Solar energy can be converted directly or indirectly into other forms of energy, such as heat and electricity. The major drawba
2、cks (problems, or issues to overcome) of solar energy are: (1) the intermittent and variable manner in which it arrives at the earths surface and, (2) the large area required to collect it at a useful rate. Solar energy is used for heating water for domestic use, space heating of buildings, drying a
3、gricultural products, and generating electrical energy. 盘郇锻溯膀诙颚嗦诖贲邓截羊In the 1830s, the British astronomer John Herschel used a solar collector box to cook food during an expedition to Africa. Now, people are trying to use the suns energy for lots of things. 诡厂篁蚊钐纂慵抛到钥厄酪哨Electric utilities are trying
4、 photovoltaics, a process by which solar energy is converted directly to electricity. Electricity can be produced directly from solar energy using photovoltaic devices or indirectly from steam generators using solar thermal collectors to heat a working fluid. Out of the 14 known solar electric gener
5、ating units operating in the US at the end of 2004, 10 of these are in California, and 4 in Arizona. No statistics are being collected on solar plants that produce less than 1 megawatt of electricity, so there may be smaller solar plants in a number of other states. 壕憋鄢辆窈偎距强钭茚异溜汐PHOTOVOLTAIC ENERGY似
6、垭籍轿眈禅穸珩谟芗菝荧蒲Photovoltaic energy is the conversion of sunlight into electricity through a photovoltaic (PVs) cell, commonly called a solar cell. A photovoltaic cell is a nonmechanical device usually made from silicon alloys. 死摹岘诘萑酲铛浍铣婴劭猛匏Sunlight is composed of photons, or particles of solar energy.
7、These photons contain various amounts of energy corresponding to the different wavelengths of the solar spectrum. When photons strike a photovoltaic cell, they may be reflected, pass right through, or be absorbed. Only the absorbed photons provide energy to generate electricity. When enough sunlight
8、 (energy) is absorbed by the material (a semiconductor), electrons are dislodged from the materials atoms. Special treatment of the material surface during manufacturing makes the front surface of the cell more receptive to free electrons, so the electrons naturally migrate to the surface.测思呛调胫被苎怄齄恰
9、乜蕴滚When the electrons leave their position, holes are formed. When many electrons, each carrying a negative charge, travel toward the front surface of the cell, the resulting imbalance of charge between the cells front and back surfaces creates a voltage potential like the negative and positive term
10、inals of a battery. When the two surfaces are connected through an external load, electricity flows. 辍稹呸燃甏迓储蝽变狳舯踟前The photovoltaic cell is the basic building block of a PV system. Individual cells can vary in size from about 1 cm (1/2 inch) to about 10 cm (4 inches) across. However, one cell only pr
11、oduces 1 or 2 watts, which isnt enough power for most applications. To increase power output, cells are electrically connected into a packaged weather-tight module. Modules can be further connected to form an array. The term array refers to the entire generating plant, whether it is made up of one o
12、r several thousand modules. As many modules as needed can be connected to form the array size (power output) needed. 醇生仰喇千辽琼攮每发惊栊猸The performance of a photovoltaic array is dependent upon sunlight. Climate conditions (e.g., clouds, fog) have a significant effect on the amount of solar energy receive
13、d by a PV array and, in turn, its performance. Most current technology photovoltaic modules are about 10 percent efficient in converting sunlight with further research being conducted to raise this efficiency to 20 percent. 坎麸昴锞兽椴睾獾嗾燧胤琉靶The pv cell was discovered in 1954 by Bell Telephone researcher
14、s examining the sensitivity of a properly prepared silicon wafer to sunlight. Beginning in the late 1950s, pvs were used to power U.S. space satellites. The success of PVs in space generated commercial applications for pv technology. The simplest photovoltaic systems power many of the small calculat
15、ors and wrist watches used everyday. More complicated systems provide electricity to pump water, power communications equipment, and even provide electricity to our homes. 釉伐岘懊单黾么你戟暇兵砹澄Photovoltaic conversion is useful for several reasons. Conversion from sunlight to electricity is direct, so that b
16、ulky mechanical generator systems are unnecessary. The modular characteristic of photovoltaic energy allows arrays to be installed quickly and in any size required or allowed. 凡毳嵩跟禚瑕轿徇诿淝斛鹏椿Also, the environmental impact of a photovoltaic system is minimal, requiring no water for system cooling and g
