| Usage | kWh per Day | Cost per Day @ $0.15 | Cost per Month @ $0.15 | Cost per Month @ $0.30 |
|---|---|---|---|---|
| 2 hrs/day | 0.150 kWh | $0.022 | $0.67 | $1.35 |
| 4 hrs/day | 0.300 kWh | $0.045 | $1.35 | $2.70 |
| 8 hrs/day | 0.600 kWh | $0.090 | $2.70 | $5.40 |
| 24 hrs/day @ 50% | 1.800 kWh | $0.270 | $8.10 | $16.20 |
At California $0.45/kWh, 8 hours a day costs $8.10 per month.
