Embodiment Construction

[0019] The specific implementation manners of the present application will be described in further detail below in conjunction with the accompanying drawings.

[0020] The solar photovoltaic cell maximum power tracking method proposed in this application, such as figure 1 shown, including the following steps:

[0021] Step S11: Receive the collected measuring point data.

[0022] The measuring point data of solar photovoltaic cells is collected by the DCS (Distributed Control System) system, including light intensity, ambient temperature, voltage intensity, current intensity, etc.

[0023] After receiving the measuring point data collected by the DCS system, the measuring point data is converted according to the set unit. Specifically, the setting unit of the light intensity is watts / square meter, the setting unit of the ambient temperature is Celsius, and the setting unit of the voltage intensity is The setting unit is volts, and the setting unit of current intensity is amp...
