Homes in the Randwick council area
What we check on a home in the Randwick council area.
Every house is different, but homes in the Randwick council area raise the same few questions. We answer them on the site visit, before you see a price.
Salt air along the coast
Some battery and inverter makers reduce warranty cover close to the sea. We check your home's distance from the water against the maker's manual and put the battery where the warranty holds.
Older tiled roofs
A lot of the older brick houses here have terracotta or concrete tiles that crack underfoot. We check the roof on the site visit and tell you before we start if some need replacing.
Heritage conservation areas
Parts of Randwick sit in heritage conservation areas, where extra rules apply to panels seen from the street. We check your address before we design anything.
The battery rebate
The rebate, in plain English.
A battery charges from your solar during the day so the house runs on it at night, instead of buying that power from the grid. The federal Cheaper Home Batteries Program takes money off the price of the battery.
Straight off the price
$4,170* off an 18kWh battery, taken off your quote. SIPENERGY claims it as the accredited installer, so there's no form for you to fill in later.
It goes in with solar
The battery has to be installed with solar panels: the ones already on your roof, or new ones fitted at the same time.
Smaller from 1 January
From 1 January 2027 the same battery gets $3,490*. The install date decides the amount, not the date you sign.

How it works
One power bill. A straight answer.
01
Tell us your power bill
What you pay a quarter tells us roughly how much power the house uses, which is what decides whether a battery is worth it.

We tell you straight
Someone from our Sydney team calls back with whether a battery suits your home, what size, and what the rebate takes off. If it doesn't stack up, we say so.
03
Free site visit and quote
We come to your home and check the roof, the switchboard and where the battery can go. The rebate is on the quote, so you see the price you pay before you sign.

What SIPENERGY customers say
Frequently asked
Batteries in the Randwick council area, answered.
Do you install across the Randwick council area?
Yes. Homes from Kensington and Kingsford down to Little Bay have chosen us, and Maroubra has more SIPENERGY homes than any other suburb we work in. Put your address on the form and we'll confirm.
How much is the battery rebate?
$4,170* off an 18kWh battery installed with solar. It's the federal Cheaper Home Batteries Program and it comes straight off the price on your quote, so there's nothing to claim later. On 1 January 2027 it drops to $3,490* for the same battery, and the install date decides which amount you get.
Do I need solar panels already?
The battery has to be installed with solar. If you already have panels, we can usually add a battery to them. If you don't, we put panels and a battery in together, and the solar earns its own federal rebate too.
What's a kWh, and what size battery do I need?
A kWh (kilowatt-hour) is how much energy a battery holds. 10kWh suits a lot of family homes; households with evening air con, a pool or an electric car often go larger. Your power bill shows how much you use and when, which is why we ask for one before recommending a size.
Will a battery pay for itself?
It depends on your tariff, how much power you use in the evening, and whether you have solar already. A battery stores solar from the middle of the day so the house can run on it at night instead of buying from the grid. Savings vary from home to home, and we'll give you our honest read rather than a guaranteed number.
Will a battery keep the lights on in a blackout?
It can, if the system is set up for backup. Not every installation is, so tell us if that matters to you and we'll design for it.
Which batteries does SIPENERGY install?
Sigenergy is the brand we recommend first, followed by GoodWe and Sungrow, and we fit the Tesla Powerwall 3 on request.
Who does the install in the Randwick council area?
Our own licensed electricians, from Sydney. SIPENERGY was started by Nicholas Sipple, an electrician, and every install carries a 12-year workmanship warranty on top of the battery maker's own.
The small print
- 18kWh battery installed with solar by 31 Dec 2026, federal Cheaper Home Batteries Program. $3,490 from 1 Jan 2027. Depends on battery size and certificate prices. The rebate is a federal government program, not a SIPENERGY discount. It is applied at the point of sale by SIPENERGY as the accredited installer. Amounts depend on usable battery capacity, installation date and certificate prices, and the program pays a reduced rate on capacity above 14kWh. Indicative only. The 3,000+ figure counts solar and battery systems SIPENERGY has installed for homes and businesses.
- Savings vary with your tariff, your household usage and your system. Nothing on this page is a guarantee of a financial outcome. Your cooling-off rights under Australian Consumer Law are unaffected.
