置于支撑部件20远离光伏发电单元10一侧，因此，光伏组件可以通过槽体60与安装载体连接。其中，槽体60远离光伏组件的一端与安装载体连接。
第六，不对第一连接部63与光伏组件的连接方式进行限定，例如，可以通过螺钉连接或卡接等方式将槽体60与光伏组件固定连接起来。
本公开实施例提供一种光伏系统，通过将线缆的第二端设置在线缆放置部62中，可以避免线缆长期暴露在外，一方面，由于线缆整齐放置在线缆放置部62中，而非暴露在外，可使光伏系统的外观更加美观；另一方面，还可以防止线缆老化、腐蚀；在此基础上，通过在槽体60上设置排水口61，可防止雨水等积在线缆放置部62中，避免对线缆放置部62中的线缆造成腐蚀。
在此基础上，如图17所示，槽体60还包括支撑固定部65，支撑固定部65用于使排水口61与安装载体具有一定高度，以方便槽体60中的水通过排水口61排出。
进一步可选的，如图15b和16b所示，第一连接部63上设有第一引线孔621，线缆的第二端通过第一引线孔621放置于线缆放置部62中。

可选的，光伏系统还可以包括转接加强部，第一连接部63通过转接加强部与光伏组件的第一端连接；如图18a-19b所示，转接加强部70上设有第二引线孔71，线缆的第二端通过第二引线孔71放置于线缆放置部62中。
其中，如图18a-19b所示，转接加强部70可与槽体60的第一连接部63固定连接。
需要说明的是，第一，不对转接加强部70的材料及具体结构进行限定，只要线缆的第二端可以通过转接加强部70即可。
具体的，转接加强部70可以是方通，其材质可以是金属材质，这样一来，转接加强部70不但具有防雷效果，还可以对光伏组件起到支撑作用。
第二，由于槽体60通过转接加强部70与支撑部件20固定连接，因此，转接加强部70的位置与槽体60和支撑部件20的位置对应。
具体的，如图20和图21所示，转接加强部70可以呈块状间隔设置，一个块状的转接加强部70上包括一个第二引线孔71；如图22和图23所示，转接加强部70也可以呈条状，条状的第一连接部70上包括一个或多个第二引线孔71；如图24和图25所示，转接加强部70围成四周，且包括一个或多个第二引线孔71。
本公开实施例中，可通过转接加强部70使得光伏组件与槽体60固定连接，转接加强部70还可起到支撑光伏组件的作用，当转接加强部70为如图25所示的围成四周结构时，转接加强部70还起到对支撑部件20的辅助加强作用，避免光伏发电单元变形。
或者，如图26-29所示，光伏组件与槽体60之间具有间隙，线缆50的第二端通过该间隙放置于线缆放置部62中。进一步，如图27所示，设置多个转接加强部70(图示为2个)将光伏组件与槽体60固定连接。多个转接加强部70之间具有间隙，光伏组件与槽体60之间也具有间隙，从而线缆50的第二端通过光伏组件与槽体60之间的间隙以及两个转接加强部70之间的间隙放置于线缆放置部62中。
此处，如图29所示，转接加强部70可以包括第一固定部701和第二固定部702，第一固定部701与支撑部件20的侧壁固定连接，第二固定部702与槽体60的第一连接部63固定连接。
需要说明的是，第一，当支撑部件20仅包括承载部21时，第一固定部701与承载部21的侧壁固定连接；当支撑部件20包括承载部21和固定部22时，第一固定部701与固定部22固定连接；当支撑部件20包括承载部21、固定部22、以及加强部23时，第一固 定部701与加强部23的侧壁固定连接。
第二，根据光伏组件的尺寸，与一个光伏组件对应的转接加强部70的个数可以是一个，也可以是多个。
第三，不对固定加强部70与第一连接部63和支撑部件20的连接方式进行限定，例如可以利用螺钉使固定加强部70分别与第一连接部63和支撑部件20固定连接。
第四，如图26和图27所示，第二固定部702设置于第一连接部63靠近光伏组件一侧(即第一连接部63的上表面)；如图28所示，第二固定部702也可以设置于第一连接部63远离光伏组件一侧(即第一连接部63的下表面)。
对于上述任一实施例，如图30-33所示，所述光伏系统还包括接线盒80，支撑部件20可以包括镂空区域，接线盒80设置于所述镂空区域中、并与支撑部件20固定连接，即，接线盒80与光伏组件10直接接触，线缆50的第一端通过接线盒80与光伏组件10电连接。
其中，线缆50的第一端与接线盒80中的接线端子电连接，接线盒80中的接线端子与光伏组件10的正极接线端(或负极接线端)电连接。
