The first uses of solar energy that we know about were as far back as 400 BCE. The ancient Greeks started making their homes on the basis of where the sun’s rays could warm the house during the cold winter months, and this is the first use of solar energy we know about. It could also be considered an early form of heating.
It is also said the ancient Greeks and Romans used a form of magnifying glasses* to light fires and torches, especially for religious ceremonies.
*Magnifying glasses, although slightly different from today’s sleek models, have also been around for a very long time, with the oldest model found from 424 BCE. These were glass spheres filled with water (you can try looking through a glass or bottle of water to read something – it does magnify the writing), but it was all they had to magnify the desired object back then. They were also good for focusing the sun’s rays onto something to start a fire.
Small Discoveries Of Solar Energy Leading To Today’s Uses
Getting to the point we are at today where a home solar system can effectively heat a home, produce hot water, and run electrical gadgets, was a long and windy road filled with small discoveries rather than a sudden breakthrough. This means tens of people were involved in making the solar power process work better and more efficiently. In some cases, this was a matter of tweaking a discovery to make it more effective, and in others of making the discovery in the first place.
Mentioned here are only a few of these contributors, along with what they discovered.
- Although often left out of lists of achievements relating to solar power, a Swiss scientist called Horace de Saussure made a solar energy collector in 1767, nicknamed a “hot box.” Although little is said about this invention, it, or something very similar based on it, was used by the astronomer John Herschel for cooking food while on an expedition in Africa – this would lead you to believe the hot box did work.
- The discovery that it was possible to use the sun to create electricity was made by a French Physicist called Antoine-Cesar Becquerel in 1839.
- In 1860 another Frenchman, Auguste Mouchout, believing even way back then that his country was depending too much on non-sustainable fuel, set out to create a sustainable alternative, and within five years, he had made a solar-powered steam engine. (It makes you wonder why no one in the intervening years had the same thought until only a few years ago when panic hit.)
- The first patent for a solar cell was granted in 1888 to Edward Weston, an English chemist living in America.
- For a while, the “inventions” were limited to bettering existing ideas, such as using different substances to coat solar cells, so they were more efficient at converting light into electricity.
- In the 1920s, solar water heating systems were used in some areas in America.
- The first photovoltaic cell was made in 1941 by the American Russell Ohl.
- In 1954, Bell Laboratories developed the first modern silicon solar cell, much as we know it today.
- In 1957, AT&T got a patent for the first solar battery.
- In 1962, Telstar, the communication satellite, was solar powered.
From that point onwards, solar power didn’t look back and is becoming more and more popular. It is one of the most sustainable fuels available.
You can have just about anything driven by solar power, including a car (there was even talk about solar roads, see the section on solar roads for more details), but solar lights are perhaps the most common solar devices. As these became more readily available and more affordable, many house owners bought an array to position outside their homes. These offer not only free light, but also a light that requires no wires or lines and therefore no installation. This combination proved very popular and continues to do so today.
