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 provides 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, can be found on the program website.

How the results are calculated
For South East Queensland customers who do not enter specific general supply and feed-in-tariff rates, tenant benefits are based on the estimated average of these rates (using a general supply tariff of 32.000 cents/kilowatt hour (kWh) and a feed-in-tariff of 4.000 cents/kWh).
For regional Queensland customers, tenant benefits are based on the 2025–26 Tariff 11 (32.973 cents/kWh) and regional feed-in-tariff (8.66 cents/kWh) 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.

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.
