What is off-grid PV system?

Off-Grid Photovoltaic Systems Home Use

Off-grid solar systems will produce extra electricity during the day. This extra electricity is sent to the batteries for storage. The energy stored in the batteries can then be accessed at night or during cloudy days when the system is not producing energy.

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.
