Shenyang residents are expected to be solar-powered


Not only save money, and energy conservation and environmental protection, ordinary families simply by means of the sun will be able to solve the daily electricity. This reporter recently learned from the first China Shenyang International Photovoltaic building energy efficiency forum. It is reported that the province first civilian residential solar photovoltaic equipment has become the first pilot residential building in Shenyang, Shenyang Institute of Engineering pilot the use of solar-powered University, carried the University City Shenbei PV line transformation next year will. Solar power supply is expected to enter the home of ordinary people.

Enterprises moving ahead of the first test for the solar power supply into the family do to prepare a few days ago, the reporter saw a row of blue solar photovoltaic panels on the roof of Liaoning solar panel Applications Ltd, in between the rows of photovoltaic panels, also one can measure the light intensity of the instrument.

The staff told reporters that if normal weather, abundant sunshine, the electricity generated by the power stations fully meet the company electricity in case of power overload or cloudy rain and poor lighting conditions, supplemented by the national power grid.

The reporter also found that each row of photovoltaic panels placed angle is not the same. Staff, said that the purpose of this design is in order to facilitate the photovoltaic panels to better accept the sun light, because the seasons sunlight irradiation angle is not the same, it should be appropriate to adjust the angle of the photovoltaic panels, winter slightly steeper angle point summer angle slightly flat point, generating capacity increased by 40%.

It is understood that, in the province, the solar controller-powered more used in business. Three months ago, the Northeast is the largest class of commercial office rooftop PV power plant projects in the Hunnan New District of Shenyang International Software Park completed and put into use. 20 enterprises of the software park office lighting and other electrical achieve full solar energy supply. Enterprises in the electricity on the installation of solar power supply system are the two legs to walk priority use of solar power, followed by the national power grid.

The use of solar photovoltaic power generation project, not only the obvious economic benefits, environmental benefits are more promising. Shenyang International Software Park, the 20 companies, for example, 1,680,000 kWh of electricity per year to use, if you use the national grid electricity, according to the Shenyang peak tariff of 1.1 yuan / kWh tariff for each year of 1.848 million yuan.

The use of solar power per kilowatt of electricity than the peak tariff Province 0.22 yuan, the annual electricity savings of 369,000 yuan, and the annual energy conservation, carbon trading income 157,500 yuan. 20 companies each year to save costs 526,500 yuan, the number of reducing greenhouse gas emissions will reach 1795.92 tons. The enterprise's first try for the solar energy into the family laid the foundation.

The government and the District Court in Shenyang, the reporter is more intuitive feel the effect of the solar-powered ". Within the government and the District Court roof, almost all stood a few blue photovoltaic panels. It is understood that this is an important part of the solar photovoltaic equipment, used to absorb solar energy.

The conversion of charge controller energy into electrical energy, a controller will need to go through voltage becomes 220 volts can be used. A 100-watt board area of ​​about 0.8 square meters, one hour can generate 100 watts of power. In Shenyang, daily exposure time of about five hours, a board can generate electricity to 0.5 degrees.

Today, the district's public lighting using solar-powered year. Into the underground car park, the reporter found that here is not like any other car park is 24 hours long light. After a supply line transformation, there is only a few lamp has been lit, the rest of the lights are infrared sensors, when the heating element (such as people or cars) passing lights automatically light up after turn off automatically. In addition to the underground car park district within the corridor lights set to adopt a similar model. Thus, on the basis of solar-powered, more energy-efficient.
