Frequently Asked Questions
What should I install first — solar or battery?
Solar first, always. Solar has a 3-6 year payback vs 8-12 for batteries. Install solar, live with it for a few months to understand your usage patterns, then decide if a battery makes sense for your situation.
How much can I save by going all-electric?
A typical dual-fuel home in Victoria can save $1,500-$3,000 per year by going all-electric (including eliminating the gas supply charge). The exact savings depend on your current gas usage and the cost of replacement appliances.
What's the total cost to electrify my home?
Full electrification typically costs $15,000-$30,000 before rebates: solar ($5-8k), battery ($8-15k), heat pump hot water ($3-4k), induction cooktop ($1.5k), and reverse cycle heating ($2.5-10k). After rebates, the net cost drops significantly.
Is it worth disconnecting from gas?
If you can replace all gas appliances, yes. The gas daily supply charge alone ($300-365/year) is a compelling reason. Combined with the efficiency gains of heat pumps and induction, most homes save $800-2,000/year after switching — paying off the upgrade cost in 5-8 years.
