However, behind the solar aura, there is still a question that cannot be dissipated: Are Chinese companies really the world's photovoltaic giants? In the end, we are the winners of the industry, but also the indispensable parts of the industry chain?
Relevant data show that in the last ten years, the output value of the photovoltaic industry has grown at an average annual rate of 48.5%, with an increase of 55% in the past five years. Despite the global financial crisis in the past three years, the growth rate of the photovoltaic industry is still as high as 35%, which is an unmatched growth rate in other industries.
In 2009, among the top ten PV manufacturers in the world, China was selected by Suntech Holdings, Tianwei Yingli and Jingao Solar, ranking third, fifth and seventh respectively. If you look at shipments this year, the rankings of Suntech and JA Solar may continue to rise, and German Q-cells will be squeezed out of the top three. Suntech Holdings is also likely to be the world's second largest producer after World First Solar.
However, the growth achieved by Chinese PV companies in recent years has mainly focused on large-scale and low-price. At present, domestic companies have their own large-scale expansion plans, and the scale is unprecedented. The expansion of Suntech, Jingao, Yingli and other companies is still unabated. The three companies will have an estimated 5GW capacity production capacity this year, which is equivalent to China's PV production in 2008. In addition, Changzhou Tianhe, Artes, Tuo Xinneng, Dongfang Risheng, Jiangsu Linyang New Energy, Ningbo Solar, Changzhou Yijing Optoelectronics, Zhengtai Solar, Jiaotong University Taiyang and many other domestic enterprises also have their own large scale. Expansion plan. An internal management of Huadian Group said that if it is not a G-watt expansion, many companies are embarrassed to announce it.
For the just-starting PV industry, scale expansion is indeed very important, but without technology as a support, then Chinese PV companies are also likely to miss the future gold development period, just the backyard processing plants of other companies. In the field of thin film batteries, photothermal and concentrating batteries, Chinese companies are rarely involved. Some new battery technologies have their own limitations in their application areas, so both PV power plant investors and people in related industries are struggling. However, the above problems cannot be completely a reason for Chinese companies not to make technological breakthroughs.
Shi Zhengrong of Suntech once felt that many PV companies in the world are seeking different technological innovations, but they rarely see such a scene in the country. For example, Advent Solar of the United States is conducting a full-back battery technology development, and Solyndra is also experimenting with a thin film on a Water Heater vacuum tube, which now has a capacity of 500 megawatts. Another example is NanoSolar, which is also doing printed thin film solar energy.
China's innovative companies are not without, whether it is equipment or technology, they need to buy from abroad, and then to the country to copy. Now it seems that the ready-made "fetching" may prompt the business to develop faster, but once the technical confidentiality period expires, and equipment supply problems, it will bring a big blow to Chinese enterprises.
In just a few short years, thousands of Chinese PV companies have suddenly emerged, making China the undisputed world's largest PV producer. This is both a miracle and not surprising. Because of the low manpower, land cost and imitation ability, China is difficult to meet in the manufacturing industry. Clothing, toys, mechanical parts, electronic information and other industries have long been fulfilled.
