Why do solar panels need to be connected to the grid?
The simple answer is that remaining connected to the grid allows your home to draw additional power when solar panels can't generate enough electricity, including nights and cloudy days.
What is a grid tied solar panel system?
When grid-tied, your solar panel system is connected to the grid via a bi-directional electricity meter.
