The conversion of solar energy in electric energy using photovoltaic (PV) systems is one of the best and most commonly used types of renewable energy sources. Although PV technology is mature, continuous improvement of its performance, reliability, and cost are necessary for wide-scale adoption of PV.

There are several factors and parameters influencing the development and performance of PV devices and systems. The advance of the PV modelling and simulation tools on the one hand, and measurements, monitoring, and analysis procedures on the other, for different types and locations for PV systems, can lead to improvement of their performance. Additionally, these results can be used successfully for designing and identifying the best solutions for the new photovoltaic installations.
