solar powered satellites and devices get electrical energy from?
Answers
Explanation:
this is the answer for your question
the answer is .....
Energy from the Sun (solar power)
Solar power is energy from the Sun. Spacecraft that orbit Earth, called satellites, are close enough to the Sun that they can often use solar power. These spacecraft have solar panels which convert the Sun's energy into electricity that powers the spacecraft.......
How is a satellite powered?
The Sun is the main energy source for satellites, which is why all satellites have solar panel arrays mounted on them. Each array contains thousands of small solar cells which are made of silicon – a material that allows sunlight to be turned into electrical current..........
What is the source of electricity in the satellites?
The Sun is a very powerful, clean and convenient source of power, particularly for satellites. The only thing needed is a means to convert the energy contained in the Sun's radiation – mainly light and ultraviolet rays – into electrical power........
Can solar cells produce electrical energy?
You now have solar panels working efficiently to transform sunlight into electricity, but the electricity generated is called direct current (or DC) electricity, which is not the type of electricity that powers most homes, which is alternating current (or AC) electricity.....
How do we get energy from space?
Optical reflectors concentrate the sunlight, photovoltaic cells convert the sunlight to electricity, and an integrated circuit converts the electricity to radiofrequency energy that is transmitted through an attached antenna. Many individual tiles could be strung together to form large solar arrays in space.......
Do satellites run out of fuel?
Satellites do carry their own fuel supply, but unlike how a car uses gas, it is not needed to maintain speed for orbit. It is reserved for changing orbit or avoiding collision with debris....
