First of all, I'll just say that I haven't had to look at one of these since 1991
Did you change from an all-day fixed rate to TOU half way through the billing period, or perhaps the other way around?
There appear to be two 58 day periods, I assume the increased daily supply charge is for the 2nd half of the period, when you went to TOU? (Or perhaps you went from TOU back to a fixed rate? hard to say from what I can see there)
Does meter B1115155 have 2 registers? It appears to have 861.341kWh of PV generation, for which you have been credited $43.07.
The 2nd register on that meter appears to have had its readings divided into 2, approximately, as it doesn't quite add up, half peak, and half off-peak.
I have no idea what a Double Up Discount might be.
