Description

Technical Field

[0001] This application relates to the field of photovoltaic support technology, and in particular to a bridging module. Background Technology

[0002] The photovoltaic industry is a strategic emerging industry strongly supported by the state, and rooftop distributed photovoltaic power stations are receiving increasing support from national industrial policies and high attention from local governments. To ensure the safety and lifespan of rooftop photovoltaic power stations, photovoltaic mounting systems play a crucial role. With the increasing installed capacity of rooftop photovoltaic power stations, the installation efficiency of distributed photovoltaic mounting systems is attracting more and more attention in order to further reduce the cost per kilowatt-hour, decrease installation costs, and improve the revenue generated by rooftop photovoltaic power stations.

[0003] The application scenarios for rooftop distributed photovoltaic (PV) systems are mostly on building rooftops. Residential rooftops typically have large angles, meaning construction workers are performing high-altitude work, which poses certain risks during installation. Due to limited rooftop space, medium-pressure blocks are used to secure the modules. As module sizes increase, using medium-pressure blocks for large modules becomes increasingly problematic. Because of the large module size and limited roof space, workers often have limited arm span and must lie prone on the module to secure the blocks, potentially causing microcracks in the module, posing a risk of slipping, and resulting in low installation efficiency.
