Solar energy facts

What is solar energy?

Fossil fuels are fast being depleted by the vast energy requirements of the world, and the carbon emissions that are produced by them are very hazardous for our environment as well. Solar energy is a form or renewable energy that can be utilized by us in order to generate electricity instead of using the fossils fuels of the earth. Solar energy is the energy obtained from the sun, and can be harnessed with the help of PV panels to produce emission free electricity.

It is a fact that solar energy has been utilized by man since the ancient times. All the great ancient civilizations like the Mayans, the Egyptians, the Romans and the Greek used the power of the sun for many purposes including heating water and lighting indoor spaces. The ancient people understood the power of the sun; they understood that the sun has a power that can be utilized for many purposes. They also created sun clocks to tell the time of the day and used solar power to heat water in pools and for indoor usage. Today, the sun’s rays can once again be utilized to power our lives. Solar energy is the answer to the fast depleting Fossil fuels that are being utilized and are also releasing emissions that are polluting our atmosphere.

How can solar energy be utilized?

From all the alternative sources of energy, like geo thermal energy, wind turbines and wave power, solar energy is the easiest to utilize. It is the most easily attainable, and is highly cost effective as compared to other forms of alternative energy. In order to harness solar energy, PV panels, or photovoltaic panels need to be setup. These panels actually consist of solar cells or photovoltaic cells that are made of a photovoltaic material. This material is able to create electric current once it is exposed to solar energy from the sun. PV panels are being fit into many appliances like street lights, swimming pools and even cars so that an alternative source of energy is ready whenever you need it. Solar energy can also be stored and be used as a backup source whenever a primary source of energy fails.

Facts about solar energy:

Here are some facts about solar energy:

  • The unit of measurement of Solar Energy is kilo-watt-hour. 1 kilowatt = 1000 watts.
  • A solar system for the home is typically composed of solar panels, a battery, an inverter, a charge controller, support structure and wiring.
  • Around forty solar cells are combined into a solar panel and around ten to twelve panels are usually mounted to receive the maximum amount of sunlight.
  • If used as a backup, a solar energy power system can provide electricity twenty four seven, even on days that are cloudy and at night.
  • Solar energy can actually be collected and stored in batteries, it can be reflected, it can be insulated, and it can be absorbed and also transmitted.

Uses and advantages of solar energy:

  • Solar energy is definitely much more environmentally friendly as compared to traditional forms of energy with absolute zero emissions. It does not use up any of the natural resources of the earth or increase the carbon foot print.
  • With the help of solar energy, water can be heated and electricity can also be generated for many appliances.
  • Solar energy can actually be utilized to heat swimming pools, power cars, calculators and other small appliances. It can also power attic fans and it can be utilized to produce lighting for outdoor and also indoor places.
  • PV panels are being fitted on street lights, on roofs of houses and even cars to produce electricity.
  • Food can be cooked with the help of solar energy as well.
  • With the help of photo voltaic cells, solar energy can also be used to dry clothes
  • Industries utilize solar energy for the purposes of distillation, lighting, water purification, sterilization, disinfection, space heating, space cooling and many more purposes.
  • It is a renewable from of energy, since it is attained from the sun, it can be obtained every time the sun is shining. It can also be stored by the solar power cells so even on a cloudy day, or during the night time it can be utilized. It doesn’t deplete the earth of any of its resources as well.
  • It is free of cost since it is attained from the sun, and since it comes from a seemingly endless supply, the sun, it can be used up as much as possible without any harmful effects.
  • The equipment used to harvest solar energy is very easy to install, and usually comes with a five year warranty.
  •  Photo voltaic panels can be purchased on a small scale and a large scale as well; you can get small Photo voltaic panels for small appliances like a calculator, and even get Photo voltaic panels fitted on a huge scale like in homes or industries.
  • Photo Voltaic panels don’t require too much maintenance as well. Once they are fitted, they usually last a lifetime.
