One of the alternative renewable energy sources that are being used today is a solar energy. Solar energy comes from the sun and is converted into solar power through the solar panels. This kind of electrical power is said to be a more sustainable source of energy compare to fossil fuels. Solar panels proved to be more useful as an alternative power source especially when electrical power supply is accidentally cut off due to disasters or when the electrical power supplies have thinned down already. A solar panel is a set of photovoltaic modules that are electrically connected and mounted on a supporting structure. These photovoltaic modules are enclosed, connected assembly of solar cells. This kind of electrical power is said to be a more sustainable source of energy compare to fossil fuels. Solar panels proved to be more useful as an alternative power source especially when electrical power supply is accidentally cut off due to disasters or when the electrical power supplies have thinned down already. The solar panel can be used as a section of a bigger photovoltaic system to generate and supply electricity in commercial and residential applications. However, some residences use solar panels only to supply their homes their electricity needs. Even if solar panels and the use of solar energy gain popularity throughout the years, many homeowners are still intimidated to switch to it. And to shed light into this matter, below is a deeper discussion on the advantages of solar energy as well as the use of solar panels: 1. The use of solar panels takes advantage of the renewable solar energy from the sun and it avoids the emission of green house gases. Through this, solar power helps to lessen if not stop global warming. 2. Solar power can help you save money! Once a solar panel has been installed and maintained, solar power can be produced free of charge. But how much does a solar panel cost and how long before the return on investment? Generally a 240 watt mono-crystalline solar panel could cost around $12,300 and the return on investment in 5 years. However, the return on investment varies because a lot of factors have to be considered in calculating for this. 3. Solar power provides energy reliability. Solar power is seen to last forever compare to oil reserves that could last 30-40 years. 4. Solar power provides energy security. No one, not even companies can buy and monopolize solar energy. It avoids politics and price volatility that looms over the fossil fuel market. 5. Solar panels do not make any noise. Giant drilling machines on the other hand make a lot of noise. 6. The use of solar power can save eco-systems and livelihoods. The production and installation of solar panels do not cause destruction of forests. The panels can be set up in an open space or on the roof of buildings and houses. 7. There is only little maintenance needed, for solar panels to keep running. Aside from the stated benefits of solar energy and power, it should not be missed that solar power stimulates talks and reflections of the importance and inter-relation between economics, environment and investment.
