THE COMPLETED IEC 61853 STANDARD SERIES ON PV MODULE ENERGY RATING, OVERV IEW, APPLICATIONS AND OUTLOOK

摘要

We present an overview of the IEC 61853 standard series "Photovoltaic (PV) module performance testing and energy rating" paying special attention to the last two parts (3 and 4) which were published in August this year. The standard defines a methodology to estimate the performance of PV modules considering real working conditions defined by six datasets representative of the major climatic conditions likely to be encountered by PV installations. The standard not only provides these climatic datasets (Part 4) and the models to estimate the PV performance (Part 3), but it also describes the methodology to test and measure the relevant characteristics of the PV modules under evaluation (Parts 1 and 2) so as to obtain the input data required by the said models. The output of the standard, the so called "Climate Specific Energy Rating" parameter (CSER), can be used to compare different PV technologies in terms of their performance under the same climatic conditions, or to compare the behaviour of a specific technology under the different climatic regions included in the standard, helping PV manufacturers, installers and investors to choose the most suitable PV technology for every location.
