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. It measures the excess power you send to the grid when your solar panels produce more than you need, and the amount of energy you pull from the grid when your solar panel system doesn't generate enough.
Are solar panels off-grid?
If you are truly off-grid, you are not connected in any way to the local grid. That means there are no distribution wires from the power line to your home. You are entirely reliant on the electricity your solar panels produce to meet your energy needs, and there's no backup in case of a power outage or other issue.
