Briefly explain why solar cells are made into components
The main photovoltaic material is the crystalline silicon material (including polysilicon and monocrystalline silicon), this material is high hardness, brittleness, uneven force easily brittle, exposed to the air easily oxidized, and the use of the process can not
Components are made in order to better protect the crystalline silicon material is not destroyed, the components generally by the tempered glass, EVA, battery, TPT, aluminum frame and other materials, so that the components, the service life of up to 20 years The
The electrical performance parameters of solar cells are: voltage, current, capacity, type, charging rate and so on. The voltage parameter of the battery refers to the operating voltage of the battery, that is, the voltage that can be supplied to the device. Current, refers to the maximum discharge current of the battery. Capacity, refers to the total discharge power of the battery, with An / hour (A / H) said.
