Quick answer
The Australian Government lists typical Adelaide solar generation at about 4.2 kWh per installed kW per day averaged over a year.
What matters most
- South Australian homes can have strong rooftop generation and midday exports.
- Compare tariff structures, including newer time-sensitive plans.
- Model batteries using the avoided import rate minus lost export value.
Solar decision framework
Separate production from value. System size and location drive generation; your daytime load drives self-consumption; tariff structure determines what each kilowatt-hour is worth.
How to calculate it with SunnyWatly
Use the relevant calculator with your own bill, quote or vehicle information. Defaults are examples only and can become stale as tariffs, rebates and hardware change.
Do not rely on a headline figure alone. Ask what assumptions sit behind the estimate and whether they match your property, tariff and usage pattern.
What can change the result
- Electricity usage and time of day.
- Retail import and feed-in tariffs.
- Roof, shading, inverter or charger constraints.
- Hardware efficiency and usable capacity.
- Network limits and future tariff changes.
