If you do not have easy access to affordable gas energy in your house, you might be forced to make use of more electricity. The option of using more electricity is quite expensive in spite of the fact that you use the most efficient and very best water heating mechanisms and electric radiators. The best thing that you can do in this situation is to consider the installation of solar panels in your house. This can help you in saving money on electricity bills and even in making money through the excess energy that is produced by the solar panels. But it is important for you to know how does solar power work in order to decide whether installing solar panels is the best thing that you can do for your house. In this case, information would serve as great power for you.
Photovoltaic Solar Plates
The other name for solar panels is photovoltaic panels where photo means light and voltaic means electricity. This is electricity from light or to be more specific electricity from sunshine. In 1839, a scientist discovered that it was quite possible to convert the sun’s energy into electricity. Nevertheless, this idea was not able to catch on until the year 1960 when solar panels were introduced for the first time on spacecraft.
How Solar Energy Works?
Solar panels are made up of several small solar cells. These solar cells have the ability of providing small amount of electricity. Each solar cell is made up of silicon crystals in two layers with each layer being treated in order to gain or lose electrons. The top silicon layer needs to transfer electron to the bottom silicon layer. This procedure can take place by exposing the solar cells to light. Sunlight excites electrons found on the top silicon layer resulting in the flow of electrons to the bottom layer. However, in order for the electrons to pass from the top layer to the bottom layer due to the effect of sunlight, they must be passed by way of metal contacts between the top and bottom layers. Thus, a circuit is formed and electricity is produced. If you are looking forward to getting extra electricity, you will have to add extra solar cells to your solar panels. The more solar cells you have the more electricity can be produced. Most homes generally require around 4 to 8 kW for basic functioning. You can also make good profits by selling excess energy to the energy providers. However, this will completely dependent on whether there is any such scheme running in your locality.
Getting Electricity to Your House
Solar cells produce useful electricity but this type of electricity is not useful for your house. The electricity generated by solar cells need to be transformed from DC or Direct Current to AC or Alternating Current. The entire procedure is accomplished by making the effective use of an inverter stored within the house. The use of the inverter for converting electricity generated by solar cells makes it safe to be used in homes in the form of normal electricity.
What if the Day is Sunny?
Solar panels work in sunlight and not necessarily when the day is sunny. In sunny weather, more electricity can be generated using solar panels. However, the solar panels will still work even during cloudy weather. It is to be understood that solar panels require light and not heat for generating electricity. Perhaps, one of the best types of weather for producing solar energy is very bright and cold such as crisp winter mornings.
Renewable sources of energy are always best to be used because they can be used very easily and also because they are highly reliable.
