We talk about the importance of renewable energy as it is of great use today is also friendly to the environment, there are a variety of these types of energies such as wind,geothermal, biomass and solar energy as is the energy collection through solar panels with photovoltaic cells.

Use of solar panels
The idea of ​​harnessing solar energy a startedover 100 years, but the technology was not as widely used as now. With companies finding new ways to use renewable energy sources, solar energy will become increasingly important.
Solar energy is oneof the most important energy source that is abundant. The sun will always be there, and we have to do massive excavations to find, apart from that we know that every morning will come from the east.However, to harness solar energy, we should use solar panels, because without them the use of solar energy is virtually impossible.

Solar panels work in two different ways. First we solaresque cellsconvert sunlight into electricity. This type of solar panels are rather expensive, pr they are not so popular when it comes to using solar energy. Still available in many products.
The other way isto use solar panels harnessing the sun's heat. The solar panel traps heat and warms a liquid to heat it to boiling point. With steam, move turbines and generate electricity. This process is simple,cheap and effective.

Solar panels come in different forms and there is no accurate way for everyone.
There are also different forms of solar energy. This for example solar energy concentration, whichis a sea of ​​mirrors facing one place. Usually these plants are in the desert. Produce energy in this way is more expensive than wind power but less than solar PV.
Speaking of using solar energy inthe home, known as solar heaters, a form of solar panel, is the most efficient, economical and effective we can find.
Solar panels are important for the evolution of society. They are important...
