How Solar Panels Work in 4 Simple Steps

Solar panels represent the wave of the future. They are champions of renewable energy and alternative energy sources; however, most are unfamiliar with the detailed processes behind solar energy production. Solar energy is so much more than simply harnessing the sun’s power, and this article will explain the complexities.

Step 1: Sun

Solar panels are activated by sunlight. Contrary to widely held belief, this includes the indirect sunlight produced on cloudy days. While direct sunlight is preferable, both indirect and direct sunlight will power solar panels. The photons, or the smallest possible packages of electromagnetic energy, are what truly activate the solar panels. Sunbeams are packed with photons, and the sun sends enough sunbeams in one hour to power the whole Earth. The complicated part is harnessing all this energy. This activation paves the way for the next step: the beginning of energy conversion.

Step 2: Solar Photovoltaics

Solar photons are converted into energy through a scientific process called the photovoltaic effect. According to Merriam-Webster Dictionary, Photovoltaic means of, relating to, or utilizing the generation of voltage when radiant energy falls on the boundary between different substances (such as two different semiconductors.) So, in simpler terms, think of using sunlight for energy when you hear the word. When producing energy, a voltage and current must be made. The photovoltaic effect is the process of generating voltage from a solar cell. This occurs as sunlight absorbs into the solar panels and voltage is added to create energy.

Step 3: Conversion

Once solar energy is created, it must be converted into electricity. Solar energy starts as direct current (DC) electricity, but the electricity used to power homes is alternating current (AC) electricity. DC electricity can only travel one direction within a circuit, while AC electricity can travel two directions within a circuit. An inverter, a device within a solar panel that can convert solar energy from DC to AC electricity, is used to make the energy usable. The inverter converts the electricity by taking the AC electricity and switching the direction of a DC input back and forth quickly, which thereby turns it into AC electricity. This conversion allows energy to flow in both directions within the circuit as opposed to just one direction.

Step 4: Enjoy

When the sunlight has been captured, absorbed, and converted into usable electricity, the process repeats itself and continues to power your home. Switching to solar energy is beneficial for the environment and your wallet. Any excess energy can be stored and even sold back to electricity companies through a process called net metering. Many states even offer tax credits that cover up to 26% of solar panel installation costs.
