How Does a Solar Panel Work

You must be aware that solar panels are categorized into two types, these are; the ground mounted solar panel installations and the roof mounted solar panel installations. Both of them are technically similar as they are designed to absorb solar energy. However, the only difference that lies between them is their ability to offer adjustmentconvenience. Here, though, is how all solar panels work.

Solar photo-voltaic panels are lined with silicon crystals. When struck by sun’s rays, these crystals produce current that is carried through cables to be stored in batteries. The panels are usually held within an aluminium frame which is welded onto four support poles. During the installation process, these poles can be screwed onto the roof of astructure, or mounted on solid concrete slabs which are laid on the ground. The frames are tilted 30 degrees and oriented to the north for maximum solar energy absorption. “Thin film” panels are cheaper alternatives to photo-voltaic panels but their down side is that they are not as efficient in producing electricity.

Each silicon crystal has atoms that are bonded together by electrons. These electrons are shared between all atoms of the crystal. Sun’s rays hit the panel, the electrons in the bond absorb the light and gain a higher energy level thus they begin to move more freely/become excited. The moment they begin to move around the atom they start to generate electric current which continue to charge a solar panel battery.
