The history of solar energy was discovered in 1876 by William Grylls Adams and his student Richard Evans Day, who produced permanent selenium under the influence of light. Selenium photovoltaic cells convert light with an efficiency of 1 to 2 percent into electricity.
We can trace all the energy consumed on our planet back to the source of the next star, our Sun. The history of solar energy is as old as the history of mankind itself. Over the last two centuries, we have begun to use solar energy directly to generate electricity.
1. History of Photovoltaic Energy
Photovoltaic solar cells have discovered that selenium produces electricity under the influence of light. The electricity expert Werner von Siemens explained that this discovery is of great scientific importance. Selenium cells were not efficient, but it has been shown that light can be converted into electricity without heat or moving parts.
In the 1980 solar power plants were first developed for Commercial concentrated. The 392 MW Ivanpah power plant is the world’s largest solar power plant focusing on the Mojave Desert in California, Also read 12 disadvantages of solar energy.
2. In 1953
Calvin Fuller, Gerald Pearson, and Daryl Chapin discovered a silicon solar cell. This cell produced enough electricity and was efficient enough to operate small electrical appliances.
The New York Times explained that this discovery was “the beginning of a new era that eventually led to the realization that the almost unlimited energy of the sun could be used by civilization.
3. The year was 1956
The first solar cells are available on the market. However, the costs are far from the reach of ordinary people. At 300 dollars per 1 watt solar cell, the costs were significantly higher than expected. In 1956 we were shown the first solar cells in toys and radios. These innovations were the first to make solar cells available to consumers, Also read Sources of solar energy.
In the late 1950s and early 1960s, solar cells were used to power satellites in the USA and the Soviet Union, and in the late 1960s, solar energy was basically the standard for supplying satellites with space. In the early 1970s, a way was found to reduce the cost of solar cells.
As a result, the price has dropped from $100 per watt to around $20 per watt. These studies were conducted by Exxon. Most oil platforms used solar cells to operate the alarm lights at the top of the platforms, Also read uses of wind energy.
4. The period from 1970 to 1990
A complete change in the use of solar cells. They began to emerge at level crossings, in remote areas where homes were supplied, Australia used solar cells in its microwave ovens to increase its telecommunications capabilities. Even in desert regions, solar energy was fed to the ground via water, where power line energy was not the solution.
Today we see solar cells in different places. You can see cars powered by solar energy. There is even a solar-powered airplane that, with the exception of the Blackbird, has flown higher than any other. With the cost of solar cells well below anyone’s budget, solar energy has never looked so tempting.
Recently, new technology has equipped us with screen-printed solar cells and a solar blanket, thanks to which we can also surround the house with sunshingles installed on our roofs. International markets have been opened up and solar module manufacturers now play a key role in the solar industry.
5. First solar house in 1973
Delaware University was responsible for the construction of the first solar building called Solar One. The system was powered by a hybrid source of solar energy and solar thermal energy.
It was also the first example of building-integrated photovoltaic (BIPV) systems – the system did not use solar modules, but integrated solar systems on the roof, similar to the design of the new Tesla roof product.
6. Solar-powered aircraft 1981
Paul MacCready built the Solar Challenger, the first solar-powered aircraft, and flew across the English Channel from France to Great Britain. In 1998, the remote-controlled solar airplane Pathfinder set a new altitude record with a height of 80,000 feet.
NASA broke this record in 2001 when it reached 96,000 feet with its rocket-free aircraft. In 2016, Bertrand Piccard completed the first emission-free flight around the world with Solar Impulse 2, the largest and most powerful solar aircraft in the world.
Since 2008, solar energy has become increasingly popular as a renewable form of energy, as its price has become affordable for a much broader market. Research and investment in solar technology are ongoing and there is no shortage of engineers and innovators. Solar module manufacturers continue to work on technological improvements to make solar modules more efficient and cost-effective.
Between 2010 and 2013, Chinese manufacturing companies began building large automated plants to manufacture solar cells and modules, further reducing module costs to $70 per watt.
In 2012-2015, solar energy systems were profitable for average U.S. households, and by 2015, more solar energy will be installed in the U.S. in more than 18 months than in the country’s collective history to date.
May 2015 Tesla Motor Company has announced the introduction of a product to store lithium-ion batteries at a price that makes storing solar energy produced during the day for use at night more economical for normal U.S. households.
December 2015 The US Congress has decided to extend the 30% federal tax credit by eight years to ensure the further development of photovoltaic solar systems in America.
