Solar + Battery Package Prices in NSW

 Here is the number most people are after: a solar and battery package in NSW costs roughly $11,000 to $20,000 fully installed in 2026, after the federal rebates. The most common pairing, 6.6kW of panels with a 10kWh battery, lands around $11,000 to $15,000 all in. Where you sit in that range depends on the battery brand, whether your home is single or three-phase, and how much electrical work your property needs before anything goes on the roof.

This guide sets out package prices by size, what the rebates knock off in NSW specifically, and why bundling solar and a battery together usually costs less than buying them a year apart.

Package prices at a glance

Fully installed NSW figures for 2026, after the federal STC discount on the solar and the federal battery rebate. These assume a single-visit install on a standard roof, so switchboard upgrades, two-storey access or long cable runs push the figure up.

Package	Suits	Typical installed price (2026, after federal rebates)
6.6kW solar + ~5kWh battery	Small households, modest evening use	$8,500 to $11,500
6.6kW solar + 10kWh battery	The popular choice for 3 to 4 people	$11,000 to $15,000
6.6kW solar + 13.5kWh (e.g. Powerwall 3)	Higher evening use, whole-home backup	$14,000 to $20,000
10kW solar + 13.5kWh battery	Larger homes, pools, EV charging	$16,000 to $22,000

Prices move through the year and vary by installer, so use these to sanity-check a quote rather than as a fixed rate. To size the solar half properly, our guides to 6.6kW system costs and returns and 8kW system output are a good start, and the battery half is covered in our 10kWh battery price guide.

What the rebates take off in NSW

Two federal rebates apply to a package, and NSW adds a couple of extra levers on top.

Federal STC discount on the solar. The Small-scale Renewable Energy Scheme discounts your panels upfront through certificates your installer sells on your behalf. For a 6.6kW system in NSW in 2026 that is worth roughly $1,500 to $2,000, and a 10kW system around $2,000 to $3,000. The catch is the step-down: the deeming period dropped from six years to five on 1 January 2026, trimming a few hundred dollars off the discount, and it shrinks again each January until the scheme ends in 2030. Our NSW solar rebates guide keeps the detail current.

Federal battery rebate on the storage. The Cheaper Home Batteries Program takes around 25 to 30 per cent off an eligible battery, applied upfront by your installer. In 2026 that is roughly $2,500 to $3,000 off a 10kWh battery and closer to $4,000 to $4,500 off a 13.5kWh Powerwall. Since 1 May 2026 it pays in tiers: the full rate on the first 14kWh of usable capacity, then a reduced rate above that. See our federal battery rebate guide for how it is calculated.

NSW VPP incentive. NSW does not run a direct cash rebate for batteries, but the Peak Demand Reduction Scheme can add up to around $1,500 off when your battery is enrolled in an approved virtual power plant. Our virtual power plant page explains the trade-offs before you sign up.

NSW Home Energy Saver loan. For households that would rather spread the cost, NSW offers interest-free loans of up to $15,000 for solar and battery systems, repayable over several years. We cover eligibility in our note on the Home Energy Saver program, and there are private finance paths on our finance options page.
