The technology to derive substantial electricity using sunlight has existed since mid-1950, when the first solar cell was created by Daryl Chapin, Calvin Fuller, and Gerald Pearson at Bell Labs – developed the first solar cell capable of generating enough power sun to run everyday electrical equipment. A silicon solar cell which was produced was 6% efficiency. They were able to increase the efficiency of one percent.
Anyone who is aware of the possibility of exploiting sunlight into electricity just remembered Jr. High School science class that the electricity produced by a solar cell is good if the sun shines directly on the solar cell PV.
With the basic knowledge that the direct product of (not hunting) ongoing solar cells is clear that there are two costly obstacles that stand in the way of practical solar energy: 1) How to convert the DC current ( DC) so that it can be used in common household alternating current (AC) and 2) how virtually store energy for use when needed after sunset or disappeared behind the clouds.
When solar technology has developed and become less expensive to produce, the infrastructure of our nation had already established and built around the level of 110 volts AC and 15 amps. A major expense for the use of solar cells is the requirement for expensive inverters to convert DC to AC.
With the help of Exxon Corporation in 1970, a much less expensive solar cell was developed by Dr. Elliot Berman. Its design has reduced the price of solar electricity from $ 100 per watt to $ 20 per watt. Although still expensive, it was a giant step in the feasibility of using solar energy practice
In 1976, the Research Center of the NASA Lewis began installing the first of many PV systems on all continents of the world except Australia. These systems have powers to vaccine refrigeration, room lighting, illumination of the medical clinic, telecommunications, water pumping, grain milling and classroom television. The project took place from 1976-1985 and again from 1992 until its completion in 1995. By the time the project, 83 autonomous systems were in place was completed. These areas where systems were installed were clearly lacks practical systems on the grid.
In July that year, management of research and development of energy in the United States, which was the predecessor of the Department of Energy of the United States launched the Institute for Solar Energy Research. In 1977, total production of photovoltaic manufacturing exceeded 500 kW (kilowatts). It was only enough power to illuminate 5000 light bulbs of 100 watts.
In 1982, the power plant first stop megawatt PV (photovoltaic) went online in Hisperia, California. System capacity was 1 MW and was developed by ARCO Solar. The Department of Energy of the United States and a consortium of industry began to operate Solar One, a project of central transceiver demonstration of 10 megawatts in California has established the viability of the systems on the tower. During this same time, an Australian named Hans Tholstrup drove the first solar car – quiet achiever – about 2,800 miles between Sydney and Perth in 20 days. That was 10 days before the first car made essence. Tholstrup is now the founder of a race car world class Solar World Solar Challenge in Australia.
Two more significant in 1982 that shaped the history of solar energy; Germany’s Volkswagen began testing photovoltaic systems mounted on the roofs of Dasher trucks that have generated 160 watts of electricity for use in the ignition system; Residential Experiment Station and southeast of the Florida Solar Energy Center began supporting the program of the Department of photovoltaics United States in the application of systems engineering. Worldwide, the photovoltaic production and exceeded 9.3 megawatts.
In 1986, the world’s largest solar power plant was commissioned in Kramer Junction, California. The solar field contains rows of mirrors that concentrate the sun’s energy in a pipe system circulating fluid heat transfer. The heat transfer fluid, used to produce steam, feed a conventional turbine to produce electricity. While
Researchers at the University of South Florida have developed a thin layer solar cell efficiency of 15.9% of cadmium telluride, breaking the barrier of 15% of this technology, a 7.5 kilowatt prototype antenna system includes a hub tip membrane stretched began operating in Florida.
The first solar station to distribute electricity produced from solar panels was Pacific Gas & Electric (PG & E) in 1993, in Kerman, California. The National Renewable Energy Laboratory (formerly the Institute of solar energy) has completed construction of its research on solar energy and has been recognized as the best of all buildings in the US government in the economic world power.
In 1994, the first solar dish generator using a free-piston Stirling engine is connected to a power grid and the National Renewable Energy Laboratory developed a solar cell of gallium indium phosphide and gallium arsenide. This cell development was first to reach a higher conversion efficiency than thirty percent.
Two years later, but not in the US, but worth mentioning, a solar airplane, the Icare, flew over Germany. The wings and the wings and tail were covered by 3,000 solar cells with high efficiency. Total area was 21 square meters.
The Department of Energy of the United States and a consortium of industry begin to operate Solar Two. – An update to the concentration of the solar power tower Solar One Until the end of the project in 1999, Solar Two has shown how solar energy can be stored effectively using molten salt economically so that the power can be generated even when the sun does not shine; but also stimulate commercial interest in the molten salt Power Tower Technology [http://www.energylan.sandia.gov/sunlab/snapshot/stfuture.htm#tower]
On August 6, 1998, a plane solar remote control “Pathfinder”, set a record altitude of 80,000 feet after his 38th consecutive leak in Monrovia, California. This is higher than any propellers work to date.
The tallest skyscraper in the city, which was built in the years 90-4 Times Square in New York – has more features than any other energy efficient commercial skyscrapers. The building has photovoltaic panels integrated into the 37th (BIPV) through 43rd floors of the south and west facing facades to produce a part of the energy of the building.
The National Renewable Energy Laboratory (NREL) and Spectrolab, Inc. has developed an efficient solar cell of 32.3%. This highly efficient cell results from a combination of three layers of photovoltaic material in a single cell. This cell was more effective and convenient when used on devices with lenses or mirrors to concentrate sunlight. These concentrator systems [http://www.environment.gov.au/settlements/renewable/recp/pv/pubs/pv2.pdf] are mounted on followers still maintain their edge at the sun. NREL also produced a track record of success in the niche of thin-film cells. It has increased efficiency over 1% to 18.8%.
Today, with oil prices above $ 126 / barrel, more and more people are looking for alternative sources of energy to meet its energy needs. Using cooking oil as fuel for diesel vehicles, the use of wind and solar energy in the residential sector, where the people realize that they can no longer rely on the Middle East, or even their own governments to regulate properly energy.
People should be proactive in their efforts to provide energy. Who knows, it may be possible that one day we invented cars with remove and replace the batteries, similar to warehouse forklifts. Spare batteries that are charged through the solar panel during the day to replace the battery last night. Just in time for the trip the next working day.
Duckett gene was interested in solar gadgets with their first credit card sized, solar calculator bought at Radio Shack in 1979 is now grown up and he knows what he wants to do with his life, which combines solar forward to in The USA. to develop energy sources that are independent from foreign sources. That’s why he founded [http://www.gnpsolar.com] His intention is to disseminate information about solar energy and practical applications to as many homeowners and business owners as possible. He believes that we must not only as a country, to eliminate the need for foreign oil, but we must also reduce or eliminate dependence on the power grid. When people give up self-sufficiency for the daily needs in the wholesale market, then they put in a vulnerable position. He never in the history of man was so dependent on his government (s) and, in some large companies measure) for the needs of daily life. There is a good reason that the ancestors of the United States to limit the powers of government. These reasons are still valid today.
