1. A particle of precipitate (a photon) of charm wavelength and vigor enters a solar cell, and releases an negatron from the cell. The electron derriere now roam free within the cell go forth behind a hole. The hole moves backwards when an electron from a neighboring bond exchanges places with it. The movement of the electrons and the holes is the essence of the electricity.

3. It is renewable because the lies energy gets naturally replenished within a fairly presently period of time (it does not have to be replaced).
4. Germany, Spain, Japan, and the get together States, are currently the top 4 countries using solar photovoltaic energy.
5. This source would be most useful in a location where there is a lot of sun light.
6. This source would be least useful in a location where there is very little sun light because the system would not generate energy.
7. Advantages:
Electricity produced by solar cells is clean. Because they do not use fuel other than sunshine, PV systems do not pollute the environment.
Solar energy is a topically available. This reduces environmental impacts associated with transportation and also reduces our dependence on merchandise oil.
Disadvantages:
Some toxic chemicals, like cadmium and arsenic, are apply in the PV production process.
Solar power is an inconsistent energy source. Solar facilities may produce no power at all some of the time, which could lead to an energy shortage if as well as much of a regions power comes from solar power.
