Photo voltaic system
Photo voltaic system in short called PV (Photovoltaic), converts photons from the sun into electricity by photovoltaic cells based on semiconductors. This compares to the power stations where the thermal conversion systems, fuel burn.
Over the years, developed the technology used for photovoltaic systems and photovoltaic and improvements were made in very high frequency adjustments, mainly to promote the production processes. Today, the systems are very reliable systems successfully tested both in space and on Earth.
Obstacles that prevent the widespread installation of the system
The main obstacle to increase the use of PV systems is their high cost. However, over the years we have witnessed a decline in prices is an ongoing. Incidentally, there are sites that claim a distance of more than approximately 250 square meters out of the grid, the photovoltaic system and can be cost-effective photovoltaic much the property costs of connection to the electricity network and raise the monthly payments for the use of electricity.
Today, the comparison between the electrical energy cost and the cost of solar energy, also include the same costs "hidden" related to the use of electricity but are usually not taken into account in calculating the energy production cost. These hidden costs include the damage to the environment by energy source, the process, the use of traffic, and the need to handle waste disposal. Operating costs of the power system are substantially less than the costs associated with the solar system, and in many cases exceed them. And of course, the use of PV system is much less polluting of the other options.
Some will say to choose a solar system as a source of residential buildings, energy production, thanks to the ability of these systems to reduce electricity usage, since refrigerators, air conditioners, water heaters, dryers and washing machines - are power-hungry.
System costs over the years - United States
A study in the United States and examined the export costs of solar energy shows a significant drop in the average cost of these systems since 1998 till 2007, but since the cost has not changed.
Department of Energy researchers at Berkeley Lab who did the study say the decline in the overall cost of installing photo voltaic system due mainly to the decline in costs that do not belong to the system components, such as labor, marketing and operations. We can therefore assume that if you grow up deployment of PV systems across the country (almost certainly will cost more than the decline unrelated components than the prices of the components themselves), it will have any effect on accelerating the decline in costs.
The study examined 37,000 grid connection of photovoltaic voltaic system installed between 1998 and 2007 in 12 U.S. states. Is the average installation cost of the system decreased from -10.50 dollars per watt in 1998 to -7.60 dollars per watt in 2007. The number of installations of PV systems grew rapidly in the United States, where different countries offer incentives to expand the solar market. The purpose of the stimulus plan the U.S. government is helping propel the decline in the costs of PV systems, solar. One aim of this study was to offer reliable information on system installation costs over the years.
