The Energy

The power plants, exactly receive prominence for its great importance in the process from creation of the sustainable development of any nation, and for its importance as source competitive advantage for the productive units in the market. You vary clean power plants are being developed and used to cure this Brazilian deficiency. But one of these power plants calls the attention for its efficiency as alternative source of energy, in the containment of costs with electric energy and others in the process of generation of auto-sustainable energy, promoting redirecionamento of energy comings of hydroelectric plants and diminishing costs of energy for the companies, is the solar or fotovoltaica energy. The fotovoltaica solar energy, fruit of the direct conversion in electricity, the form that has presented the development more notable in recent years. The fotovoltaicos systems have received great attention from the community international technique. As consequence, they have been pointed as ones of the great chances in the energy sector in this principle of millenium.

Systems of fotovoltaica generation have been used of two forms: separately and in co-generation. In companies who are in remote localities, that not they count on supply of conventional electric energy, in regions of difficult access to the electric net, and in great urban centers that search alternative power plants for the high indices of consumption, isolated fotovoltaicos systems can be the solution. In this in case that, the generated energy must partially be stored in banks of batteries. The excess of energy generated during periods of raised solar radiation, or low consumption, can be stored, for use during the night, for example. Fotovoltaicos systems can be the principal source of energy for enterprise consumption. To another possible situation it involves the use of a fotovoltaico system of generation as a source of electricity hardwired in parallel with the electric net, in co-generation. In this system, the consumer primarily uses the energy generated local in fotovoltaicos panels.
