Frequently Asked Questions

A home battery stores excess electricity generated by your solar panels during the day, allowing you to use that energy later in the evening or overnight when your panels are not producing power.

A battery can be installed on its own, but it delivers far more value when it is charged by your own rooftop solar rather than from the grid. In most homes a battery is paired with solar for that reason.

Often, yes. A battery can usually be retrofitted to an existing system, though compatibility depends on your inverter, system age and design. We assess your setup and advise honestly on the best option.

Most quality home batteries are designed to last around 10 to 15 years and come with a manufacturer warranty covering a set number of cycles or years of use.

The right size depends on your daily energy use, how much solar you generate and how much of the evening peak you want to cover. We size each system to the household rather than selling a one-size-fits-all product.

Yes. By storing and using more of your own solar energy, you can reduce the amount of electricity you purchase from the grid, especially during expensive evening peak periods.

Storage capacity varies by product, typically ranging from around 5kWh to well over 15kWh. The right capacity depends on your usage and how much of your daily energy you want to cover.

For many households, yes, particularly where evening electricity use is high and grid prices keep rising. The payback depends on your usage, system size and any available incentives, which we help you weigh up.

Significantly. Without a battery, excess solar is often exported to the grid for a small feed-in tariff. A battery lets you store that energy and use it yourself, getting far more value from every panel.

Payback periods vary with your energy use, system size and electricity prices, but many households see a return over the medium term. We give you honest, realistic numbers rather than best-case estimates.

Most residential battery installations can be completed within a day, although larger or more complex systems may require additional time.

Many battery systems offer backup functionality that keeps essential circuits running during an outage. Not all systems include this by default, so we confirm your backup needs during the design stage.

Home batteries are largely maintenance-free. We recommend occasional monitoring through the system app and a periodic check as part of servicing to keep everything performing at its best.

Yes. Most systems include a monitoring app that shows your solar generation, battery charge and household usage in real time, so you always know how your system is performing.

The best way is a free consultation. We assess your energy use, existing solar and goals, then give you an honest recommendation on whether a battery makes sense for you now or later.
