Alternative energy, like solar power, is high on the agenda at the moment. This means people are starting to think about how does solar power work?

Some of the queries people have are whether or not this is something they can include in their own lives and if it will effectively work to meet their demands. Although the sun has been put to work for us for many centuries, it is only recently that we have begun to fully understand and use its power. Therefore the answer is yes.

But what are the ways we can really use solar power? Solar panels are generally used to convert light into electricity. Many people have used this technology before and never realized it with solar powered calculators. In what way does this solar power really work?

The sun light is converted into energy by the solar panels which initially catch the light. One square meter of panels will harness enough power to run a hundred watt light bulb. It doesn’t seem like a lot to start with, but think about how many meters of free, unused spaced you have on your roof right now. Without taking up any usable space, solar panels allow you to harness the free power from the sun.

Another useful system are solar water heaters. This type of solar power works by using the sun to heat water. This is achieved by pumping water through pipes that are painted a dark color so as the pipes are heated by the sun, the water inside also warms as well. 90% of a home’s hot water is what some companies claim their water heaters can supply.

The only drawback is that the pipes have to be drained in the winter to keep them from freezing, but some companies have built in systems that make this easier to do.

A third kind of solar power are solar furnaces. A solar furnace is a group of mirrors that focus the sun’s rays. Does this type of solar power work effectively?

Focusing the sun’s rays enables you to achieve extremely hot temperatures. Scientists have used this kind of heating to achieve temperatures in excess of 5400 degrees Fahrenheit. If your not in a hurry this can of heating can be fantastic as their is not cost involved. But you have to remember is does take quite a while to heat thing this way.
