6.6kW solar system FAQs
How much power does a 6.6kW solar system produce?
In Melbourne a north-facing 6.6kW system averages roughly 24kWh a day across the year – more in summer, less in winter. Orientation, tilt and shade change this, so your quote includes a system-specific estimate.
How much does a 6.6kW solar system cost?
The price depends on the panel and inverter brands, your roof type, number of storeys, switchboard and whether you need 3-phase. We quote upfront with rebates already deducted and every extra listed, so there are no hidden costs. See solar and battery prices in Melbourne.
Can I add a battery to a 6.6kW system later?
Yes. Choose a battery-ready hybrid inverter now and a battery can be added later without replacing your system. We can also add a battery to an existing system after checking inverter compatibility.
How long does installation take?
Installation is completed within 3 weeks of signing in Melbourne and within 4 weeks in regional Victoria. Most homes are installed in a single day.
