Solar Power Energy- It's Free & Pollution Free!
Energy is the capacity or ability to do any work. Energy is abstract as we cannot really see it. Energy has been around us since the beginning of time. According to the big bang theory the universe began when the infinite amount of energy suddenly began to expand. Study proves that there are several types of energy present in the nature, like mechanical energy, chemical energy, thermal energy, electrical energy, nuclear energy, solar energy etc.
What is solar energy?
Sun, is a star and its more than 1 million times in size when compared to earth. Solar energy is the form of energy which is obtained from the sun. This energy can be used by mankind in many ways- from heating water in our home to generating electricity. Plants also uses the solar energy through a process called photosynthesis to grow and indirectly we eat these plants in the form of fruits and vegetables and we in turn get the portion of solar energy in our body. Solar energy is produced from the light of the sun, not from its heat. That is why solar energy can be generated by cold countries also when the sun is bright and shining.
Solar Panels:
Converting the sun's energy into electricity by using solar cells is known as photo voltaic effect. Each solar panel consists of a group of solar cells. These cells are commonly made of silicon which is a semiconductor. Solar panels have two types of semiconductors, one is positively charged and other one is negatively charged. When sun light falls on these semiconductors the electric field between the two layers produces electric current. The amount of electricity produced completely depends on the intensity of the light from the sun.
Why use solar panels for producing electricity:
- Pollution free: The important benefit of using solar energy is that it doesn’t exude any kind of toxic air. It is 100% environmental friendly.
- Solar panel doesn’t make any sound while operating hence it does not make any noise pollution.
- Benefiting the economy of our country: Every year we use a lot of oil to run big machinery that can produce electricity required for our country. Solar panel does not require water or fuel to produce electricity. So we can free our country from transporting oil from different countries to produce electricity.
- Durability: Solar panel runs for more than 25 years without much trouble. They even work on cloudy weather conditions, provided there is sun's light.
Many companies have started manufacturing high quality solar panels that can be used in your home and office to produce electricity. Free Installation, repair and warranties are given by the companies itself, so it is hassle free. You can buy it from the company’s website or from any online portals.
