Zhao Feng, Chairman of China Optoelectronics Energy Co., Ltd., Leads the Global “Integration of Photovoltaic Environment”

When you visit the China Pavilion during the 2010 Shanghai World Expo, you will see a wonderful effect created by the color solar modules on the viewing platform 1 km long from the entrance to the exit. The "new Kyushu Qingyan" garden landscape echoes each other and complement each other. Apart from admiration, perhaps you do not know that this set of high-tech products with independent intellectual property rights was developed by a domestic company. It is located in Hunan High-tech District, Hunan, China Shenzhou Photoelectric Energy Co., Ltd. (hereinafter referred to as “Shenzhou Optoelectronics ").

It is understood that Shenzhou Optoelectronics has taken the lead in introducing the concept of "integrated photovoltaic environment" (EIPV) in the world, and has completed a series of high-efficiency color solar power system application projects under the guidance of this concept. The aforementioned China Pavilion project is the concept. The concrete embodiment and lively interpretation. Why does Shenzhou Optoelectronic propose the concept of EIPV? National Development and Reform Commission recently introduced the photovoltaic electricity benchmark price policy influence geometry? How is China's photovoltaic new energy application going?

Feeling "Integrated Photovoltaic Environment" (EIPV)

Question: Why does Shenzhou Photonics propose the concept of EIPV?

Zhao Feng: We proposed the concept of the EIPV mainly for the following two aspects.

First of all, solar photovoltaic power stations need to occupy a large amount of land (approximately 1 million square meters of power plants with 1 MW). Deserts and Gobi Deserts far from human production and living areas have sufficient land to build large-scale photovoltaic power plants. However, long-distance transmission and distribution costs are high. Cities that require large amounts of electricity cannot provide enough land to install large-scale solar power plants. Therefore, the unique advantages of EIPV will surely become a trend for solar photovoltaic applications.

Secondly, BIPV is the main application direction of photovoltaic power generation systems. However, the application of conventional solar cells to buildings is subject to certain restrictions because of the appearance of buildings as environments and urban landscapes. Very high, whereas conventional solar cells have only a single color (blue or black) and are not in harmony with the environment. Through the production process of color solar cells, we can provide solar cell modules of various colors according to the requirements of architecture and environment, and realize the integration with the buildings and the surrounding environment.

Question: In terms of practicing the concept of EIPV, apart from the China Pavilion project of the Shanghai World Expo last year, what other projects are being implemented or planned by Shenzhou Optoelectronics?

Zhao Feng: The high-efficiency color solar power generation system technology used to implement the concept of EIPV has reached the world's advanced level. The photoelectric conversion efficiency of solar cells of various colors can reach over 16%. Last year, we cooperated with the Chinese Academy of Sciences and completed the localization of equipment. Work, and have the conditions for industrial development.

In Asia, we have completed the project of the China Pavilion at the Shanghai World Expo; in Europe, we have basically agreed to install color photovoltaic modules in the Vatican Cathedral; in North America, we are also contacting relevant parties in the United States and actively strive to bring our colors Components are installed to the White House. If these three projects can be completed, it would be equivalent to setting up three billboards in landmark buildings with world influence. This will definitely enhance the visibility of China's color photovoltaic cell components and better promote our consistent advocacy. The EIPV concept.

Strive to create "a hundred years old shop"

Question: In the future, where is Shenzhou Optoelectronics planning to promote the development of the photovoltaic industry?

Zhao Feng: As a high-tech enterprise, Shenzhou Optoelectronics does not want to create a company with heavy assets and repeated expansion of production scale, but instead becomes a company that focuses on technological innovation and marketing. In fact, since the establishment of the plant in August 2008, we have made great achievements in technological innovation. Through the China Pavilion project of the World Expo 2010, we achieved large-scale production of color batteries last year, and we have 11 PV patent technologies. We plan to complete the IPO in 2013 to achieve the first phase of the company's development goals; the second phase of the goal is to make the company bigger and stronger; the third phase of the goal is to achieve sustainable development of the enterprise, to make China's optoelectronics "a hundred years old shop".

In terms of specific project planning, we will mainly promote the completion of the following projects during the 12th Five-Year Plan period:

Changsha City Cross River Tunnel Solar Power. The scope of the project includes three river crossing tunnels (Xiangjiang and Liuyang Rivers) to be completed and open to traffic in Changsha City, with a total installed capacity of 2MW. The project is scheduled to be completed by the end of 2012. It is estimated that during the project operation period, the average annual power generation will be 1.8 million kW·h, and the total project investment will be approximately 50 million yuan.

Orange Isle Sun Island project. The project is located in Orange Island, Changsha, with a construction scale of approximately 30,000 m2 and an installed capacity of 2MW. It is scheduled to be completed by the end of 2014. It is estimated that during the project operation period, the average annual power generation will be 1.8 million kW·h, and the total project investment will be approximately 50 million yuan.

New Bright Project in Xinjiang. Through the national financial subsidies and the company's self-funding, Xinjiang Kazak and Uighur herdsmen provide 100,000 sets of photovoltaic off-grid power generation systems free of charge, each system generating power of 100 watts, the service life of more than 25 years, to solve watching television, lighting, Problems such as mobile phone charging, computer Internet access, etc., enabled herders to see the sound of *** in time and conduct free training for local herders to ensure long-term use of the power generation system.

