10 year ROI is what I got quoted on a solar setup. I live in Queensland. It’s very sunny here.
- brabel 2mo agoWow 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.
- jazoom 2mo agoThat 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.
- brabel 2mo agoWith a calculation like that I'd buy solar in a heart beat! But as I said, my main concern is my winter bill, which I know by asking people who own solar in the region, is almost the same with solar since there's no sun at all (it's not that it's cloudy, it's that the entire day duration is like 4 hours - under which you barely feel any sun heat and in practice the solar output is exactly zero on the worst month and near zero for 4 or so months). Hence the very long ROI here, but I agree that for Queensland, 10 years would be a bit too long if you dimension the solar array properly.
