Photovoltaic domestic market expansion three constraints
“21st Century”: the response to the the current PV crisis, the expansion of domestic market demand, has become the consensus of the industry. At the operational level, the domestic photovoltaic power generation market expansion which also faces constraints?
Fan will: in 2011, the domestic PV market installed capacity of 2.2 million kilowatts, only about 10% of all production of photovoltaic cells. Idle capacity, lack of external demand situation, only a significant expansion of domestic market demand, and is the fundamental way to ease the plight of the industry-wide.
Photovoltaic domestic market expansion, the first problem is the guiding ideology.
The photovoltaic power generation has continued the wind power, “the large-scale development of the high degree of concentration, long-distance, high-voltage carrier” idea, focusing on the development of the northwest desert region. Five provinces in the northwest PV installed capacity of 1.85 million kilowatts, accounting for more than 60% of the country, are mainly large-scale photovoltaic power plants. Northwest scenery is rich in resources, but space is limited local market consumer satisfaction, use the UHV distance transport to a thousand kilometers away, East China, Central China to use.
From the general law of energy use dispersed thin energy should be dispersed, if the concentration of the use of the consideration will be relatively large, wind power, solar power is a case in point. Europe and the United States to implement the “small-scale, distributed, low voltage, dispersed access system in place” mode, to meet most of the additional power demand. This model is a very small impact on the the grid main frequency and voltage parameters, more in line with wind power, photovoltaic power generation characteristics and the current level of technology.
Secondly, the subsidy is not ideal. Example, from 2009, started the Golden Sun Demonstration Project, three years of cumulative use of subsidies of about $ 10 billion of funds, strong support for the beleaguered PV companies. However, due to subsidies press reporting prior disbursement of funds, reduce the construction of an overstatement, components procurement shoddy phenomenon, the actual and the size of the network, power plant quality, especially the most critical power generation reporting level difficult to achieve. The role of subsidies in stimulating demand for PV products is less than ideal.
Finally, the lack of effective support for smart grid technologies. In developed countries, the smart microgrid development of distributed energy resources (wind, light, and other new energy and shale gas), in order to adapt to a variety of power supply in the form, the user side of the rise of the power grid construction and mode of operation, the international scientific community is called ” three industrial revolution. ” For example, the United States, Japan and Europe, implemented on a large scale rooftop PV program, many families during the day with a rooftop photovoltaic from inadequate power grid to buy electricity, formed millions of households, dotted photovoltaic use the pattern in addition to meet their own use, the excess electricity can be sold to the grid; . Abroad these distributed power point is also the main customers of the Chinese photovoltaic products, German, Italian rooftop PV last year were built 700,900 ten thousand kilowatts.
China in accordance with the Electricity Act 1995, “a power supply business district only to establish a supply business institutions. In addition to the other institutions of power companies may not sell electricity. This provision is clearly lagging behind the trend of the development of modern power. In recent years, the state authorities and the power grid enterprises focus on the development of the smart grid, the main goal is to meet the electricity to large-scale, centralized, the need for long-distance transport, how to micro-network, distributed energy and opening up has not been put on the agenda, to a large extent on restricting the use of photovoltaic products in China.
