9 meters high application of solar power system for solar street light

Solar power is influenced by season, day and night, rain or shine, but can be scattered, so it is suitable for families, respectively, to generate power, but also connected to the power supply network, make families in power when the rich can be sold to the electric power company, insufficient

although solar power by day or night, sunny days and rainy days, and the influence of the season, but it can be dispersed, therefore suitable for every family power alone, and should be connected to the power supply network, so that every household can sell it when power supply for electric power company, and in the power shortage can be purchased from electric power company. To achieve this technology is not difficult to solve, the key lies in the corresponding legal protection. At present, the United States, Japan and other developed countries have issued corresponding laws, in order to safeguard the interests of the family of solar power, and to encourage families to develop solar power. In April 1992, Japan has realized the solar power system and power company power grid interconnection. Some families have begun to install solar power equipment. Since 1994, the Japanese communication and industry implemented a two-thirds subsidy system for personal residence, used to buy solar power equipment. Need in the first year, 1000 households, 2000 need to 70000 households equipped with solar power equipment. According to Japanese authorities, estimates that if 80% of Japan's 21 million households are equipped with solar power generation equipment, Japan's 14% of the total electricity demand can be met. If factories, office buildings and other units are using solar power, solar power will account for 30% of the country's electricity - 40%. At present, the factors hindering the popularization of the solar power is the most important is the high cost. In order to meet the needs of ordinary families, 3 kw power generation system needs to be 6 million to 7 million yen, does not include installation fee. Relevant experts believe that solar power only when at least 1 million to 2 million yen to truly universal. Cost reduction is the key to improve the conversion efficiency, reduce the cost of solar cells. Recently, Texas instruments and SCE company announced that they have developed a new type of solar cells. Each cell consists of less than 1 mm in diameter of beads. They are intense and regularly distributed in the soft aluminum foil, like many eggs glued on the paper. In the area of 50 square centimeter, there are about 1700 such units. Characteristics of this new battery is that although the conversion efficiency is only 8% ndash; 10%, but the price is cheap. In addition, the aluminum foil backing soft and firm, can casually folded like a cloth and silk, durable, hanging in sunny places can power generation, is very convenient. It is said that the use of this new type of solar cells, power generation equipment is only 1 per watt of power. , $5 and $2 per kilowatt power generation cost can be reduced to 14 cents, completely can be equivalent to that of ordinary power plant generating capacity. By putting the battery in full sun roof and wall, every family can have 12000 degrees of electricity every year. 1 application area. Solar power: (by the user 1) 10 watts to 10 - 100 watts of small power sources used to power remote and areas, such as plateau, islands, pastoral areas, border posts and other military and civilian life electricity, such as lighting, TV, radio, etc. ； ( 2) 3 - 5 kw home roof grid-connected power generation system; ( 3) Photovoltaic water pump: solve without electricity deep Wells of drinking water and irrigation. 2. Transport sector, such as navigation lights, traffic/railway signal lamp, traffic sign warning/lamp, street light, high empty obstacle lights, road/railway wireless phone booth, unattended road power supply etc. 3. Communication/communication area: solar unattended microwave relay station, fiber optic cable maintenance station, radio/communication/paging power supply system; Photovoltaic systems, small rural carrier telephone communication machine, soldiers global positioning system (GPS) power supply, etc.
