Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment, in particular to a foldable photovoltaic component. Background Art

[0002] Some work that requires construction or exploration in remote areas requires electricity supply. Since their work locations are not fixed and remote, it is very difficult to access the power grid. Using diesel generator sets to generate electricity consumes diesel, which produces noise and pollutes the atmosphere. It is also very difficult to transport diesel in remote mountainous areas. When an earthquake occurs and the regional power grid is interrupted and unable to provide power guarantee, it is necessary to quickly build a large-scale photovoltaic energy storage power station to provide power for rescue and disaster areas.

[0003] Traditional ground photovoltaic module installation is a complex process, including multiple steps: first, the foundation needs to be treated to ensure that the ground can bear the weight of the photovoltaic module; then the prefabricated foundation is built to provide a solid support for the bracket; then the photovoltaic bracket is installed to fix the photovoltaic module; then the photovoltaic module itself is installed on the rack; then the DC cable is laid to transmit the power generated by the photovoltaic module to the photovoltaic inverter; then the inverter is installed, which is responsible for converting DC power into AC power; if energy storage is required, the energy storage battery system needs to be installed. This series of processes not only requires a large amount of materials and equipment, but also has a long cycle from material organization to construction completion. For some temporary or rescue occasions, such as emergency power supply at disaster sites, this traditional installation method is not applicable because it is too time-consuming and has high requirements for materials and logistics.
