How much power does a photovoltaic Highway generate in China?

By 2020, the mileage of Chinese highway was 143,684 km and the area was 3,957 km 2. The installed capacity and power generation of PV highways in China are 700.85 GW and 629.06 TWh, respectively. Installing photovoltaic (PV) modules on highways is considered a promising way to support carbon neutrality in China.

Are PV highways a viable option in China?

According to the findings of this research, PV highways in China offer a significant amount of PV potential. However, PV highways are not yet being promoted or used to a large extent at this time. Installing PV panels on highway surfaces is associate with many technical challenges that need to be overcome.

What is the solar energy potential of highways in China?

The annual solar energy potential of Chinese highways at the prefecture-level city scale. According to the obtained results, the highway solar energy potential in China is 3,932 TW. Fig. 9 shows that cities with high highway solar energy potential is mostly located in the northwest, north, and south-central parts of China.

When was the first PV highway built in China?

In China, the first PV highway was constructed in Jinan in 2017 . Despite the fact that the PV panels on the carriageways were removed after a year, the PV panels in the emergency lane remain operational .

Are PV panels still operational in Hangzhou -Shaoxing-Ningbo smart highway?

Despite the fact that the PV panels on the carriageways were removed after a year, the PV panels in the emergency lane remain operational . The Hangzhou-Shaoxing-Ningbo Smart Highway, a superhighway incorporates PV panels, is also under construction and scheduled to open in 2022 .

Is PV pavement a good investment in China?

Considering the electricity price for industrial consumers in China is 0.14 $/kWh, the investment in PV pavement even can never be paid back. This technology might not be economically attractive until the LCOE is lower than 0.2 $/kWh .
