On-Grid vs Off-Grid Solar which one fits you?অন-গ্ৰিড বনাম অফ-গ্ৰিড সৌৰ which one fits you?
On-grid systems connect to the electricity grid and use net metering; off-grid systems run independently on batteries. Here's how to choose.On-grid systems connect to the electricity grid and use net metering; off-grid systems run independently on batteries. Here's how to choose.
Side-by-side
| Factor | On-grid | Off-grid |
|---|---|---|
| Grid connection | Connected | Not connected |
| Battery | Not required | Required |
| Net metering | Yes, where eligible | No |
| Backup during outage | No | Yes |
| Upfront cost | Lower | Higher (batteries) |
| Maintenance | Lower | Higher (battery care) |
| Best for | Reliable grid premises | No grid or unreliable grid |
Choose on-grid if…
- Your grid supply is reasonably reliable
- You want the lowest cost and least maintenance
- You want to benefit from net metering
Choose off-grid if…
- There is no grid connection
- Outages are long and frequent
- You need genuine independence
In between: hybrid
If you have a grid connection but also need backup, a hybrid system combines solar, battery and grid — savings from solar with power when the grid fails.

Which is better, on-grid or off-grid?Which is better, on-grid or off-grid?
Neither is universally better — it depends on your grid. For a reliable grid connection, on-grid is simpler and cheaper. For no grid or frequent long outages, off-grid provides independence. A hybrid system sits between the two.Neither is universally better — it depends on your grid. For a reliable grid connection, on-grid is simpler and cheaper.

Can I export power with off-grid?Can I export power with off-grid?
No. Off-grid systems aren't connected to the grid, so there is no export or net metering. Surplus charges the battery instead.No. Off-grid systems aren't connected to the grid, so there is no export or net metering. Surplus charges the battery instead.
Is off-grid cheaper because it has no grid charges?Is off-grid cheaper because it has no grid charges?
Usually not. Batteries make off-grid more expensive to build and maintain. The saving is not paying for grid supply at all, which matters most where the grid is absent or unreliable.Usually not.

What if I have an unreliable grid but want savings too?What if I have an unreliable grid but want savings too?
A hybrid system is usually the answer: it delivers bill savings through solar and net metering while providing battery backup during outages.A hybrid system is usually the answer: it delivers bill savings through solar and net metering while providing battery backup during outages.
