what is solar power?

Answer 1

The energy in fossil fuels (e.g., coal and oil) and other organic fuels (e.g., wood) is derived from solar energy. Difficulties with these fuels have led to the invention of devices that directly convert solar energy into usable forms of energy, such as electricity. Solar batteries, which operate on the principle that light falling on photosensitive substances causes a flow of electricity, play an important part in space satellites and, as they become more efficient, are finding increasing use on the earth (see solar cell). Thermoelectric generators convert the heat generated by solar energy directly into electricity (see thermoelectricity). Several projects have produced electricity on a large scale by using the solar energy available in desert areas. In one system, large numbers of solar batteries generate electricity for Coconut Island, off the coast of Australia. In another, oil flows through pipes that are set in reflecting parabolic troughs that can trap the heat from sunlight falling on them. The heat from the oil is then converted into electricity (see power, electric). Heat from the sun is used in air-drying a variety of materials and in producing salt by the evaporation of seawater. Solar heating systems can supply heat and hot water for domestic use; heat collected in special plates on the roof of a house is stored in rocks or water held in a large container. Such systems, however, usually require a conventional heater to supplement them. Solar stoves, which focus the sun's heat directly, are employed in regions where there is much perennial sunlight.

You already have some great answers. I'd just add that the sun is virtually the sole the source of energy for our solar system. It naturally supplies the power/heat that helps our plants to grow, helps us to live here, etc. etc.
In terms of renewable energy sources solar power is being used in three or four different ways that I know of at the moment.
Passive solar power is utilising the heat from the sun to increase your home's energy efficiency. This is prodominently done through building in large south facing windows and sometimes includes shades to cool the house during hotter weather.
Thermal solar power is where water is heated through solar panels that consist of pipes through which the water flows. People are apparently using this alot for swimming pools and it can also be used for homes to bring up the temperature of the water before using the usual heating system.
Photovoltaic solar panels are panels made up of solar cells which convert the sun's heat to electricity. Currently photovoltaics are fairly popular though not terribly efficient, (hydropower is the most efficient form of renewable energy), Research is ongoing and it's looking very possible to increase efficiency. This form of solar power, if used in conjunction with other means, such as a small wind turbine, can certainly go a long way to producing enough electricity for a home.
Solar cookers are great - they're used in desert countries, and are basically reflective material shaped in a bowl in which food can be placed and cooked. They help reduce carbon emmissions and respiratory diseases; as the common fuel prior to the solar cookers would have been open wood fires. They also free up time and labour in having to collect the fuel.
I've just remembered another that is used in countries that have no access to clean water - by filling bottles with water and placing on a dark surface the heat from the sun sterilises the water. Prior to this all water had been boiled, and apparently people are now noticing much reduced stomach ailments.

Answer 3

The term solar power is used to describe a number of methods of harnessing energy from the light of the Sun. It has been present in many traditional building methods for centuries, but has become of increasing interest in developed countries as the environmental costs and limited supply of other power sources such as fossil fuels are realized. It is already in widespread use where other power supplies are absent, such as in remote locations and in space.

Answer 5

Whatever these people said, but I just want to add my two cents (or points). From what I heard on a similar topic on Answers, it only costs $150 to have a six-foot tall solar panel and connect it to your house. With a little creativity like hooking it up to a battery while you're gone for back-up or night power, it could save you a load on electricity bills.

Answer 9

okay walk outside during the daylight look up at the sun feel the heat then walk inside and slap you parents for doing drugs while they were conceiving you

Answer 10

Transferrance of the sun's light and heat into usable fuel.
