Development prospect of photovoltaic industry

Photovoltaic industry is renewable, sufficient, safe, extensive and clean, which also makes other countries, including China, regard solar energy as one of the key new energy industries. This paper analyzes the development prospect of photovoltaic industry from the aspects of development process, development status, development trend and market status.

Photovoltaic industry, referred to as PV (photovoltaic). 76% of China's land has abundant light and the distribution of light energy resources is relatively uniform; Compared with hydropower, wind power and nuclear power, solar power generation has no emission and noise, mature application technology, safety and reliability.

1、 Development history and current situation of photovoltaic industry

Global overcapacity and anti-dumping led to the industry trough, and the domestic photovoltaic market boosted the industry boom. At the beginning of the development of China's photovoltaic industry, China mainly exported photovoltaic related products. In 2011, China's photovoltaic installed capacity accounted for only 4.9% of the world. At this time, China produced 34.9% of polycrystalline silicon, 55.6% of silicon wafers, 60.0% of batteries and 60.0% of modules in the world. Due to the influx of a large number of funds, the photovoltaic capacity expanded rapidly. In 2011, the global capacity was 60GW, an increase of 172.7% year-on-year. In 2011, the demand of the global photovoltaic industry was only 30GW, and the overcapacity doubled, resulting in a sharp decline in the prices of photovoltaic related products. The price of polysilicon components fell from 16.03 yuan / watt to 4.10 yuan / watt, a decrease of 74.4%. The decline in the price of photovoltaic products has seriously compressed the benefits of China's photovoltaic industry. At the same time, Europe and the United States have conducted anti-dumping investigations on China's photovoltaic modules and parts, which is a fatal blow to China's photovoltaic industry, which has entered the cold winter. The sales profit margin of the whole industry has fallen to 2.2%, the lowest level in history.
