Lang of the solar energy industry by winning the Obama magic

In Electronic Infomation Category: R | on April   18, 2011

After Obama took office, the discussion of new energy sources more and LM337LMX datasheet and more. Today, just as we analyze one of the photovoltaic industry. PV refers to the conversion of light energy into electrical energy by the a function of (PhotovoltaicProcess), made it clear that the solar power generation. Solar power is not at this stage is very popular, but I think the photovoltaic industry is has unlimited potential.

Reduce costs is the key

PV industry chain at the upper, middle and LM337LMX price and lower reaches of three parts: the upper reaches of solar grade silicon, including refining, manufacturing silicon ingots and LM337LMX suppliers and silicon ingot and wafer cutting; middle enterprise responsible for manufacturing batteries; downstream of the battery module assembly and sales focus photovoltaic power generation system. PV industry is a typical pyramid model in which relatively small number of firms in the upstream, midstream operations in the upstream and more than the number of firms, the largest number of downstream businesses. The reason is simple: the technology required for the upstream business is the upper, middle and lower reaches of the highest in three parts, the cost is also the largest. Therefore, the threshold will enter the upstream and downstream relative to the business than the middle is much higher.

Currently, photovoltaic solar energy also requires government subsidies to various aspects, one of the biggest reason is cost of electricity is very high. Today domestic photovoltaic the average cost per kilowatt to 2 yuan, hydropower and coal need only 0.2 yuan per 0.3 million. Electricity paid by consumers are now about 0.6 yuan to 0.8 yuan. How can such a huge photovoltaic power generation needs of the cost, without government subsidies, to the consumers home, how much to pay them in the end? Although Governments have realized

new urgency of energy, and implemented a series of subsidy programs to promote the development of photovoltaic solar energy. But in the end, PV is not yet universal reason, largely because the technology is not mature enough, power generation, photovoltaic power generation cost is not enough to integrate into the community at every level of life. In the photovoltaic industry chain at every stage, every manufacturing process, especially in the upstream refining of silicon, the cost remains high. Of course, the major successful companies aware of the crux of the problem, so in order to reduce costs, the major R & D R & D, M & M, in the shortest possible time in order to get the latest technology, among the leading companies in many other opponents to dominate the whole industry.

We know that to enhance the photovoltaic cell technology is the photovoltaic industry, the most critical step that can greatly reduce the cost, practical, low price of photovoltaic power generation, so that more consumers are willing to use photovoltaic solar power. To achieve this goal, the major companies out all of the law: the industry leader Sharp of Japan developed its own combination of architecture and photovoltaic devices (BIPV) technology; Germany Q-Cells through the control and acquisition of other companies derived technologies, such as and combined group of companies in Sweden SilbroAB made of copper indium gallium selenide thin-film technology; Suntech Power (SuntechPower) will focus resources to enhance the conversion efficiency of photovoltaic cells, the development of "Pluto" patent technology, hoping to silicon photovoltaic efficiency of 20%.

Orientation of major companies may not be the same, but achieving the same goal is to enhance photovoltaic solar cell technology to reduce the cost of photovoltaic power generation, to integrate into the life of this goal.

Stable supply of raw materials

In the photovoltaic industry in this industry, first of all to have a stable supply of raw materials, with the increase of production capacity, further promotion to increase sales in different channels.

Admittedly, the raw material silicon for photovoltaic cells is still the mainstream of the entire PV industry, even if the major companies working to develop thin film solar cell technology, can not replace the silicon in a short time the battery market status. One can imagine a reasonable price to obtain sufficient silicon material is in this fast-growing photovoltaic industry, an indispensable prerequisite. That is, if companies can not stabilize the supply of silicon materials, it would not talk to the production.

Silicon is the second abundant element in the earth, the amount of abundant mineral resources but also easier to mining, there is no shortage of truth. However, in addition to silicon photovoltaic cells outside of raw materials, but also LCD LCD televisions, computer chips, etc. in the semiconductor industry to raw materials. In the past, almost all the supply of silicon material is the semiconductor industry, provided only a small part of the PV industry. However in recent years, computer chips, LCD TVs and other LCD rapid development of the semiconductor industry, for the increasing demand for silicon material. Meanwhile, the PV industry is also booming, with the silicon content has expanded each year, the amount of 2003 to 2005 is to skyrocket, the demand for the semiconductor industry began to close, even more than the growth in silicon production, which led to the shortage of silicon, silicon material prices have increased. Solar grade silicon by the 24 dollars per kilogram in 2003 rose to 40 U.S. dollars per kilogram in 2005, an increase of 67%. Although the production of silicon manufacturers are expanding production capacity, but the shortage in 2008 to 2010 to resolve.

Then PV companies to stabilize the supply of silicon materials through what means can it? Generally speaking, there are two main ways: One way is to cooperate with the upstream business, such as long-term pricing agreement signed to ensure future supply of raw materials; Another method is based on corporate strategy involved in the upstream business. Sharp of Japan, for example, long-term strategy of the enterprise and use its own strength to develop upstream business, Toyama, Japan, in 2007, set the plant in the production of silicon materials, the same time, it passed in 2006, Sumitomo Corporation and the upper reaches of the leading enterprises REC of Norway signed a 6 year silicon supply contract.

Increase production capacity and sales

With sufficient and stable supply of raw materials, the necessary to actively expand production capacity to ensure adequate to meet the huge demand for manufactured goods. The PV companies are expanding production lines to Chinas Suntech Power were the most significant achievements: In 2003, annual production capacity of photovoltaic cells is 30MW, is expected by 2010, annual capacity of 1000MW, the equivalent of 65% compound annual growth rate. Suntech established in 2001, 2004, annual production of the worlds top 10 in 2005 to 8 in the world, even in 2006 jumped to No. 4 worldwide! In just four years, from a small Chinese Suntech photovoltaic cells to become the worlds top five corporate production company and sold to different countries and regions the world.

Is part of the next increase in production capacity to increase sales. Traditionally, solar companies will step up to the module supplier, system suppliers, distributors and construction contractors to communicate, to understand market needs and increase sales channels. But I think that this fact alone is not enough. Since the concept of photovoltaic power generation is not fully universal in their daily lives, so the demand for them to increase sales of existing only a passive strategy, photovoltaic enterprises should take the initiative to increase consumer demand for photovoltaic power generation is the nature of the industry.

How should increase consumer of photovoltaic power generation needs? We know that the concept of peoples lives in PV is not fully universal, so the companys strategy will naturally be used to enable consumers to know and enjoy the benefits of PV. Through government policies and subsidy schemes, large enterprises in the installation of large-scale photovoltaic power generation systems, organizing public lectures, and expand the application of photovoltaic power generation, so that consumers, whether at home, work place, leisure can enjoy the light entertainment volt power benefits of solar power to sneak into the part of life.

Regardless of where the focus of major companies, we can easily find their goal is to enhance technology to reduce electricity costs. And because the first generation of photovoltaic cells (in crystalline silicon materials) cost reduction is limited, we expect the development direction of photovoltaic cells based on thin film technology will be the focus of the unlimited expansion of photovoltaic technology.

In addition to upgrading technology, photovoltaic cells enterprises should perform the appropriate supply chain strategies to meet the needs of the market. Through long-term contracts or self-development business to the consolidation of upstream raw materials (silica material) for supply to ensure an endless supply of silicon materials after production of photovoltaic cells with increased use of photovoltaic industry, national government preferential policies to increase awareness of PV power generation in order to increase awareness of the needs of photovoltaic power generation, photovoltaic power generation in order to bring them every bit of daily life.
