IEA-PVPS Task 13: Performance, Operation and Reliability of Photovoltaic Systems (Working period 2018 - 2021)

The IEA Task 13 develops independent, internationally valid analyses and recommendations for the operation and reliability of PV systems and their components. The continuation of the Austrian participation ensures the flow of information back to the Austrian photovoltaic industry through international cooperation and strengthens Austria as a location for innovation and production.

Short Description

The international experts in Task 13 collect and analyze relevant experience, information and data and disseminate this knowledge to provide a basis for technical evaluation and practical recommendations for action.

Content and objectives

Project objectives are (1) to analyze the current technological innovations from material and module to system level in terms of performance and lifetime, (2) to determine – based on large operational data sets of PV systems - given uncertainties in the analysis and their effects, (3) to identify and quantify technical risks of operation & management, and to develop guidelines for optimized, coordinated operation and maintenance strategies.

The results are (4) disseminated to actors from the industry and financial sector as well as to the public.

Method and approach

The work within the Task 13 is organized in three topical subtasks reflecting the first three objectives stated above. Given the broad, international project consortium, cooperation includes markets such as the Asian and Pacific Region, Europe, and the USA. The fourth subtask, dissemination, utilizes the output and disseminates the tailored deliverables by means of workshops and conferences, and comprehensive reports.

The Austrian Partner PCCL leads (together with Sandia NL, USA) the Subtask 1, focusing on new materials and compounds in recent module developments. AIT and OFI are engaged in many activities of performance evaluation and failure detection in the field, with a focus on electrical and material on-site analysis, respectively.


T 13-10 – from the title page of the review report about infrared (IR) and electroluminescence (EL) methods for field investigations - depicts outdoor EL imaging results showing PV modules with parallel resistance degradation.

Because of the very positive feedback on the Task 13 events and reports, the rapidly evolving PV applications, and therefore need for handling PV-quality issues worldwide, it was decided to extend the international Task 13 collaboration with an adapted Workplan again (Working period 2018-2021), to which the Austrian partners contributed extensively, and thus also ensuring the knowledge transfer to the Austrian stakeholders.

The task is being continued in working period 2022 - 2025.
