2 Aluminum alloy protective laminate parts, play a certain role in sealing and supporting

3 The junction box protects the entire power generation system and acts as a current transfer station. If the component is short-circuited, the junction box automatically disconnects the short-circuit battery string to prevent the whole system from burning out. The most critical part of the junction box is the selection of diodes. According to the type of battery in the component, the corresponding diodes are not the same.

4 Silicone sealing function, used to seal components and aluminum alloy frame, components and junction box junction some companies use double-sided adhesive strip, foam to replace silicone, silicone is widely used in China, the process is simple, convenient, easy to operate, and the cost is very low.

Construction of laminated parts

1 toughened glass: its role is to protect the power generation subject (such as battery), the selection of light transmission is required, transmittance must be high (generally more than 91%); Ultra white tempering treatment.2 EVA: Used to bond fixed toughened glass and 

power generation body (such as battery), the quality of transparent EVA material directly affects the life of the component, EVA exposed to the air is easy to age and yellow, thus affecting the transmittance of the component, thus affecting the quality of the component power generation. In addition to the quality of EVA itself, the lamination process of the component manufacturer is also very important. Such as EVA adhesive viscosity is not up to the standard, EVA and toughened glass, backplane bonding strength is not enough, will cause EVA early aging, affect the life of components.

3 Power generation main body: Crystalline silicon solar cells and thin film solar cells are the mainstream in the market. Both have their own advantages and disadvantages. The equipment cost is relatively low, but the consumption and the cost of the battery are very high, but the photoelectric conversion efficiency is also high. However, the consumption and battery cost are very low, but the photoelectric conversion efficiency is more than half of the crystalline silicon cell, but the low light effect is very good, and it can also generate electricity under ordinary lights.

4: the role of the backplane, sealing, insulation, waterproof (generally with TPT, TPE, etc.) material must be resistant to aging, most component manufacturers are guaranteed 25 years, tempered glass, aluminum alloy is generally no problem, the key is in the backplane and silica gel can meet the requirements. Basic requirements 1, can provide sufficient mechanical strength, so that the solar cell module can withstand the transportation, installation and use of the process of impact, vibration and other generated stress, can withstand hail click force; 2, with good sealing, wind proof, waterproof, isolation of atmospheric conditions on the solar cell corrosion; 3, with good electrical insulation performance; 4, strong anti-ultraviolet ability; 5, the working voltage and output power are designed according to different requirements, and can provide a variety of wiring methods to meet different voltage, current and power output requirements;

5: the efficiency loss caused by the series and parallel combination of solar cells is small;

6: reliable connection of solar cells;

7: long working life, requiring solar cell modules in natural conditions can be used for more than 20 years;

8: The packaging cost is as low as possible under the conditions mentioned above.
