From roof space to return on investment.
A live first-pass model based on the bill, roof and load profile above. It is deliberately sized for self-consumption—not simply to fill the roof.
Approximately 63% of the entered annual bill.
Calculation assumptions and important limitations
The model assumes 1,300 kWh/kW annual generation, A$0.26/kWh usage tariff, A$0.05/kWh export value, an indicative installed cost of A$1,360/kW and an indicative current-scheme support for systems below 100 kW. For recommendations of 100 kW or more, it applies an announced-policy scenario of about 20%; that expansion is not yet guaranteed and remains subject to regulations and eligibility. Actual results depend on interval data, demand charges, roof condition, shading, network approval, design, finance, tax and final scheme regulations.
Solar works hardest where the business works in daylight.

Separate today's rules from tomorrow's announcement.
Under the current Small-scale Renewable Energy Scheme, eligible solar PV systems up to 100 kW may create Small-scale Technology Certificates, subject to the scheme's equipment, design, installation and other requirements.
On 5 August 2026, the Australian Government announced an intended expansion of the upfront solar discount to systems below 1 MW, with an estimated reduction of around 20% for eligible projects. The expansion remains subject to regulations, final rules and project eligibility. Calculator outputs are scenarios—not a guarantee of a rebate, certificate value or savings.
