How Do Solar Panels Work

It's all the rage today to have solar panels installed to heat up water in your geyser or to heat the water in your pool, but how many of us actually know how the technology behind solar panels works? A small number I am sure. If you are one of those people and also have a hunger for knowledge, read on.

Solar panels use the power of the sun to cause a similar process as that in chemical batteries. This process is the free flow of electrons.

The most basic element in solar panels is silicon. Silicon is a great platform for shifting electrons once it has been purified. Natural silicon atoms carry four electrons, but have place for a further four. The plates of solar panels are designed of this natural kind of silicon. The plates have a neutral charge when they are alone since each silicon atom requires eight electrons altogether to have a charge. Consequently they have to be combined with other elements that do possess a positive or negative charge.

For electricity to successfully flow, you need both a positive and negative charge. Phosphorus is frequently combined with the silicon to produce the negative plate and boron to produce the positive plate. The plates are thencoupled together with wires that are proficient at conducting electrical energy to form one panel made from a positive along with a negative half.

The completed panels are placed at a certain angle (negative on top) to capture the photons created by the sun's rays. These photons introduce energy into the negative plate. Once enough energy has been added, the extra electron which made the silicon-phosphorus combination negative breaks away from. The electron is drawn into the outer band of the silicon-boron mixture. This process lets out the energy source inserted by the photons and this force is converted to electrical power when it's taken by the conductive wire connections between the plates.

Despite the fact that only one escaping electron doesn't generate much electricity, the consolidated effort of millions of them crammed into the plate can power a small engine. Then again, the angle of the plate has to be just right or you will not likely get the most out of it, productivity can be cut in half by just a minor movement.

Solar panels usually do not produce much electricity, but any extra that there may possibly be could be kept in a battery and held for a rainy day (quite literally in this case). The more substantial the solar panels, the more electric power they will produce. Technology is constantly developing and trying to help with making them more efficient. At some point it may be attainable to power up a racing car with a solar panel the dimensions of an A4 piece of paper. Imagine having entire urban centers using the electricity provided by only a city block or two of solar panels as an alternative of requiring a roof enveloped in the panels for each family home!

Solar panels additionally save you lots of money on electricity bills and will recoup their cost in a few short years, where after you will have free electricity. Amazing, is it not?
