THE POTENTIAL OF PV-CARPORTS TO COVER THE ENERGY DEMAND OF ROAD PASSENGER TRANSPORT

摘要

Transport accounts for 31% of Swiss green house gas emissions due to the high degree of oildependence in transport energy supply. The emissions of transport could be reduced significantly if all the vehiclesthat ran on fossil fuels would be replaced by electric vehicles powered by photovoltaic solar energy. Compared toother sources of renewable transport energy, photovoltaic generation of electricity has two advantages: It requireslittle space and can also be applied to built-up areas or transport infrastructure. In this paper, we will examine thepotential of parking lots for the photovoltaic generation of solar electricity. The paper is based on simulations thatwere carried out for 48 parking lots in Frauenfeld, a typical medium-sized Swiss city of 22.665 inhabitants. Coveredwith solar carports, these parking lots alone would cover 15% - 40% of the energy demand by the city′s roadpassenger transport.
