The History Of Solar Energy

With the recent increase in energy expenses many individuals have actually been seeking to alternative sources of energy. Among the best energy sources (our sun) is easily available for the taking. We simply have to be able to harness it’s power. For those interested, listed below is a quick history of how solar power happened.

The history of photovoltaic energy (aka. solar batteries) started way back in 1876. William Grylls Adams together with a trainee of his, Richard Day, discovered that when selenium was exposed to light, it produced electrical energy. An electrical energy expert, Werner von Siemens, specified that the discovery was “clinically of the most significant value”. The selenium cells were not efficient, however it was shown that light, without heat or moving parts, might be converted into electrical power.

In 1953, Calvin Fuller, Gerald Pearson, and Daryl Chapin, found the silicon solar battery. This cell really produced enough electrical power and was effective adequate to run little electrical gadgets. The New York Times stated that this discovery was “the start of a new period, leading ultimately to the awareness of utilizing the nearly limitless energy of the sun for making uses of civilization.”

The year is 1956, and the very first solar cells are available commercially. The cost however is far from the reach of daily individuals. At $300 for a 1 watt solar battery, the expenditure was far beyond anyone’s means. 1956 began showing us the first solar cells used in toys and radios. These novelty products were the very first product to have solar cells available to customers.

In the late 1950’s and early 1960’s satellites in the USA’s and Soviet’s space program were powered by solar batteries and in the late 1960’s solar energy was essentially the standard for powering space bound satellites.

In the early 1970’s a way to lower to cost of solar batteries was discovered. This brought the cost down from $100 per watt to around $20 per watt. This research study was spearheaded by Exxon. Many off-shore oil rigs used the solar batteries to power the caution lights on the top of the rigs.

The period from the 1970’s to the 1990’s saw rather a modification in the usage of solar batteries. They started revealing up on railway crossings, in remote locations to power houses. Australia utilized solar cells in their microwave towers to broaden their telecommunication capabilities. Even desert areas saw solar energy bring water to the soil where line-fed power was not an alternative!

Today we see solar batteries in a wide range of locations. You might see solar powered vehicles. There is even a solar energy aircraft that has flown higher than other airplane with the exception of the Blackbird. With the expense of solar cells well within everyone’s spending plan, solar energy has actually never looked so appealing.

Just recently brand-new technology has offered us screen printed solar batteries, and a solar material that can be utilized to side a home, even solar shingles that set up on our roofing systems. International markets have opened up and photovoltaic panel manufacturers are now playing a crucial function in the solar energy market.
