Description

A microarray photovoltaic battery pack solar road surface

technical field

The utility model mainly relates to road engineering, intelligent transportation technology and photovoltaic solar energy technology, in particular to a microarray photovoltaic cell group solar road surface.

Background technique

Solar pavement refers to a new type of pavement that uses photovoltaic solar energy-absorbing layers to replace traditional asphalt concrete or cement concrete surfaces, or lays photovoltaic solar energy-absorbing layers directly on the existing asphalt concrete or cement concrete pavement surface as a surface layer. The structure type can realize the development and utilization of solar energy on the road and the function of clean power generation without occupying additional land while ensuring the transportation function. Therefore, in the past ten years, solar pavement has received more and more attention and exploration at home and abroad, and it is also one of the important ways to realize the development of green transportation and smart transportation.

At present, solar pavement structure models at home and abroad generally adopt a plate unit structure. Usually, this plate unit can be divided into a three-layer structure from top to bottom: the surface light-transmitting protective layer, the middle photovoltaic solar cell energy-absorbing layer, and the bottom water-proof protective connection layer. This type of plate structure generally adopts a laminated composite solid plate structure, such as the "double-layer tempered glass plate + solar cell" hexagonal plate structure developed by Scott of the United States, and the "tempered glass plate + solar cell" of the Dutch Applied Scientific Research Organization Consortium (TNO) Solar cell + concrete plate" rectangular plate structure, French COLAS company's "silicone resin coating + solar cell + resin and polymer base plate" rectangular plate structure, etc. Due to the fact that this solid plate structure directly bears the driving load, it has high requirements on the compressive capacity of the solar panels and electronic components, and the placement angle of the solar panels cannot be adjusted. In China, we have proposed a hollow plate structure (patent 201410142523.X). Therefore, in the space where the thickness of the surface layer of the solar pavement is limited, how to consider the different solar elevation angles and route positions in different regions to meet the needs of the direction of sunlight irradiation, so as to improve the power generation efficiency of solar panels, is the key to be solved for the solar pavement One of the technical issues.
