On-grid means your solar system is tied to your local utility company’s system.. If you are producing more energy with your solar system than you are using, the excess energy is sent to your utility’s power company, it will allow you to build credit that you can cash out with at the end of the year.

Off-grid means your system is not connected with utility company.

An Off Grid Solar System will allow you to get off the grid energy anywhere  with Stand Alone Solar and Off Grid Batteries. If you are living in a remote or rural area ,the electricity isn’t available or is terribly costly to get connected to the grid, then an off grid solar system is a great solution as a stand alone power system or complete energy system for your home.
