Problems solved by technology

However, the service life of the glue is extremely difficult to reach the same life as that of photovoltaic products, and the temperature rise of photovoltaic products will further reduce the service life of the glue
This makes the structural life of the adhesive solution not match the power generation life of the components, resulting in secondary maintenance costs and even the loss and damage of batch components. At the same time, this solution cannot meet the long-term waterproof function of the building

Abstract

The invention relates to a flexible photovoltaic module integrated structure and system and an installation method. The structure comprises a flexible photovoltaic module, a bonding layer and an auxiliary waterproof coiled material which are integrally formed in a laminated manner; and the back surface of the auxiliary waterproof coiled material is provided with a hot air welding area. The method comprises the following steps that: each layer of material of the flexible photovoltaic module and the auxiliary waterproof coiled material are laminated and packaged, so that integration can be realized; a main waterproof coiled material is arranged on a roof, and a hot air welding area corresponding to the hot air welding area on the auxiliary waterproof coiled material is formed on the whole front face of the main waterproof coiled material; and the hot air welding area on the back face of the auxiliary waterproof coiled material and the hot air welding area on the front face of the main waterproof coiled material are attached and subjected to hot air welding. A photovoltaic module or a panel fails to be connected in a gluing mode when being applied to the building field, meanwhile, the material cost and the installation cost of a product are greatly reduced due to the fact that no structural part is used. With the flexible photovoltaic module integrated structure and system and the installation method adopted, the above problems can be solved, the verification of the wind uplift resistance of a roof system under the wind pressure of plus or minus 5000 Pa indicates that the installation structure is safe and reliable.

Description

technical field [0001] The invention belongs to the field of photovoltaic products, and in particular relates to an integrated structure of a flexible photovoltaic module, a system and an installation method of the system. Background technique [0002] Due to the limitation of installation conditions, the existing photovoltaic modules or panels are pasted with back adhesive or sealant or structural adhesive when installed on the roof. However, the service life of the glue is extremely difficult to reach the same life as that of photovoltaics, and the temperature rise of photovoltaic products will further reduce the service life of the glue. This makes the structural life of the adhesive solution not match the power generation life of the components, resulting in secondary maintenance costs and even a batch of components falling off and damaged. At the same time, this solution cannot meet the long-term waterproof function of the building. Contents of the invention [0003]...
