One of the most important companies in solar energy, Suntech Power Holdings Co. Ltd. It has announced the project to build a solar in Tibet Park approximately 4000 meters above sea level, which makes it one of the highest in the world.
The site that will be installed this solar Park is located on the Tibetan plateau, near the village of chek kang in the province of Shannan. The natural characteristics of the place, with an intense sunlight and low temperatures make it extremely viable for the use of photovoltaic panels with advanced technology. The project is aimed at the generation of 20, 000MWh of electricity per year.
According to the founder of Suntech, solar energy in Tibet will allow not only increase the volume of energy production in the country (until today heavily based on hydroelectric power), but it will also serve to replace or complement to hydraulic in drought situations plants as those that have recently affected the region.

Photovoltaic Conversion Process.
We have already given unto a first part of this report talking about the photovoltaic solar energy. Now is the turn to see in detail what is the process of photovoltaic conversion that we had briefly mentioned in our previous article. Photovoltaic conversion (FV) or photovoltaic conversion process is the process where the sunlight is converted into electricity using photovoltaic cells.
This process was discovered and proved by the French scientist Edmond Becquerel in 1839. While experiencing noted that certain materials when they were exposed to sunlight generated a difference of potential; and connecting to an external load produced current electric. They called this physical phenomenon "photovoltaic effect".Other scientists as Heinrich Hertz also investigated this topic important progress, but it should spend a long time until this discovery could be implemented in the production of solar energy generating devices.
Let's see what is happening to that solar energy is transformed into electricity using photovoltaic conversion (photoelectric effect). To illuminate a material determined with electromagnetic radiation (usually light ultraviolet or visible), the emission of electrons occurs.This is what happens when solar radiation enters the photocell: emit electrons of the atoms and begin to circulate through the material.Measure the voltage at the two ends of the material, sees a difference of approximately 0.5 to 0.6 Volt has generated.
