My grid tied PV system is 6.4 kW with SDG&E and has produced over 10,000 kWh's over the past year. I have just finished my first true-up period on my system which started in Sept 2016 and ended Aug 29, 2017. I opted into TOU Plus for one year with a guaranteed refund if it cost more than the Standard DR rate. My system was designed to zero out my electric bill and I ended with over 3400 kWh's. Here is the comparison between the TOU and Standard DR rates:

As you can see the differenc is $32.34 in favor of TUO plus over standard DR. There are two large differences. One in April and one in August. The former is due to the California Climate Credit in April and the difference in compensation for excess generation in August. You will note that the charges for the other months differ by only a few cents or are equal.
