International energy agency task II database on photovoltaïc power systems: statistical and analytical evaluation of PV operational data

Abstract

As a part of the International Energy Agency (IEA) Photovoltaic Power Systems Co-operative Programme (PVPS), Task II, the above mentioned participants are collecting and analysing operational data of photovoltaic plants in various system techniques (grid-connected, stand-alone, hybrid) located all over the world. The objective of this joint project is to provide PV experts and other target groups with suitable information on the operational performance of PV systems and their subsystems. The developed IEA database is designed to gather and standardise the operational data of PV systems applied to various uses in order to achieve an assessment of their performance on the same base. Detailed system characteristics of existing PV plants as well as operating results of the monitored PV systems are stored in this database and made available to the users. The analysis allows comparisons between existing PV systems in different countries with different climatic conditions, PV plants using various system techniques and PV systems of different consumption behaviour.
