Solar Energy Basics Explain Industry Growth and Increased Accessibility of Solar Power

Solar Energy Basics

Solar energy basics are fairly simple:  All light contains energy, including light from the sun.  Usually, when light hits an object, the energy turns into heat, like the warmth you feel while sitting outside on your patio.  But when light hits certain materials, the electrons in that material are activated and start “jumping around” which generates an electrical current instead. And that electric current can be harnessed for power if you can collect it and store it.

That’s where solar cells come in.  A solar cell is a manufactured device containing semiconducting materials that take the energy of sunlight and convert it into electricity.  This process is known as photovoltaics.  The word has two parts: photo, a stem derived from the Greek phos, which means light, and volt, a measurement unit named for Alessandro Volta (1745-1827), a pioneer in the study of electricity. So, photovoltaics can be literally translated as light-electricity.  And that’s just what photovoltaic materials and devices do:  they convert light energy to electricity using photovoltaic cells.  The PV panel – which is what you see on the rooftops of homes and businesses – is actually comprised of hundreds of these small photovoltaic cells that convert sunlight into electricity.

Simply put, a PV panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity.  Each photovoltaic cell is basically a sandwich made up of two slices of semi-conducting material, usually silicon — the same stuff used in microelectronics. A couple of other components of the cell turn these liberated electrons into usable power. Metal conductive plates on the sides of the cell collect the electrons and transfer them to wires. At that point, the electrons can flow like any other source of electricity. These photovoltaic cells work together to create a photovoltaic system to power your home or business.

Solar Energy Basics Drive Innovation

The basics of solar energy continue to fuel research and advances in solar technology.  Scientists are always working on new materials to incorporate into PV cells to make solar energy even more efficient and cost effective.  And, they are also exploring new ways to construct and install the PV panels and batteries required to generate and store solar energy.  Their success is evident:   According to the US Department of Energy, solar power is more affordable, accessible and prevalent in the US than ever before. Since 2008, U.S. installations have grown seventeen-fold from 1.2 gigawatts (GW) to an estimated 30 GW today, enough to power the equivalent of 5.7 million average American homes. Since 2010, the average cost of solar PV panels has dropped more than 60% and the cost of a solar electric system has dropped by about 50%.
