- pvlib.ivtools.utils.rectify_iv_curve(voltage, current, decimals=None)#
Sort the IV curve data, remove NaNs and negative values, and combine points with duplicate voltage.
voltage (numeric [V]) –
current (numeric [A]) –
decimals (int or None, default None) – number of decimal places to which voltage is rounded to remove duplicated points. If None, no rounding is done.
voltage (numeric [V])
current (numeric [A])
rectify_iv_curveensures 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.
