Validation of shading model in SolarMoves

To understand the impact that vehicle integrated PV can have on the electricity grid requirements now and in the future the SolarMoves project is using a combination of detailed modelling and measurements to arrive at predictions for the European EV fleet and grid infrastructure requirements now and in 2030. The first phase of the project consisted of extensive modelling [1]. In this paper we take vehicle irradiance measurement results from phase two of the project to examine the validity of the seasonal shading model used in part one of the project. Measurement results indicate that shading losses can be somewhere between 5 and 20 %. Shading can have a significant impact on PV yield, especially on VIPV where the vehicle is moving through different terrains, including open spaces with little shading to very densely built up areas with a lot of shading. Taking account of this in an accurate way is a very important part of determining the possible PV yield.
