What is the relationship between the photovoltaic (pv) output and time (t) in a solar panel system?

The relationship between the photovoltaic (PV) output and time (t) in a solar panel system is that the PV output varies depending on the amount of sunlight available at different times of the day. The output is typically highest when the sun is at its peak, and decreases as the sun sets or if there are obstructions blocking sunlight.