需要说明的是，每个光伏组件上具有正极接线端和负极接线端，每个接线盒80可以具有一个接线端子，当然，也可以具有两个接线端子；通常情况下，具有一个接线端子的接线盒80，其接线端子只与光伏组件10中的正极接线端、负极接线端中的一个电连接；具有两个接线端子的接线盒80，其两个接线端子可以分别与光伏组件的正极接线端和负极接线端电连接，此时光伏组件10中的正极接线端和负极接线端之间的间距不宜过大，以保证接线盒80的两个接线端子能够分别与正极接线端和负极接线端电连接。
本公开实施例通过将接线盒80设置在支撑部件20的镂空区域中，即，接线盒80设置在光伏组件的非光电转换面，可以使光伏系统的外观更加美观。
可选的，如图34所示，所述光伏系统包括沿槽体60的延伸方 向设置的多个光伏组件，相邻光伏组件串联连接，用于串联相邻两个光伏组件的两个线缆50的第二端在线缆放置部62中电连接。
本公开实施例中，与沿槽体60延伸方向设置的多个光伏组件电连接的多个线缆50，其第二端均可放入该槽体60中。
进一步可选的，如图35所示，光伏系统包括至少两个沿垂直于槽体60的延伸方向排列的槽体60，以及相应地，光伏系统包括沿槽体60排列方向设置的至少一个光伏组件；每个光伏组件的第一端和与其相邻的一个槽体60的第一连接部63连接，每个光伏组件的第二端和与其相邻的另一个槽体60的第二连接部64连接；其中，槽体60的第二连接部64沿与第一连接部63所在的边沿相对的该槽体60的另一边沿延伸、并与第一连接部63相对，每个光伏组件中的第二端与第一端相对。
需要说明的是，第一，如图14a和图14b所示，第二连接部64与第一连接部63的延伸方向可以相同，也可以不相同。
示例的，当第二连接部64与第一连接部63的延伸方向相同时，第一连接部63向靠近第二连接部64一侧延伸，第二连接部64向远离第一连接部63一侧延伸；或者，第一连接部63向远离第二连接部64一侧延伸，第二连接部64向靠近第一连接部63一侧延伸。
当第二连接部64与第一连接部63的延伸方向不相同时，第一连接部63向靠近第二连接部64一侧延伸，第二连接部63向靠近第一连接部一侧延伸；或者，第一连接部63向远离第二连接部64一侧延伸，第二连接部63向远离第一连接部一侧延伸。
第二，虽然光伏组件的第二端和与其相邻的另一个槽体60的第二连接部64连接，但由于光伏组件的第二端并不包括正极接线端和负极接线端，因此，在垂直于槽体的延伸方向上，与同一个槽体60相邻的两个光伏组件之间并非串联关系。
本公开实施例中，可通过与一个光伏组件相邻的两个槽体60将该光伏组件固定在安装载体上。
进一步可选的，如图36和图37所示，串联多个光伏组件的线缆50中汇总线缆的第二端置于汇总线缆槽200中，汇总线缆槽200 中设有与光伏电器系统连接的接口，汇总线缆的正极线缆51和负极线缆52分别与对应的接口连接。
需要说明的是，放入汇总线缆槽200中的汇总线缆50的第二端，为与多个光伏组件中最靠近汇总线缆槽200的光伏组件电联接的线缆50的第二端。
在此基础上，对于上述任一实施例，在槽体60与光伏组件直接接触的情况下，槽体60的第一引线孔621的尺寸应大于或等于线缆50的第二端的尺寸，以使得线缆50第二端通过第一引线孔621进入槽体60；在槽体60与支撑部件20之间设有转接加强部70的情况下，转接加强部70上的第二引线孔71的尺寸、以及槽体60的开口622的尺寸应大于或等于线缆50的第二端的尺寸，以使得线缆第二端通过第二引线孔71和开口622进入线缆槽60。
例如，考虑到线缆50第二端的宽度一般为16mm，线缆第一端和第二端的尺寸一般为10mm，因此，上述第一引线孔621、第二引线孔71的宽度设置为12mm-16mm(例如，第一引线孔621、第二引线孔71可设置为14mm、15mm、16mm中的一种)，上述线缆槽开口622的宽度设置为20～26mm(例如，线缆槽开口622的宽度为20mm)。
此处，当光伏系统包括多个支撑部件20时，在将线缆50的第二端放入线缆槽60的过程中，线缆50的线缆头可能穿过相邻支撑部件20之间的间距，因此，相邻支撑部件20之间的间距的尺寸也应大于或等于线缆50的第二端中线缆头的尺寸。

如图38所示，由于屋面板本体100靠近光伏组件10一侧通常设有多个间隔设置的凸起300，因此，连接件90可以由螺栓91、转接件92组成，由螺栓91、转接件92连接光伏系统(或光伏组件)和屋面板本体100；如图39-图40所示，由于交通工具本体100靠近光伏组件10一侧表面通常为一平面，连接件90可以仅包括螺钉，使用螺钉将光伏组件或光伏系统固定到交通工具本体100上。
其中，屋面板本体100和交通工具本体100的材料可以是铝合金、铝镁合金、不锈钢、镀锌钢等。
