Home batteries

Stop selling your solar for cents and buying it back for dollars

Most solar homes export their midday surplus for a few cents a kWh, then pay full price for power from about 4pm, when the household is home and peak rates kick in. A battery keeps that surplus and uses it when it's worth the most.

Morning – 3pm

Panels power the house. Spare solar charges the battery.

4pm – 9pm

The battery covers the evening peak instead of the grid.

Overnight

What's left runs the fridge and standby loads till sunrise.

The federal battery discount

  • The Cheaper Home Batteries Program cuts the upfront cost of eligible home and small-business batteries through small-scale technology certificates (STCs). It requires installation by an SAA-accredited installer.
  • Since 1 May 2026 the discount tapers with battery size, and the STC factor steps down every six months, so it shrinks over time.
  • In NSW, connecting your battery to a virtual power plant (VPP) may earn an additional NSW Government incentive.

How we worked this out
  • Sydney solar yield of about 3.9 kWh per kW of panels per day, averaged over a year.
  • Your bill is converted to usage at about 33c/kWh after a daily supply charge of about $1.10.
  • Panels are sized to generate about 125% of your average daily usage, then rounded up to a common system size (6.6, 8, 10, 13.2, 15 or 20 kW; minimum 6.6 kW). Systems above about 10 kW usually need three-phase power and network approval.
  • Batteries are sized at about half your daily usage, rounded up to a common size (10, 13.5, 16, 20 or 27 kWh usable; minimum 10 kWh).
  • Solar you use yourself saves the full rate; exported solar earns about 5c/kWh. Without a battery about 35% of solar is used at home, with one about 75%, capped at 90% of your usage.
  • Savings shown as a ±20% range. Excludes system price, the battery discount and tariff changes.

FAQ

Questions we get asked a lot

Can't see yours? Call us on 0455 475 382. You'll get a straight answer.

How much will solar and a battery cost?

It depends on your usage, roof, switchboard and the equipment you choose. We'll give you a fixed, itemised written quote with any eligible STCs and battery discount already deducted. No surprises.

Is a battery worth it for my home?

Batteries usually suit homes that use a lot of power in the evening, or that export lots of solar for a low feed-in tariff. If yours isn't one of them yet, we'll tell you straight.

Can I add a battery to my existing solar system?

Often, yes. We check your existing inverter, panels and switchboard and recommend either an AC-coupled battery or an inverter upgrade.

What's a PPA and is my business eligible?

A solar power purchase agreement lets a business host a solar system it doesn't pay for upfront. We own and maintain it, and you buy the electricity it produces at an agreed per-kWh rate. PPAs usually suit businesses with steady daytime usage, suitable roof space and a long-term lease or ownership of the site.

How long does installation take?

It depends on the size of the system, your switchboard and network approvals. We'll give you an expected timeline with your quote, and ask us any time about scheduling.

What warranties do I get?

Manufacturer product and performance warranties on panels, inverters and batteries, plus your rights under Australian Consumer Law.
