what exactly is solar powered energy?
90843
Light consists, at least in part of photons.  Photons excite photoelectric cells.  Excitation in photoelectric cells induce electric current.  Electric current is charges and is stored in storage battery or otherwise put into electric grid for immediate use.

"The Sun has been producing solar energy, or heat, since about the same time the Earth was formed 4.6 billion years ago. Solar energy comes from deep within the core of the Sun. There, the temperature is about 27 million degrees Fahrenheit, and the pressure is about 340 billion times the Earth's pressure at sea level. This creates nuclear reactions that release heat energy through convection (http://www.solarviews.com/eng/edu/convect.htm). Five million tons of energy are released from the Sun's core every second. This is the energy that allows life on earth to exist! Scientists predict the Sun will last another five billion years before it collapses into a white dwarf, a star at the end of its burning stage."

Solar Energy\n* inexpensive (free, only maintenance costs of the device)\n* does not work well on cloudy days or days when the sprayers fly, or does not work at all (needs electric back up)\n* Active solar: e.g. the heat is forced down from the ceiling, gathered by voltaic cells (solar panels). \n* Passive solar, a wall within a glass enclosure is painted black and absorbs the heat (green house effect maximized). Warm air can blow through a hole in the upper black wall into the room behind the black wall.\n* Solar energy prevents pollution.\n* Solar energy does not drain the oil reserves of the earth.\n* There are solar warm water heaters, heaters and cookers.\n* Solar cookers and passive solar can be self-made.\n* Solar energy is used simply by opening the curtains and letting the sun shine on tile floor.\n\nLet the sun shine and the skies again be blue!\nCordially, India.Magica

Solar Power harnesses the energy of the sun to turn water into high pressure steam. The sun gives panels which heat the water kinetic energy to affect the interaction energy of the water (like how you get a sunburn). The steam rotates a turbine to generate power.

The Sun produces energy through a process called "nuclear fusion." This is the same process that happens in a hydrogen bomb. The Sun converts hydrogen into helium, and that conversion process releases energy, mostly in the form of heat. The Sun "burns" about 600-million tons of hydrogen every second.

A solar cell (or a "photovoltaic" cell) is a semiconductor device that converts photons from the sun (solar light) into electricity. In general a solar cell that includes both solar and non-solar sources of light (such as photons from incandescent bulbs) is termed a photovoltaic cell. Fundamentally, the device needs to fulfill only two functions: photogeneration of charge carriers (electrons and holes) in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity. This conversion is called the photovoltaic effect, and the field of research related to solar cells is known as photovoltaics.\n\nAlso check this link, this is from NASA http://science.nasa.gov/headlines/y2002/solarcells.htm

Solar energy (from solar panels)  converts sunlight into electricity. Solar arrays (massive groups of solar panels) can be used to produce energy on an industrial scale, but the average solar panel is still expensive and produces very little power.  However these solar arrays can be attached to the power grid like a normal power plant.  \n   Coal  fired power plants are currently the primary fuel used to produce electricity in the US.  There are also a  very few oil/gas plants used to produce power.      Solar panels can be placed on very light weight vehicles (like bikes) as a primary power source.  However since the power produced from a solar panel is pretty small,  you will never see a viable commercial solar powered SUV in the next 15 years.

While the above is true, don't give up. U can still get power from the sun to power your computer.\nAlso, there are many prototypes in the works.\n\nMicro-Star unveils solar-powered notebook computer:\n \nThursday, January 12, 2006 \n\nA Taiwanese company has developed a solar-power notebook computer to save computer users the trouble of charging batteries by plugging them in, the company said yesterday. \n\nMicro-Star International Co said it spent a year to develop the first-generation solar notebook computer, Solar NB, and is now developing the second-generation Solar NB. \n\n"Solar NB is a notebook computer with a solar panel on its top. The first-generation Solar NB can operate on solar light power for half an hour but it takes the solar panel half an hour to collect that much power," Micro-Star International's marketing manager Chen Chien-hung said. \n\n"For the second-generation Solar NB, we will use satellite solar power which is more effective but also more expensive," Chen said. \n\nThe 12-inch first-generation Solar NB costs NT$55,000 (US$1,700). The second-generation Solar NB will cost NT$80,000 and is expected to be able to operate on light power for at least four hours. \n\nChen said that although Solar NB can be used outdoors, the main purpose of developing Solar NB is not for outdoor use, but for indoor use, and the solar panel does not collect solar power, but light power. \n\n"We want to allow people to use notebook computers when they travel in an aircraft or train, either by relying entirely on light power or using both light power and the battery when the light in the plane or train is dim," he said. \n\nMicro-Star International unveiled a pair of Solar NBs at the 2006 International Consumer Electronics Show last week in Las Vegas, but will not market it until the product is more mature. \n\n \nhttp://www.partsonsale.com/desktopcompsol.html\n\nhttp://www.solarpower.org/art4.html

