Description

Technical field: [0001] The invention belongs to the technical field of prefabricated materials for road engineering, and in particular relates to a prefabricated component of a road surface integrated with solar photovoltaic light and heat and a power generation system. Background technique: [0002] As an important infrastructure in modern cities, pavement can account for 30%-45% of the city's surface area. Because it is exposed to direct sunlight all year round, the solar radiation energy absorbed by urban pavement is huge, up to 40MJ / m per day in summer 2 . It can be seen that the potential of collecting and utilizing solar energy in road space is huge. In addition, due to people's work and routine, urban roads often have few vehicles and pedestrians during periods of strong solar radiation, such as noon and afternoon, and most of the ground is directly exposed to the sun, with little shade; When it is weak, such as early morning and evening, urban roads are often crow...
