| You'd spend $1000 to save $0.20 on electricity every day? |

| The average price of power in Australia is 34 cents per kWh. The average Aussie spends A LOT more than $0.20 per day. |

| ▲ | testing22321 3 days ago | parent | next [-] | | The whole reason to spend the money on the battery is so you can use the free power for a lot longer than an hour or two! | |

| 7.3% return, not bad. As battery prices drop it will get even better. |
| |
| ▲ | marcosdumay 3 days ago | parent [-] | | It's not 7.3% return rate. There's some depreciation you need to add there. | | |
| ▲ | WheatMillington 3 days ago | parent [-] | | If you're going to depreciate the battery then your return will be substantially greater than 7.3%. You can't use BOTH the capex AND the depreciation as your denominator, choose one. |

| Where I live, $1000 would get you about 3kWh of battery power, which would pay for itself in a couple years |
