. On-Grid Solar System
An On-Grid Solar System is connected to the electricity grid. Solar panels generate electricity, and extra power can be exported to the grid.
- Battery: Usually not required.
- Works: With the electricity grid.
- Advantage: Lower installation cost.
- Disadvantage: Usually does not work during a power cut without special backup equipment.
2. Off-Grid Solar System
An Off-Grid Solar System works independently of the electricity grid. It uses solar panels, a solar inverter, and batteries to store electricity.
- Battery: Required.
- Works: Without a grid connection.
- Advantage: Can provide electricity in remote areas.
- Disadvantage: Higher installation cost because batteries are needed.
Main Difference: On-grid systems are connected to the electricity grid, whereas off-grid systems use batteries to provide power independently.
