Solar power is one of the most popular types of "green" energy, and the promise of harvesting energy from the sun is intriguing. However, even though it has been around for decades, solar technology is still a bit of a mystery to many people. To bring you up to date, Zelek Electric Co. in Old Lyme, CT, explains what solar energy is and how solar panels work.

What Is Solar Energy?

The sun is an enormous nuclear fusion reactor that bathes the earth with enough energy each hour that if we could capture and store it, it could satisfy the world's energy needs for an entire year. Although it is still in its youth, solar energy technology has evolved dramatically in the last 40 years. The photovoltaic panels needed to capture light and convert it into electricity are more efficient and less expensive than ever before, making solar an economically viable alternative to fossil fuels. It is an environmentally friendly energy source. It is renewable, plentiful, and does not emit greenhouse gases.

How Do Solar Panels Work?

Solar panels, or more precisely "photovoltaic panels," consist of two layers — positive and negative — of silicon, a well-known semiconductor material. When light strikes a panel, it excites the electrons within the panel and these electrons start to flow from one atom of silicon to the next along the layers, from negative to positive. This flow of electrons is called electricity, and this produced energy can be used to power devices, tools, and appliances. Any excess current can eventually be stored within a battery for later use.

Solar power is an increasingly efficient renewable energy, and solar panels are becoming ever more affordable.
