Everyone knows that solar panels are intended to produce electricity that will then power your home or business. Now, the question is how do solar panels generate this electricity? We’ve provided a fairly simple breakdown so you can have a better idea of how they work.
Solar photovoltaic cells contain a positive and negative film of silicon placed under a thin piece of glass. As sunlight photons break down these cells, electrons are pushed off the silicon allowing these negatively-charged free electrons to be drawn to one side of the silicon cell. An electric current is then gathered by wiring the individual solar panels together to form a solar photovoltaic array. Thereafter, electricity that is produced is called direct current (electric charge flow in one direction) and has to be modified to alternating current (electric charge flow that reverses direction periodically) that is suitable for home and business use.
