The tilt of earth axis, described in the earlier video, create seasonal variation in available solar radiation. In this video we  go deeper and  show that the further apart from the equator you are, the larger are the seasonal variations. To be able to do solar calculations you also need to know the time of the day and hence you need to understand the difference between solar time and clock time.
