How Does Solar Panels Work?

»Posted by on Dec 21, 2018 in solar packages in Perth | 0 comments

A solar panel is a collection of several solar cells that can transform light into power or electricity. By consolidating the capacity of several solar panels, they can possibly cover the daily electricity requirement of a small family.  

Depending upon the type of solar panel used, 5% to 22% of light energy can be transformed into electrical power. This is known as the yield or output of the panel. As innovation constantly enhances everyday living, that output is expected to increase further. 

With the use of solar panels, it is possible to transform daylight, which is free and boundless, into electrical power. This transformation is accomplished because of the presence of semiconductor materials that make up each solar cell.  

The Generations of Solar Panels  

The material commonly utilized for solar cells is silicon and silicon comes in three forms such as mono-crystalline, polycrystalline or multi-crystalline and shapeless silicon. These different forms create distinctive types of solar panels with contrasting costs, longevity, and yield.  

The first-generation solar panels utilize mono-crystalline or polycrystalline silicon with a yield of 12% to 19%. The second-age solar panels comprise of solar cells made of nebulous silicon. This name applies to solar panels that are made available up of late, such as the CIS copper-indium-selenium, CIS copper-indium-gallium-selenium, and CdTe cadmium telluride. 

The distinctive element of the second generation solar panels is its thin semiconductor layers. Such is the reason why these panels are more affordable and more stylish, yet they have a considerably lower yield of just 5% to 11%.  

The Components of Solar Panel 

The converter is a vital component of a solar panel installation. Solar panels create direct power current. To utilize such current in your home or to place the surplus on the grid, it must be converted into an alternating current of 230 Volts. This is performed by the converter, which is connected to the electrical circuit near the solar panels.  

The capacity of a solar panel installation is expressed in watt peak or Wp. This is the maximum power capacity that the solar cell can yield under perfect conditions, which means that the solar panels are directed towards the sun and there are no clouds in the sky.  

The perfect orientation for solar panels is facing south. In the event that the panels are installed between the southeast and the southwest, the loss of yield adds up to 5%. On the off chance that the panels are installed outside these limits, then the loss increments quickly.  

The Power Generation Levels to Expect   

When installed in the most ideal manner, solar panels with an area of 10 square meters are expected to produce 1,000 kWh per year. If a home uses around 3,500 kWh per year, then it’s safe to say that the solar panels covering 10 square meters can generate around 33% of the family’s yearly electrical requirements.  

It is usually hard to utilize more space for solar panels in the city. But as the yield of the solar panels is increasing considerably over time, it will be conceivable to cover a higher extent of the everyday power requirements with a smaller surface area. If you want to install solar panels in your home, learn more about the solar packages in Perth so you can choose the one that suits your requirements.
