Solar for rentals calculator

The value of a solar system can be shared fairly between landlords and tenants in certain circumstances. This calculator can help landlords and tenants work out if solar is the right option for their rental.

Landlords can use the calculator to estimate a payback period and calculate a fair rent increase for their tenants, while tenants can use it to estimate their savings from solar for different system sizes and rent levels.

The Queensland Government’s Supercharged Solar for Renters program will provide eligible landlords with rebates of up to $3,500 to install solar systems on their rental properties. For landlords and tenants using the calculator, please note that rental adjustments entered may not reflect specific requirements under the rebate program. More information, including eligibility, will be released ahead of the program launch later in 2025.

How the results are calculated

For regional Queensland customers, and South East Queensland customers who do not enter specific general supply and feed-in-tariff rates, tenant benefits are based on the 2025-26 Tariff 11 and regional feed-in-tariff rates for Ergon Energy customers. The calculator assumes that each kilowatt of solar PV installed generates 4.2 kilowatt hours per day, that tenants self-consume 30% of the solar generated (for 3kW to 7kW systems), and 21% of the solar generated (for 10kW systems). Actual tenant benefits will vary depending on their individual usage of the system.

Disclaimer

The information in the calculator is provided by the Queensland Government as an information source only to assist landlords and their tenants in determining the financial, tax and other implications of installing solar on a rental property. The results do not address the particular circumstances of any individual and are best seen as illustrative examples under the stated assumptions.
