Photovoltaic modules include, but are not limited to, photovoltaic cells, back sheets, glass, aluminum frames, cables, connectors, potting material, and the like. Sunlight irradiates the photovoltaic module in daytime to generate direct-current voltage, light energy is converted into electric energy and then is transmitted to the control cabinet, and electricity transmitted by the photovoltaic module is transmitted to the storage battery for storage through overcharge protection of the control cabinet, so that the photovoltaic module can be used when needed.
Photovoltaic inverters include, but are not limited to, fuses, power switching tubes, inductors, relays, capacitors, display screens, fans, heat sinks, structural members, and the like, through electrical connections. Photovoltaic inverters change a dc input into an ac output by regularly letting switching elements, such as power switching transistors, repeat on-off. In general, high-frequency pulse width modulation is required to narrow the voltage width near both ends of the sine wave, widen the voltage width in the center of the sine wave, and always make the switching element operate in a direction at a certain frequency in a half period, so as to form a pulse train. The pulse wave is then passed through a simple filter to form a sine wave.

The system has the functions of automatic operation and shutdown, maximum power tracking control, single operation prevention (for a grid-connected system), automatic voltage adjustment (for the grid-connected system), direct current detection (for the grid-connected system) and direct current grounding detection (for the grid-connected system). The automatic operation and shutdown functions refer to: after sunrise in the morning, the solar radiation intensity is gradually enhanced, the output of the solar battery is also increased, and when the output power required by the work of the photovoltaic inverter is reached, the photovoltaic inverter automatically starts to operate. After the photovoltaic inverter is started to operate, the output of the solar cell module is monitored at any time, and the photovoltaic inverter continuously operates as long as the output power of the solar cell module is larger than the output power required by the operation of the photovoltaic inverter; and the photovoltaic inverter can operate even in overcast and rainy days until the sunset stops. When the output of the solar cell module becomes smaller and the output of the photovoltaic inverter approaches 0, the photovoltaic inverter becomes in a standby state.
The maximum power tracking control function refers to: the output of the solar cell module is a function of the intensity of the solar radiation and the temperature of the solar cell module itself (the chip temperature). In addition, since the solar cell module has a characteristic that the voltage decreases with an increase in current, there is an optimum operating point at which the maximum power can be obtained. The intensity of solar radiation varies, and obviously the optimum operating point also varies. With respect to these variations, always having the operating point of the solar module at the maximum power point, the system always obtains the maximum power output from the solar module, which is the maximum power tracking control. The inverter for the solar power generation system has the greatest characteristic of comprising the function of Maximum Power Point Tracking (MPPT).

The energy storage device is very important for small-sized wind turbines which independently operate, and the energy storage mode comprises heat energy storage and chemical energy storage.
In specific implementation, the solar cell array is arranged in the photovoltaic power generation device. The solar cell array is a device for converting solar energy into electric energy, and consists of a plurality of solar cell panels, so that the solar energy can be converted into direct current electric energy.
