You've got your directions backwards.

7pm in NYC is 4pm in SF, so you wanted to use solar power to provide evening energy then you generate in the West (SF) to power the East (NY).

And if you want to provide morning energy then they are correct.

In which case it wouldn't be "still light" it would be "already light"
