Advantages of Solar Energy

Solar energy has many advantages not only is it cost effective and emission free, but it is derived from a renewable source of energy as well, that is the sun. Its equipment is easily installed and easy to maintain. The power generated from solar energy is the same as others sources of power, but it can also be stored and further channeled into other form of energy such as heat energy. Solar energy can be used to heat up water in swimming pools, helps in cooking food and can also provide indoor lighting.  It does not deplete the earth of it fossil fuels and does not contribute to the carbon foot print left by man.

Why is it important to conduct research on solar energy?

Due to the changes occurring in our environment and the threat of global warming becoming a reality, solar energy research is becoming more and more important. Our planet is under the constant threat of changing weather conditions as well. In order to overcome this situation and reduce the effects of carbon emissions caused by the consumption of fossils fuels, new breakthroughs have been made in researching alternative energy sources. Many countries have started spending millions of dollars trying to discover methods to preserve energy and utilize alternative energy sources. One of the best solutions to reverse the effects of environmental damage is in utilizing solar energy to generate electricity.

What is the advantage of generating electricity with solar energy?

Solar energy helps generate “green” electricity, as it does not release carbon emissions in the environment. This is one of the most environmentally friendly methods of energy generation, as it does not contribute to man’s carbon foot print. All other methods that utilize fossil fuels are releasing carbon emissions in the air which are damaging the earth’s atmosphere and contributing greatly to the green house effect.

How can solar energy generate electricity?

The source of solar energy is the sun and its rays can be harnessed with the help of PV panels. PV or photovoltaic panels are very sensitive to the sun’s rays and with the help of solar cells (which are present within the PV panels) they can create current electricity. They actually do this with the help of photo voltaic material present in each solar cell. This material generates electricity when exposed to the sun’s rays due to the photodiode effect. Thus the energy generated with the help of PV panels can power up anything; even a small appliance like a calculator, to large buildings and even industries.

Where can photo voltaic panels be placed?

PV panels can be placed anywhere, and can be built small or large enough to power anything. They can be fitted on tall buildings and even in on street lamps. They can power a small appliance like a calculator or a watch battery, and make it work and they can be fitted on the roof tops of houses and industries to provide them with power. Solar powered street lights are now being used worldwide to light up parks all across the world and streets during the night. These PV panels can be used on a larger scale and can be put to use in the industrial sector as well. Industries are the biggest contributors to world pollution, and electricity generated through PV panels can be used in the processes of distillation, water purification, sterilization, disinfection and also space lighting. Space cooling and heating of water can also be done on an industrial scale with the help of solar panels.

Some uses of PV panels:

Swimming pools have PV panels fitted in them to have their water heated during winter.  Solar energy is also being used as a primary power source in some places, especially villages in developing countries. Due to the lack of infrastructure in the developing world, there is no electricity in the villages as the power houses are far off from these places and there is a lot of distance between one grid station to another. In such situations electricity cannot be supplied to these villages. Alternatively, energy can be supplied through PV panels to these rural villages. Solar energy can be utilized as the primary source of energy generation to supply streets, homes, schools and hospitals in such villages. Solar energy is also being utilized to power “green” vehicles as well. Since solar energy is extremely cost effective, its usage is greatly increasing with the growing needs of society.

Solar energy helps save on electricity bills:

Solar energy, if not used as the primary source of energy can be used as the secondary source of power generation for homes. People have started integrating PV panels in their homes, in order to generate electricity with the help of these panels. If there is a shortage in the primary source of energy, solar energy can be put to use in making electricity when back up is needed. In Australia many people have started utilizing PV panels to make electricity because it helps in saving a lot of money on electricity bills.
