How much power is used
Total electricity use creates the starting picture. Seasonal changes add useful context.
Solar savings conversations
Useful solar numbers start with your actual property—not a website calculator.
System size, usage timing, tariffs, export settings, shade and equipment scope can all change an outcome. The assumptions should be clear before anyone leans on a headline figure.
What changes the result
Four inputs worth understanding.
Every property is different. These are the kinds of inputs that should be visible when solar performance and household energy costs are discussed.
When power is used
Daytime, evening and overnight usage affect how much solar can be used directly at the property.
What the property allows
Roof space, orientation, shading, switchboard and equipment locations influence the system design.
Read the assumptions
A useful quote explains what sits behind the numbers.
The written proposal should make it easier to understand how the design was reached and what could change the outcome over time—without pretending one figure fits every Adelaide home.
- Current electricity use and timing
- Proposed system size and site constraints
- Tariff and export assumptions used in the discussion
- Solar-only, battery-ready or battery storage pathways where relevant
- Any future EV charging or large electrical loads
A better comparison
Compare the design, not just one figure.
Ask enough questions to understand why the proposed system fits the property and what assumptions the conversation relies on.
Is the usage profile realistic?
Recent bills and a clear picture of daytime and evening use make the starting point stronger.
Are the inclusions clear?
Look for the proposed equipment, electrical scope, site work and any stated assumptions.
What could change later?
Discuss tariff changes, household usage, battery storage and future EV charging plans.
Start with a property discussion
Put the property and your goals at the centre.
Adelaide SolarSafe can discuss solar, storage and future loads around the actual site. A bill or quote can help, but is not required; email or call.
