pvlib.ivtools.utils.rectify_iv_curve(voltage, current, decimals=None)[source]#

Sort the IV curve data, remove NaNs and negative values, and combine points with duplicate voltage.

Parameters:

voltage (numeric [V])
current (numeric [A])
decimals (int, optional) – number of decimal places to which voltage is rounded to remove duplicated points. If not specified, no rounding is done.

Returns:

Notes

rectify_iv_curve ensures that the IV curve lies in the first quadrant of the (voltage, current) plane. The returned IV curve:

increases in voltage
contains no negative current or voltage values
contains no NaNs
contains no points with duplicate voltage values. Where voltage values are repeated, a single data point is substituted with current equal to the average of current at duplicated voltages.
