How Do Photovoltaic Solar Panels Work

Solar panels actually comprise many smaller units.

How do photovoltaic solar panels work.

Today we ll talk about the performance and efficiency of solar panels. Strings of connected pieces increase the amount of energy to form larger units called panels or modules. The current is captured and transferred to wires. Then we ll dig deeper into the factors that affect the efficiency of solar panels.

A photovoltaic cell is an electrical sandwich. A solar photovoltaic pv cell turns sunlight into usable electricity in three general steps. Ac energy then flows through the home s electrical panel and is distributed accordingly. How do solar panels work.

Light is absorbed and knocks electrons loose. Let s get even a little more specific and a little more technical about how solar panels convert solar power into electrical energy. 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. The photovoltaic effect is a complicated process but these three steps are the basic way that energy from the sun is converted into electricity by solar cells.

Loose electrons flow creating a current. Pv cells take light or photons and convert it to solar electricity. How do solar panels work. Photovoltaic modules and arrays produce direct current dc electricity.

In 1839 french scientist edmond becquerel discovered that certain materials would give off sparks of electricity when struck with sunlight. Today s most common pv devices use a single junction or interface to create an electric field within a semiconductor such as a pv cell. Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity. When sunlight hits the solar panel pv cells produce direct current dc electricity.

The panel is encased in glass with an anti reflective coating that ensures that the solar panels get the most sun exposure possible. Solar panels capture sunlight each solar panel contains photovoltaic pv cells. It s an idea that has been around for well over a century. So let s get started.

Solar photovoltaic pv panels are based on a high tech but remarkably simple technology that converts sunlight directly to electricity. Lastly we ll give you insights into maximizing a solar panel s efficiency. How do solar panels work for your. A solar panel is made up of numerous photovoltaic cells linked together.
