Solar Cells Made Easy
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.
Photons hold different amounts of energy that match up with the diverse wavelengths on the solar scale. When solar cells pull in a photon it can either reflect, pass completely through, or absorb into the mechanism. When the photons absorb into the solar cell, only then can they be used to make energy. After a certain amount of electricity is gained the solar cells begin to dislodge electrons from the atoms of the semiconductor.
Once energy is made, electricity is produced and released. During this, electrons become dislodged from atoms and depending on the sort of treatment done to the surface of the solar cell, then the more productive the cell will become to any electrons that are now floating free. The free electrons will migrate to the surface of the solar cell, which leaves empty spots where they were and changes the charge to positive.
Negatively charged electrons migrate towards the surface then the imbalanced charge between the two sides of the cell turns the cell into a battery. One side with a positive charge and the other with a negative so that when both sides are connected through external means, a plug for instance, then electricity is produced and begins to flow.
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.
The electrical distribution panel sends energy that’s received from all of this and combines it with the electrical current that’s already available in your home. It then routes the combined package through your building and helps power everything you could think of. If you want to lower your monthly electrical bill, then solar energy is a good alternative.
