Use

solar modules are the core of solar photovoltaic power generation system, but also the value of high-power part of the solar power system.Its role is to convert the sun's radiation capacity into electricity, or sent to the battery to store, or to promote the load work. Products have been widely used in space and the ground, used for power generation systems, charging systems, road lighting and traffic signs and other fields, the power and voltage range, high conversion efficiency, long service life.

Specifications

Power generation system of solar photovoltaic cells can be divided into single crystal silicon, polysilicon, amorphous silicon solar cells. Monocrystalline silicon solar cells to high purity single crystal silicon rod as raw material, purity requirements of more than 99.999%. Monocrystalline silicon solar cell photoelectric conversion efficiency is generally more than 17%. Polycrystalline silicon solar cells contain a large number of single crystal particles of the collection, there are a variety of different arrangement of the single composition. With the waste of single crystal silicon and metallurgical grade silicon material melting casting solidification, photoelectric conversion efficiency is generally about 15%.

Solar panels - role

The use of photoelectric effect directly into the energy of light energy, the sun's light energy into electricity, the output DC stored in the battery (chemical storage), use and then release it! There is no storage, electricity storage is another device, and the solar panel does not matter. The battery charge is chemical means.
