Injection into the Electricity Grid
A grid-connected photovoltaic system is made up of solar panels that produce direct current (DC), which is converted into alternating current (AC) by means of a solar inverter. When the solar energy generated is greater than the required, the surplus will go into the public electricity grid system (Edes) and will be registered (discounted) by the bidirectional energy meter. At times when the photovoltaic solar production fails to reach the projected energy (rain, dawn, night, etc.) then the public electricity grid will be used.
