We created a photovoltaic (PV) powered plug-in hybrid electric vehicle (PHEV) which is equipped with PV modules that have output power of 860 W. The integrated PV comprised of triple-junction III-V-based solar cells which conversion efficiency is approximately 34%. The public road tests were conducted to experimentally confirm the benefits of the vehicle integrated PV modules for one year. The measured results showed that the number of plug-in charging can be reduced greatly which increase the convenience of the battery-based vehicles by the integrated PV module. Even energy self-sufficiency was achieved for the neighborhood driving patter. In addition, the results suggest that the annual PV-powered driving range reaches 6211 km by the PV module. Since the average annual driving range of the passenger car in Japan is 10000 km, it was experimentally confirmed that 62% of CO2 emission from passenger car can be reduced by installing the PV module.
