Photovoltaic panels installed on Jingguang Bridge

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.

What is the capacity potential for large-scale solar PV in China?

4. Discussion This work reports that the total capacity potential for large-scale PV in China is 108.22 TW with 150.73 PWh annual solar PV generation (implying an average capacity factor of 15.9), which can bring 150.28 billion tones of CO 2 emission mitigation caused by coal-fired power generation.

Is solar photovoltaic power possible in China?

Some previous research has evaluated the geographic and technical potential of solar photovoltaic power in China (; ), in which only some basic geographic and climatological factors such as land-use type, slope, and solar radiation are considered.

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.

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 .

Can roofing solar panels increase electricity generation over secondary roads?

Additionally, we investigate the possible increase in electricity generation by roofing solar panels over secondary roads with broader geographical coverage and higher density (Figure S1b in Supporting Information S1 ). The annual electricity generation of the secondary-road PV is 13,570 TWh, corresponding to an installed capacity of 10,191 GW.
