How do solar panels work.

Modules are designed to supply electricity at a certain voltage such as a common 12 volts system. 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. Under the glass there is insulation that protects the components from humidity and regulates the temperature inside the panel to keep it operating efficiently. 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.

How do solar panels work. This flow of electrons is a current and by placing metal contacts on the top and bottom of the pv cell we can draw that current off for external use say to power a calculator. Solar panels actually comprise many smaller units. The more panels you deploy the more energy you generate.

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. The panels are then either used as separate units or grouped into larger arrays. There are three basic types of solar cells. Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity.

A solar panel is made up of numerous photovoltaic cells linked together. Single crystal cells are made in long cylinders and sliced into thin wafers. A number of solar cells electrically connected to each other and mounted in a support structure or frame is called a photovoltaic module. Alone each cell generates very little power a few watts so they are grouped together as modules or panels.

Ac energy then flows through the home s electrical panel and is distributed accordingly. The current produced is directly dependent on how much light strikes the module. Photovoltaic cells are sandwiched between layers of semi conducting materials such as silicone. The panel is encased in glass with an anti reflective coating that ensures that the solar panels get the most sun exposure possible.

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.
