System Type
Hybrid
We chose a hybrid system, expecting a slightly lower return than panels only, but wanting resilience from power cuts.
The inverter is only 5kW, so it can’t convert the last bits of the panels’ electricity to AC power at midday in summer. But we don’t need the power then, and it’s efficient in winter.
Battery Capacity
7.3 kWh (6.5 usable)
7.3 kWh (6.5 usable)
Cost
$22,000 installed
The quote was for $22,000 installed. A meter change to support exporting power to the grid was a further $160. There were no additional fees from the installer.
Savings
estimated $2,400 p.a
The installer correctly estimated the electricity that would be generated on a monthly basis. So far, we have 1% difference between actual and estimated. We generate about 9,000 kWh a year.
Installer

Solar Worx – We would use them again.
