AUSTRALIA · SOLAR & BATTERIES
Understand the household-energy questions behind solar and battery decisions in Australia, from electricity use and self-consumption to tariffs and storage.
What to understand first
Start with the household load
Solar and battery outcomes depend heavily on when and how much electricity a household uses. Annual consumption alone does not describe the timing of demand, which can affect how much solar generation is used directly or stored.
Tariffs affect the value of energy flows
The value of using, exporting or storing electricity depends on the applicable retail plan and export arrangements. Any comparison should state the tariff assumptions rather than treating them as universal.
Avoid guaranteed savings claims
System size, weather, shading, household behaviour, equipment performance and tariff changes can all affect financial outcomes. HomeBillLab will present scenarios and assumptions rather than guaranteed savings.

How HomeBillLab approaches this topic
We separate the numbers you can calculate from the assumptions that can change the result. Where a tariff, product label, official program or property-specific detail gives a better input, we prefer that information over a hidden national-average assumption.
