Abstract

The invention provides a photovoltaic metal bottom plate, a photovoltaic roof piece and a preparation method of the photovoltaic roof piece. The photovoltaic metal bottom plate comprises a groove bottom part and two side wall parts, wherein the two side wall parts are arranged on two opposite side edges of the groove bottom part respectively to form a mounting groove; a contact baffle is arrangedalong the length direction of the side wall parts; one side of the contact baffle is connected with the side wall parts and the other side of the contact baffle extends towards one side, far away fromthe side wall parts; and a first pre-set distance is formed between the contact baffle and the groove bottom part. According to the photovoltaic metal bottom plate, the contact baffle increases the bonding area between a filling layer and the mounting groove of the photovoltaic metal bottom plate; and the contact baffle has a limiting effect on the filling layer and the separation probability ofthe filling layer and the mounting groove is reduced, so that the separation probability of a photovoltaic module mounted in the photovoltaic metal bottom plate is reduced.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a photovoltaic metal base plate, a photovoltaic roofing component and a method for preparing the photovoltaic roofing component. Background technique [0002] Building Integrated Photovoltaic (BIPV, BIPV Building Integrated Photovoltaic) technology is a technology that combines photovoltaic cells with the roof of traditional buildings, so as to reduce the energy consumption of buildings through the function of photovoltaic modules. [0003] In the prior art, the scheme of stacking photovoltaic modules on the metal substrate and fixing the metal substrate on the roof is often adopted. In this scheme, the photovoltaic module is bonded and arranged on the metal substrate away from the roof through an adhesive. One side, so as to realize the fixed installation of photovoltaic modules. [0004] However, in the prior art, due to the different weather resistance properties of the...
