Solar energy is the energy obtained by capturing the light and heat emitted by the Sun.
He found that Discover: some materials Physicist generated Edmond electric currents Becquerel with the light exposition. It Studied theoriginates effect on the by Heinrich Hertz… solid, making solar cells that changes light into electricity. Used Czochraski Bell Labs… technique.
Photovoltaic solar panels: Thermal solar panels: are a set of photoelectric these solar cells together which forms panels absorb solar heat a solar panel. to heat water for domestic This solar panel produces use and home heating. energy through It consist of tubes mounted the photoelectric effect on aluminium covered that makes by a glass plate. Solar heat is them absorb photons of trapped between the light and glass and tubes. http://www.youtube.com/watch?v=gvFqwxgwsQc&feat release electrons. When ure=related these free electrons are captured, the result is an electrical current that can be used as electricity.
As the sun moves, some solar panels move according to the position of the sun.http://www.youtube.com/watch?v=nKa7- pFz2iY
Produces heat; for heating and water heater.Use 1: Sunlight transforms directly into electricity.Use 2:
Battery chargers, fans, garden lamps, water pumps... Today, almost everything can run with solar power. There are also many solar panels that appear every day in new roofs, and it can also heat our homes and power the most remote places.
Advantages Disadvantages-It is clean energy. -Requires large initial investment.-It is respectful to the environment -Require large land.-It comes from an inexhaustible -Is danger by the hightenergy source. temperatures reach.-Solar energy don’t produce -The places where there is morewaste. radiation, are desert places and away.-Do not use fuel. -It has less performance than other systems.
Is a method for obtainenergy which workswith the air heated bythe sun and risesthrough a chimneywhere the generatorsare.
