Solar energy is free, renewable, and on top of all, clean. On the other hand, fossil fuels such as gasoline and coal are non-renewable, which means they do not replenish themselves. This is why they are getting more and more expensive every day. As long as the sun is still shining, we will never run out of solar energy. Having your own solar power generator at home is like having a lifetime supply of electricity. It will never wear off or expire, as long as it is still in good condition.
A solar panel is a device used to gather the sun's rays which are later converted into electricity. A solar panel is only a small part of a solar power system. It is usually placed at the rooftop or higher places, so it can get enough sunlight to generate enough electricity to power a home. Solar power is a great alternative to fossil-based energy resources. As we all know, the emissions from fossil fuel are the main cause of air pollution, which contributes to global warming.
