How To Solar Power Your Life


By Tim McDonald

For ages sunlight has been utilized by man. From being used in ancient temples for natural lighting to being converted to electricity for today's power hungry nations, the power of the sun has a number of uses.

So, how can solar power be used on a smaller scale at home as clean source of energy?

Currently, there are 4 general ways you can use solar power at home:

Solar Cooking:

A solar cooker is an extremely healthy, inexpensive and clean alternative to cooking your food. Though solar cookers have been used a lot to desalinize water in poor arid countries, many 1st world countries are adopting them in summer for cooking their food.

A solar cooker is made from a series of reflective panels in a parabolic shape that focus the sunlight on a box or pot, in which the food is cooked. It usually caters for up to five people, and can make a variety of boiled, roasted and baked dishes.

The one drawback of solar cooking is that it tends to take three to four times longer to cook food in. But if you weigh that against the unlimited power savings and its portability, having a little patience is not that bigger deal.

Solar Water Geyser:

Solar water heating has a number of uses, and thanks to technological developments, modern solar water heating systems can be used at home to completely replace conventional boilers or geysers.

As cold water is pumped through a solar collector, the pipes absorb the sun's energy, and heat the water, which is then stored in an insulated tank for later use. Usually the water can get so hot that it has to be mixed with cold water before it can be used.

Passive Solar Living:

What people do not realize is how much power they consume just to heat and light their homes. And if they could just see the benefit of using natural lighting and heating from the sun, they could save a lot of power and money.

With this form of solar power employment, sunlight is used as a natural heat and light source. The ideal passive solar home would have large double-glazed windows, with the length of the house facing the sun, and designed with materials that absorb the sun's light and radiate heat even after the sun has set.

And like the Romans used the sun to light up their temples, careful placing of windows and mirrors in our homes can increase natural lighting, helping us reduce the need for electric lighting.

A natural air conditioning solution would be to plant deciduous trees on the sun-facing side of your home. This would provide cool shade in summer, but allow warm sunlight though in winter.

A solar chimney can be installed for ventilation, where the air in the chimney is heated by the sun and rises, causing fresh, cool air to rush in through the home and up the chimney.

Solar Electricity:

Also known as photovoltaic power, many homes are starting to make their own power at home with solar electric panels. These panels are made up of small silicon cells and need to be directly aimed at the sun to be most effective.

As the sun's rays penetrate the solar panels, electrons in the cells become charged, creating a current that is stored in deep-cycle batteries. When electricity is needed, the stored power is passed through an inverter to change the DC to AC, which can then be used to power various household appliances or connected to the grid for net metering.

Other than providing you cheap, clean renewable power, solar electric panels have become affordable and simple enough for anyone to install at home. In fact, with the right information it is possible to make your own solar power for under $200, as compared to getting a professional installation for a couple of thousand dollars.

And these are the 4 ways how to solar power your home. If your are willing to learn how to use these methods at home, you will not only be living a greener life, but you will reduce your power needs and costs, receive renewable energy tax incentives, and lower the burden on our vanishing energy sources. So take the initiative and enjoy the sun's free, clean, abundant energy now.
