Solar PV systems
Which solar system is right for you?
Every rooftop system uses the same basic parts. What changes is whether it keeps a battery, and whether it can send surplus power back to the grid.

Four questions
If not, on-grid gives the lowest cost and fastest payback. If yes, look at a hybrid system.
A modular hybrid system can reuse them, joined to solar by Powergate’s AutoSwitch.
An off-grid system works as a solar UPS and does not depend on the grid.
An integrated hybrid system combines net metering and battery backup in one inverter.
Side by side
| Feature | On-grid | Off-grid | Integrated hybrid | Modular hybrid |
|---|---|---|---|---|
| Needs the grid to run | Yes | No | No | No |
| Batteries | No | Yes | Yes | Yes |
| Power during a power cut | No | Yes | Yes | Yes |
| Exports surplus (net metering) | Yes | No | Yes | Yes |
| Works with an existing UPS | No | No | No | Yes |
| Relative cost | Lowest | Higher | Higher | Medium |
| Best for | Homes and businesses with reliable grid supply that want the fastest payback. | Farmhouses, remote sites and buildings where the grid is unreliable or unavailable. | New homes and buildings that want lower bills and backup in one neat system. | Homes and offices that already own a UPS and want solar without replacing it. |
