Solar energy is a fundamental source that is obtained in our surroundings. It is a renewable source that cannot be easily vanished. Using several technological devices, we can convert solar energy to electrical energy through various methods that are less expensive and very efficient.

Let us first understand the conversion of solar energy to electrical energy easily through a diagram.

Solar energy to electrical energy diagram

The process of converting of solar energy to electrical energy/current can easily analyze this process through a simple diagram that is shown below;

Firstly, the sunlight will strike the solar cells inserted in the solar panels. These solar panels will have the built-in technology to convert them into electricity. This electricity is generated through the flow of free electrons from the semiconductor. Later these are passed through a charge controller and later to the battery, then to the inverter; this inverter produces AC used in home appliances.

If we come to industrial purposes, then the ponds are constructed then these solar ponds are used to produce textile materials, swimming pools, food products, chemicals, etc.

What type of energy does solar energy belong to?

Solar energy is one of the most renewable energy sources found so far.

Renewable energy is nothing but a source of energy that can reconstruct, and solar energy is consideredto be the cleanest and purest forms of renewable energy. It is also abundant in nature and can be indirectly used in converting to various other forms of energy.

Can we assume solar energy to be a viable source of electricity?

Sun is the major natural resource of energy, and the energy produced by the sun will be enough to satisfy the energy need of the entire population.

As it comes under the category of renewable resources, it cannot completely vanish soon as compared to other energy sources. We can assume solar energy to be a viable source of electricity only if we can overcome the limitation of converting solar energy into usable electricity using inefficient and less expensive methods.

Why is solar energy considered an important source of energy?

Solar energy is one of the kinds of reliable energy sources and can be used directly and indirectly in generating power sources.

Solar energy is a major renewable forms of energy since sunlight cannot be completely extinct, as in the case of fossil fuels. It is less expensive and reliable as it doesn’t cost much to receive and use sunlight. It is the main reason for considering solar energy as an important energy source.

Mention the major characteristics of solar energy?

The major characteristics of solar energy that make it an important source of energy are as follows,

  • Solar energy is renewable.
  • It is inexhaustible.
  • It is a clean and abundant form of energy.
  • It can be converted into other forms directly or indirectly using natural and technological devices.
  • It is reliable.
  • It is cost-effective.

How can we convert solar energy to Alternating current (AC)?

Every household uses an alternating current that reaches the home after many processes.

Nowadays, all solar systems are built with an important inverter device. The main work of inverters is to transform the collected amount of energy from the sunlight with the help of solar panels or solar cells to the required amount of energy and later to power or electricity. This inverter acts as a major key that helps in converting the obtained direct current into alternating current. It is the way how solar energy is converted into AC.
