How Do You Produce Electricity From Solar Energy


The answer to the question of how do you produce electricity from solar energy is fairly easy to understand once you have a slight knowledge of the subject.
Before you are able to produce electricity through solar energy, there needs to be some form of solar cell or panel.The solar panels are made of a semi-conductive material, the most common material is silicon.The semi-conductive material contains electrons which are quite happy just sitting there.When photons (contained within the suns rays) hit the solar cells, the electrons absorb this solar energy, transforming them into conduction electrons.If the energy of these photons is great enough, then the electrons are able to become free, and carry an electric charge through a circuit to the destination.Any electrons that do not receive enough energy simply warm up, which heats your cell or panel, resulting in lowering the efficiency of the cellThe lowering in efficiency is down to two main factors and they are; that the cell is not working to its full potential (e.g. some electrons may be lost), the second factor is when the electrons release heat, the panel also becomes warm, interfering with other aspects of the solar cells.
