People begin to pay close attention to environment protection because of the bad effect that the development of industry brings. More and more problems appears due to the continuous pollution to environment. We should stop destroying our earth by getting along with environment amiably and peacefully or we must pay the price one day! Solar energy is a green energy which will also last for a long time. Solar panel is created to be a new way to develop this green energy. Solar panel system works in a complex way. Put simple, it turns the solar energy to electricity. The photovoltaic panel or the solar panel absorbs the solar energy and then an electric current is produced when the solar energy comes into the panel and begins to flow. Actually, the panel is made up of many solar cells which are mainly made of silicon-a semi conductor that can turns solar energy to electricity.
Solar panel is used in military at the very beginning but with the more and more serious environmental problems appearing, people start to think about using it in other fields even household. Although it is still very expensive to install a solar panel personally, it is true that the solar panel will be an important tool in the future. Because it has so many wonderful benefits which are as followings:
At first, it is absolutely free and green. The lifespan of the sun is about 60 hundred million, which means the solar energy can almost be regarded as a kind of durable energy and the solar energy is huge which needs any pay. At the same time, it is green to use for that the consumption of solar energy will result in no pollution. It is an eco-friendly, clean and cheap. Then, it is quiet and easy to be use. It has no moving parts so we will never be worried about too much noise which we now may be suffering from. And it is also easy to be used which offers low maintenance and you just need to keep the surface of panel clean. Besides, it is cost effective. It can work for even 25 years or more, so it is rather worth using. You can use the solar power to heat and power your home free for such a long time after installing, are you moved by that?
For the moment many new kinds of solar panels are developed, and it is believed that solar panel will step into our life after constant working and research on cutting the cost and promoting the performance of it.
