Top 10 Solar Panel Installers in New South Wales

Solar Choice's price index for 1 October 2026 puts the average Sydney price at $5,750 for a 6 kW system and $6,450 for 7 kW, after the STC discount and including GST. A 6.6 kW system usually falls between those. Premium systems averaged $6,750 to $7,640. Our NSW city guides find most quality 6.6 kW systems in a band of about $5,000 to $9,000 after STCs. Budget installs start around $4,000, and premium microinverter systems can reach about $13,000. Compare at least three itemised quotes.

As of October 2026 there is no NSW rebate for household solar panels, and the NSW home battery installation discount closed on 1 July 2025. The federal STC discount applies to panels. A 6.6 kW system in Sydney, which is in zone 3, earns about 45 certificates in 2026, worth up to about $1,800, falling to about 36 in 2027. Batteries get 6.8 certificates per usable kWh on the first 14 kWh until 31 December 2026. On top of that, the NSW VPP incentive pays an upfront amount when you sign a battery up with a participating provider.

NSW does not set a minimum feed-in tariff. IPART publishes a benchmark, 3.4c to 6.5c per kWh for 2026-27, and retailers do not have to match it. Standard retailer rates we checked in August 2026 were about 2.5c to 3c, with capped boost plans up to 8c. Networks set export limits. Endeavour Energy and Essential Energy commonly allow 5 kW per phase, and Ausgrid allows more in many areas, but limits vary by street. Networks can also apply two-way tariffs that charge for midday exports above a free threshold and pay a credit in the evening peak.

You get an upfront payment for connecting an eligible battery to a participating virtual power plant. The payment comes through the VPP provider, not directly from the government. It depends on the provider, your contract and the battery capacity you make available, up to 28 kWh. From 1 July 2026, batteries from 2 kWh up to 50 kWh can qualify, including those installed under the federal program. It can be claimed once per electricity meter. The NSW Government does not publish a fixed amount, so compare offers and check how much control over your battery you hand over.
