What does the principle of photovoltaic panels mean
Photovoltaic panels are devices that convert sunlight directly into electricity. Each panel contains dozens of solar cells made from semiconductor materials, most commonly silicon, that generate an electrical current when exposed to light. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. 5 volts, so dozens are wired together into the panels you see on rooftops. These electrons flow through a circuit and produce direct current.
