Background technique

With the large-scale application of photovoltaic modules in power stations, how to reduce the cost of using photovoltaic modules has attracted much attention, and reducing the installation cost of photovoltaic modules is an important factor that needs to be considered. During the installation process, the size of the photovoltaic module is a direct factor affecting the installation cost. Compared with installing several small-sized photovoltaic modules in batches, installing one large-sized photovoltaic module at one time can shorten the installation time and save brackets and auxiliary materials. Therefore, making photovoltaic modules into large sizes is one of the ways to reduce installation costs. At present, due to the limitation of solar cell processing equipment, the size of photovoltaic modules cannot be made very large. Even if they are made into large sizes through internal splicing processing, the scrap rate and cost are high. Therefore, how to make the solar photovoltaic module into a large size is a current technical problem while ensuring the reduction of the scrap rate. The Chinese patent No. ZL200920210087.x discloses a connecting member of a solar photovoltaic module with an "I"-shaped cross section. The two sides of the member are provided with slots with the same thickness as the photovoltaic module, which is convenient for installation. However, the connecting member It is not suitable for large-size photovoltaic modules. When the length of the photovoltaic module is greater than the length of the connecting member, the supporting strength is insufficient and the reliability is not high. the
