One of the most common ways to produce electricity is Solar Photovoltaic.The solar photovoltaic works by creating the photovoltaic effect using semiconductors. As the interest on solar energy and solar photovoltaic technology is growing, solar photovoltaic systems is used widely. The large investments on the conversion of renewable energy sources to electricity have evolved the technology of solar photovoltaic systems which makes it much cheaper and reliable.
How Solar Photovoltaic Works
Solar photovoltaic works simple by using solar Photovoltaic panels.All solar photovoltaic panels consist of a photovoltaic cell.This Photovoltaic device works to convert solar energy into electricity. A solar photovoltaic panel has 40 photovoltaic cells. As the Photovoltaic cells in solar Photovoltaic panels combine with each other, they form an array. You will produce more electricity when you have more arrays in your solar photovoltaic.
Components of a Solar Photovoltaic Cell
The solar cells in solar photovoltaic panels consist of light-sensitive semi-conductors. Most of these semiconductors are made up of silicon and are covered with light honing films.Now the science is simple, light consists of wave particles known as photons. Photons consists of energy and as light waves hit objects, these are absorbed by the objects. The semiconductors used by solar Photovoltaic panels absorb more and more of the photons to acquire maximum energy that will be later on converted to electric current.
As you may have known from Physics, due to the energy in the solar photovoltaic cells, atoms are charged. As the atoms are charged up, electrons begin to release. Solar photovoltaic cell intends to make the released electrons move from one side to another. Electric current is then created by these electrons through semiconductors.There are different factors that contribute in the strength of the current produced, including the films used over semi conductors, the type of solar photovoltaic cell and their protective coating. Only 20% of the photon’s energy is converted by most advanced solar photovoltaic cell into electric current.Most of the energy harnessed by solar photovoltaic cells is lost during the process of electron movement.
Why Solar Photovoltaic
Solar Photovoltaic also known as solar panel is a device that uses an array of solar cells to consume energy in sunlight and to convert sun energy into usable electric current. It is now usual to see houses, buildings, cars and even trains using solar photovoltaic panels for the conversion of solar energy to electricity.Another good reason to use solar photovoltaic to produce electricity is that it is emission free and noise free. Having a relatively cheap cost and an ecofriendly technology, Solar Photovoltaic is by means preferred by many.It is the best environmental source of energy that does not contribute in noise pollution and do not emit any harmful gas into our atmosphere. The maintenance cost of the solar Photovoltaic technology is just cheap for it doesn’t have any moving parts which avoids replacement every couple of months.
Due to stiff competition between solar photovoltaic manufacturers today, companies are putting efforts and money in producing more reliable, cheaper and capable solar PV systems.There is a growing trend in the commercial use of solar photovoltaic panels.The use of solar photovoltaic systems is growing by an average of 30% in last couple of years as people are showing more concerns over environmental pollution and seeking cheap electricity. As the cost of the solar photovoltaic systems is decreasing, the demand for it continues increasing. Its cost have decline due to factors like increased efficiency, technological improvement and large scale manufacturing.
Facts Regarding Solar Photovoltaic Industry
The large investments on solar photovoltaic projects have made the energy sector more profitable. The income produced by the solar photovoltaic industry has reached almost 40 billion dollars in 2009. In 2015, the revenue generated by the solar photovoltaic industry is estimated to reach 100 billion dollars.In 2009, the solar photovoltaic panels are used to generate 7.3 GW of electricity around the world, the figure that will be increase by five times in 2014.Another interesting factor is that the on-grid use of solar photovoltaic is growing by 20% while the off-grid use of solar photovoltaic is growing by 23%.This fact shows the interest of private sectors and common people in the use of solar photovoltaic panels in generating electricity.
Use of Off Grid Solar Photovoltaic Systems
The rise in the use of off-grid solar photovoltaic systems displays the interest given by the common people in renewable energy. Due to the cheap and green electricity offered by solar photovoltaic systems, people become interested on them.The increased use of solar photovoltaic panels in homes to power home appliances is also contributing in cutting the load from the national grid.This is the main reason why countries like Germany and Japan are giving financial incentives and are promoting the use of solar photovoltaic systems in domestic users.
Instead of depending on the national grid, many home owners power their houses using solar photovoltaic panels.The process is to install solar photovoltaic panels on the roof where you can have more sunlight. To save the supply of electric current at constant rate, batteries are used. Now, different varieties of solar photovoltaic systems are offered in the market. In the last couple of years, many new companies are manufacturing and providing solar photovoltaic systems to common users to power their homes, cars or other appliances.
