Description

technical field [0001] The invention relates to photovoltaic solar technology, in particular to a photovoltaic solar pavement structural unit, a power generation system and a manufacturing method of the structural unit. Background technique [0002] At present, research on road solar energy at home and abroad mainly includes two aspects: the influence of solar energy on road surfaces and its development and utilization. Among them, the influence of solar energy on the pavement mainly studies the influence of solar radiation on the pavement temperature field and the resulting changes in pavement performance, including warpage and fracture caused by thermal expansion and contraction of cement concrete pavement, and high temperature rutting and low temperature of asphalt pavement. Problems such as cracking and UV aging have been studied for more than 50 years, and are still hot topics in the field of pavement engineering research. [0003] There are three main methods of solar...

Problems solved by technology

[0004] For the photoelectric conversion method, although it is currently used in road engineering, it is mainly to install photovoltaic solar panels outside the road surface without contact with traffic and pedestrians, such as lampposts, anti-collision walls, curtain walls, sound barriers or Canopy and other structures are used for power supply of traffic signal lights, guidance systems, monitoring systems, street lamps and lighting systems, so the solar energy collected by them is limited, and the huge amount of solar energy within the space of road buildings cannot be fully utilized
