Covering highways with solar panel roofs could offer significant benefits in terms of safety and carbon emission reductions, a new analysis suggests.. Based on the highway data with a total mileage of 143,684 km at the end of 2020, the results show that the annual PV potential is 3,932 TW and that the corresponding installed capacity is 700.85 GW, which can generate clean electricity at a rate of up to 629.06 TWh.. Currently, most solar panels will work at approximately 50% efficiency during foggy conditions. This is vastly superior to solar panels operating in dense cloud cover or during overcast days; in these situations, the panels will be unable to capture much sunlight and generate power.. As an emerging energy harvesting pavement technology, the photovoltaic (PV) pavement, which combines mature photovoltaic power generation technology with traditional pavement facilities, can make full use of the vast spatial resource of roadways.. A solid design for highway solar roofs is the first step to harnessing the sun’s power, which engineers can determine through continued pilot projects. Utilizing grassy, flat median strips — otherwise rendered unusable — is another strategy they can assess to avoid taking up new land. [pdf]
