Solar’s simplicity is part of its attraction. Solar energy systems are easy to install and easy to maintain. And solar’s ability to save you money is straightforward.

How Solar PV Technology Works

 

Solar photovoltaic (PV) technology has been in use since the 1950s, when Bell Labs developed a silicon cell that could capture enough solar energy to run electrical equipment. Modern solar energy systems harness this technology to convert sunlight into electricity that can power our homes, businesses and more. Solar panels (also called “modules”) are made up of multiple cells on a rectangular panel. These cells are made from semiconducting material, usually silicon.

  • When sunlight hits a solar panel, the cells in the panel absorb photons from the sun and convert them into electrons, which flow through the cell as electrical current. That current then flows from the cells to inverters under the panels which convert the energy from direct-current (DC) electricity into alternating-current (AC) electricity.
  • The electricity flows through your electric panel and into your home or business for use as needed.
  • When you make more solar electricity than you need at the time, the extra electricity flows into the grid, first being measured by the electric meter on the side of your house.
  • The electricity then flows into the utility grid for use by others.
  • Electricity from the utility still flows from the grid into your home when needed to supplement your solar electricity.
