To gain the maximum amount of power from the solar cell it should operate at the manximum power voltage. The maximum power voltage is further described by V MP, the maximum power voltage and I MP, the current at the maximum power point. The maximum power voltage occurs when the differential of the power produced by the cell is zero.
A solar cell can operate at many current and voltage combinations. But a solar cell will produce maximum power only when operating at certain current and voltage. This maximum power point is denoted in figure 3.4 as Pm. Normally, the maximum power point for a I-V curve of solar cells occurs at the ‘knee’ or ‘bend’ of the curve.
The maximum power voltage is further described by V MP, the maximum power voltage and I MP, the current at the maximum power point. The maximum power voltage occurs when the differential of the power produced by the cell is zero. Starting with the IV equation for a solar cell: I = I L - I 0 e V V t
Since it is maximum power or peak power, it is sometimes also referred as Wpeak or Wp. A solar cell can operate at many current and voltage combinations. But a solar cell will produce maximum power only when operating at certain current and voltage. This maximum power point is denoted in figure 3.4 as Pm.
A single solar cell cannot produce enough power to fulfill such a load demand, it can hardly produce power in a range from 0.1 to 3 watts depending on the cell area. In the case of grid-connected and industrial power plants, we require power in the range of Mega-watts or even Giga-watts. Thus, a single PV cell is not capable of such high demand.
Normally the value of the cell parameters are given by a manufacturer or scientist at standard test conditions. (STC) which is corresponding to 1000 W/m2 of input solar radiation and 25°C cell operating temperature. Short circuit current (I SC): It is the maximum current a solar cell can produce. The higher the I SC better is the cell.
Parameters of a Solar Cell and Characteristics of a PV Panel
The solar cell produces maximum output power for given sunlight when the angle of the light and the cell are perpendicular to each other (i.e. 90 o) as shown in figure 3. When the angle of the incident of light is less than or greater than 90 o as shown in figure 3 than it will produce output power lower than the maximum output power capability ...

How to measure the maximum power of a solar panel
Assuming the current/voltage relationship is linear (it''s not, but this gives you a crude lower bound), you could measure the short-circuit current and the open-cell voltage and do 1/4 * I * V to obtain the maximum theoretical power given a worst-case 0.25 fill factor. However a more reasonable value might be obtained by using a different factor
