China's photovoltaic power generation large area of abandoned light "


The actual development of photovoltaic power plants far more than the endurance of the grid, photovoltaic power generation step of wind power to follow the path of the abandoned light "phenomenon. The emergence of China's photovoltaic power generation "the disposable light" phenomenon, in addition to the inherent power generation unstable, immature technology, there are the following reasons.

In accordance with the "renewable energy and long-term development plan," By 2010, solar power generation capacity of 300,000 kilowatts, to reach 1.8 million kilowatts by 2020. Including in Tibet, Qinghai, Inner Mongolia, Xinjiang, Ningxia, Gansu, and Yunnan provinces (autonomous regions and municipalities), 2010, the construction of about 100,000 kilowatts of solar regulator photovoltaic power plants. 2011, the Qinghai region only new PV installed capacity reached 100 million kilowatts, to the 2010 plan targets 10 times. Grid construction planning had matched with long-term planning, the actual development is far more than the endurance of the grid, the photovoltaic power generation step of wind power followed the abandoned light "phenomenon.

Second, the lack of rational planning, resulting in power plants and power grid construction does not match the power station construction. 2011 new installed capacity, Qinghai, Ningxia, Jiangsu, Gansu, Xinjiang, living in the top five, their installed capacity accounted for 79% of the country's addition to the five provinces of Jiangsu outside, others are all less electricity demand relatively weak power grid construction provinces.

If you do not have a strong and smart grid to transport the electricity to other provinces, will inevitably lead to a waste of 
solar panels cost photovoltaic power generation. Countries had set the purchase price at the time, just consider the construction of the demonstration power plant through the introduction of fixed price, in the the sun resource-rich regions such as the Western, in order to stimulate the national PV applications. 

Therefore, causing a power shortage in the grid is relatively developed areas unconditional construction of photovoltaic 
monocrystalline solar panel power plants in the grid is relatively underdeveloped, fully powered areas, building too many power plants, resulting in areas of energy generation is not lack of electricity, lack of electricity The area could not send the embarrassing situation of electricity. Third, the lack of power station construction standards, grid access is difficult. 

The general period of use of the photovoltaic power plant in 20 years to 25 years, how to ensure that 25 years does not appear a major problem, which requires strict construction, installation and construction standards to constraints. The development of standards related to the future of power generation efficiency of photovoltaic power plants, service life and operational safety issues.

At present, China's strict specification standards has not yet formed, our standards are mostly concentrated in the field of battery components production, the basic construction of photovoltaic power plants, construction of GB. Compared to the component standards, the development of power plant building construction standards is much more complicated and complex factors to consider different parts of the hydrological, geological, sunlight and other natural conditions as well as the needs of the owners, but also consider the cost, it is difficult to unified.

It is understood that most of the photovoltaic power plant construction now, because there is no mandatory building GB, corporate construction are in accordance with their own ideas, as after completion, who acceptance testing, acceptance in accordance with what criteria was a problem. Overall, the photovoltaic field in China GB is imperfect, especially the lack of the detector acceptance criteria in a power plant is outstanding. Limit of photovoltaic power plants and has also become an important factor in the lack of standards, and thus the formation of a "the abandoned light" phenomenon current.
