What energy transformation in solar panel?
In a silicon solar cell, light energy (a photon of energy >~ 1.1eV) is absorbed in silicon and the energy absorbed excites an electron-hole pair so charge particles are formed. If there is an electric field, the charge particles will separate and an electric current occurs.

How important is solar energy in the future?
Need answer now.....so that i can finish essay
How is the sun's energy solar energy?
the suns energy is solar energy because sun means solar so solar energy is from the sun
Is solar energy more efficient than electrical energy?
The two can't be compared. If you use solar energy, you'll also be using electricity - the electricity from the solar panels (unless you are talking about the other type of solar panel: the one used to directly heat water).
How can solar energy be useful directly by animals?
it's useful for snakes because they need alot of heat so insted of using electric we could use solar power.
An energy source that will never run out?
There are no energy sources that will never run out, but the sun will last a good long time, so any energy derived from solar will last a good long time. This includes direct solar, such as roof mounted water tanks, conversion of solar to electric by solar cells, bio-solar (grow things which convert to energy), wind, water, earth thermal, and similar.
How do you make schools energy efficient?
you have to : use energy efficient light bulbs solar panels motion sensitive taps ( so water dont drip) unplug electric things
Why is renewable energy not so commercialized?
Renewable energy is not so commercialized because it is too expensive. If you were to place enough solar panels on your roof to be able to just use solar energy, you need ten years worth of time in order to make the electric bills the same, and that does not include the expensive batteries that need replacing!
Why is solar energy so expensive?
Solar energy is so expensive because it is a relatively new concept for energy. The technology involved with bringing that energy to consumers is expensive.
Why is solar energy so popular?
among the other sources of clean energy, solar energy is abundant and easier to collect.
