Solar energy is converted into electricity using an electronic device called "solar cell" and thanks to a physical phenomenon known as photovoltaic effect. The cells are connected and assembled together forming a pv module or panel that absorbs the solar radiation and generates electrical energy.
The solar panels, known as well as pv modules, and the inverters are the core of a solar system. The panels generate direct current electricity (DC) and the inverter converts it in alternating current (AC) usable to make the household electrical appliances work normally or to feed the electrical grid.
PV systems can be grid connected (interacting with the local electrical grid) or work as stand-alone systems (autonomous).
Examples of some applications of photovoltaic's are the following:
