Nuevos métodos de detección de suciedad para la mejora de la competitividad de sistemas fotovoltaicos

Resumo

The optimization of operation and maintenance tasks in photovoltaic (PV) systems plays a crucial role in cost reduction and performance enhancement of these systems. The main objective of this Doctoral Thesis is to propose novel approaches for monitoring the impact of soiling in PV systems. To achieve this, two distinct lines of research were pursued. Firstly, the characterization and validation of an innovative, cost- effective soiling sensor based on optical transmittance measurements were conducted. Secondly, various analytical methods were applied to estimate real-time electrical losses due to soiling. In conclusion, it was found that the soiling detection in PV systems can be potentially enhanced by employing either the low- cost optical sensor investigated or some of the evaluated analytical methods, which were validated with data from PV modules of different technologies.
