If you have enough energy generated by your solar, it will eliminate the grid usage during Part-Peak and even export solar if available. When I had enough solar generation, my system would try to get to 100% before 3pm, the start of my Part-Peak period. Now that my generation is barely enough to cover my Peak usage, it allows the house to draw from the grid during that 3-4pm Part-Peak hour and just uses battery energy for the Peak period.Getting back to the Price Schedule settings, I'm curious how the Northern CA/PGE folks handle the partial peak period. I too, live in Northern CA, Oakland to be exact, and I entered the exact times for Peak (4 - 9) and Off-peak (12 - 3). Although you can't directly enter the time for partial peak, it appears that it still calculates it and shows it in the diagram. What I don't know is how it handles the partial peak time in terms of decisions about charging or sending back to the grid. Does it treat it like Peak, Off-peak, or some combination? I know some people just set Peak to include the partial peak time. How do others with PGE approach that?
You can see in the chart below, it stopped charging at 3:15pm and ran down to the Reserve at about 8:55pm.
Earlier in the fall when there was more generation, it got to 100% before 3pm and then let the surplus solar export. It also mostly powered the house through the evening Part-Peak until midnight.
