What is the internal structure of solar panels
EVA used to bond fixed glass and power generation body (such as battery), transparent EVA material directly affect the quality of the component life, exposure to air in the EVA easy to aging yellow, thus affecting the component's light transmittance, thus
In addition to the quality of EVA itself, the components of the manufacturers of the laminated process 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, Affect component life.
3) The main role of the battery 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 suitable for thin film solar cells, the relative cost of equipment, but the cost of consumption and battery
Very low, but the photoelectric conversion efficiency relative to the crystalline silicon cell more than half of the point, but the low light effect is very good, in the ordinary light can also generate electricity, such as the calculator on the solar cell.
