Baseline credit is a separate line item.

If baseline is 300 kWh and you use 400 kWh (net) and the credit is 10 cents you get a line item that says credit $30
The rest of the tiers are charged as used. You can net them in your head any way you like.

Yes, I agree. This was hard for me to get my head around as well. Once you exceed your baseline allocation in net usage, your SOP incremental rate goes to $.11/kWh, not $.01/kWh. That is still awfully cheap for California, although it is nothing special or even high for states burning coal.

TOU D-A worked reasonably well for me all last year, except Aug and September, where I just could not wait for 8pm to power up the A/C. However, on less extreme days I broke even on OnPk, generating as much after 2pm before sundown as I consumed with A/C after dark before 8 pm. On weekends I accumulated net credits for OffPk in the afternoon to use during the week.
Prior to 2015 TOU DT-EV with its 10am to 6pm OnPk window was much more generous for me.

Even at $.11/kWh, charging the Tesla after full day excursions really broke the bank for me last year, so I am hoping to install a few more solar panels. The good roof is all gone, but I have some eastern exposure that is will generate about 4 hours per day, 9am to 1pm. In the winter, the angles are shallow, but in summer I will get decent Offpk production in the morning.

Last September, in the middle of the heat wave, I also installed a 3 kW ductless mini-split Mitsubishi inverter heat pump system for the 3 rooms I use the most. I expect it will save me a lot next summer. Right now I am running the heat pump in reverse to reduce my natural gas usage (a la Porter Ranch), but getting serious with this will have to wait until I get the extra solar.

I added 6 - Solar World 245's, last year. Turned out to be overkill. I ended the year with a $150 credit, after running two portable electric heaters 7/24 for November and December, used 1200+ kWh for December. I true-up 12/31 and went positive for the year on 2/12. Should have a $30 credit at the end of the month.

I have $350 credit after 9 months with a 9kW system, and I'm a net consumer so far. Probably could have gone with a smaller array but considering SCE tends to change rate schedules to screw solar customers every so often and reduced solar output over time I'm likely in a good shape for long term.

You can avoid A/C during OP?

Yes mostly. I have two air conditioners. I run the downstairs at 62 overnight on hottest days. Creeps up to 78 or 80 inside by 8pm. Upstairs I don't cool as much overnight and is set to 88 during the day until 8 pm goes to 78. 10 pm to 74 and maybe 68 to sleep. On hottest days the compressors will run about continuous from 12 am to 6 am. Dishwasher run every night at 12 am. Laundry and electric oven on weekends only. Xmas lights are mostly LED.

The temperature swing in the house actually mimics a natural cycle so we have gotten used to it. Easier to make it to 8 pm when you know the air will kick on a bit and continue to cool through the night. Or just find something else to do and keep your mind off the heat.

Interesting - I wonder how much energy this uses compared to say keeping the house at a steady 76-78 perhaps cooling off to 70 at midnight?

For extracting a fixed BTU I do believe the cooler overnight temperature helps efficiency vs some cycling mid day at 95+.
It is well known high temperatures cause higher starting and running current for the compressor.

Yes, I agree. Keeping the thermostat set at any one "steady" temperature does not increase efficiency by itself. There is a cost to frequently starting and stopping a conventional A/C without inverter motor technology, but raw A/C efficiency decreases when the difference between outside and inside temperatures increases. If you can stand to run the A/C less during the hottest part of the day, and then run it more after the outside has started to cool off, you will gain in efficiency.
