Solar Panels Photovoltaic
Introduction to Solar Panels Photovoltaic
Solar energy is used to transform the sunís natural energy into a renewable source of energy that is usable to us. This process is completed by using the technology found in solar panels photovoltaic. Humans have been using the sunís energy since ancient times and today it is considered the fastest growing source of renewable energy in the world. Since the sunís rays are readily available and there will always be a continuous source of energy available, it is no wonder that we turn to this powerful energy source to help us.
The sun emits two types of energy that we are able to convert into usable energy and they are light and heat. The light energy is collected by solar panels and converted into electricity that is used to maintain our electrical appliances and equipment found inside our homes and businesses. The sunís heat energy is transferred into thermal energy which is then used to heat the air and water in our homes and businesses.
Both methods are becoming used more often as people are searching for a reliable source of energy that is safe for the environment. With gas prices being unstable and oil-producing countries being even more unstable, the need for alternatives sources of renewable energy has never been so important. The sunís energy is the perfect solution for many parts of the world. Even on cloudy days, solar energy is still able to be collected and converted into usable energy.
Photovoltaic Solar Panels
Photovoltaic literally means light (photo) and electricity (voltaic) and that is exactly what the solar panels photovoltaic do- convert light into electricity. Photovoltaic or PV is a technology developed to create electrical power by transforming solar rays into electricity. This is done with the use of solar panels photovoltaic.
These solar panels are placed on a buildingís rooftop or outer wall in a specific way that will allow them to absorb the most direct rays of the sun. The sunís rays are so strong that they can produce enough energy in one hour to provide the entire world with electricity for the whole year. With this powerful source of energy, solar panels photovoltaic has become the fasting growing source of renewable energy in the world.
Pros and Cons of Photovoltaic Solar Panels
There are many benefits that come from using solar panels photovoltaic. One of the most important benefits is that the energy can be produced in a very environmentally friendly way. This method does not emit any pollution into the air and leaves no damaging effect on the environment. Another essential benefit is that the sunís resource is readily available and will always remain a continuous source of energy. There is no need to ever worry about running out. And the best benefit yet it that this source of energy is free.
The cons of installing solar panels photovoltaic are that the initial cost of installation is very expensive. The high costs involved keeps many people from choosing to install solar panels. There are also parts of the world that do not receive enough sunlight throughout the year that would make using solar panels not very practical. These are issues that scientists are working on and at some point in the future they may be able to develop solutions.
