There is a lot of talk about the depletion of fossil fuels, such as oil, and that the world will run out of these fuels in the near future. One of the main advantages of solar energy is that it's not going to disappear anywhere.
Solar energy is the most 'green' energy source in the world. It does not damage the environment around it in any way. There are no residues, waste or byproducts of any kind and the process of capturing the energy does not produce any noise pollution.
No one wll charge you any money for harvesting the sun's energy. Once you have setup the solar panels, you can start converting solar energy into electricity for free. Thus you have no worries of spending a large portion of your salary on electricity bills.
Solar technology is very portable. You can unplug the panel and take it with you on a trip. Tiny solar panels are also available, which you can use to charge your electronic gadgets while you're on the move.
Solar energy along with other reneawble energy solutions such as wind power gives us the hope that in the coming days the environment around us will be much less polluted.
The cost factor has been something that has mitigated against solar panels. But, with the rapid growth in technology and increase in demand, solar technology is becoming more affordable. New developments have put solar energy on a par with coal manufacturing plants on a per-kilowatt basis. Hot water panel technology has also seen great improvement in recent years as well, and the payback times for domestic systems can now be as short as five years.
