Clean Energy Regulator postcode data to August 2026, against houses and townhouses at the 2021 Census (Australian Bureau of Statistics). Systems include upgrades, so read it as how common solar is, not an exact share of homes.

Shire batteries got smaller after the rebate changed

From 1 May 2026 the federal battery discount pays less for every kilowatt-hour above 14 kWh. Shire households noticed: the average battery dropped by 5 kWh.

Size a battery to what you use after dark, not to the rebate. A 13.5 kWh battery still earns the full rate on every kilowatt-hour.

The rate drops again on 1 January 2027

The rebate is fixed on the day the battery goes in. From 1 January the same battery earns about 16% less.

What Shire roofs need

Solar panels with stainless steel mounting rails on a metal roof near the water in southern Sydney

Salt air on the water

Cronulla, Kurnell, Sylvania Waters and Bundeena get salt spray. We use Schletter rails and stainless fixings rated for coastal sites.

Gums over the roof

In Engadine, Heathcote and Jannali, shade moves across the roof. Enphase microinverters stop one shaded panel pulling down the rest.

Bigger homes, bigger bills

Menai, Illawong and Barden Ridge are almost all detached houses. With a pool or ducted air, a 10 kW system and a battery usually pay their way.

Units and townhouses

In Cronulla, Miranda or Sutherland, solar on a unit depends on the strata. Ask us before the meeting and we will tell you what is practical.

Rebates for Shire homes

We claim them for you and take them off the invoice.

Solar panels (STC)

About $1,700 off a 6.6 kW system in 2026, under the federal Small-scale Renewable Energy Scheme.

Home batteries

About $252 per kWh for the first 14 kWh, less above that. Steps down again on 1 January 2027.

NSW VPP incentive

An extra payment if you join a virtual power plant. Optional, and not right for everyone.

Solar in the Sutherland Shire: Frequently Asked Questions

Do you install solar across the whole Sutherland Shire?

Yes. We are local solar installers for Sutherland Shire homeowners across the Shire, in every suburb, from Menai, Illawong and Engadine in the west to Cronulla, Kurnell and Bundeena in the east. We work Monday to Friday from our base in Peakhurst.

About 24,700 solar systems are registered in the Shire’s postcodes, roughly 40 for every 100 houses. Menai and Illawong (2234) have the highest rate, above 50.

New systems in the last 12 months averaged 11.2 kW. Most family homes land between 6.6 and 10 kW; the right system size depends on your electricity bill, not your roof area.

For most homes with solar and high evening use, yes. A battery stores excess solar energy from the day for the evening. Around 4,600 Shire homes added a battery between July 2025 and August 2026. Since 1 May 2026 the rebate pays less above 14 kWh, so size the battery to your evening use.

Yes. We use Schletter rails with stainless fixings and choose equipment rated for coastal sites. Salt spray is a reason to choose parts carefully, not a reason to skip solar.

Sometimes. It depends on the strata and the roof. Send us your building details and we will tell you whether it is practical before you go to the strata committee.

We do not publish package prices, because the cost of solar panels depends on your roof, the system size, your switchboard and how much power you use. You get one firm price after a free site assessment, with the STC rebate already off: about $1,700 on a 6.6 kW solar system in 2026.

Check three things: that the designer and installer hold Solar Accreditation Australia (SAA) accreditation, that the electrical contractor licence is current, and that the workmanship warranty is in writing. Ours are licence 202500C and up to 10 years, and every solar installation is done by our own crew, not subcontractors.

Often, yes. Batteries like Tesla Powerwall 3 and Sigenergy SigenStor have their own built-in inverter, so they can work alongside an older solar inverter. We test your existing system first and tell you whether a battery installation makes sense.

On most homes, no. Rooftop solar is exempt development under the NSW Transport and Infrastructure SEPP 2021. If your home is a heritage item or sits in a heritage conservation area, panels on the roof facing the street need sign-off from Sutherland Shire Council first. We check this before we quote.
