Wow your current electricity must be really expensive... or your solar setup is?? Also the calculation was done by the company selling it, I'm pretty sure that was far too optimistic.

That actually sounds pessimistic to me. My ROI for 18kW solar plus 42kWh battery will be under 3 years.

- Expensive electricity

- Government subsidy for solar and battery

- Much sunshine

- 3 hours free charging daily

Nearly $5000 yearly bill gone. $14000 installation cost post rebate.
