Battery storage

Solar batteries for Fremantle and Perth homes

A battery stores daytime solar for later use, but capacity and payback depend on your exports, evening demand and tariff. We check those numbers before recommending one.

Based in Hamilton Hill, serving Fremantle and Perth metro

Why add a battery?

Many Perth homes export solar in the middle of the day and buy power back at night. A battery can shift some of that energy into the evening. Backup is separate: it only works when the battery and system are designed and configured for it.

We install batteries with new solar or assess add-ons to existing systems across Fremantle and the wider Perth metro from Hamilton Hill. Eligible homes may also access federal and WA battery incentives. See our solar and battery rebates page for an overview. Your quote shows the net price.

Tesla Powerwall and other options

Unisol is a Tesla Powerwall certified installer. We also compare other batteries where their capacity, output, warranty or compatibility is a better match for the property. Starting from scratch? See solar panel installation first.

FAQ

Battery questions

Is a home battery worth it in Perth?

It depends on your electricity use, solar generation, tariff and the installed price after incentives. We also consider what you want from a battery, including backup power, and future plans such as an electric vehicle or heat pump. We use those details to recommend a battery that suits your household and explain the likely benefits and costs.

Do you install Tesla Powerwall?

Yes. Unisol is a Tesla Powerwall certified installer. We can also discuss other batteries if they fit your home better.

Can I add a battery to existing solar later?

Often yes, depending on the inverter, switchboard, available space and the battery architecture. We check compatibility before specifying equipment and arrange a site visit when those details cannot be confirmed remotely.
