An optimal compromise between energy efficiency and aesthetics for PV in the built environment sometimes requires to divide the PV field into sections with different orientation and tilt each, which are connected to a single inverter. From the experience and data collected through a year of monitoring the 2-Kwp photovoltaic grid-connected system installed on the flat roof of the High Technical School of the University of Jaen, some charts are presented to help architects, engineers and installers to select the most suitable inverter for two specific architectural solutions addressed to Integrating PV in buildings. However, charts for other sites, climates and architectural designs can he easily obtained.
