Evaluation of relative importance of factors affecting the performance of a local grid-connecting BIPV system by computer simulation

This paper will outline the results and findings produced by a simulation software developed by the university of Hong Kong PV research team (HKUPV) in evaluating the performance of different building integrated photovoltaics systems (BIPV) under different factors such as variable climate, tilt angle, wiring configuration and choice of inverters that affect the annual energy yield obtained from a grid-connecting BIPV system in Hong Kong with a rapid-changing sub-tropical climate. The relative importance of these factors ensuring optimal performance of PV system is shown through detailed analysis.
