Solar Power For Homes
Solar power for homes is one of the best ways that helps in the reduction of your electric bill. Even though a lot of people are aware of the benefits of having solar power for homes many of them are not sure whether this would be the best option.
During old times, the idea of solar power for homes was limited only to the use of the sun’s heat. Even before electricity was even discovered, ancient civilizations have made use of this heat for lighting and heating their homes especially during the cold, winter nights.
As days and years passed, more and more uses for the sun were discovered and better and more efficient methods of harnessing it were realized. Now, solar power has become a good and preferable idea for people who are aware of its benefits.
Solar power for homes is not possible if not for the invention of the solar or photovoltaic cell. It involves the application of the principle of photovoltaics to convert sunlight into electricity. It was first made by Charles Fritts using selenium during the 1880s. However, its efficiency of below 1 % has made it not ideal for use in commercial purposes.
This led to the development of the silicon type of solar cell by Russel Ohl in 1941 which become the basis for all types of solar cells that are used today. These cells were used in a wide variety of electronic devices. It can be found in most calculators, some cell phones and laptops, even watches and cameras. Also it was found to be a good source of back up power for orbiting satellites and space stations.
Today, aside from solar cells, the ongoing research and development on how to provide solar power for homes have devised other methods of harnessing the sun’s power. Solar updraft towers or solar chimneys utilize the method of using the sun’s rays to heat the air which is then converted by a turbine into electricity.
There are solar ponds which are actually salt water pools that can trap solar energy and thermoelectric or thermovoltaic devices which converts solar heat into electricity. These other methods are constantly being developed so that they can efficiently provide more solar power for homes.
However, in spite of the many ways in which solar power can be provided, it is still in the backseat as compared to conventional sources of power, like fossil fuels, that are being used today. This is because there still many hindrances to be overcome before the idea of solar power for homes everywhere could become a reality.
One of these hindrances is on finding a suitable location that is large enough and strategically located to collect as much sunlight as it can. There is also the high initial cost needed to convert conventional power systems to solar – powered ones. Nevertheless, constant advancements in technology have minimized some of these hindrances.
In spite of these hindrances, the application of solar power for homes is an idea that is still being encouraged today. This is because the use of fossil fuels in the generation of power has been the cause of much concern lately. The dwindling supply of these fossil fuels has increased the cost of power generation that it has made it hard for many people to afford electricity.
Also the use of these fossil fuels has led to the various environmental problems like pollution and global warming. With solar power for homes, all of these issues can be easily resolved once and for all. You can put a stop to your worries if you simply check on http://www.earth4energy.com. You will find a lot of valuable information on how to build effective solar power for homes that can last even for a lifetime.
