Solar panels, also known as photovoltaic (PV) panels, harness sunlight to generate electricity through a fascinating process. This renewable energy technology converts light from the sun into electrical power, which can then be used to power homes, businesses, and various electronic devices. This article will cover some of the basic steps.
The Basics of Solar Panel Operation
At the heart of a solar panel are photovoltaic cells, usually made from silicon. These cells are responsible for converting sunlight into electricity.
According to Live Science the process begins when photons, or light particles, strike the surface of the silicon cells. This energy excites the silicon’s electrons, knocking them loose from their atoms. The movement of these free electrons generates an electric current.
The Role of Photovoltaic Cells
Photovoltaic cells are arranged in a grid-like pattern within the solar panel. Each cell consists of two layers of silicon: a positively charged layer (p-type) and a negatively charged layer (n-type). When these two layers are placed together, an electric field is created. This field acts as a barrier that allows electrons to flow in one direction only, creating a direct current (DC) of electricity.
Conversion to Usable Power
The direct current generated by the photovoltaic cells is not suitable for most household appliances and electrical grids, which use alternating current (AC). Therefore, to make the electricity available for use, it has to be converted from DC to AC. This is done by means of an inverter, which is an essential component of any solar power system.
Efficiency and Installation
The efficiency of a solar panel system depends on several factors. This includes the quality of the panels, their angle and orientation, and the amount of sunlight they receive.
In many areas where solar panel installation is becoming increasingly popular, ensuring optimal placement is crucial for maximising energy production.
