Question: what is the max available output current of a single string of solar cells would look like versus time, on a body-mounted solar array, for a cylindrical spin-stabilized spacecraft that is rotating at 30 rpm. The cell strings run lengthwise on the cylindrical body. sketch the above answer on a plot where the vertical axis of the plot is current(I), and the horizontal axis is time(t). Normalize the maximum value to 1.0A, and show 2 rotations worth of waveform. A sketch of the waveform is fine, it does not need to be mathematically exact, the general shape is the goal.

Then, choose two different points in time on your waveform, and for each: draw a cartoon of the sun vector and the position of the single string on the cylindrical spacecraft.
