Topic Background:
February 26, International Trade City in four districts of rooftop solar photovoltaic power generation system formally and net electricity generation, four blocks of the business to some bits and channel pure light of the "low-carbon light."
Low-carbon, now in the entire international community, has become a hot term, all countries are doing everything possible to put large number of studies in this field, the strength and financial resources, the promotion and development of this sunrise industry of the 21st century. International Trade City of photovoltaic power generation projects, because sometimes moving, timely construction continued in the four districts in the next project, showing the Yiwu "pioneers" of the vision and courage.
Ma rooftop PV project is an innovative
Moderator: photovoltaic project is implemented in a year where, why should the roof at the International Trade City, "top" on such a new project?
Ma Weizhong: Four area rooftop solar power projects, should be on in 2008. International Trade City was the construction of four districts are in full swing to start construction very nervous, because rush schedule, but that year the weather conditions are not very good. Therefore, the surrounding areas in the building are the buckle is very tight, the whole immersed in a safe workplace on the basis of "overtime" state. Project planning, people of "low carbon" or strange, but solar PV is also still a "new fad." After a discussion later in the argument, it was decided in the four districts in the top for innovation, and scientific use of roof space.
That would add a "may open the sunroof," "the use of rainwater harvesting," "solar photovoltaic power generation" and other projects.
Wang Kun: It is an innovative rooftop photovoltaic power generation project was launched across the country, or very rare, and our single large area. Because it is new, domestic exploration is still in a trial stage of development, many areas there is no matching, and many ingredients are also developing improvements. So, at the time on such a project was determined, not easy.
Wang Hui-ping: Now looking back, on which a project is really not easy, "move faster than others," It takes courage and boldness. Recently, the rooftop solar photovoltaic power generation system to obtain approval of provincial committee through a letter, but a formal grid, and this is very worthy of celebration. "Low-carbon" economy is a direction, the State more and more attention, we could a few years ago, on the photovoltaic power generation project, but also Taiwan's first single large-capacity solar photovoltaic power generation system, there is a bit the first to "eat crab "flavor, point to very meaningful.
Greatest advantage of solar photovoltaic power generation is clean and green
Moderator: What are the benefits of solar photovoltaic power generation?
Ma Weizhong: The greatest advantage of solar photovoltaic power generation is clean and green, is the real part of the national policy in favor of low-carbon economic projects. Although this project we have total power generation capacity relative to international trade and business city in terms of the overall electricity consumption could only be a supplement, but in the current area has been very good in terms of monomer, and the social and environmental benefit is obvious.
We are now photovoltaic system design life of 25 years, with a thermal power compared to the equivalent of saving a grand total lifetime of 14,978.2 tons of standard coal. The conversion could be about 38,943 tons of carbon dioxide emissions of sulfur dioxide of about 359.5 tons and 104.8 tons of nitrogen oxides.
Wang Hui-Ping: This is indeed a "green roof" on the city's energy-saving emission reduction work is a good example and contribution. Moreover, the current international energy development and utilization of new projects, with a "carbon" trading market, development and utilization of new energy sources can also generate substantial amounts of "carbon" foreign exchange. The current market conditions is 10 euro / ton, that is, compared with traditional power generation, for every 1 ton to reduce carbon dioxide emissions could be 10 euros in exchange for foreign currency. On our solar photovoltaic systems, according to current prices is estimated that 38,943 tons run the 25-year reduction of carbon dioxide, can be earned 389.43 thousand euros. Now,
National Development and Reform Commission has set up a special office in charge of the "carbon" trading.
International Trade City of photovoltaic power generation is a point
Moderator: International Trade City, how the composition of photovoltaic power generation system and the grid after the operation like? It would give the city a low carbon economy and energy savings to bring the work of what kind of positive impact?
Wang Kun: International Trade City, a total installed capacity of solar photovoltaic power generation system is 1.295 MW, the system uses to generate electricity grid operation mode to produce electricity for internal consumption of buildings. The whole "green roof" project, were installed in eight regions, constitute the eight sub-systems, the roof of photovoltaic arrays each region corresponds to a control room, each subsystem the control room to install a solar power inverter and one and network control panel, the nearest incorporated into an independent and outlets for local load power. Project by 7000 poly-silicon photovoltaic array, inverter, control, detection systems and power distribution systems, four major composition,
A total investment of nearly 7,000 million, the system embodied in the design aesthetics, advanced, maturity and stability.
