OK I have a power bill in hand and this month was 93.25 total. It was quite warm this month so this is a higher than average use month.
Looks like I used 662 kWh and the rate is 0.0906 for the first 450 kWh ($40.78), then it jumps to 0.137 for the last 212 kWh ($29.12). There are also fuel cost adjustment fees and taxes which brings up the rest.
Y'all can do your analysis as needed but I don't think this unit is causing me much pain electricity wise. The fan is on all the time, but the AC only kicks in very occasionally. If I sit outside the unit for an hour in the middle of the day, it'll kick in 2 or 3 times.
If I can wrangle the funds to do a PV system, this thing will be essentially free to run in the future. I'm sure my dad's house, which has a pool and a whole house AC unit uses way more juice as his bill used to be over 200 a month. He installed a 16 panel PV system last year and now his bill is only about 15 bucks a month.
