Hi, has anyone with solar, powerwalls and ev chosen TOU-D-4-9PM instead of the TOU-D-PRIME rate? I have solar (10kW), powerwalls (2x) and ev (low miles, not everyday) and think that more money can be made or saved with TOU-D-4-9PM than TOU-D-PRIME, even with its outrageous onpeak "all the time" during winter months.
With TOU-D-4-9PM you get a baseline credit every month, for me it appears to be around 350kWh at 0.07c, which is $24.5 per month for winter months. Daily charge is only 0.03c, and if you dont pull any power for that day an extra 0.35c daily charge.
With TOU-D-PRIME you have a 0.4c daily charge.
I went over the numbers and for me I think TOU-D-4-9PM might earn $1k vs TOU-D-PRIME earning $500. The numbers earned are most likely incorrect, but bottom line is that 4-9 is more advantageous than PRIME. Has anyone looked into this indepth? Are there extra charges they are not telling me about? I can share my calculations more if anyone is interested.
