Distributed photovoltaic equipment to the Chinese people "in their own power generation"

Xinhua News Agency, Changchun, June 8 (Xinhua Meng Yiqi) 5 pieces of 100 watts of photovoltaic power generation board in the roof line lined up, neatly distributed, inverter digital flashing. Changchun City, northeast China, an ordinary citizen home, the reporter saw the residents Li Zhu built a distributed photovoltaic power station, opened a self-produced energy-saving life.


In the context of an increasingly scarce energy, the world to develop photovoltaic industry. As the majority of areas in China, sunshine conditions are better, the potential for the development and utilization of solar energy resources, so the Chinese government to give full support to the photovoltaic industry.


Although Li has more than 40 years old, but like to touch new things. As early as 2011, he tried to use small-scale distributed photovoltaic power generation, in 2013 began a comprehensive spontaneous use, and in August 2013 from the grid.


Li Zong calculations: PV power plant annual power generation 6000 kilowatt hours, the subsidy standard 0.42 yuan / kWh, after deducting 17% VAT can get 2091.6 yuan; one of its own electricity 900 kilowatt hours a year, the remaining 5100 kilowatts When the grid by the power supply enterprises by 0.3974 yuan / kWh acquisition, available 2026.74 yuan, a total of 4118.34 yuan.


"The use of photovoltaic power generation voltage stability, in the self-sufficient power to enjoy the state subsidies at the same time, but also" selling electricity ", especially cost-effective." Lee said.


In May this year, Chongqing City, the birth of the first 6 kilowatt-hour distributed photovoltaic power generation projects, the project investment of nearly 7 million; June 4 is the Jiangsu Province, "the sale of electricity, Electricity first person "Zhu Qijie grid power generation and the first anniversary, so far he has 6,000 kilowatts of electricity, to meet their own household electricity demand, but also profit more than 4,000 yuan.


It is understood that the family of distributed photovoltaic power generation has many advantages: make full use of solar energy resources, without mining, transportation; solar energy is clean energy, the use of solar power to reduce coal combustion at the same time, reduce carbon dust, carbon dioxide, sulfur dioxide and other pollutants emission.


Although the development of distributed photovoltaic in China is not early, but the pace of development is gradually accelerating. According to the National Energy Board website published data show that by the end of 2013, Chinas new distributed photovoltaic power generation capacity of 800,000 kilowatts, the cumulative grid-connected distributed photovoltaic power generation capacity of 3.1 million kilowatts.


However, distributed photovoltaic power generation in the promotion, some problems need to be resolved. State Power Grid Jilin Province Electric Power Co., Ltd. Marketing Special Engineer Gao Zhenhua that the construction of distributed photovoltaic power generation costs are high, long payback period, limiting the enthusiasm of power generation users.


Li Zhujia Although each year through the power generation and "selling electricity" can yield about 4120 yuan per year also save their own electricity 472 yuan; but the purchase of photovoltaic power panels, grid inverter, bracket and other investment costs nearly 50,000 yuan, without considering the maintenance Equipment, the investment recovery period is about 11 years.


Some areas in the development of distributed photovoltaic power generation will be subject to the size of the construction site constraints, can not build a larger capacity of the project. To Lizhujia, for example, home 5000 watts of photovoltaic power plant covers an area of 33 square meters.


"Chinas annual increase in construction area, a new building and distributed photovoltaic power generation how to better integrate, is the government and photovoltaic equipment manufacturers currently need to study the subject." Gao Zhenhua said
