The prospects for solar cells and solar power generation Analysis

Battery inverter system is a very important component. Users to buy batteries, they should choose good quality and large variety of power, large-capacity battery to use for a long time for high-power electrical equipment at the same time the moment to start to provide adequate current. For some high-power electrical equipment, it is recommended batteries should be 200AH (1000W), another big power, it is best to use 400AH battery.
How to use electrical appliances in accordance to determine the battery capacity, the simple way is to use electrical appliances of all power, multiplied by the battery each time the use of the time between charging intervals.Dell INSPIRON 1300 AC Adapter
Computing unit of electrical power is nothing but power, or volt-ampere, the following per day to recharge a battery, for example, the specific results are as follows:
Load Power consumption The use of time (between charging) Watt hours (power × the use of time)
TV and VCD 115 watts 3 hours (day 1 hour) 345
Coffee 750 watts 1 hour (20 minutes per day) 750
Microwave 800 watts Half an hour (10 minutes per day) 400
Total 1665 W 4.5 hours 1495 The current domestic solar silicon production enterprises are mainly monocrystalline silicon factory in Luoyang, Hebei ningjin monocrystalline silicon base and Sichuan Emei Semiconductor Materials Factory and other manufacturers, including Hebei ningjin silicon base is the world's largest solar silicon production base, accounting for The World Solar silicon market share around 25%.

In the solar cell material downstream market, Dell INSPIRON B130 AC Adapter the current domestic production of solar cells are mainly Suntech companies, Nanjing China Light and Power, Baoding Yingli, Hebei crystal Australia, Solarfun Power Holdings, Suzhou Artes, Changzhou Trina, Yunnan days up to photovoltaic technology, Ningbo Solar Electric Power, Kyocera (Tianjin) Solar Energy and other companies, a total annual production capacity of 800MW or more at.
In 2009, the State Council, according to a letter provided by the workers reported that polysilicon production capacity surplus, the actual industry people are not recognized by Science and Technology has indicated that polysilicon production capacity is not excessive [1].
The prospects for solar cells and solar power generation Analysis
At present, the application of solar cells from the military and aerospace fields, into the industrial, commercial, agriculture, communications, household appliances,  and utilities sectors, in particular, can be scattered in remote areas, mountains, deserts, islands and rural areas to use in order to save cost expensive transmission lines. But at this stage, it is still an expensive issue a 1kW power need to invest tens of thousands of dollars, so large-scale use is still subject to economic constraints.
But in the long run, with the improvements in solar cell manufacturing technology and new optical - electrical conversion devices, invention, national protection of the environment and the huge demand for clean, renewable energy, solar cells will continue to compare VGP-BPS8 the use of solar radiation practical means for the future of mankind on a large scale use of solar energy to open up broad prospects.

The status quo of China's solar cell industry
China's research and development of solar cells attached great importance, as early as 75 period,VGP-BPL2 the amorphous silicon semiconductor research work has been included in major national issues; 85 and 95 during the research and development in China to focus on large area solar cell and so on. In October 2003, the National Development and Reform Commission, Ministry of Science and worked out the next five years, solar energy resource development plans, Development and Reform Commission "Bright Project" will raise 10 billion yuan for promoting solar energy technology, plans to solar power by 2005 system's total installed capacity reached 300 MW.
In 2002, the relevant state ministries and started the "western provinces and autonomous regions without electricity Rural electricity Scheme", through solar and small wind power to solve seven provinces and autonomous regions in western rural electricity without electricity problems. The start of this project greatly stimulated the solar power industry, China has built several solar cell packaging line, so that the annual solar cell production capacity is increasing rapidly. At present, 10 of China's solar cell production line, annual production capacity of about 4.5MW, of which eight production lines VGP-BPS2 are imported from abroad, and in this eight production lines, among them, six monocrystalline silicon solar cell production lines, 2-Si solar cell production lines. Experts predict that China's current annual demand for PV market 5MW, 2001 ~ 2010 years, the annual demand will reach 10MW, starting in 2011, China's PV market will be greater than the annual demand 20MW.

Matching with the inverter battery should charge and discharge can be deep-cycle lead-acid battery. Deep-discharge function for battery, the power unit of measurement is generally ampere hours (AH), it shows that the unit time (usually 20 hours) can provide current values. Hp laptop battery As for the 100AH battery capacity that can be provided within 20 hours consecutive five amps of current, that is, 20 × 5 = 100
