Integrating solar photovoltaics in electric vehicles can reduce operating costs and extend the driving range. It is particularly appropriate for urban mobility due to the relatively short typical daily travels of urban vehicles. However, shadowing cast by buildings will reduce the solar irradiation falling on the vehicle, reducing its PV generation. This study assesses the solar potential of onboard solar for roads and urban parking using data in a geographical information system for the case study of Lisbon. Results show that annual losses due to shadowing may reach 25% for roads and over 50% for urban parking spaces. Nevertheless, despite these losses, the annual solar extended range for onboard solar vehicles is between 10 and 18 km/day/kWp, thus significantly reducing charging needs.

将太阳能光伏电池集成到电动汽车中可以降低运营成本并扩大行驶范围。由于城市车辆的典型日常行驶时间相对较短，因此特别适合于城市交通。但是，建筑物投射的阴影会减少落在车辆上的太阳辐射，从而减少其PV产生。这项研究使用地理信息系统中的数据，以里斯本为例，评估了道路和城市停车用车载太阳能的太阳能潜力。结果表明，由于阴影造成的年度损失在道路上可能达到25％，在城市停车位上可能超过50％。尽管如此，尽管有这些损失，车载太阳能汽车的年度太阳能扩展范围仍在10至18 km / day / kWp之间，从而大大减少了充电需求。
