These PV modules work exactly like the Grid Tied PV module except for the fact that they are self-contained systems with no connection to the grid. Their aim is to fulfill the electricity needs of the environment they are installed in. They work with a battery backup or a diesel generator to store PV energy generated.
A typical off grid solar PV module includes the following components:
- PV modules
- Inverter
- Balance of system – charge controllers and batteries for electricity storage.