17、enerating no by-products. Photovoltaic cells, like batteries, generate direct current (DC) which is generally used for small loads (electronic equipment). When DC from photovoltaic cells is used for commercial applications or sold to electric utilities using the electric grid, it must be converted t
18、o alternating current (AC) using inverters, solid state devices that convert DC power to AC. Historically, pvs have been used at remote sites to provide electricity. However, a market for distributed generation from PVs may be developing with the unbundling of transmission and distribution costs due
19、 to electric deregulation. The siting of numerous small-scale generators in electric distribution feeders could improve the economics and reliability of the distribution system.燮颤晔蹰帛抵欹铈芩淬凉略徐SOLAR THERMAL HEAT艉钜住槔裎蝌辕忘莺稳抡着工The major applications of solar thermal energy at present are heating swimming
20、pools, heating water for domestic use, and space heating of buildings. For these purposes, the general practice is to use flat-plate solar-energy collectors with a fixed orientation (position). 鹞苍伫偈菩黔滇砹塬刹嘈骝迥Where space heating is the main consideration, the highest efficiency with a fixed flat-plate
21、 collector is obtained if it faces approximately south and slopes at an angle to the horizon equal to the latitude plus about 15 degrees. Solar collectors fall into two general categories: nonconcentrating and concentrating.In the nonconcentrating type, the collector area (i.e. the area that interce
22、pts the solar radiation) is the same as the absorber area (i.e., the area absorbing the radiation). 技呤箫末件瑛尥瘾薮空鹃斥佛In concentrating collectors, the area intercepting the solar radiation is greater, sometimes hundreds of times greater, than the absorber area. Where temperatures below about 200o F are s
23、ufficient, such as for space heating, flat-plate collectors of the nonconcentrating type are generally used. 笳久种孳婚瘪痔唪钽撂氇砚烂There are many flat-plate collector designs but generally all consist of (1) a flat-plate absorber, which intercepts and absorbs the solar energy, (2) a transparent cover(s) that
24、 allows solar energy to pass through but reduces heat loss from the absorber, (3) a heat-transport fluid (air or water) flowing through tubes to remove heat from the absorber, and (4) a heat insulating backing. 脯溆氦呷榧哒刿芗枢绨普夫鲚Solar space heating systems can be classified as passive or active. In passi
25、ve heating systems, the air is circulated past a solar heat surface(s) and through the building by convection (i.e. less dense warm air tends to rise while more dense cooler air moves downward) without the use of mechanical equipment. In active heating systems, fans and pumps are used to circulate t

The collector tracks the sun a
30、long one axis from east to west during the day to ensure that the sun is continuously focused on the receiver. Because of its parabolic shape, a trough can focus the sun at 30 to 100 times its normal intensity (concentration ratio) on a receiver pipe located along the focal line of the trough, achie
31、ving operating temperatures over 400 degrees Celcius.不艮霍驵彘缰锭尾相衿面蹦甍A collector field consists of a large field of single-axis tracking parabolic trough collectors. The solar field is modular in nature and is composed of many parallel rows of solar collectors aligned on a north-south horizontal axis.
32、A working (heat transfer) fluid is heated as it circulates through the receivers and returns to a series of heat exchangers at a central location where the fluid is used to generate high-pressure superheated steam. The steam is then fed to a conventional steam turbine/generator to produce electricit
33、y. After the working fluid passes through the heat exchangers, the cooled fluid is recirculated through the solar field. The plant is usually designed to operate at full rated power using solar energy alone, given sufficient solar energy. However, all plants are hybrid solar/fossil plants that have

This system uses hundreds to thousands of flat sun-tracking mirrors called heliostats to reflect and concentrate the suns energy onto a central receiv
39、er tower. The energy can be concentrated as much as 1,500 times that of the energy coming in from the sun. Energy losses from thermal-energy transport are minimized as solar energy is being directly transferred by reflection from the heliostats to a single receiver, rather than being moved through a
40、 transfer medium to one central location, as with parabolic troughs. Power towers must be large to be economical. This is a promising technology for large-scale grid-connected power plants. Though power towers are in the early stages of development compared with parabolic trough technology, a number
