Alignment and interconnection of photovoltaics on electric and hybrid electric vehicles

In this paper we discuss the alignment and system structures of photovoltaics on the roof of electric vehicles (EVs) and hybrid electric vehicles (HEVs). We focus on the interconnection of PV cells. In general, the position of photovoltaics on the roof of automobiles is crucial and has a strong impact on the photovoltaic (PV) output behaviour, in particular their output power level. We present strategies which allow the adaption of system structures according to changes in environmental conditions. As a result, we increase output performance levels by changing the interconnection of photovoltaics dynamically.
