Solar cells create their energy from photons. Photons are what make up light. At night there is no light so therefore there is no energy created.
Photovoltaics (PV) are the direct conversion of sunlight into electrical power.
A solar PV system uses the natural energy from daylight in the form of solar radiation to generate electricity.
Becuase the earth is always spinning on a tilt so that it spins around and the Sun is shining on the Western Hemisphere and then it will keep on spiining until the sun is shining on the eastern hemiphere of the earth. It keeps on spinning and spinning creating night and day. That is why Asia and places near there are a whole day apart from us.
Because at night, it's at the other side of the Earth.
A night its dark.
Cause its night STUPID
The Sun is a star, that only comes out at day, all the other stars you see at night are still there but you cant see them.:)
The sun shines to the moon at night time
At night, or during an eclipse of the Sun, or when it's cloudy.
well you can if you look carefully but you cant see it because the sun gives the moon its light at night and if the sun is not on that side then you wont be able to see the other side like you can the other
Cause its night STUPID
because of the sun
Night time
At night.
The Sun is a star, that only comes out at day, all the other stars you see at night are still there but you cant see them.:)
The sun shines to the moon at night time
The stars that you would see at night in 6 months time.
It is dark at night because the Earth goes aruond the sun and it cant be day all the time.
it doesn't go know were you just cant see it because its dark
At night, or during an eclipse of the Sun, or when it's cloudy.
Because Earth is turning. It's only ever night time on one side of the Earth, the side not facing the sun.
There is a very simple reason why the sun is not seen at night. The following argument is presented in all seriousness: What are the definitions of "day" and "night" ? They are, respectively, the period of time when the sun is up, and the period of time when the sun is not up. The sun is not seen in the night, simply because we define "night" to be the time when the sun is not seen. We don't define day and night in terms of the moon, since its influence on our ability to get around and pursue our activities is relatively negligible.
