N1 - Funding Information: The authors thank the German Federal Ministry for Economic Affairs and Energy for funding this work under grant FKZ 0324275 (Street), and the state of Lower Saxony for institutional funding. The authors especially thank Continental Engineering Services (CES, Nordostpark 30, 90411 Nuremberg)—Robert Steib, Andreas Semmelmann, and Stefan Lutz—for their dedicated and excellent work on the integration of the VIPV components into the vehicle. The authors also thank Sascha Wolter for his help with the data analysis, Dirk Bartels for his work on the grid charging point, and Annika Raugewitz for her contributions to the planning of the test drives. Furthermore, the authors thank the IEA PVPS task 17 team, in particular Keiichi Komoto, for inspiring discussions. Open access funding enabled and organized by Projekt DEAL.

N2 - The setting up of a practical electrically driven light commercial demonstration vehicle with integrated photovoltaics (PV) is reported. The demonstrator vehicle is equipped with 15 modules based on the crystalline Si/amorphous Si heterojunction technology. The nominal total peak power under standard testing conditions is 2180 Wp. Specifically, the PV-converted energy is fed into the high-voltage (HV; 400 V) board-net for a utilization of the large capacity of the HV battery and thus for direct range extension. The demonstrator vehicle is equipped with irradiation, wind, temperature, magnetic, and global positioning system sensors. Irradiation and temperature as well as the energy flows from modules, maximum power point trackers (MPPTs), low-voltage buffer battery to HV battery via DC/DC, and from the HV battery to the loads during an exemplarily test drive day (May 31, 2021) are monitored. The range extension obtained at this day on our test route (51° 59′ N, 9° 31′ E) was 36 km, the corresponding CO2 savings account for ≈2.3 kg. The chain efficiency of the electronic components from the input side of the MPPTs to the HV output side of the DC/DC was 68.6%, whereas the DC/DC itself has an average efficiency of 90%.
