Technical Field
The utility model relates to a battery backplate technical field especially relates to a photovoltaic cell backplate for BIPV.
Background
Building Integrated Photovoltaic (Building Integrated PV, PV) or Photovoltaic (Photovoltaic) Integrated PV. Building Integrated Photovoltaics (BIPV) technology is a technology that integrates solar power (photovoltaic) generation products into buildings.
The problems are that: the photovoltaic cell module is generally formed by hot pressing of glass, cell silicon wafers, EVA and a back plate material, the strength of the cell module is mainly provided by the glass, and the back plate material needs to have good weather resistance so as to prolong the service life of the photovoltaic cell module. In order to achieve sufficient strength, the peeling of the battery assembly must be maintained at a sufficient thickness, so that the battery assembly is generally heavy. Glass is omitted from some small-sized solar photovoltaic modules, and a film material is directly used as a back plate, but the small-sized solar photovoltaic modules cannot be applied to large-sized photovoltaic cell modules due to insufficient strength. In the actual application of BIPV, when it is required to install a photovoltaic cell module on the surface of a building and the top of the building, the weight of the cell module itself becomes an important factor affecting the installation. Therefore, a photovoltaic cell back plate for BIPV with light weight and high strength has to be developed, and the same technical scheme as the present invention is not found through searching.
