Study on the incorporation of photovoltaic systems as an auxiliary power source for hybrid and electric vehicles

► The use of PV cells as auxiliary power generators in vehicles is investigated. ► The suitability of PV technologies for vehicular applications is assessed. ► PV systems will provide energy continuously, even when the vehicle is parked. ► The annual fuel consumption of the vehicles will be reduced. ► The payback period of the initial investment would be approximately 4 years.
