Solar panel systems also referred to as Solar photovoltaics (PV), are devices that help us capture the energy from the sun using photovoltaic cells. These cells are responsible for converting the solar energy into electricity and they do not require sunlight in order to function. The photovoltaic cells are capable of producing electricity even in cloudy days and the electricity generated here is used to operate household appliances and the lighting systems in our houses. Today, most households are turning to solar energy and this is as a result of the many benefits it offers. In this article, we are going to take a look at solar panels in particular.
Solar panels are generally used in most households today to provide electricity and as mentioned above is due to the many benefits they give us compared to the convectional sources of electricity. Solar energy is entirely free, and so, once you have paid for the initial installment cost, your utility bill will significantly reduce in the long haul. You will also find that most governments across the globe pay homeowners for using solar electricity so that the use of solar energy can be encouraged. This is yet another advantage of using solar electricity to power your home. You may contact your local solar power company to know more about these government rebates and all other solar energy information you may want to know.
If you are able to produce excess electricity than you require through solar energy, you can also be able to sell it to the grid, and this becomes a great way for you to earn some extra money. Ideally, solar electricity is eco-friendly, meaning it does not harm the environment by producing harmful elements such as CO2 and other harmful substances. An average home using solar energy is able to save over a tone of CO2 per year and this is quite a large volume in an individuals lifetime. If more and more people swith to this form of energy, then imagine the tonnes of volume in CO2 we would save.
Well, solar panels are made using layers of semi-conducting elements such as silicon and once sunlight hits these panels, it creates an electric field across these layers. Therefore, the stronger the sunshine, the more electricity the panels will produce. This is why most panels are placed on the top of the roof for maximum exposure. Today, you will come across solar tiles rather than panels. These are made to be used as a roof, and even though they might be twice as costly, they are much more cost effective.
