PV industry will change the world
The best way to use solar energy photovoltaic conversion, is the use of photovoltaic effect, so that the sun shines on the production of silicon materials, direct current power. Application development to the formation of silicon material called the photovoltaic industry, the industrial chain, including production of high purity polysilicon, solar cell manufacturing, solar module production, manufacturing, and AD7895AR-10 datasheet and other related production equipment.
P> 76% of the land of abundant light, a more uniform distribution of energy resources; and AD7895AR-10 price and hydropower, wind power, nuclear power compared to solar power without any emissions and AD7895AR-10 suppliers and noise, application of technology is mature, safe and reliable; the exception of the size of the grid and off-grid applications, solar energy can also be pumped, superconductivity, batteries, hydrogen storage and other methods, solar + storage almost meet the energy needs of Chinas future stability.
Solar energy is the next most clean, safe and reliable energy, developed countries are the development and utilization of solar energy revolution as the main long-term planning, the photovoltaic industry is increasingly becoming an international following IT, after another explosion in the microelectronics industry growth industry. P>
With renewable and environmentally friendly solar power and other characteristics, the advantages to many countries including China, will focus on the development of solar energy as a new energy industry. China PV products are supplied to U.S. and European markets, the domestic market share is small. In recent years, due to the increasing market demand for Europe and America, China PV industry has achieved rapid development in recent years, the average annual growth rate of 5 to 40%. Further increase in the policy context of efforts to support the future growth prospects for the PV industry will be more broad. P>
PV industry chain from upstream to downstream, including the industrial chain, including polysilicon, wafers, cells and cell components. In the industrial chain, from polysilicon to the battery components, the production of increasingly low technical threshold, and accordingly, the number of distribution companies is also increasing. Therefore, the profits of the entire PV industry chain mainly in the upstream polysilicon production process, the profitability of the upstream business was better than downstream. P>
Present, Chinas polysilicon production for profit in the final battery component products the highest proportion of total profits, about 52%; battery components production accounted for about 18% of profits; and cell and wafer production proportion of profits were about 17% and 13%. P>
Since 2008, polysilicon prices decline began to appear more substantial, to the present, the domestic spot price of polysilicon from last years 500 U.S. dollars / kg down to 100-150 U.S. dollars / kg. P>
Polysilicon capacity expansion too fast, and relatively slow growth in demand is the main factor leading to price decline. According to the companys forecast iSuppi, 2009, the global polysilicon supply will double, while the growth in demand by only 34%. Therefore, there is further decline in the price of polysilicon possibility. iSuppi even said that by 2010, when the spot price of polysilicon will be reduced to 100 U.S. dollars / kg, which would greatly reduce the profitability of the polysilicon suppliers. P>
Prices of polysilicon solar cell manufacturers to thickening of the profits, but also pure silicon there is a big business risk. Both the upstream polysilicon suppliers, or downstream of the solar cell manufacturers, silicon manufacturers technical problems do not exist. When both the upstream and downstream businesses into the silicon when the silicon wafer business by sharply squeezing the profits of the chain.
