The total rate page which Drees has cited is quite helpful because it gives you the historical charges so you can compare the new and the old rates quite easily.
The short story is that EV-TOU rates all went up a couple of cents. If you have solar you'll notice the increase less because your peak production will be paid out at a couple of cents more and you'll pay a couple of cents more for off-peak and super off-peak. On the basic DR rate the higher usage levels went up quite a bit, more like seven cents. That would be noticeable. The solar companies have reported record interest and you can see why -- customers now have more reason to use solar to get out of the highest usage bands.
FWIW I think SDG&E has a very favorable plan for solar given the peak period is noon to six. If you have a solar system that's about as good as you can get other than something like 11 AM - 6 PM. Moving the peak period back during the day would not be very helpful. If SDG&E did that I think I'd just add another kW of panels and move back to the DR plan.
