solar panel

详情

1.it can be for house using and factory
2.it can used about****5years
3.Solar panels is solar power system, is also the core part of solar power system in the highest value of its role is solar energy into electrical energy, or sent to store up, or battery push work load the quality and the cost of solar panels will directly decided the quality and the cost of the whole system
4.Crystalline silicon materials (including polycrystalline and monocrystalline silicon) is the main photovoltaic material, its market share in *0% above, and in the next a long time also is still the mainstream of solar cells material. Polycrystalline silicon production technology for a long time is in the U.S., Japan, Germany, etc. Of the three countries seven company *0 factories, forming technology blockade, hand the condition of the market monopoly. The demand of polysilicon mainly comes from the semiconductor and solar cells. According to the different requirements for purity, divided into electronic level and the sun energy level. Among them, used in electronic level of about *5%, the sun polysilicon polysilicon accounted for *5%, with energy photovoltaic industry in the rapid development of polycrystalline silicon solar cells, and the speed of growth in the demand for higher than the development of semiconductor polysilicon, predicts ***8 solar polycrystalline silicon the demand for more than electronic level polycrystalline silicon. In ***4 the world solar cells, the total output of only *9 MW and ***4 years of close to ***0 MW, in just *0 years will increase in *7 times. Experts predict solar photovoltaic production
