What are the current costs and rebates for solar panels and home batteries in Australia?

As of September 2026, a standard 6.6kW solar panel system typically costs between AUD $5,000 and $8,500 fully installed after the federal Small-scale Technology Certificates (STC) rebate, which can be around $1,400 to $2,115 depending on your STC zone (e.g., $1,780 in Sydney, NSW). For home battery storage, a common 10kWh system generally costs between AUD $7,000 and $11,000 after the federal Cheaper Home Batteries Program discount, which provides approximately AUD $250 to $300 per usable kWh for the first 14 kWh. State-specific battery incentives also exist, such as the NSW VPP incentive (up to $1,500 for joining a Virtual Power Plant) and WA's Residential Battery Scheme (up to $1,300 for Synergy customers or $3,800 for Horizon Power customers), which stack with the federal discount.

Should I invest in an Electric Vehicle (EV) or a home solar battery first for maximum savings?

The decision between an EV and a home solar battery depends on individual circumstances, but both offer significant savings. EV charging at home is considerably cheaper than petrol, costing around AUD $4–$8 per 100 km compared to AUD $18–$20 for petrol vehicles, with potential near-zero costs if charged directly by surplus rooftop solar. The federal Fringe Benefits Tax (FBT) exemption for eligible EVs (under $89,332 in 2026) can save employees AUD $5,000–$25,000+ through novated leases. While solar batteries offer energy independence and blackout protection, their payback period on the Australian east coast is typically 9-10 years for a 10-20 kWh battery at current prices. Many analysts suggest that optimising daytime electricity use (e.g., charging an EV during solar production hours) can yield immediate savings of AUD $200–$500 annually, potentially outperforming a standalone battery in the first decade.

How can Australians find the cheapest electricity plan and save on their energy bills in 2026?

Australian electricity prices vary significantly by state and network, with annual residential bills ranging from around AUD $1,591 in Victoria to over $2,600 in some parts of New South Wales. To find the cheapest plan, consumers in NSW, ACT, Queensland, South Australia, and Tasmania should use the Australian Government's free and independent Energy Made Easy comparison service. Victorian residents should use Victorian Energy Compare. It's crucial to compare usage charges (e.g., 33.6 c/kWh in Tasmania to 51.6 c/kWh in South Australia for standing offers), supply fees, and any conditional discounts, reviewing your contract annually. From July 1, 2026, the AER's Solar Sharer Offer in NSW, SA, and SE QLD mandates retailers to provide plans with three free hours of daytime electricity (11 am-2 pm in NSW/SE QLD, 12 pm-3 pm in SA), which can be leveraged for significant savings.
