Solar Energy ... When will it be affordable for the average homeowner?
Introduction:
Global warming impact to our quality and cost of living is large and very catastrophic. Homeowners are well aware of the costs of increasing energy for heating, cooling and lighting their homes. The rising costs of oil and other fossil fuels are daily headlines. The insatiable demand for energy to fuel world growth guarantees that the limited cost of these fuels will increase. Political or economic forces that determine the rate of increase of fossil fuels. Furthermore, the growing cost of global warming fossil fuel is slowly being recognized.
The world is slowly beginning to understand the urgent need for renewable energy. However, each of these alternative energy sources brings major advantages and disadvantages. An example is wind generated energy. Energy wind is available to everyone and generates electricity competitively with fossil fuels. The technology is understood and easy to apply. However, there are large objections to a windmill in "my backyard". Moreover, the number of birds and bats that will be crushed with the wind power generation not a warming thought. Wind technology is a component of our energy solution. However, due to the above concerns, we other important solutions to meet our demand for energy sources.
This search leads to solar energy. The amount of solar energy striking our world in a day is enough to supply our energy demands for a year. Do not run out of this source in the foreseeable future. The main barrier to use Solar energy has been cost and convenience. For example, drying clothes in the dryer is easier than hanging clothes on a line outside, which hinders efforts the desirability of finding a more energy efficient. We can convert solar energy into electricity, but at a cost of capital. Greater acceptance and use of energy solar will lead to lower costs.
Solar Energy:
Energy from solar energy can be divided into two main categories:
Passive Solar: This technology ranges from clothes drying in the sun for solar Hot Water heating and many other passive techniques. All are important for our present and future quality of life. The technology is well understood and can be applied in economics and space conditions allow.
Energy assets Solar: One of the active solar energy technologies is converting solar energy directly into electricity. It is called photovoltaic or PV cell. This is a device that converts light into electricity by the photoelectric effect. The first working solar cells were built by Charles Fritts in 1883. These cells prototype was made of selenium and achieved efficiencies around one percent. The silicon solar cell was created in 1954. The solar cell has benefited from the development of semiconductor silicon.
Active Physics Solar Energy:
The physics of photon to electricity conversion is well understood by physicists. The basic model is of a photon of sunlight that strikes the cell material and excites electrons that emit electricity. This model is simple compared to the complexity of semiconductors today. The major variables are photovoltaic power generation cell material and impurities in the material of the cell.
Manufacturing Technology Active Solar Energy:
Mainly single crystal silicon of high purity has been used to generate photon conversion electricity. The manufacturing techniques of monocrystalline silicon and limited amounts of pure silicon impose a high cost for photovoltaic devices. The shortage of refined silicon world production has slowed since late 2004. This shortage persists to date, and growth has slowed PV. New materials are beginning to lay out what should reduce PV barrier materials.
Growth Efficiency Solar Energy Assets:
Since the invention of silicon photovoltaic in 1954, the cheapest prices on fossil fuels largely removed solar energy awareness. Annual growth in electricity generation by PV ranged from 10 percent to 20% during 1980 and 1990. The installation of photovoltaics worldwide reached 1,000 megawatts in 1999. Costs manufacturing of photovoltaic arrays has been down 3 to 5% in recent years. This fall in costs started to expand the use of electricity generation photovoltaics. Total peak power of installed PV was about 6,000 megawatts by the end of 2006. Installed PV is projected to increase to over 9,000 megawatts in 2007. The average retail cost lower large photovoltaic plants has been reduced from $ 7.50 to $ 4.00 per watt between 1990 and 2005.
PV materials have also been improving in recent years. The latest approach is to process discrete cells on materials cut crystalline silicon wafers from multiple ribbons that form thin films. This approach is the least expensive of known technologies. This group includes the technologies of amorphous silicon cells deposited on the stainless steel belt, cadmium telluride (CdTe) cells deposited on glass, dielenide copper indium gallium (CIGS) alloy cells deposited on substrates stainless steel or glass. The efficiency of these new materials are currently at 20%. Many researchers are working to improve efficiencies. Another advantage of new thin films is that they are flexible and are used in roofing materials.
Current trends in the generation of Active Solar Energy:
Commercial companies such as Google, IBM, BJ's Wholesale, Estee Lauder, Kohls, Target, Tiffany & Co., Wal-Mart to install solar photovoltaic energy. "Big box" discount giants to high-end commercial companies in the photovoltaic solar energy is finding acceptance in 2007. The most recent retail operator to join this trend is Macy's, which announced earlier this month that will install solar systems on 26 stores throughout California. These leaders are turning to solar power because it makes good business sense and supports their environmental initiatives. Creative financial arrangements allow these companies to pay the initial capital costs and the amortization of its loans to energy savings. So what does all this mean the owner of an average house? PV cost per kilowatt hour (kWh):
In the California market, where state incentives and net metering are in place, the prices of photovoltaic electricity is dipping below 11 ¢ / kWh, on par with some utility-delivered power. Moreover, according to the U.S. photovoltaic industry roadmap, electricity Sun will continue this trend and become competitive by 2010 most domestic markets. The outlook is very positive for photovoltaic generation of electricity. Once the capital investment is made, the cost of photovoltaic electricity is equivalent to fossil fuels and will continue to decline.
Cost of installation photovoltaic
The installation cost is the main barrier to be overcome for their widespread acceptance PV. Around 59% of global sales of solar products installed in the last five years are the applications that are linked to the mains. Prices of solar energy in these applications are 5-20 times more expensive than the cheapest source of conventional electricity generation. This premium is beyond the reach of the average homeowner.
Fortunately, approaching financial models exist to allow the consumer to finance PV solar installation and pay for the facility with electricity savings. In order that these financial models successful, federal and state incentives are needed and the installation must be connected to the mains. These connections allow the owner House to sell back electricity where available and receiving excessive amounts of electricity when solar conditions do not allow sufficient electricity. Only Fifty percent of our states have modernized for PV solar energy.
Berkeley, California is leading the way so that citizens saving electricity costs and meet environmental needs. Here's how your plan works. The owner hires a licensed installer of solar city, which determines the best solar system for the property, according to energy use. Most residential solar panel systems in the city cost $ 15,000 to $ 20,000.
The city will pay the contractor for the system and its installation, minus state and federal reimbursements, and add an assessment to the owner's tax bill to pay for the system. The additional tax will include administrative fees and interest, which would be less than what the property owner could obtain on their own, because the city safe for low-interest bonds and loans. The tax would stay with the property even if the owner sells, although the owner would have to out of the solar panels. The property owner would save money on monthly Pacific Gas & Electric bills because electricity generated by solar panels partly replace electricity delivered by utility. After the assessment expired, the solar panels, a simple technology that requires little or no maintenance, will partly replace PG & E electricity.
Berkeley's plan is a roadmap for the rest of the world that allows us affordable electricity and fulfill our responsibilities to the environment.
