What is on-grid and off grid solar system?

Being off-grid means you are not connected in any way to your grid’s power system or utility company. This is appealing because you are 100% self-sustaining your energy use.

Which is best on-grid or off grid solar system for home?

On-grid systems send excess power generated to the utility grid when you are overproducing. These are the most cost-effective and simplest systems to install. Off-grid systems allow you to store and save your solar power in batteries for use when the power grid goes down. It is meant to be entirely self-sustaining.
