How Does Solar Electrical Panel Works



When thinking of going to the solar panel path, you probably have a vague idea of how the whole system works. Most people assume that the sun shines on the solar panel, there is a reaction with the materials and voila! You have the electricity. However, how the whole thing operates is a bit complicated. The solar panel is also known as photovoltaic which was first noted in 1839 by a French scientist named Alexandre-Edmond Becquerel. There have been various developments since then where different materials such as selenium, silicon, boron, and phosphorus have been used to produce electricity.

Every solar panel is made of individual photovoltaic cells where hundreds of these cells make a module, and the groups are then attached to the panel. Each of the cells consists of two layers that have silicon. The bottom layer is doped with boron while the top layer with phosphorus where the bonding of these materials creates an electrical charge. The top layer produces a positive charge and the bottom, layer a negative one. In between the layers is a P-N junction where the electrons keep on moving creating an electric field.  Sunlight is the main ingredient which makes the electrons jump and gets channeled into the right direction supplying the required circuitry for electric power generation.

There are different types of solar panels including the commonly known boxy type placed on roof arrays. Thin-film solar panels are readily available nowadays as they are cheaper and flexible; however, they are not rigid and efficient as the boxy type panels.
