Solar in Canberra
Canberra's clear inland skies deliver solid sun hours, and the ACT's Sustainable Household Scheme is one of Australia's best solar financing programs — offering 0% interest loans up to $15,000 repaid over 10 years via your electricity bill. The ACT government's ambitious 100% renewable electricity target makes it a particularly forward-thinking market for solar and battery investment.
💡 Local Tip
The ACT Sustainable Household Scheme loans cover solar panels, batteries, EV chargers, and other energy upgrades. At 0% interest over 10 years, the repayments are typically less than the electricity savings from day one — making it cash-flow positive immediately.
With an average system cost of $4,000–$6,200 for a 6.6kW installation after federal rebates, Canberra homeowners typically recoup their investment within 3–5 years. For a detailed breakdown of pricing factors, see our national solar cost guide. To understand all the rebates available in ACT, read our ACT rebate guide.

Adding a home battery to your Canberra solar system increases self-consumption from ~35% to ~70%, reducing your reliance on grid electricity during expensive evening hours. At current ACT feed-in rates of 6.0c/kWh, storing excess solar for evening use saves significantly more than exporting it. See our battery guide for costs and payback analysis. Your inverter choice also matters — read our inverter guide to understand your options.

ANNUAL RETURN
With electricity prices rising 4–6% annually across ACT, these savings increase every year. A $6,000 solar panel installation in Canberra that saves $1,800/year represents a 30%+ annual return — comfortably outperforming term deposits, shares, and most investment properties. Plus, solar panels add 3–4% to your property value according to Australian research, making it a strong financial decision even if you plan to sell.
Canberra Feed-in Tariffs
The current feed-in tariff in ACT is approximately 6.0c/kWh for excess solar exported to the grid. This rate is applied to any surplus electricity your panels generate beyond what your home uses in real-time.
At current rates, a 6.6kW system in Canberra exporting around 60–70% of generation would earn approximately $423/year in feed-in credits. The real savings come from self-consumption — every kWh you use directly saves 27c versus the 6.0c you'd earn exporting it.
