    Tempered glass: its function is to protect the main body of the power generation (such as battery film), light transmission of its selection is required:

    1. transmittance must be high (generally 91% or more);

    2. Super Steel treatment.

    Eva: Used to bond fixed tempered glass and power generation body (battery), transparent EVA material quality directly affect the life of components, exposed to the air Eva easy aging yellowing, thus affecting the light transmittance of components, thus affecting the components of the power generation quality, in addition to the quality of Eva itself, Component manufacturers of the laminating process is also very large, such as the EVA adhesive not standard, Eva and tempered glass, back plate adhesion strength is not enough, will cause premature aging of Eva, affecting the life of components.

    Battery film: The main role is to generate electricity, the main market of power generation is crystalline silicon solar cells, thin film solar cells, both have advantages and disadvantages.

    Back PLATE: function, seal, insulation, waterproof. Generally used TPT, TPE and other materials must anti-aging, the majority of components manufacturers are guaranteed 25, tempered glass, aluminum alloy generally no problem, the key in the backplane and silicone can meet the requirements.

    Aluminum alloy: The protective layer of the pressure, a certain seal, supporting role.

    Junction box: Protect the entire power generation system, play the role of the current transfer station, if the component short-circuit junction box automatically disconnect short circuit battery string, to prevent the burning of the entire system junction box is the most critical of the choice of diodes, according to the components of the type of battery, the corresponding diode is not

    Silica gel: sealing function, used to seal components and aluminum alloy frame, components and junction boxes at the intersection of some companies use double-sided tape, foam to replace silica gel, the domestic general use of silica gel, simple process, convenient, easy to operate, and the cost is very low.
