Solar Panels The Structure And Function
(1) Solar Panels tempered glass: its role in order to protect the main power generation (such as battery), translucent its selection is required:
Solar Panels 1. Transmittance must be high (generally more than 91%);
Solar Panels 2. Ultra-white steel processing.
(2) Solar Panels EVA: used to bond fixed glass and power generation (battery), transparent EVA material directly affect the quality of the component life, exposure to the air in the EVA easy to aging yellow, thus affecting the components of the light In addition to the quality of EVA itself, the components manufacturers of laminated technology is also very large, such as EVA glue degree is not up to standard, EVA and tempered glass, backplane bonding strength is not enough, will cause EVA Early aging, affecting component life.
(3) Solar Panels battery: the main role is the power generation, power generation main market is the mainstream of crystalline silicon solar cells, thin film solar cells, both of their advantages and disadvantages. Crystalline silicon solar cells, the cost of equipment is relatively low, but the cost of consumption and battery sheet is high, but the photoelectric conversion efficiency is also high, in the outdoor sun power generation more appropriate. Thin film solar cells, the relative cost of equipment is higher, but the consumption and battery cost is very low, but the photoelectric conversion efficiency is more than half of the crystalline silicon cell, but the low light effect is very good, in ordinary light can also generate electricity, such as the calculator Of the solar cells.
(4) Solar Panels back: the role of sealing, insulation, waterproof. Generally use TPT, TPE and other materials must be anti-aging, most components manufacturers are guaranteed for 25 years, tempered glass, aluminum alloy generally no problem, the key in the backplane and silicone can meet the requirements.
(5) Solar Panels aluminum alloy: protective laminates, from a certain seal, support role.
(6) Solar Panels junction box: the protection of the entire power generation system, play the role of the current transfer station, if the components of the short-circuit junction box automatically disconnect the short-circuit battery string, to prevent burning the entire system Junction box is the most critical diode selection, The type of battery chip is different, the corresponding diode is not the same.
(7) Solar Panels Silica gel: Seal effect, used to seal components and aluminum alloy frame, components and junction box at the junction of some companies use double-sided tape, foam instead of silica gel, the domestic use of silica gel, the process is simple, convenient, easy to operate, And the cost is very low.
