Go Greener Tips

With the latest rise in energy costs many individuals have been seeking to alternative sources of energy. One of the best energy sources (our sun) is available for the taking. We just need to be able to harness it’s power. For those interested, under is a short history of how solar energy came to be.

The historical past of photovoltaic energy (aka. photo voltaic cells) began way again in 1876. William Grylls Adams together with a student of his, Richard Day, discovered that when selenium was exposed to light, it produced electricity. An electrical energy expert, Werner von Siemens, said that the invention was “scientifically of the most far-reaching importance”. The selenium cells were not efficient, however it was proved that light, without heat or shifting parts, may very well be converted into electricity.

In 1953, Calvin Fuller, Gerald Pearson, and Daryl Chapin, found the silicon photo voltaic cell. This cell truly produced enough electricity and was efficient sufficient to run small electrical devices. The New York Times stated that this discovery was “the starting of a brand new era, leading eventually to the belief of harnessing the almost limitless vitality of the solar for the uses of civilization.”

The year is 1956, and the first solar cells can be found commercially. The price however is way from the attain of on a regular basis people. At $300 for a 1 watt solar cell, the expense was far past anyone’s means. 1956 began showing us the primary solar cells used in toys and radios. These novelty objects were the primary item to have solar cells available to consumers.

.In the late 1950′s and early 1960′s satellites in the USA’s and Soviet’s space program had been powered by photo voltaic cells and in the late 1960′s solar energy was basically the usual for powering space bound satellites.

In the early 1970′s a solution to lower to value of photo voltaic cells was discovered. This brought the price down from $100 per watt to round $20 per watt. This analysis was spearheaded by Exxon. Most off-shore oil rigs used the solar cells to power the waning lights on the highest of the rigs.

The period from the 1970′s to the 1990′s saw quite a change in the usage of solar cells. They started showing up on railroad crossings, in remote places to energy homes, Australia used solar cells in their microwave towers to broaden their telecommunication capabilities. Even desert regions saw solar energy bring water to the soil where line fed energy was not an option!

Today we see solar cells in a wide variety of places. You may even see solar powered cars. There is even a solar powered plane that has flown larger than another aircraft aside from the Blackbird. With the cost of solar cells properly within everyone’s budget, solar power has by no means looked so tempting.

Recently new know-how has given us screen printed solar cells, and a solar cloth that can be used to facet a house, even photo voltaic shingles that set up on our roofs. International markets have opened up and photo voltaic panel manufacturers are now playing a key function in the solar energy industry.
