An expression for the uncertainty introduced by the discrete sampling
The maximum power produced by a solar cell is commonly determined by measuring the solar cell''s J-V curve as a series of discrete J-V points, and finding the point with the highest power. Since the J-V point with the highest power might not coincide with the actual maximum-power point of the J-V curve, there is an associated uncertainty in the calculated maximum power.