The system has been a year of preparation, in the electricity sector with the active support on February 26 this year, an official in the Grid. From the grid after the operation situation, the effect is still very evident. Although the rainy weather these past few days mostly, but as long as there is light, the clouds are not thick, the system will generate electricity. Every day, our recent track record of generating conditions are. February 27 overcast cloudy weather, power generation, 1949.5 kwh; February 28 sunny days, 7 regional work, power generation, 4463.5 kwh, if the eight regional full-power generation capacity should be more than 5100 kwh.
Ma Weizhong: look at the numbers, the system operating normally. We have set up special teams, and groups of the power generation system for effective management and maintenance, and improve the environment according to the actual conditions and equipment, in accordance with the guidance of the electricity sector to implement the scientific operations. Try to make clean energy projects and have completed our city, "low-carbon" construction in the "pioneer" project, resulting in a variety of "effectiveness." Our project has taken the lead in specific implementation process met a number of gaps, but with the advancement of national policy, related technologies will become more mature, the cost will be reduced, this industry will be growing in volume.
Wang Hui-ping: International Trade City of photovoltaic power generation, is a point that it our low-carbon economic development and energy-saving emission reduction work is a positive advance. In recent years, the city's energy consumption has achieved good results. "Eleventh Five-Year" four years before the incomplete estimates, unit GDP energy consumption fell by 17.6% cumulative take the forefront in the province, has been repeatedly commended the provincial government.
Reduce the "carbon" emissions to jointly cope with global warming has become a world consensus. On the current science and technology is concerned, it is necessary to sustain the development of industrial economy, but also reduce the "carbon" emissions, and an important way is to increase the development and utilization of solar energy and other new energy sources to replace oil, coal and other traditional energy sources. In this regard, all levels of government has increased its support for new energy development and utilization. The city as a world-renowned commodity distribution center, 126, issued late last year to document clearly on the new energy development projects and key support, "Equipment investment of 300 million yuan through the accreditation given to investment in equipment 20% of the amount of subsidy" .
International Trade City, the operation of photovoltaic power generation system is bound to deepen the city's low-carbon economy, the community awareness, and inspire and guide the development of more businesses have taken "low carbon" economic pace.
Name Resolution
Solar photovoltaic
Use of solar energy can be divided into light and heat and photovoltaic two areas. Solar light and heat is converted directly through the physical heat, we are the most common solar water heater is a good example. Optoelectronics, also known as photovoltaic power generation, is the use of solar photovoltaic effect of semiconductor materials, will convert solar energy directly into electrical energy.
Solar photovoltaic grid-independent operation and run in two ways. Stand-alone photovoltaic power generation systems require batteries as energy storage devices, mainly applied to non-grid in remote areas and scattered population areas, the relatively high cost of the entire system; in the area by public power, photovoltaic power generation system and grid connection and network operation, eliminating the need for batteries, not only can greatly reduce costs, but also has a higher power generation efficiency and better environmental performance. At present, solar photovoltaic technology is maturing, is the most desired features of sustainable development of renewable energy technologies. Globally
Many countries are seeking to develop solar photovoltaic power generation, which has been the forefront of Germany and Japan, China is also accelerating renewable energy development and utilization. Energy experts believe that China's solar energy resource is rich and widely distributed, and the development of solar photovoltaic power generation potential.
Solar photovoltaic cells used to convert the sun's light energy directly into electrical energy. Is currently being studied around the world are mainly monocrystalline silicon photovoltaic cells, polycrystalline silicon, amorphous silicon photovoltaic cells. In the energy conversion efficiency and service life of a comprehensive performance, monocrystalline silicon and polycrystalline silicon cells is better than amorphous silicon cells. Slightly lower than the conversion efficiency of polycrystalline silicon, but the price is relatively cheap. In addition, there are other types of photovoltaic cells.
