SCE TOU-D-A Plan question

[Stuntman]

I just got my system turned on 8/1/2015.. very excited to be generating electricity.. From what I understand I am still on the Domestic rate schedule from Southern California Edison (SCE). I'm considering going to one of the Time of Use plans.. particularly option 'A'.. but as we are heading into shorter days with increased cloud cover (hello El Nino?).. should I go ahead and change my schedule now, knowing my production will shrink even as my usage remains the same? OR.. does billing START on the date I got my Permission to Operate, and I'll settle up that bill in one year from that start date, rather than a fixed calendar date such as January 1st?

If it is a year from turn on, then I guess it doesn't matter when I switch rate schedules?

Any advice from somebody who went through this already and can help me pull the trigger on that? I use a lot of power.. a family of 4, with a pool.. and in a home that is All-Electric, as propane/natural gas was never run to our neighborhood... I seem to be using about 1,700 kWh a month (will go down once pool needs less filtering).. my system is a 11kW system, though I'll likely never get to that number..

Thanks in advance!

At least with SDG&E, the true-up period doesn't change if you change rate plans... your monthly credits and costs will be calculated each month individually depending on the rate plan you had in effect during that month. I would guess that SCE handles it the same way. At the end of the true-up period, all of the monthly totals are combined, and any net kWh will be paid out at a nominal rate, and any $ credits are wiped clean. Any $ owed are, of course, billed at that time.

It will take about a week to two to switch plan.

Depends on how you design your solar sizing and orientation. If you design to cover 100% usage, then any plan will do. In general, TOU is good for solar owner.

Depending on orientation,. an 11 kW array will generate something like 16,000 to 18,000 kWh/yr., sort of close to your ~~ 20,400 kWh/yr. If you manage to drop usage to cover 100%w/solar, as Silversaver notes, it won't make much diff. which tariff you're on - you'll still zero out your bill and get ~~ $0.04/kWh for the excess.
