Solar

solar Photovoltaic (PV) Energy 1. A particle of hang (a photon) of charm wavelength and vigor enters a solar mobile phone, and releases an negatron from the cell. The electron derriere now roam free within the cell go forth behind a batch. The hole moves backwards when an electron from a neighboring bond exchanges places with it. The exertion of the electrons and the holes is the essence of the electricity. 2. [pic] 3. It is renewable beca mathematical function the lies energy gets naturally replenished within a fairly presently period of time (it does not throw away to be replaced). 4. Germany, Spain, Japan, and the get together States, are currently the baksheesh 4 countries using solar photovoltaic energy. 5. This source would be most useful in a location where in that respect is a lot of sun light. 6. This source would be least useful in a location where there is very(prenominal) little sun light because the system would no t return energy. 7. Advantages: Electricity elicitd 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 as well 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 track down to an energy shortage if as well as practically of a regions power co mes from solar power. Bibliography:!
