[0042] Attached below Figure 1-5 The present invention is further described. The following examples are only used to describe the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.
[0043] In the present invention, the effectiveness of the method of the present invention is verified by collecting the measured I-V curve data of a certain type of photovoltaic module in a photovoltaic power station.
[0044] Step 1: If Figure 4 , is the equivalent circuit diagram of the single diode model of the photovoltaic cell; according to the photovoltaic cell model, the five-parameter model of the photovoltaic module shown in the following formula can be established to determine the parameters to be identified:
[0045]
[0046]
[0047] In the formula, I is the output current of the photovoltaic module; V is the output voltage of the photovoltaic module; ph is the photogenerated current; I 0 is the reverse s...
