Solar is a Latin word for 'sun' and the sum is a powerful source of energy. We can use solar power in two different ways as a heat source, and as an energy source. We can use solar collectors for heating water and air in our home.
If you have seen a house with big shiny panel on the roof, that family using solar power. We can also use solar energy to make electricity. The process is called photovoltaics, and it uses cells known as solar cells.
It is a fact that the sunlight that shines on Earth in just one hour can meet the energy demands of the world for one year!
Soar energy is clean, safe, and renewable but it is still expensive, and solar cells need a lot of space. In the future hopefully, solar energy will become more economical and easier to harness, and convert into electricity.
