Solar and Battery Rebates and Incentives: What Applies to You in 2026

As of August 2026, NSW households can combine three incentives on a solar-and-battery install: Small-scale Technology Certificates (STCs) on new solar, the Federal Cheaper Home Batteries Program (roughly 30% off installed battery cost), and the NSW PDRS battery incentive (~$1,100–$1,500 upfront). The federal and NSW battery incentives stack on the same installation, and several step down on a set schedule — so acting earlier generally means a larger discount.

Updated August 2026 for NSW residents. The figures on this page are current as of August 2026. Solar and battery incentives step down on set schedules — always confirm current values against the official government sources linked below before signing a contract.

Quick answer (TL;DR)

• STCs discount new solar at point of sale (~$2,000–$2,500 off a typical 6.6kW system); step down each 1 January.
• Federal Cheaper Home Batteries Program discounts ~30% of installed battery cost via STCs; steps down ~every 6 months to 2030.
• NSW PDRS adds ~$1,100–$1,500 upfront on eligible batteries and stacks on top of the federal rebate.
• From 1 July 2026 the NSW battery incentive no longer requires existing solar.
• From 1 September 2026 businesses and strata become eligible.

What is the Federal Cheaper Home Batteries Program?

The Federal Government's Cheaper Home Batteries Program discounts the installed cost of a home battery by roughly 30%, delivered via Small-scale Technology Certificates (STCs). The discount is tiered by battery capacity:

• Approximately $272 per kWh for the first 14kWh of battery capacity
• Approximately $163 per kWh for capacity between 14kWh and 28kWh
• Approximately $41 per kWh for capacity between 28kWh and 50kWh

The scheme is legislated to run through to 2030, with the per-kWh value stepping down roughly every six months as the program progresses. A battery installed today generally attracts a larger discount than the same battery installed a year or two from now. For most typical residential battery sizes (10–13.5kWh), this discount represents a meaningful share of the total installed cost.

What is the NSW PDRS battery incentive?

On top of the federal discount, the NSW Government's Peak Demand Reduction Scheme (PDRS) provides an additional upfront incentive of approximately $1,100 to $1,500 for eligible home battery installations, and this stacks directly with the federal Cheaper Home Batteries Program rather than replacing it. Two important eligibility changes:

• From 1 July 2026, the NSW PDRS battery incentive no longer requires you to already have solar installed — meaning battery-only installations become eligible.
• From 1 September 2026, businesses and strata-titled properties become eligible for the first time.

What are STCs for new solar systems?

Small-scale Technology Certificates aren't new — they've underpinned the affordability of Australian rooftop solar for over a decade — but they remain the single biggest point-of-sale discount most homeowners receive. For a typical 6.6kW Sydney installation, STCs currently deliver an upfront discount of roughly $2,000 to $2,500 off the total installed cost, applied directly at point of sale so you never have to claim it back yourself. The STC value steps down each 1 January (see the Clean Energy Regulator). We handle the certificate creation and assignment as part of every installation.

How do these incentives work together?

For a household installing solar and a battery at the same time, these schemes stack:

• STCs discount the solar portion of the installation, applied at point of sale
• The Federal Cheaper Home Batteries Program discounts the battery portion via its own STC-based mechanism, tiered by capacity
• NSW PDRS adds a further fixed upfront amount on the battery, on top of the federal discount

The net effect is that the all-in cost of a combined solar-plus-battery system in 2026 is significantly lower than the same system would have cost even two or three years ago.

Why does the timing detail matter?

Because both the federal battery scheme and STCs step down on fixed schedules (roughly every six months and every 1 January respectively), the exact month you install can genuinely change your final price by a non-trivial amount. We factor current rates into every quote automatically, and flag clearly if a step-down is approaching that might be worth planning around.

Am I eligible?

Eligibility requires the battery to be on the Clean Energy Council approved products list and the installer to be CEC-accredited (Blue Energy Solar is). Every household and business is eligible for different combinations depending on system size, battery capacity, existing solar, location and timing.

Frequently Asked Questions

Can I claim both the federal and NSW battery rebates?

Yes. The NSW PDRS battery incentive stacks on top of the Federal Cheaper Home Batteries Program on the same installation. Confirmed as current as of August 2026 — verify on the official government pages before signing.

Do I need existing solar to claim the NSW battery incentive?

Not from 1 July 2026 — battery-only installations became eligible from that date. Before then, existing solar was required.

When do businesses become eligible for the NSW battery incentive?

From 1 September 2026, businesses and strata-titled properties become eligible for the NSW PDRS battery incentive for the first time.

How much is the STC rebate on a 6.6kW solar system?

Roughly $2,000–$2,500 off the installed cost as of August 2026, applied at point of sale. The value steps down each 1 January.
