It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to change the electric current from DC to AC, as well as mounting, cabling, and other electrical accessories to set up a working system. Strictly speaking, a photovoltaic system converts light into direct current (DC) electricity.
A photovoltaic (PV) cell is a device that converts light into electric current using the photovoltaic effect. The basic principle of operation of a PV cell is that when light strikes the cell, some of it is absorbed within the semiconductor material. This absorption creates electronole pairs, which are quickly swept apart by the builtn electric field of the silicon cell.
This separation of charge carriers sets up an electric potential across the terminals of the cell. When the external circuit is completed, current flows and the photovoltaic cell delivers power.
How Do Photovoltaics Work?
Solar photovoltaics (PV) are devices that convert sunlight into electricity. They are made of materials called semiconductors, which can conduct electricity only under certain conditions.

How Much Electricity Can Solar Panels Produce?
Solar panels are devices that convert light into electricity. They are called “solar” because they use one of the most abundant and renewable energy sources in the world – sunlight. A single solar panel can produce enough electricity to power a small home appliance like a coffee maker. But to generate enough power for an entire household, you would need a solar array – a system of multiple solar panels.
The amount of electricity that a solar panel can produce depends on many factors, including its size, the angle of the sun, and the weather. In general, however, a typical solar panel can produce about kilowatt (kW) of electricity per square meter (m of surface area. So, if you have a solar panel with a surface area of m it could produce kW of power. But if you had an array of such panels, it could generate kW of power – enough to power average homes in the United States.