Question: Do you think that China still has problems that need to be solved in promoting the development of the photovoltaic industry?

Zhao Feng: At present, the biggest problem facing the development of China's photovoltaic industry is the lack of the Chinese market. China's 95% of solar PV modules are sold abroad. Once the international market fluctuates, the entire industry will follow ups and downs. Faced with this situation, we need to work hard to reduce the price of crystalline silicon raw materials and improve the photoelectric conversion efficiency. Through hard work, I believe that China will achieve a “one dollar project” (photovoltaic power generation cost will be 1 yuan/kWh) in 2-3 years, and realize parity internet access in 3-5 years. By then, China’s photovoltaic industry will usher in an outbreak period, and the photovoltaic industry will be able to A child who catches a cold easily grows into a strong young man. The "12th Five-Year Plan" period is the key moment for the development of photovoltaics.

Another problem is that some local governments and related departments have misunderstandings in promoting the development of new energy industries and low-carbon economy. This has also led to difficulties in the promotion of new energy products such as photovoltaics. If some leading cadres hold an attitude of not understanding and distrusting new energy sources, they think that “energy saving is not saving”, and they are skeptical or even restricting their development with the attitude of “doing no work but not seeking success”; building a low-carbon city At that time, some local leaders often saw only "throttling", that is, the importance of energy conservation and emission reduction work, but they ignored the "open source", that is, the positive significance of promoting new energy development work. In fact, "open source" and "throttling For the development of a low-carbon economy, it seems like two wheels of a car and two wings of a bird should be given equal importance. They are indispensable.

Photovoltaic power generation is not "junk power"

Question: At present, there are grid companies that think of photovoltaic power generation as "green waste electricity." What do you think of this?

Zhao Feng: This evaluation is biased. It is undeniable that photovoltaic power generation will change from a square wave to a sine wave after the direct current becomes an alternating current. It will inevitably lead to a higher harmonic wave. The harmonic component that appears will actually affect the quality of the power grid to some extent. However, we cannot rely on this as "garbage electricity."

As the electrical stability of solar energy is very good, and the level of domestic inverter technology is also very high, so the previously mentioned harmonic component has been less than 3%, and has little impact on the power grid. At the same time, the fact that photovoltaic power generation can be accessed in Germany also proves that "photovoltaic power generation is waste electricity." This argument is biased.

In fact, the real root cause lies in the low enthusiasm of the power sector in the monopoly of the industry to promote new energy sources. The development of new energy requires the power sector to speed up the construction of smart grids, which can automatically reduce the amount of power generated by traditional power sources such as thermal power during the day when the amount of solar power is large, and automatically increase the share of power generated by traditional power sources when solar power cannot be generated at night. In this way, the smart grid can reach a balanced schedule.

In addition, it is worth noting that when constructing photovoltaic new energy projects, we do not need to build a scale as large as a gigawatt in remote areas such as the desert Gobi. First, the larger the scale of construction, the impact of grid-connected projects on the grid. The second is that these power stations are far away from the power-use side, and they must also consider long-distance transmission after they are completed. In view of this, I propose to do more distributed photovoltaic power generation projects below 10 megawatts combined with construction and the environment to learn about German photovoltaic applications.

The on-grid price policy still needs to be improved: On August 1, the National Development and Reform Commission issued the on-grid electricity price policy for solar photovoltaic power generation, and explicitly specified a unified benchmark on-grid tariff for unsolicited solar photovoltaic power generation projects. How do you rate this policy?

Zhao Feng: The PV on-grid price has been researched for several years and is finally being introduced. It is of great benefit to the industry. It can directly stimulate the domestic photovoltaic industry and allow it to achieve greater development.

The National Development and Reform Commission has set the on-grid tariff at 1.15 yuan and 1 yuan per degree. It has certain directionality and planning. After two or three years, the price of traditional energy such as coal-fired power will be almost equal to the cost of low-carbon emissions. Close to 1 yuan / degree, which will make the two prices gradually closer.

Although this clear electricity price is much lower than the price of feed-in tariffs in Germany and other European countries (the price of electricity supplied by these countries is generally 3-7 times the price of electricity), the National Development and Reform Commission has also considered its policy of introduction. The first is to avoid Too high to make the country's financial resources unbearable, followed by the promotion of photovoltaic power generation companies to quickly approach the price of traditional fossil fuels, and then promote the development of new energy.

Question: What are the shortcomings of this policy? What are your suggestions for this?

Zhao Feng: The policy cannot only determine the electricity prices for the past two years. It should also provide for the duration of the on-grid tariffs, that is, it should remain unchanged for a period of time, so that the entire industry can work toward the established direction. I propose to set the price of electricity for 5 to 10 years.

There is also a problem that the lighting resources conditions are not the same everywhere, and it is unfair to adopt a “one size fits all” approach to determining the price of electricity. It is recommended that provincial governments introduce corresponding supporting subsidies policies based on local lighting resources and the financial conditions of this level. For example, in the United States, the state government will also issue a subsidy policy while the federal government introduces basic policies. In this way, the development of local photovoltaic industry can get more policy support.

Question: Do you think that the subsidy funds required for this policy can be guaranteed in full?

Zhao Feng: Subsidy funds should be guaranteed. This fund can be extracted from the current collection of electricity charges, or it can be used to supplement the PV electricity price by subsidizing the carbon emission fee for buildings with relatively high energy consumption and new energy use ratios. The funding gap.
