Application of solar power generation system solar street light-litelsolar manufacturer

Although solar power generation is affected by day and night, rain, and season, it can be carried out in a decentralized manner, so it is suitable for each household to generate electricity separately, and it must be connected to the power supply network, so that each household can sell it to the power supply when the electricity is rich. The power company can buy from the power company when it is in short supply. The technology to achieve this is not difficult to solve, the key is to have corresponding legal protection. At present, developed countries such as the United States and Japan have formulated corresponding laws to ensure the interests of households in solar power generation and encourage households to generate solar power. In April 1992, Japan has realized the interconnection of the solar power generation system with the power grid of the power company, and some households have begun to install solar power generation equipment. Since 1994, the Ministry of International Trade and Industry of Japan has implemented a system of subsidizing two-thirds of the cost of purchasing solar power generation equipment for individual residences. It is required that 1,000 households in the first year and 70,000 households in 2000 be equipped with solar power generation equipment. It is estimated by relevant Japanese departments that if 80% of the 21 million individual houses in Japan are equipped with solar power generation equipment, they can meet 14% of the country's total electricity demand. It will account for 30%-40% of the national electricity. The main factor hindering the popularization of solar power generation is the high cost. In order to meet the 3-kilowatt power generation system for general household electricity needs, it costs 6 million to 7 million yen, not including installation labor. Relevant experts believe that solar power generation can be truly popularized only when it falls to at least 1 million to 2 million yen. The key to reducing costs is that solar cells improve conversion efficiency and reduce costs. Not long ago, Texas Instruments and SCE announced that they have developed a new solar cell, each unit is a small bead less than 1 mm in diameter, they are densely and regularly distributed on the soft aluminum foil, like many silkworms The egg clings to the paper. There are 1,700 of these units spread over an area of u200bu200babout 50 square centimeters. The characteristic of this new battery is that although the conversion efficiency is only 8%-10%, it is cheap. In addition, the aluminum foil backing is soft and strong, which can be folded at will like a cloth and is durable. It is very convenient to hang it in the sunny place to generate electricity. Allegedly, the use of this new solar cells, equipment per watt of power generation capacity as long as 1.5 to 2 US dollars, and the cost of electricity per kilowatt hour can also be reduced to about 14 cents, can compete with the electricity produced by ordinary power plants. Every family hangs this kind of battery on the sunny roof and wall, and can get 1,000 or 2,000 kWh of electricity every year. Application field 1.
