How Do Solar Panels Work

Photovoltaic cells are sandwiched between layers of semi conducting materials such as silicone.

How do solar panels work. Modules are designed to supply electricity at a certain voltage such as a common 12 volts system. Solar panels actually comprise many smaller units. Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity. Solar panels are composed of many smaller photovoltaic cells linked together.

Solar panels work by letting photons released by the sun knock electrons free from atoms and thus generate a flow of electricity. The current produced is directly dependent on how much light strikes the module. When you really break them down a solar panel is nothing more than a big sheet of glass over a metal frame with a patch of wiring that runs to your home s main electrical panel. There are three basic types of solar cells.

Pv cells also all have one or more electric field that acts to force electrons freed by light absorption to flow in a certain direction. Single crystal cells are made in long cylinders and sliced into thin wafers. The panel is encased in glass with an anti reflective coating that ensures that the solar panels get the most sun exposure possible. How do solar panels work.

Solar panels are made out of photovoltaic cells which is why generating electricity with solar panels is also called solar pv that convert the sun s energy into electricity. A solar panel is made up of numerous photovoltaic cells linked together. A number of solar cells electrically connected to each other and mounted in a support structure or frame is called a photovoltaic module. The panels are then either used as separate units or grouped into larger arrays.

Under the glass there is insulation that protects the components from humidity and regulates the temperature inside the panel to keep it operating efficiently. Solar panels work by absorbing sunlight with photovoltaic cells generating direct current dc energy and then converting it to usable alternating current ac energy with the help of inverter technology. How do solar panels work. The more panels you deploy the more energy you generate.

Ac energy then flows through the home s electrical panel and is distributed accordingly.
