Oh, I'm certain, all right, at least for E6. I've been watching and analyzing my E6 bills carefully for four years. I'm sure E9 works the same way, because the E9 tariff wording is the same as E6 on that matter.

Actually, the E9 peak rate applies from 2 PM to 9 PM weekdays in the summer. The E6 peak rate applies from 1 PM to 7 PM weekdays in the summer. Since a typical solar array produces its maximum power around 1 PM in the summer and stops producing around 7 or 8 PM, you can sell more power at peak rate using E6 than E9.
In fact we usually start using more than we are generating around 5 or 6 in the evening (especially May to July), so having peak from 7 PM to 9 PM hurts us. The switchover comes even earlier by August, because the days are getting shorter but we're using more air conditioning. And as leaf561 pointed out, E6 goes off-peak at 9 PM, while E9 doesn't go off-peak until midnight, so that's three more hours of partial peak which also hurts us.

No, I've never spoken to them. I just trust what their official tariffs say.
