Definition and History of Photovoltaic Power Systems

Photovoltaic, that is, photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. The energy of the photovoltaic power generation system comes from the inexhaustible solar energy, which is a clean, safe and renewable energy source. The photovoltaic power generation process does not pollute the environment and does not damage the ecology.

The smallest unit for photoelectric conversion is a solar cell. Its size is 4~100cm2, the working voltage is 0.45~0.50V, and the working current is 20~25mA/cm2, so it cannot be used as a power supply alone.

The smallest unit for photoelectric conversion is a solar cell. Its size is 4~100cm2, the working voltage is 0.45~0.50V, and the working current is 20~25mA/cm2, so it cannot be used as a power supply alone. In a photovoltaic power generation system, solar cell monomers need to be connected in series, parallel and packaged to form a solar cell module. Its power can be from a few watts to hundreds of watts, and it can be used as a power supply alone. The solar cell array is to install the solar cell components on the bracket after being connected in series and parallel. It can output hundreds of watts, several kilowatts or even more power, and it is the electric energy generator of the photovoltaic power generation system.

Application Scenarios of Photovoltaic Power Generation System

In addition to solar power plants and distributed rooftop photovoltaics in traditional thinking, photovoltaics can also be applied to a variety of scenarios, such as construction, agriculture, fishery, public facilities, and landscape construction. On the one hand, these composite and cross-border models enable photovoltaic construction projects to take into account economic development and ecological protection while generating clean power; Land Resources.
