Sizing of Grid-Connected Photovoltaic System with Roof Space Constraint

The installation of building-integrated photovoltaic systems has increased over the past years. This paper presents the sizing method of photovoltaic systems with rooftop space as a constraint. A sizing tool is developed to assist the design of PV systems with roof space constraints by using Visual Basic for Application. This new sizing tool is developed by implementing an iterative technique and is able to optimize the quantity of PV panels while overcoming the problem of space constraints on the rooftop. A roof dimension from Google Maps is used for the case study. This tool minimizes the design process time for an integrated PV system with minimum information on a rooftop.
