If you put your solar powered math calculator in your backpack it will turn off from the lack of sunlight needed to power the device.

A 2-axis panel both follows the sun’s daily path as well as the seasonal differences

Weather is one of the major culprits that will cause inconsistent total peak sun hours for any given day. The sunrise and sunset will always be predictable every day, but the weather is hard to predict and cloud coverage can greatly diminish the efficiency of a solar power system on any given day.
