I’d like to get the value of the dotted predicted production curve at specific points (yellow marks) so that I can calculate the red marked area.
This is so that, assuming the blue line is my expected consumption, I can “undercharge” my battery during the night (not charge it to 100%) so that by the time there is solar production, there is enough space to be filled by solar.
EDIT: Thinking about it, the blue curve should be a flat line, as this plot shows production in each hour, not comulated production. The question still stands.
