Embodiment
[0046] to combine figure 1 , the intelligent management method of a kind of photovoltaic module of this embodiment, comprises the following steps:
[0047] (1) Real-time collection of external information of photovoltaic modules, the external information includes current value, voltage value, temperature value and solar irradiance;
[0048] (2) Obtain the corresponding actual I-V characteristic curve according to the external information of the photovoltaic module collected above;
[0049] (3) Determine whether the actual I-V characteristic curve conforms to the theoretical I-V characteristic curve. If it exceeds the set error value, use the principle of natural law to further analyze the abnormal type; if it does not exceed the set error value, it means that the photovoltaic module is working normally. Repeat the above steps (1) to step (3); the above-mentioned principles of natural law are fuzzy principle, the same probability principle and the monotonicity principle of sol...
