Renewable energy instalation

Abstract

Renewable energies nowadays are a great option to supply industries and houses. Or even to supply electric energy to the national grid. The technologies about how to develop these clean energies are improving year by year. There is need more power to supply the needs of the people, but the use of fossil fuels should be decrease because the environment it is getting hurt by the air pollutants. So there is a good solution to generate electric energy from clean sources. Some companies work for that second option. They use huge fields full of solar panels to supply the network that will supply to the rest of people who are using electric energy. The range of power uses oscillates between from 100 to 320 watts. There are some specifications that depends on every singular solar panel. Every of them have their own characteristics in terms of power, efficiency and so on. Actually nowadays the best sunlight conversion rate is around 21.5% in new commercial products.1 A good option also is the use of aero generator to exploit the wind. Exists some ranges to describe the turbine power, from Class 1 (200 watts per square meter or less at 50 m altitude) to Class 7 (800 to 2000 watts per square m).2
