South Korea Sogang University Built The First Operation Of The Solar Power Station

South Korea's Sogang University, construction of solar power plants operating - Wen-solar power stations and the recent completion of the ceremony was held. It is said that the University of operation of the solar power station built in South Korea is the first. The power station built in South Korea's North Gyeongsang Province, Wen Qing City.

Wen-solar power stations, covering about 10,000 square meters, has two sets of solar power generation equipment, power generation size of about 1,000 kilowatts, for the 1500 average household electricity consumption. Power station construction with a total investment of 8 billion won. Sogang University is expected, so the school can benefit from each of 1 billion won. As an incentive the development of clean energy and conservation of oil policy, the Government will row 15 year to purchase electricity from solar energy power station.

IBM's Convex Lens Concentrating Solar Power System

IBM's use of Convex Lens a condenser and then be exposed to the solar panel to increase the intensity of sunlight, thereby increasing the generating capacity of solar cells. Through this method, the success of the 230 watts of solar energy will be transformed into 70 watts of electricity, conversion efficiency of traditional solar system is about five times.

Many people may be worried about the excessive solar heat will melt. Do not worry, IBM in the system of integrated temperature control system. In general through the PV solar cell panel joined the liquid metal cooling system. When the temperature rises rapidly, can be as high as 1,600 degrees lower the temperature to 85 degrees, so as to avoid burn solar cells. IBM plans to sell the technology to solar energy enterprises, to help them improve product efficiency.

China's Solar Thermal Power Generation Technologies And System Model

Solar thermal power generation at the power plant model.

May 17 morning, "jointly building an innovation-oriented country" as the theme of the 2008 science and technology activities week, the China Science and Technology Museum opened.

China's Ministry of Science and Technology in the "11th Five-Year" Plan period to establish 863 key projects - "solar thermal power generation technologies and system model", the establishment of MWe-class solar thermal power generation experimental demonstration tower system. Beijing City Power Station was built in Yanqing County, Badaling town of Tingri-field a total area of 10,000 square meters, 8.83 MW power collector. Solar tower 100 meters high. Tower power station using "light - heat - electricity" generation, through the 10,000 square meters Tingri will mirror the sun to heat accumulation on the solar energy absorption tower, a steam turbine operation to promote power generation. Yanqing in accordance with the direct solar radiation of local resources, the power station, power generation capacity up to about 1.95 million, compared to traditional fire power plants, annual savings of 663 tons of standard coal and reduce emissions CO2 2336.6 tons, SO2 17.5 tons, NOx 7.8 tons. 136.3 tons of dust particles.
