There are three types of solar panels: single crystal, poly-crystalline and amorphous silicon. Single crystal is currently the most efficient of the lot. Multi-crystalline solar power components are slightly less efficient than the single crystal. They are made from special crystals that are grown together in an ingot. Amorphous Silicon components are made by pouring a very thin layer of silicon directly onto a sheet of glass or plastic.
The main component of a solar panel, a solar cell, is created by using two thin sheets of impure silicon that are covered with a sheet of glass or plastic. The first silicon layer is called the n-type and the second silicon layer is called the p-type. When these two components come into contact they generate their own electric field. When this happens a barrier or diode is formed between the positive and negative sides. This allows electricity to flow in one direction between them.
Both sheets of silicon are covered with a conductive material to help fully harness the solar power. An anti-reflective coating is applied over the conductive material layer.
Solar light hitting the solar panel creates a solar pump which drives electrons from one silicon sheet to the other. The electron flow creates a current and the cells electric field creates voltage. The two together make solar power.
If you actually want to use this power then you will also need a solar power inverter or converter component. The power produced by the solar panel is direct current and the appliances in your home operate on alternating current. So the converter is necessary to turn the energy into something usable for your house.
The solar modules should be mounted on a well constructed holding structure and placed on your roof. In the case of your solar power components generating a surplus of power the power will flow back into the main power grid through the electrical utility meter, causing it to run backwards and giving you credit on your power bill. You can buy pre-made mounts or make the components yourself out of aluminum, angle iron, steel and wood. Each has its own advantages and disadvantages. Aluminum is lightweight and strong and will resist corrosion. Stainless steel is the most expensive option and can last for decades. While wood may be the easiest to work with it may have difficulty withstanding the weather elements over long periods of time.
So now you know a little bit about solar power components and how everything works together to produce this clean, green source of electricity.
