A grid solar panel system is simply a solar energy system that is connected to the electrical grid and, therefore, uses electricity from both the solar panel system and the electrical grid. Because of this, a grid-tied solar system doesn’t have to meet all of the electricity demands of the home.
If needed, the home can draw energy from the grid at times (such as on cloudy days or at night) when solar panels are not producing at full efficiency.
Likewise, if more energy needed than is generated by the solar panels of one home, that excess energy will be fed into the grid for use elsewhere.
