The world's first section of a highway carrying photovoltaic pavement has generated nearly 100 days of electricity

The world's first highway carrying photovoltaic pavement was officially put into operation
in Jinan, Shandong Province at the end of last year.
At present, the electricity generated by this photovoltaic road surface has been connected to the charging pile to realize grid-connected power generation, and has realized the functions of providing power supply for highway street lights, electronic information boards, snow melting agent automatic sprinkler facilities, tunnels and toll stations, and has generated about 100 days of cumulative power generation so far, with a cumulative power generation of 87,920 kWh
.

The total length of the test section of the photovoltaic highway section is 1120 meters, located in the Jinan South Ring Expressway, the length of photovoltaic pavement is 1080 meters, the total laying area is 5874 square meters, and the total installed peak power is 817.
2 kilowatts, which is the world's first highway with the highway as the carrier to realize multi-vehicle road photovoltaic power generation under high load and high flow complex traffic conditions, and it is also the prototype of the future transportation industry upgrading product - "super highway
" 。 The three-layer structure of "transparent concrete + photovoltaic power generation module + insulation protection" is adopted in this section of photovoltaic pavement, and the surface is in contact with vehicle pedestrians with a protective layer, and "transparent concrete" is used, which can carry the driving of small electric vehicles; The middle layer is the original layer of power generation, and the laid photovoltaic power generation modules can generate electricity; The bottom layer is an insulating layer
that insulates the moisture below.

According to reports, the test section has been operating so far, with an average daily traffic volume of more than 40,000 vehicles, after the peak of spring traffic and snowfall and snowmelt weather, it has not affected its road performance, reflecting good bearing capacity and anti-slip performance, and meeting the relevant requirements
of China's expressway for the road surface and the entire road.
Photovoltaic pavement modules also show good durability and do not cause abnormalities due to normal traffic
.
Qilu Transportation Group has also learned about the driving experience of citizens, and received feedback that the photovoltaic road surface is smoother, the driving is comfortable, and the tire noise is not significantly different
from the traditional asphalt road.
From the perspective of power generation, the photovoltaic pavement test section experienced various weather types such as haze, snow, rain and other weather types during operation, encountered the special situation of high-voltage power grid power outage maintenance, and the deployment of electricity peak during the Spring Festival, and the overall power generation situation reached expectations, and the related equipment operated well
.
Up to now, the cumulative power generation has been about 97 days, and the cumulative power generation is 87,920 kWh
.

At present, the photovoltaic pavement has realized the functions of providing power supply for highway street lights, electronic information boards, automatic sprinkler facilities for snow melting agents, tunnels and toll stations, and the surplus electricity is on the Internet
.
With the upgrading of technology and the integration of related industries, photovoltaic pavement will gradually realize functions such as electronic sign marking, automotive mobile wireless charging, road electric heat and snow melting, Internet coverage, big data integration and analysis
