Abstract: As a part of the International Energy Agency (IEA) Photovoltaic Power Systems Programme (PVPS), the participants of Task 2 are collecting and analysing operational data of photovoltaic plants in various system techniques located world-wide. The objective of this joint project is to provide suitable technical information on the operational performance, reliability and sizing of PV systems and their subsystems to the target groups. People working in the area of photovoltaics like manufactures, system designers, utilities, research laboratories, standardization organizations and vocational schools may benefit from the group of international experts working on the analysis of monitoring data and giving feedback to the PV system design. Task 2 participants have developed a database containing PV system data selected from different kinds of application e. g. professional and domestic stand-alone systems, distributed grid-connected systems and centralized PV power plants. A detailed analysis of more than 260 PV systems has been carried out using normalized quantities allowing any kind of cross-comparison between different systems. In case of stand-alone systems, new parameters have been introduced to better quantify the system behaviour from a technical point of view and to define a ranking procedure. This paper will summarize and present the most important results drawn from the performance analysis of the 260 different PV systems addressed in the IEA PVPS Task 2 database.
