“…There might be instances when the vehicle battery is fully charged and therefore cannot receive any more energy. This leads to a potential overestimation of solar energy yields within this study [49,50]. Other neglected aspects (for comparability purposes) were temperature influences and battery self-consumption [17].…”

Recent developments in vehicle-integrated photovoltaics (VIPV) offer prospects for enhancing electric vehicle range, lowering operating costs, and supporting carbon-neutral transport, particularly in urban settings. This study evaluates the solar energy potential of parking spaces in Berlin, considering challenges like building and tree shading using digital surface models and weather data for solar simulations. Utilizing open datasets and software, the analysis covered 48,827 parking spaces, revealing that VIPV could extend vehicle range by 7 to 14 km per day, equating to a median annual increase of 2527 km. The findings suggest median yearly cost savings of 164 euros from reduced grid charging. However, the environmental benefits of solar vehicle charging were found to be less than those of traditional grid-connected photovoltaic systems. The study introduces a method to pinpoint parking spaces that are most suitable for solar charging.

“…The calculation of the extended driving range is likely an overestimation since it does not include losses due to battery saturation 34 : When the battery is already full, solar charging will not contribute to the driving range, thus increasing solar losses. This effect is of course very dependent on the size of the battery, the solar resource but also the charging strategy, for example, not filling the battery overnight to allow some solar charging during the day.…”

Solar‐powered vehicles have the potential to reduce CO2 emissions, operational costs and charging frequency needs of electric vehicles. This potential will depend on the local solar irradiation but also shadowing conditions, a relevant issue for urban contexts. The potential of solar‐powered vehicles in the urban context is modelled for 100 cities across the world showing that the median solar extended driving range is 18 and 8 km/day/kWp for driving and parked vehicles, respectively. The most favourable geographies include Africa, the Middle East and Southeast Asia; nonetheless, solar‐powered mobility has relevant potential across the full sample, including China, Europe, North America and Australia.Highlights Urban VIPV potential is assessed for 100 cities across the world. Solar extended driving range varies between 11 and 29 km/day/kWp. Charging frequency ratio ranges from 0% to 80%, with a median of 57%. Urban shadowing reduces driving range by about 25% for driving vehicles.

“…On the opposite side, if the EV battery is almost fully charged before the parking session, the PV contribution to the driving range will be less relevant whilst the increased AC load will be the same, and therefore the critical parking time is going to be even shorter. This is known as the full-battery effect [ 27 ]. In addition, the increase in temperature resulting from the prolonged parking periods in the sun can lead to a decrease in the car's battery performance and shorter life or even an increase in system energy consumption as the battery pack should be kept within the 15 to 35 °C range [ 28 , 29 ].…”