http://www.darvill.clara.net/altenerg/solar.htm\n\nThis is a favorite source of future energy for many people, comforted by the thought that it is unlimited. But, quite the contrary is true. The Sun will exist for a long time, but at any given place on the Earth's surface the amount of sunlight received is limited--only so much is received. And at night, or with overcast skies, or in high latitudes where winter days are short and for months there may be no daylight at all, the sunlight received is very limited at times. Direct conversion of sunlight to electricity by solar cells is a promising field, but the amount of electricity that can be generated by that method is not great compared with demand. The conversion efficiency is low, about 12 percent with present technology.\n\nSolar energy in quantity requires huge installations. It has been estimated that an area of 60 square miles in relatively clear central Oregon would have to be covered with solar cells in order to meet the present electric needs of that State. About 10% of the cells have to be replaced each year. But the big problem is how to store significant amounts of electricity when the Sun is not available to produce it. That problem remains unsolved. The statement that "solar energy will not make next century's electricity" is probably right. And the end product is electricity--a very limited replacement for oil.

You can store it in batteries and it lasts as long as the batteries last.\n\nThe sun produces a huge amount of energy every day (173 millions of billions Watts). The amount we receive generates wind (converted into electricity through windmills), heat, photosynthesis of plants and trees and 1.37kw of energy per square metre. This energy can be harnessed by PV cells and converted into electricity. In fact, less than 1% of our planet’s desert areas would generate all the electricity we need if it was covered with PV panels.\nGenerating electricity this way is quite simple: light hits a cell made of a thin layer of silicium over a metal support which generates electrons. The motion of these electrons generates current. PV cells are assembled in panels, generating up to 100w/h of DC power (14v approximately). These panels are connected to a regulator, which controls the electricity production, sends some to appliances, some to battery storage and dumps any excess. PV panels generate electricity when subjected to sunlight. This means they do not produce at night. This is why most systems store electricity in batteries.\n \nHOUSING APPLICATIONS\nA modern house does not require a lot of electricity and it does not seem very efficient to burn diminishing fossil resources in huge plants located far away and then transport this electricity over hundreds of kilometers to houses. By having a few PV panels on the roof, any ordinary house can generate its electrical needs; this power can be supplied in DC (for halogen lighting for example) and AC (220V) through an inverter to power standard appliances.\n \nA house connected to the grid can then sell electricity by day and buy some back at night.\nAn independent house generates all its needs by storing electricity in battery banks. In windy areas, a windmill can be a very good complement to PV systems.\n \nPV systems do not require fuel, have no moving parts that can wear, require virtually no maintenance and last for a very long time (some PV systems have a 30 years warranty).\n \nINDUSTRIAL APPLICATIONS\nThey constitute the bulk of the applications today, for remote lighting, transmitters, satellites in space, etc. Industrial buildings could also produce part of their needs through PV.\n \nCOST MATTERS\nIs PV technology expensive? Prices are now going down and make it ever more competitive. PV systems last a very long time and over say 50 years, they should become extremely competitive.\nThe cost of fossil fuels is expected to increase over the next 20 years. Furthermore, fossil fuel generators require heavy maintenance. Another aspect to take in account is the pollution they generate: this has a heavy cost in terms of global warming, poor air quality, health problems and logistic costs (transport of fossil fuels, electricity on high power lines and their waste), not to mention collateral damage such as oil slicks, Chernobyl type accidents, respiratory diseases, chemical runoffs and other nasty results.
