Yiwu International Trade City in the three markets, the operating heads of households, there is a whole country's largest single roof solar photovoltaic power stations, the current state of the device is in standby, once per day through the examination and approval for the market to 4000 kwh electricity transmission. The operation of their business to fill the gaps in our province.
With the oil, coal and other energy prices to resume rising, solar energy photovoltaic industry more attention. March 23 this year, the Ministry of Finance, the Ministry of Construction of housing and urban and rural areas out "on accelerating the application of solar PV implementation of construction" and introduced "the application of solar PV building Interim Measures for the Administration of financial subsidies," the decision to conditionally construction carried out on the part of PV-per-watt maximum subsidy of 20 yuan. Recently reported the country's new energy to revitalize the forthcoming planning, which will focus on solar power development.
With the continuous development of economy and society, electricity has become a bottleneck restricting the development of Yiwu. Yiwu International Trade City in the construction of three solar roof designed device can not only ease the pressure of power shortage, and in line with the national advocate for the development of new clean renewable energy industry direction.
Yesterday, this reporter went to the Yiwu International Trade City, the fourth branch, Engineering Manager Wang introduced the solar photovoltaic system. Photovoltaic power station in the main by the PV array, DC Health Line box, centralized inverter, solar power and network control panel, communication systems composed of five parts, a total of 185 watts using 7000 components, 8 150 kW inverter, combination of steel roof construction eight regional installation, the realization of the solar photovoltaic power generation facilities and construction integration. The project was launched on September 14 last year to start the construction, the current through the completion of inspection, equipment and qualified network debugging, the normal test run.
The 1.29-megawatt solar photovoltaic power stations, the average annual power generation capacity of 1.57 million kwh, from 8 point grid access market. Its design life of 25 years, the product was 14.3% efficiency, 25 years can produce approximately 38,405,700 kwh of electricity, compared with thermal power, which is equivalent to saving about 14,978 tons of standard coal, 38,943 tons of carbon dioxide emission reduction, 359 tons of sulfur dioxide, 180 tons of dust, ash 3600 tons. Cost of the entire power generation system 53280000 yuan, 10.35 million yuan for the cost of a steel frame, with a total investment of 63.63 million yuan, with an average power-per-watt cost of building 50.
In the roof, the installation of a small room, imported from Germany, inverter, solar power and there are network control panel. Wang said that such a total of 8 devices can be used to control a computer, electricity, equipment operation can all be displayed on the computer, even around the world via the Internet can also be long-range real-time observation of system operation.
It is understood that the three Yiwu International Trade City market every day in the general electricity consumption of about 100,000 kwh, if hot, air conditioning, the daily electricity consumption of up to 150,000 kwh. Solar photovoltaic power station opened, can allow the market to get some added power consumption, reflects the greater significance of the environmental protection, green, energy-saving concept of construction, in order to clean and renewable energy to the popularity and application of a good model.
