In the P-V graph (see below), X axis define measured voltage value for each step, left Y axis define measured
current value, and right Y axis define measured power value.
The meanings for fields at the bottom of graph,
Imax - maximum measured current.(@ at the right is its value of X axis)
Imin - minimum measured current.(@ at the right is its value of X axis)
Pmax - maximum measured power.(@ at the right is its value of X axis)
Pmin - minimum measured power.(@ at the right is its value of X axis)
I - cursor values of left Y axis for measured current in blue color
P - cursor values of right Y axis for measured power in green color
The meanings for fields at the right side of graph,
Voc - open-circuit measured voltage.
Isc - short-circuit measured current.
Vmp – measured voltage at maximun power.
Imp – measured current at maximum power.
Pm – measured maximum power.
FF – fill factor(%)
