Quality and Reliability of PV Systems
Quality and reliability of PV systems is at the core of discussions during this year’s Intersolar Europe fair in Munich. While the PV market grew significantly in the last five years, the question of PV systems performance becomes central to continue lowering both the cost of PV electricity and the cost of financing PV installations.
Following four years of PV systems performance and reliability research, the IEA PVPS programme’s Task 13 has begun delivery on a series of five reports summarizing these years of intensive research activities. These reports focus on several aspects of PV performance and reliability and cover the main aspects of quality-oriented activities in the PV sector.
Three new reports focus on PV Performance and the impact of PV module failure, for both crystalline silicon and thin-film technologies. They show that the question of quality and reliability can be managed in a scientific way and that in recent years much progress has been made, in parallel with the growth of the PV markets and industry.
- These already available reports focus on the cause of failure of PV modules, the performances of thin-film technologies and the major specific differences for performance measurement compared to cSi technology and finally the last report details good practices for monitoring and performance analysis and provides guidelines to improve PV systems’ performances.
Two additional reports will be published in the coming months, focusing on the analysis of PV systems long-term performance and the degradation behaviour of PV modules in accelerated stress conditions. These reports will complement and close the first phase of this research programme with a consistent and complete set of scientific data that will help industries and financing bodies to better assess the real performance situation of PV systems today and in the near future.
Finally, these reports will be a landmark in PV Performance and Reliability assessment, building on the reputation of independence and quality of the IEA PVPS programme since 1993.
These reports are available here.
(New) Review of Failure of PV Modules
One key factor of reducing the costs of photovoltaic systems is to increase the reliability and the service life time of the PV modules. Today’s statistics show degradation rates of the rated power for crystalline silicon PV modules of 0.8%/year. To increase the reliability and the service life of PV modules one has to understand the challenges involved. For this reason, the international Task 13 expert team has summarized the literature as well as their knowledge and personal experiences on actual failures of PV modules.
The report can be found here.
(New) Analytical Monitoring of Grid-Connected PV Systems
This report focuses on the analytical assessment of photovoltaic (PV) plant performance on the overall PV system level. In particular, this report provides detailed guidelines and comprehensive descriptions of methods and models used when analyzing grid-connected PV system performance.
The report can be found here.
(New) Characterisation of Performances of Thin-Film PV Technologies
Although thin-film photovoltaic (PV) modules have been in production for decades, the characterization of their performance, both outdoors and under artificial light, remains a topic of active research. This is because the field contains a diverse set of PV technologies, each of which has physical differences from conventional crystalline silicon PV. These differences range from different temperature coefficients to complex short-term or seasonal transients in performance. This report summarizes the nature of these special behaviours and demonstrates best practices for handling them in the context of several case studies.

Photovoltaic and Solar Forecasting Report
This report provides a snapshot of the state of the art of solar and PV forecasts for time horizons ranging from a few minutes ahead to several days ahead. Diverse resources are used to generate solar and PV forecasts, ranging from measured weather and PV system data to satellite and sky imagery observations of clouds, to numerical weather prediction (NWP) models which form the basis of modern weather forecasting.

Rural Electrification with PV Hybrid Systems - 2013 (English / French)
- Rural Electrification with PV Hybrid systems - T9 - 11072013 - Updated Feb2014
- With decreasing PV prices, PV / diesel hybrid minigrids attract significant attention from institutions in charge of rural electrification and donor agencies - to mitigate fuel price increases, deliver operating cost reductions, and offer higher service quality than traditional single-source generation systems. The combining of technologies provides interesting opportunities to overcome certain technical limitations.
Written by Gregoire LENA (IED), this publication aims to present the state of the art situation of PV / diesel hybrid systems for rural electrification and to highlight the main remaining issues – from the design, technical and implementation perspectives.

The concept of pico PV systems and their application in real-world circumstances are explained. The importance of understanding the dynamics of the demand side of this market is clearly elaborated, as are the nature and supply of the products, their economics, and experience with various business models. There are clear lessons for the roles that should be played by governments, donor bodies and others in the markets for pico PV products and services,
essentially as providers of appropriate institutional frameworks and information.
