How Does Solar Energy Work
Solar Cells Made Easy
by John F. McKnight Jr.
Alternative forms of power are becoming an important factor in the earth’s future, especially with all the worry and debates going on about global warming. Here are some facts on how solar energy works. A non-mechanical gadget, a solar cell, is made up of silicon alloys that help it convert energy into electricity.
Solar cells are made up of silicon alloys. These alloys help convert energy into electricity using this non-mechanic gadget. When energy and electrons hit the solar cell they can do one of three things. They can slide right through, they can reflect off of it, or they can be absorbed by it. The mount of photons absorbed inside of a solar cell determine its production of energy.
It depends on whether or not the surface of the photovoltaic call was given any special treatment. If so then that special treatment would make the surface of the solar cells more receptive to electrons that are just floating about. Meaning that they’ll migrate naturally towards the surface of the solar cell. When the electrons move away from their chosen spots then they leave a hole behind.
When the extra negative electrons move to the other side of the cell they make their new location negatively charged. The cell is turned into a sort of battery with one end being the polar opposite of the other. When both sides are connected by an outside force, it produces electricity and begins to release it.
A solar cell can be as small as 0. 5 inches and as large as 4 inches and can produce 1 through 2 watts of power. That isn’t enough to run our smallest appliances, or at least it wouldn’t be if solar cells weren’t usually sent out by the bulk. The signals sent by the now half positive, half negative cell are received by the weather station.
The solar cell will then send the electrical impulses to the weather station. In the station there’s an anemometer to measure wind, a pyranometer to measure solar energy, and a thermometer for temperature. Information from the signals is shipped to an acquisition system where the data is stored and calculated on a steady basis.
Solar energy is quick and efficient and because of that it is one way you can be sure to lower your monthly electricity bill.
