How Do Solar Panels Pv Cells Work

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.

How do solar panels pv cells work. Solar photovoltaic pv panels are based on a high tech but remarkably simple technology that converts sunlight directly to electricity. The solar cells that you see on calculators and satellites are also called photovoltaic pv cells which as the name implies photo meaning light and voltaic meaning electricity convert sunlight directly into electricity. Modules are designed to supply electricity at a certain voltage such as a common 12 volts system. A number of solar cells electrically connected to each other and mounted in a support structure or frame is called a photovoltaic module.

Photovoltaic technology is commonly attached to a panel. Each pv cell works by allowing a photon which is a particle of light to knock electrons free from atoms this action creates a flow of electricity. The current is captured and transferred to wires. In 1839 french scientist edmond becquerel discovered that certain materials would give off sparks of electricity when struck with sunlight.

The solar inverter converts the dc energy from your solar panels into ac energy. Each panel consists of several smaller components called photovoltaic pv cells photovoltaic means that it converts light into electricity. Loose electrons flow creating a current. Photovoltaic cells inside the solar panels absorb the sun s energy and generate dc electricity.

A solar photovoltaic pv cell turns sunlight into usable electricity in three general steps. It s an idea that has been around for well over a century. And these solar panels are connected to one another and mounted onto a frame. Solar cells produce energy in three steps.

Solar panels actually comprise many smaller units. This pv assembly is called a module and you can wire these modules together into an array. The electricity moves throughout your home powering lights appliances and anything else you wish to use it on. When you install solar panels on your house the pv cells convert sunlight into direct current dc and an inverter connected to the system is what converts direct current into alternating current ac which is the type of current needed to power your household appliances.

Light is absorbed and knocks electrons loose. Rays of sunlight photons are absorbed by the solar panels. A module is a group of cells connected electrically and packaged into a frame more commonly known as a solar panel which can then be grouped into larger solar arrays like the one operating at nellis air force base in nevada. Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity.
