Thanks, I went to school too.

I said the time period matters when you're talking about it relative to generation. 30kWh over the course of a day is very different to 30kWh over ten minutes.

Um... My reply was to you saying "I'm sure GP understands that [explanation]"

Except that GP (pmontra) had asked "Is that 30 kW each hour of the day?"

Clearly someone asking that doesn't understand what kWh/day means, and since you were backing GP, it seemed reasonable to guess that you might not understand either.
