The increase in the use of photovoltaic solar systems surprised many when it showed more than 100% growth in 2010 as the use of photovoltaic solar systems increased from 7.5 GW in 2009 to 18.2 GW in 2010. Only three countries, namely: Germany, Japan and United States, hold 90% of the overall photovoltaic solar systems, but it still made them the fastest growing energy technology worldwide.
Even during the first time that Japan used photovoltaic solar systems, no expectations were made as if they will be the fastest growing technology. Today, the major country in the use of Photovoltaic solar systems is Germany. PV (Photovoltaic) industry in Germany is generating over ten thousand jobs in distribution, installation and production of Photovoltaic solar systems. To encourage the masses in using off grid electricity, many EU countries started financing in photovoltaic solar systems.
What is Photovoltaic Solar System Consist of?
Photovoltaic solar systems are made up of numerous solar panels which consist solar cells that convert solar energy to electric current. The components contained in photovoltaic solar system can produce, store and supply electric current. A photovoltaic solar panel needs an array of solar cells since a solar cell alone can only generate a low voltage of about 0.5V.
How Photovoltaic Solar System Produces Electric Current
Silicon semiconductors are used by photovoltaic solar systems in converting solar energy to electric current. During exposure to sunlight, the atoms in the semiconductors become energized and begin losing their electrons. These electrons flow through a proper channel thus creating a direct current (DC). The inverter connected to the photovoltaic solar systems then converts the direct current into alternate current (AC). Through electrical wiring, AC will be attached to the main power supply of the house.
Manufacturers of photovoltaic solar cells are trying their hardest to make the cells more efficient since their efficiency is still only 20%. With the increased efficiency, the cost of photovoltaic solar systems may further decline and it can also decrease the size of photovoltaic solar panels used in PV systems.
What are the Applications of Photovoltaic Solar Systems
As the technology of photovoltaic solar systems is now considered the leading consumer energy source, the research and development has paced up in the last few years. Extending the influence of the photovoltaic solar systems to the common people is one of the goals that its manufacturers want to do. Many companies started investing large amounts in making photovoltaic solar systems convenient to common people since the off grid use of these had increased.
Companies offer separate photovoltaic solar systems. There is no need to have a connection with the national grid for electricity or standby generators. They have a full capacity to power homes, cars or any other remote building. Another common application of photovoltaic solar panels is their use in solar cars. The solar energy-powered train in Germany shows the country’s interest in the use of photovoltaic solar systems.
The Pros of Using Photovoltaic Solar Systems
1. As you use photovoltaic solar systems for your own electricity, there is no need to worry about the cost of electricity.
2. Being attached to the national grid is not a problem to worry about. Building your house at a remote place will not be a concern anymore.
3. You can help contribute to the society by using photovoltaic solar systems since it reduces carbon emission in the atmosphere. The photovoltaic solar systems are by far the only source of clean energy with zero carbon emission and no noise pollution.
4. Even though the weather is cloudy, photovoltaic solar systems can still produce electricity. This means that you can have a continuous electricity.
5. Replacement of the photovoltaic solar system’s components is not a problem for they are not running.
6. By installing photovoltaic solar systems to power your house, you are contributing in cutting the load of the national grid. This allows your government to meet the rising demands of energy more easily and provide electricity to the industrial sector on full scale.
7. Companies are now offering 25 to 40 years warranty for photovoltaic solar systems, The photovoltaic solar systems are your long term solution for uninterrupted power supply.
Photovoltaic Solar Systems Toward a Bright Future
The sun solar system industry have a bright future ahead of it. Many people invest in PV industry since photovoltaic solar systems promise growth. Photovoltaic solar systems have been regarded as the fastest growing source of energy due to its amazing features. The competitiveness of photovoltaic solar systems heighten. It is now tough for the investors to keep up since many business models of photovoltaic solar systems evolve.
Photovoltaic solar technology is now essential in meeting future energy demands worldwide. Photovoltaic solar technology is soon to be the fundamental element of electrical system in the EU. The off grid continues to grow since many offers financial incentives for the installation on photovoltaic solar systems to local people. This permits common people to produce their own electricity rather than rely on national grids. The photovoltaic solar technology is becoming an increasingly profitable sector for investors offering strong financial returns.
