Analysis on technical performance of the PV systems - Monitoring report

The overall objective of the monitoring task addresses three main issues: performance, grid interaction and social acceptance. Social acceptance is a long term activity which is being developed. Diffusion of monitoring results is expected to increase social awareness and public acceptance of renewable energy sources. On the other hand, grid interaction studies are also being developed, although with system sizes below 100kWp, it is probably not particularly useful.

Finally, performance monitoring is a key issue for grid connected PV systems, particularly those with complex designs and sited in the urban environment. In that sense, it is important to take into account that building integration constitutes one of the most challenging aspects of photovoltaic industry. Monitoring studies are expected to provide helpful information on PV performance to research laboratories, system designers and public organisations. Thus, the behaviour of systems considered must be analysed in terms of operational performance and reliability, paying special attention to the fulfilment of the expected results, so that the suitability of the installation procedure can be evaluated.

Different fundamental aspects are addressed in the current work:
- Monitoring guidelines are developed to be used in the system design process, so the photovoltaic operation of photovoltaic utilities can be analysed. Thus, it was necessary to specify those details regarding data collection and their evaluation.
- A system performance assessment procedure is developed to be in agreement with EU technical documents. In particular, the evaluation procedure is based on the European Guidelines and the International Electrotechnical Commission (IEC) Standard 61724 titled "Photovoltaic system performance monitoring - Guidelines for measurement, data exchange and analysis".
- Monitoring data gathered from the different utilities are presented in graphs and tables in order to allow comparison between different PV plants in the project.

This result is now complete and the report is available form inspection on request and can be used for further work in this field providing that reference is made to the eUnivresol project and the authors of the result.
