If you can only do one upgrade now, which wins — solar or a battery? Here is a simple way to decide based on how (and when) your household uses power.
The general rule: solar first, then battery
For most homes without solar, panels are the better first step. Solar reduces the power you buy from the grid during the day immediately, and typically pays back faster than a battery on its own.
A battery shines once you already generate solar and want to use more of it after the sun goes down.
When a battery makes sense sooner
Consider a battery earlier (or at the same time as solar) if you:
- Use a lot of power in the evening when solar isn't generating
- Experience regular blackouts and want backup
- Want to maximise independence from the grid
- Are on a tariff with expensive peak evening rates
Plan for a battery-ready system
Even if you start with solar only, ask for a battery-ready design. This makes adding storage later simpler and cheaper, and avoids reworking your system down the track.
A quick way to decide
| Your situation | Best first step | | --- | --- | | No solar yet | Solar (battery-ready) | | Have solar, high evening use | Battery | | Frequent outages | Solar + battery |

Frequently asked questions
Should I get solar or a battery first?
If you do not yet have solar, panels are usually the better first step because they cut your daytime grid usage immediately and pay back faster. Add a battery once you want to use more of your solar in the evenings.
What does "battery-ready" mean?
A battery-ready solar system is designed so a battery can be added later with minimal extra work — saving you money and hassle when you decide to add storage.
