This claim about peak power usage is untrue, at least for California. For the past 20 years in California, the annual peak electricity usage has ALWAYS occurred between 2pm and 5pm.: https://www.caiso.com/Documents/CaliforniaISOPeakLoadHistory.pdf https://www.caiso.com/Documents/CaliforniaISOPeakLoadHistory... I used to work at a power company as well. (It's true that the daily peak is in the evening and that won't be helped by solar. But capacity is built to handle the annual peak, not the daily peak, and because the annual peak tends to be hot afternoons, solar actually will replace other generation in the long run.)
