Solar Cell

For the global PV business, if the new energy policy that the world is the rapid rise of this new engine sunrise business, high technology can be said that from the laboratory to the marketplace midwife. Obviously, the technologies development, industrial development and policy direction have a clear premise, for those trying to enter the photovoltaic business to capture opportunities in a lot of domestic enterprises, a clear awareness and understanding of the entire PV business ecosystem, the scale of investment and technical requirements becomes particularly essential.

Upstream: who is the King owns silicon

In the global PV business chain, high-purity silicon materials (purity of 99.9999% or more) is Suntech production such as photovoltaic solar cells needed for the core material. As a result, the high-purity silicon material in the mining, refining and production of photovoltaic industry clusters has grow to be the most upstream business. At present, despite the fact that the silicon raw material mineral reserves in China account for 25% of the world’s total reserves (silicon itself is the world’s richest mineral reserves 1), simply because the production of silicon materials for solar cells is mainly monocrystalline silicon and polycrystalline silicon, They are extracted by various techniques to extract raw supplies made from silicon, silicon raw materials while China’s current refining technologies lags far behind the original Western developed countries (the highest national level of only 99.5% extraction), resulting in domestic Suntech days Wei Ying Lee and other raw supplies required for solar cell manufacturers will need to import most. Thus, not only significantly increase the production costs, but also restricted the PV business in our country to the upstream development of insurmountable “bottleneck.”

As the solar cell production to meet the wants of high-purity silicon production core technology lies in the hands of a couple of businesses in Western developed countries, coupled with high-purity silicon material can also be employed for military industry, thus introducing the core technologies is extremely hard. Also, from an investment perspective, a 1000 tons polysilicon production lines, just as a medium of modern petrochemical organizations, engineering design not only complex, high power consumption (annual output 1000 tons polysilicon production lines installed capacity of power supply requirements of 98 000 kw, the total power consumption is 250 million kwh), and total investment in China is as high as 10 billion, even though 1000 tons / year is now globally recognized high-purity silicon material production of the smallest economies of scale. Far more importantly, access to the industry’s most essential threshold is not capital, but technologies.

It is understood that although China’s polysilicon industry commence earlier (50 years of the 20th century), but modest production scale, backward technologies, environmental pollution, consumption, high price, most businesses have discontinued due to loss or Transferring to 2004, only Emei Semiconductor Material Factory and Luoyang Monocrystalline Silicon Co., Ltd. The two producers, production capacity is only 100 tons / year to meet the wants of the silicon solar cell production output of only 80 tons of material reality. Experts predict that by 2010 China’s production of silicon for solar cell demand expected to reach 4,365 tons in 2015 to 16,200 tons. Without the intellectual property rights change the status of the domestic production of polysilicon, silicon materials industry in China is subject to international market conditions will not change, this will endanger the further development of PV industry in China.

In fact, in all countries work together to promote a new energy policy, the PV business in the past 5 years, rapid development has led to meet the solar grade silicon material is in short supply situation, the marketplace price is singing along: 2003 kg is 24 dollars 2004, rose to 32 U.S. dollars, by the end of 2005 rose to 80 U.S. dollars is jump up about. For that reason, the PV business chain, the upstream raw materials on the significance of solar businesses like “food”. Market analysts have even predicted: “For the solar cell company, now even the future for a long time, the key is not a production capacity and sales, but whether there is sufficient supply of raw supplies.”

In reality, Suntech IPO in the NYSE listing roadshow last year’s procedure, foreign investors are most regularly asked question is the raw material in 2006 is not implemented? In its prospectus is a clear indication, they raised nearly 400 million U.S. dollars in money, there will be 100 million U.S. dollars for the buy of raw supplies or a down payment in order to further control the raw material. Everbright Securities analyst Han Ling Energy IPO in the next day after Suntech also said: “The only deal well with the upstream silicon raw material supplier relationships, Suntech continued strength no dilemma.” Relevant foreign securities analysis report also noted that in the next two , the silicon material shortage will be the solar business, the most crucial risks.

As a result, in the PV industry chain, the upstream high-purity silicon production enterprise owned by Silicon king is real. In view of this, last November, held in Beijing the polysilicon (one high-purity silicon material) the “Eleventh Five-Year” Conference on Science and Technology Development, Chinese Academy of straightforward aquatic said in his speech: “Our country really should establish a polysilicon base, the base of the output can go to thousands or even hundreds of billion billion. If we can develop numerous such bases in our country’s comprehensive national strength will be significantly increased. ”

How would you like to make solar panel and then save some money as well? This sounds like a hobbyists’ dream project. But hear me out 1st. Having your own solar cell can cut down on that power bill and save you some money.

Making your own solar and wind power for much less than

Solar power has been used for power generation for cars and offices alike. It has proven to be so helpful that solar panels are now being employed for homes too. There are companies that manufacture and install solar panels for residence use. However, these can be quite expensive and can price thousands of dollars. So some folks thought about making their own solar panels. And guess what? It worked! Not only have they saved money from the cut down from the grid energy consumption but also from the construction and installation of the solar panel.

There are guides and instructions telling your how to make solar panel that are obtainable on the Net. You can just search “how to construct solar cell” or “DIY solar panel” and you’ll get hundreds of hits. Just click on these links for info on how to make your own cell. Just be watchful of the information that you’re getting. You never know when individuals are just scraping money off you. So read commentaries and reviews on firms or people that offer you instructions on how to construct your solar cell.
