Solar energy is defined as the transformation of energy that is present in the sun and is one of the renewable energies. Once the sunlight passes through the earth’s atmosphere, most of it is in the form of visible light and infrared radiation. Plants use it to convert into sugar and starches and this process of conversion is known as photosynthesis. Solar cell panels are used to convert this energy into electricity.
Advantages of solar energy are:
1. Clean: It is considered to the cleanest form of energy as there is no emission of carbon dioxide like in case of fossil fuels which is one of the causes of global warming.
2. Renewable: There is an ample amount of energy available on earth as long as the sun exists.
3. Reliable: The energy can be stored in the batteries and so there is no question of unreliability.
4. Free energy because it can be trapped easily.
Disadvantages of solar energy:
1. The production is low during winters and on cloudy days.
2. Installation and the initial cost of the materials are expensive.
3. Space consumption is more.
