Sun power on a hot day
By walterbays on Sep 04, 2007
Yesterday SDG&E hit an all-time record demand of 4,636 MW. Although my solar panels hit their peak production in the early afternoon, already by 8am they were producing twice as much energy as my house was using, and the gap is steadily rising. Peak demand for SDG&E is from 4 to 6 pm. Though that's past the peak of my panels' production, my house remains a net generator of electricity through 6pm when it finally begins drawing power from the grid.
