subject: Know More About Solar Panels [print this page] Solar power has already become a small part of our daily lives. We have learned to use the clean and sustainable power of sun to run the useful appliances. Solar panels have helped us power everything starting from a solar-powered calculator to a solar heated swimming pool. Before you decide to buy solar panels, let us understand what a solar panel is made up of? The main element that is used in making solar panels is pure silicon. When silicon is completely pure, it serves as an ideal neutral platform that facilitates transmission of electrons. Silicon also possesses some atomic-level properties, thus being an ideal element for creation of solar panels. So, now you know that if you buy solar panels what the technology consists of.
Silicon atoms can accommodate eight electrons in their outer band but carry only four in neutral state. In case of charged state two silicon atoms combine together to receive 4 electrons form each other and create a strong bond. This is completely neutral in charge and can combine for hundreds of years forming a silicon plate. This plate is used for making solar panels.
However, in the absence of any charge, no electricity can be produced. Therefore, Phosphorus (having five electrons in the outer band) is combined with silicon leaving one free electron. Thus the new plate combined with silicon and phosphorous is negatively charged. Now, solar panels need some positive energy in order for electricity to flow, which is created by adding boron (having three electrons in outer band) to it. This plate is positively charged.
Now the Silicon-Phosphorus plate and Silicon Boron plate is sandwiched with conductive wires to form solar panels. This is what you get when you buy solar panels from a retail website store. The amount of electricity generated by solar panels depends upon several things; its size, second is its angle of installation, its orientation and the amount of shading.
When you go to a shop to buy solar panels, you have to choose the size you are going to buy depending upon your requirement. An interesting thing is that you can store the extra power generated in chemical batteries for future use or opt to sell electricity back to your local utility.
