The Solar Panels

Also called "solar chip" or "photocell", solar panel is a kind of photoelectric semiconductor sheet that uses sunlight to generate electricity directly. A single solar cell cannot be used directly as a power source. For power supply, a number of individual solar cells must be connected in parallel and tightly packaged into modules. Solar panel composition and the functions of each part.


Toughened Glass

Its role is to protect the main body of power generation (such as battery), its selection of light transmission is required: 1. Light transmittance must be high (generally above 91%); 2. Super white toughening treatment. 


The EVA

Fixed toughened glass used for bonding and power (battery), the merits of the transparent EVA material directly affect the life of the components, exposed to the air in the EVA aging yellow, thus affect the light transmittance of the component, thus affect the quality of the component's power in addition to the quality of EVA itself, the component manufacturer of laminating process influence is very big, Such as EVA adhesive degree is not up to standard, EVA and toughened glass, backplane bonding strength is not enough, will cause early aging of EVA, affect the life of components. 


Battery

The main role is to generate electricity. The mainstream of the power generation market is crystalline silicon solar cells and thin film solar cells, both of which have advantages and disadvantages. Crystalline silicon solar cell, the equipment cost is relatively low, but the consumption and cell cost is very high, but the photoelectric conversion efficiency is also high, in the outdoor sunlight is more suitable for power generation. Thin film solar cell, relatively high equipment cost, but the consumption and battery cost is very low, but the photoelectric conversion efficiency is more than half of the crystal silicon cell, but the low light effect is very good, in ordinary light can also generate electricity, such as the solar cell on the calculator. 


Backplane

Function, sealing, insulation, waterproof. Generally TPT, TPE and other materials must be aging resistant, most component manufacturers are 25 years of warranty, tempered glass, aluminum alloy is generally no problem, the key is with the back plane and silica gel can meet the requirements. 


Aluminum Alloy

Protective laminate parts, play a certain sealing and supporting role. Junction Box. Protect the whole power generation system, play the role of current transfer station, if the component short circuit junction box automatically disconnects the short circuit battery string, prevent burning the whole system in the junction box is the most critical is the selection of diode, according to the type of battery in the component, the corresponding diode is not the same. Silica Gel. 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 silica gel, silica gel is widely used in China, the process is simple, convenient, easy to operate, and the cost is very low.
