Power goes solar

Renewable energy has definitely made a mark on the world. And perhaps the most popular renewable energy source is solar power. The concept of solar panels and solar power has been around for decades. But making solar panels is a process that is time consuming as the panels themselves are quite delicate. That is why it took a long time for people to start manufacturing and selling them.

The first usable solar cell was invented by an American company called Bell Industries in 1954. After the first development, the cells were used for minor purposes like toys. In 1958, solar cells were used on a satellite named Vanguard I. Using solar cells extended the total work time of the satellite’s mission and it also did not require the use of battery powered cells (which ran out of power quickly).

But at that time, solar cells were only being used for space related projects. Then, in 1969, a scientist named Elliot Berman realized that solar power can be used to generate electricity. Berman and his colleagues worked out how to get watt prices for solar cells from $100 per watt to $20 per watt. By 1973, solar cells were being placed together into panels and were being produced at $10 per watt and people could buy them at $20 per watt.

After Berman, improvements have slowly been made to reduce production costs down to $1 per watt, giving a better deal to customers. By the 1990s, large solar panels were being sold in the market; some panels being sold were at 5 and 6 inches in diameter. The advent of flat screen televisions led to large sheets of glass being used for panels. In 2009, silicon solar panels were introduced, making them the best and most popular solar panels being used. The public can Buy solar panels in Adelaide in Australia, Portland in America, Freiburg in Germany, and Shenzhen city in China among other cities to use solar power as a renewable energy source.

And the popularity continues to grow with every part of the world using solar power in some form. A few countries well-known for their use of solar power are Germany, China, United States, Japan, Italy, India and Australia. One can find some of the Best solar deals in Adelaide, Australia.
