Solar And Wind Power For Residential Purposes: Discovered


By Jim Martin

We live in an age marked by a heightened awareness of environmental issues. Everywhere, there is a conscious effort to switch to alternative modes of power generation that do not pollute the environment, are sustainable and do not rely on the consumption of our already dwindling reserves of fossil fuels such as coal and petroleum. Wind power, a popular alternative energy, dates back to the time of the early settlers who used the power of the wind for crushing grains with the help of gigantic windmills having 'sails' measuring 10 to 20 feet. However, it was not until 1979 when Danish engineers developed petite electricity generators fitted with light PVC blades capable of producing electricity that wind power became practically feasible. Those were the very first "Wind Turbines" which the world saw.

The potential of wind power was quickly realized by other nations and they followed in the footsteps of the Danish engineers. The following years saw a surge in the manufacture of wind turbine systems all across the US and the UK. Alternative energy such as wind power and solar power made it easy to save on electricity bills and also lessen the dependence on the local utility company or on the grid. However, wind energy also posed a few difficulties. The most serious complaint was due to the highly unpredictable nature of wind. Wind turbines need a consistent flow of wind to be really effective. Inclement weather and low wind speeds often result in severe disruption of power generation by the turbines. To add to the problem, there was the menace of noise. The turbines, themselves, contributed to noise pollution in and around the area where they were located and were often dubbed as 'roaring monsters'. This is one of the reasons why wind turbines are rarely seen in residential areas. However, in recent years, use of better bearings and intelligent redesigning of the turbines have reduced the noise to a great extent.

Another popular form of alternative energy is solar power, derived from the radiant energy of the sun. The discovery of solar energy has a very curious history. Calvin Fuller, Gerald Pearson and Daryl Chaplin of Bell Laboratories accidentally discovered the precursor to the modern solar cell in the form of silicon semiconductors while researching on the behavioral pattern of non-metals. This discovery was followed by the solar cell and everybody was amazed to discover how effective they were, especially when clustered together in the form of a solar panel, to generate electricity that could easily light up their homes like magic. Solar power became a hit instantly and very soon companies and manufacturers everywhere started doing business in solar panels, including manufacturing and installing them. The US government also began to endorse and encourage this new technology by offering incentives, grants and rebates for every installation undertaken within the country. One of the benefits that subscribers to solar power enjoy right away is a sharp drop in their monthly electricity bills which are slashed by up to 90%! The only drawback that solar power suffered from was its inability to work its magic after the sun went down.

In order to ensure uninterrupted power supply round the clock, and also to substantially reduce electricity consumption costs (in the form of electricity bills) one might follow the following steps.

Installing both solar panels and wind turbines for the home offers a foolproof plan to keep you covered for 24 hours. While the solar system generates power during the day, the wind turbines ensure seamless power generation at night.

Installing a battery bank with the system offers excellent protection against times when everything else fails. Batteries can easily store some amount of the generated power that can be used during times when both the systems are unavailable.

Get the system connected to the grid so that all surplus power can be sent back to the grid, helping you make a neat little profit from selling power to the utility.

It doesn't take much to make money from the system. With both units running simultaneously, the consumer will not only need any current from the grid but will actually be able to sell back to it his or her own generated current.

There is a growing need for solar and wind power for residential use. Their popularity is continuously increasing. Even though there are still a few technical glitches, they are like nothing that cannot be resolved in the near future.

People across the world now know the advantages of installing a solar or a wind power system at home. By doing this you are now only contributing to clean up the environment, but the benefits are financial as well as you can reduce your power bills. So would you like to set up such a system? Take help from a manual that will help you install it step by step by showing you where to set it up, how to do it, how to wire the system, where to get the parts and the batteries from and will inform you about the safety instructions too.
