We stack federal STCs with VIC and NSW schemes — including NSW PDRS Peak Reduction Certificates on business batteries from 1 September 2026.
Get a quoteNSW
Up to $15,000 interest-free for eligible whole-home energy upgrades, with Energy Savings Certificates where they apply.
VIC
Solar Victoria rebate and interest-free loan options for eligible households, plus Victorian Energy Upgrades for heat pumps and efficiency.
Federal
Every eligible solar and battery installation generates STCs that reduce the upfront price. We assign certificates as part of the quote so the discount is clear from day one.
NSW
From 1 September 2026, NSW farms and businesses can create Peak Reduction Certificates on behind-the-meter batteries. Stack them on federal STCs to cut the cash you put in and lift ROI.
NSW commercial · from 1 September
From 1 September 2026, eligible NSW farms, sheds and commercial sites create Peak Reduction Certificates on a new behind-the-meter battery. Those PRCs sit on top of federal STCs on the solar — and on some smaller systems, on battery STCs / Cheaper Home Batteries too. That is how you cut the cash in and lift ROI, not by waiting for a better brochure.
BESS4
More than 20 kWh up to 200 kWh usable
Workshops, retail, sheds and many farms on the NSW side of our run.
BESS5
More than 200 kWh up to 30 MWh usable
Larger pumps, cold rooms, light industrial and community batteries. Certificates calculated on the first 10 MWh.
BESS3
More than 20 kWh up to 200 kWh usable
BCA Class 2 buildings with four or more dwellings.
PRCs are market-traded certificates, not a fixed government cheque. Value moves with the certificate price, usable capacity (typically 90% of nominal), inverter size, network loss factor and whether new solar is paired. Installations must be on or after 1 September 2026. Site cannot have already claimed BESS4 or BESS5. Planning approval, SAA-accredited install and listed equipment apply. We model the stack on a free site visit — we will not print a frozen dollar figure that is wrong by the time we turn up.

Rooftop solar
Federal STCs · NSW interest-free loan (if eligible)
Home battery
Federal STCs (where eligible) · NSW interest-free loan · PDRS PRCs if the site is a business battery (BESS4 / BESS5 from 1 Sept)
Farm / business battery (NSW)
PDRS Peak Reduction Certificates — BESS4 (20–200 kWh) or BESS5 (200 kWh–30 MWh) · Federal STCs on eligible solar · Cheaper Home Batteries / battery STCs on some BESS4 systems ≤100 kWh
NSW farms, sheds and commercial sites can create Peak Reduction Certificates on a new behind-the-meter battery. BESS4 covers 20–200 kWh usable; BESS5 covers 200 kWh–30 MWh. Stack PRCs on federal STCs (and Cheaper Home Batteries on some systems ≤100 kWh) so the incentive actually shows up in the price.
Eligible NSW households can finance solar, batteries and other upgrades interest-free over a long term. Combined with STCs, some single-phase packages can be structured at $0 upfront when approved.
Victorian homes can structure $0 at install through third-party finance you apply for. It is not a rebate, not free, and not the NSW government loan — repayments and approval sit with the lender. We help with the paperwork and still stack STCs and Solar Victoria where you qualify.
Victorian homeowners may access an upfront solar rebate and a matching interest-free loan — effectively pulling thousands off the install price when eligibility is met.
Victoria’s VEU program can take thousands off a heat pump hot water system. Combined with the Solar Victoria heat pump offer, many households see a mid-hundreds to low-thousands installed cost.
Solar Victoria’s induction cooktop rebate helps Victorian households leave gas cooking. We handle the electrical upgrade as part of the package.
