Stats updated: 2026-07-19
Yes, for most Australian homeowners, solar remains a highly worthwhile investment in 2026, with typical payback periods ranging from 3 to 6 years. Despite lower feed-in tariffs, the primary value now comes from self-consuming your generated electricity, saving 35-45c/kWh on your bill, which is significantly more valuable than exporting. A standard 6.6kW system can save around AUD $1,500 to $2,200 annually, providing substantial long-term financial benefits for over two decades after the initial investment is recouped.
In July 2026, the average installed cost for a quality 6.6kW solar system in Australia, after federal rebates, typically ranges from AUD $5,000 to $8,500. For larger residential systems, a 10kW setup generally costs between AUD $8,000 and $13,000 post-rebate. These prices reflect standard quality Tier 1 panels like Jinko or Trina, and reputable inverters such as Fronius or Sungrow, with premium systems costing 20-30% more.
The primary federal incentive is the Small-scale Technology Certificate (STC) scheme, which provides an upfront discount on your solar system, with the value for a 6.6kW system typically between AUD $1,550 and $2,100, varying by postcode and the current STC market price (around AUD $37-$40 per certificate). States like Victoria offer additional support, such as the Solar Homes Program providing up to AUD $1,400 for eligible households. Feed-in tariffs (FiTs) are credits for excess solar electricity exported to the grid, typically ranging from 2c to 12c/kWh, but their value has decreased, making self-consumption the most financially beneficial aspect of solar.
