Making sure your solar panels are working at their Maximum Power Point (MPP) is particularly important so that you can make sure you're optimising the value of your panels. First, we need to understand that solar PV modules generate DC power through the conversion of sunlight to electricity.
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.
The solar panel contains a matrix of solar cells that converts the sun irradiation to power. Connecting more cells in a matrix delivers more power but only 23 – 40% of the maximum power. The MPPTs (maximum power point trackers) are made to push the solar panel to work at the power curve's maximum power point.
The output of the panel will be anywhere along the curved black line. The left-most point of the graph is the Short Circuit Current (Isc), the point at which amperage is at its maximum and voltage is zero. Below that point on the y-axis is the Imp, which is the ideal operating current of the panel.
Left of that on the x-axis is the Vmp, which is the ideal operating voltage of the panel. As with the Isc, while it is possible for the voltage to be higher, the lower current past the Vmp produces a lower overall wattage. The ideal point for the panel to operate at is the Maximum Power Point (MPP, the intersection of the Vmp and Imp).
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 V t = n k T q to simplify the notation in the derivation, where kT/q ~ 0.026 volts and n is the ideality factor. The ideality factor varies with operating point.
