Abstract

The aim of this project is to show the technical possibility of the use of photovoltaics to provide energy to a car. It has been implemented on the Heverlee campus of the University of Leuven and consists mainly of an array, a test cabin and an electric car. The array was entirely made in the ESAT laboratory, using its original integral screen printing technique for the cells. For several reasons the electric car chosen was the PGE 5P TAXI (Milano, Italy). Out of the daily performed measurements during the months of July and August, we could conclude the following: + the reliability of the array and the loading system appeared to be very good. + the system efficiency is relatively low. This is due to several reasons: + the loading voltage is not always equal to the optimum voltage Vm + the interconnection of several modules results in a decreasing total efficiency (it is determined by the worst module). + the temperature rises during the day (giving a lower efficiency) + the poor condition of the batteries resulted in a practical range of no more than 30 km. We can conclude that solar electricity is for the moment only economically viable for small-scale purposes in remote areas. As a general conclusion we can state that the technical possibility of the project is proven, yet there can still be done a lot of work on increasing the reliability of electric cars.
