Solar Energy And Solar Cells:some Facts For You
December 22nd, 2009
How solar energy works is an essential piece of information to have when you’re talking about alternative forms of power. Made from silicon alloys a photovoltaic cell, or solar cell, is a non mechanical device used to convert energy directly into electrical power. Sunlight is made up of thousands and thousands of particles of energy which are photons.
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.
In order to produce energy, enough of the photons have to be absorbed so as to gain a certain amount of electricity. When that happens the electrons are dislodged from the atoms. Whether or not the solar cell has received a certain type of treatment, then the more receptive it will be to any wandering electrons floating around.
Electrons that will migrate naturally to the solar cell’s surface. Electrons moving from their chosen areas leave holes behind them and make that section of the cell positively charged. The same missing electrons, which are negatively charged, then move to the other end of the cell making that end negatively charged. What happens afterwards is that the cell is turned into a type of battery, with one extreme charge on side and the other on the remaining side.
The size of a solar cell can be anything from 0. 5 inches to 4 across and each one cell produces 1-2 watts of power. Not nearly enough power for even our smallest and simplest electronics. After its arrival at the solar cell it then heads to a weather station. The weather station will have an anemometer that measures the speed of wind, a thermometer for temperature, and a pyranometer measuring solar energy.
The station has anemometers to measure wind, pyranometers to measure solar energy, and thermometers for temperature. Information from all of these signals are sent to an acquisition system where the data can be analyzed on a scheduled bases.
Solar energy is quick and efficient and because of that it is one way you can be sure to lower your monthly electricity bill.
