[0002] As the concept of green living is gradually accepted by modern people, people often install photovoltaic panels on the roof to obtain clean energy. In the relevant technology, photovoltaic panels are flat panels. In order to ensure the matching size of two adjacent photovoltaic panels, the electrical components that electrically connect the two adjacent photovoltaic panels need to be placed on the front of the photovoltaic panel, that is, the electrical components will be exposed outside the photovoltaic panel, which will greatly reduce the service life of the electrical components and increase the frequency of repair and maintenance of the photovoltaic panel. Utility Model Content
