Solar Energy : Any type of energy generated by the sun.
Solar energy is a very popular form of energy nowadays. There are so many houses, shops, offices, schools, and colleges who use solar energy to fulfill their need for electricity. Solar energy is the energy which we get from the sun and converted into thermal or electrical energy with the help of photovoltaic cell. Solar energy is a renewable energy because it will never end as long as the sun remains. Solar energy also a pollution-free energy because there are no harmful gases, chemicals, fly ash produced during the production of solar energy.
When sunlight comes to earth and falls on a photovoltaic cell it generates electricity by an electronic process and the electric energy stores in the batteries in chemical process and can be used to supply power anything from a small electronic gadget such as calculators and road signs up to homes and large commercial businesses. As pollution is a very big problem in recent times so the Solar energy is producing a large number in many large countries to keep the environment clean and air pollution-free. Also, some countries announced that their citizens have to install the solar panels on the rooftop of their house or have to plant trees. Solar energy is not only pollution-free energy but also its maintenance cost is very low so to maintain a solar power plant less manpower is required than a thermal power plant. Also, one can set up solar panels on the rooftop of the house or office. To get rid of the pollution, which is a global problem in recent days and we need to shift from non-renewable energy to renewable energy like solar energy. If one sets up a solar panel in the rooftop of the house, office the annual charges of the electricity will reduce.
With all of these advantages, there are also some disadvantages when we use solar energy. The first disadvantage of using solar energy is that its initial setup cost is very high. To store the solar energy in a large number one needs a personal room for the batteries. If the solar panel damages one has to replace it with a new one if the warranty period of the panel expires, and the price of a new solar panel is high. When the batteries are damaged one has to replace the batteries and it will pollute the environment chemically because the batteries store the electrical energy in the chemical form. The changing cost of a battery is very high. If a person sets up solar panels in house or office, he must have to hire a solar panel specialist if there any problem occurs in the solar system. Even though there are some problems solar panels will save our money as well as the environment.
