During the day
Panels power the home first. Surplus generation can charge the battery, subject to system settings and capacity.
Battery storage
Store energy. Use it when you need it.
Compare battery storage for off-peak charging, your existing solar panels, or expanding your current system. Choose battery quantity and a compatible inverter.

▣ Battery storage for later
How storage helps
Use more of your solar power after sunset.
Panels often generate more than a home uses in the middle of the day. A battery stores some of that excess for later use.
Later on
Stored energy can help cover evening or overnight use instead of buying all of it from the grid.
When there is surplus
Electricity that cannot be used or stored may be exported, subject to your system and export arrangements.
Choosing a capacity
How much battery storage do you need?
More storage is not automatically better value. Our quote tool compares compatible batteries and inverters, including installed price and estimated annual benefit. Open the savings details to see the assumptions behind the numbers.
Compare systems ↗Common questions
Battery basics.
Can a battery charge from the grid?
Some systems can be configured to charge on a lower-cost electricity tariff. The value depends on the tariff, battery settings and household use. The quote shows its configured assumptions.
Does every battery keep the lights on in a power cut?
No. Backup power requires compatible hardware and a suitable installation design. Ask about this during the survey if it matters to you.
How do you choose battery capacity?
We compare available system configurations with the roof layout and estimated use. A survey confirms the final choice and installation details.
