Why Solar is important in our life?

Solar energy is an important part of life and has been since the beginning of time. Increasingly, man is learning how to harness this important resource and use it to replace traditional energy sources.

Solar Energy Is Important in NatureSolar energy is an important part of almost every life process, if not, all life processes. Plants and animals, alike, use solar energy to produce important nutrients in their cells. Plants use the energy to produce the green chlorophyll that they need to survive, while humans use the sun rays to produce vitamin D in their bodies. However, when man learned to actually convert solar energy into usable energy, it became even more important.

Solar Energy Is Important as Clean Energy

Since solar energy is completely natural, it is considered a clean energy source. It does not disrupt the environment or create a threat to Eco-systems the way oil and some other energy sources might. It does not cause greenhouse gases, air or water pollution. The small amount of impact it does have on the environment is usually from the chemicals and solvents that are used during the manufacture of the photovoltaic cells that are needed to convert the sun’s energy into electricity. This is a small problem compared to the huge impact that one oil spill can have on the environment.

Solar Energy Is Versatile

Solar energy cells can be used to produce the power for a calculator or a watch. They can also be used to produce enough power to run an entire city. With that kind of versatility, it is a great energy source. Some of the ways solar energy is being used today are:

  • Cars
  • Cooking
  • Coffee Roasters
  • Electricity for homes and businesses
  • Thermal heating for homes and businesses
  • Watches
  • Water heaters
  • Water treatment plants

There are many other things that are or can be powered by solar energy.

How Do Solar Panels Work?

The complicated science of how solar panels convert sunlight into electricity is beyond the scope of this article, but it is possible to understand the general idea of solar power production without getting too technical.

Photons Into Electrons

The solar panels you see on a landscaping light or a calculator are made of photovoltaic cells. The purpose of these cells is to convert the light from the sun into electricity. Photovoltaic cells are typically comprised of silicon that acts like a semiconductor. When sunlight hits the silicon, the energy from the light is absorbed. Silicon is an excellent choice because of its atomic-level properties. In its natural state, silicon has the space for eight electrons in its outer band, but only carries four. Therefore, when two silicon atoms meet, each atom shares its four electrons with the other and a stable, strong connection is created. There is no positive or negative charge here, however, since each atom is receiving exactly what it needs.

For silicon to work as a material to produce energy, it must be combined with another element that has either a positive or negative charge. An element like phosphorus has five electrons, so when it is combined with silicon, the bond will have eight shared electrons with one free electron that is not needed by the silicon yet is still bonded to the phosphorus. This creates a negatively charged combination.

However, for an energy current to flow, there needs to be a positive charge. To accomplish this, silicon atoms are also combined with an element like boron that only has three electrons. Now the boron is completely bonded, but there is still a space in the silicon atom for another electron. In solar panels, this positively charged plate is put together like a sandwich with the negatively charged plate, and conductive wires are placed between them.

This is where the photons from the sun come into play. When the negatively charged plate in the solar panel is faced toward the sunlight, the photons from the sunlight blast away at the solar panels until they eventually knock the extra electron on the negative plate loose. The positive plate that has a space for the extra electron quickly gathers the freed electron up. As the photons from the sun keep breaking off electrons, an electric current is created. At this point, metal contacts are attached to each side of the photovoltaic cell so the current can be drawn off and used as electricity. Depending on the size of the photovoltaic cell and the electric fields built-in to the cell, the wattage of the cell will vary.​

Limitations of Solar Power

Now that you have a basic idea of how solar panels work, you might wonder why solar panels aren’t the primary source of power in the world. The problem is that it is still not a very efficient process for generating power. The amount of electricity created by solar panels is relatively low compared to the size of the panels. Plus, the angle of the solar panels is very important; if the panels are not facing the sun just right, the efficiency can drop considerably. Solar panels are getting better and better, but engineers are still searching for ways to make them more efficient, smaller and easier to maintain.
