Truths Regarding Solar Photovoltaic
A common way to produce electricity by converting solar energy to current electricity is Solar Photovoltaic. Using semiconductors, solar photovoltaic creates photovoltaic effect. 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 Functions
The process revolves around the simple principle of converting solar energy into electric current using solar Photovoltaic panels. Solar photovoltaic panels contain photovoltaic cell. The work of this Photovoltaic device is to convert solar energy into electricity.A single solar photovoltaic panel consists of almost 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 PV cells in solar photovoltaic panels consist of light-sensitive semi-conductors. Semiconductors consists 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. To harness maximum energy, semiconductors used by Photovoltaic panels absorb more and more of photons which in turn be converted to electric current.
As you may have known from Physics, due to the energy in the solar photovoltaic cells, atoms are charged. When the atoms are energized, electrons begin to release.The solar photovoltaic cell is designed in a way that released electrons flow from one side to another.These flowing electrons through semiconductors create electric current.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.Even though, the process looks like simple and straightforward but the fact is that the most advanced solar photovoltaic cell can convert only 20% of the photon’s energy into electric current. As the electrons move, the energy harnessed by the solar photovoltaic cells is lost.
Reasons in Using 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.Today, you can find houses, buildings, cars and even trains that use solar photovoltaic panels to convert solar energy into electricity. The production of electricity in solar photovoltaic is emission free and noise free as well.The two common reasons why the usage of solar Photovoltaic is preferred is the cheap cost and its ecofriendly technology. It is indeed the best source of energy available for it does not damage our atmosphere.The technology of solar Photovoltaic is without any moving parts so the maintenance cost is very low as you do not have to replace any parts after every couple of months.
Companies today are competing in producing consistent, cheaper and capable solar photovoltaic 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. The cause of the increase in the demand for solar photovoltaic systems is the decline on its cost. Its cost have decline due to factors like increased efficiency, technological improvement and large scale manufacturing.
Statistics about Solar Photovoltaic Industry
Big companies in the energy sector are investing huge capital on solar photovoltaic projects as the demand and need is rising all over the world, as well as the sector is becoming increasingly profitable. The income produced by the solar photovoltaic industry has reached almost 40 billion dollars in 2009.With the current growth, the expectations are that the revenue generated by the solar photovoltaic industry will cross 100 billion dollars in 2015. The 7.3 GW of electricity worldwide generated by solar photovoltaic panels is predicted to increase by five times in 2014. The growth on the on-grid and off-grid use of solar photovoltaic is increasing by 20% and 23% individually.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.The rising electricity prices and increased awareness about our environment is building an interest in people towards solar photovoltaic systems that offers both, cheap electricity and green electricity. The use of solar photovoltaic panels in homes helps in lessening the national grid’s load. This is why countries encourage the use of solar photovoltaic systems in domestic users.
Solar photovoltaic panels are now used by many as an alternative to the national grid when it comes to powering houses.The process is to install solar photovoltaic panels on the roof where you can have more sunlight. Using batteries, electricity can be stored to retain the rate of electric current.Today, there is a range of solar photovoltaic systems available in market that varies in price, complexity and size. 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.
