A lengthy time, folks have been working onerous on the usage of solar energy. Received by our planet of the photo voltaic energy, only the floor of the Sun issued all about energy, the energy equivalent of the world’s total energy necessities of the 3-4 million-fold, is inexhaustible, and the non – exhaust. Secondly, the space will not be divided into days and nights and seasons, no clouds and shadows, very steady radiation power in.
Thus generating system than the ground relatively simple, but in the absence of weight, excessive vacuum environment of the universe, the strength of apparatus components isn’t too excessive demands. Moreover, solar power and oil, coal and other fossil fuels, would not lead to the “greenhouse effect” and world climate change, is not going to cause environmental pollution. For this reason, using solar vitality (laptop battery) are of great importance in many countries, we are in a race to develop new technologies and photoelectric photoelectric new materials to expand the utilization of solar vitality applications.
Especially prior to now 10 years, in growing oil manufacturing to the underside and the deteriorating ecological environment of these two crises together with the attack, we are looking forward to an increasing number of “solar age” to come. From energy generation, heating, water provide to a variety of solar energy plants, and their use is very extensive, and in some areas, the usage of solar power has entered the sensible stage.
From 1974 to 1997, the United States and Japan and other developed countries silicon photovoltaic energy generation costs by an order of magnitude: from 50 U.S. dollars per watt down to five U.S. dollars latitude D620 battery. Since then a lot of the world experts imagine that solar energy station to station with the normal (mainly the ability plant) compared with the competitiveness of the economy, there’s still a long solution to go in the same – to reduce the cost of re-do an order of magnitude.
At present, the United States and other countries make use of solar pond constructed by the project loads of power. The banks within the Dead Sea in 1979 to build a 7000 sq. meters of the experimental photo voltaic pond for a heat generating 150 kilowatts. The United States plans to 8.3 % of its Salt Lake space (about 8000 sq. kilometers) solar pond constructed for the 600-megawatt generating units of heating.
In June this year, Armenia Radio Physics and dell experts announced that the mountain within the country has begun the development of its “The first experimental prototype” solar power plant industries. The turbines used in power stations is just not new, but life has expired and removed from the helicopter to the turbine installed capacity of only 100 kilowatts, however the electricity cost of 0.5 cents / kilowatt-hour, efficiency as excessive as 40% -50 %.
Russian scholars in the study of solar pond has additionally made outstanding progress. A company to develop solar energy and water jet propulsion thrusters cool mission with a mix of photo voltaic pond, photo voltaic pond to the tank with ice and other facilities designed for the new solar pond farmers. According to this design, a 6-8 particular person households to build a photo voltaic pond of 70 square meters, 100 square meters will be able to meet their housing needs of the whole year of electricity.
