The Performance of Photovoltaic (PV) Systems: Modelling, Measurement and Assessment explores the system lifetime of a PV system and the energy output of the system over that lifetime. The book concentrates on the prediction, measurement, and assessment of the performance of PV systems, allowing the reader to obtain a thorough understanding of the performance issues and progress that has been made in optimizing system performance.Provides unique insights into the performance of photovoltaic systems Includes comprehensive and systematic coverage of a fascinating area in energy Written by an expert team of authors and a respected editor

温情杀手2020-05-15When calculating performance index, in contrast, we compare the measured energy output of a power plant to the energy output calculated with a potentially quite complex model. As such models try to accurately consider various loss factors, performance index actually reaches 100% once the plant delivers the amount of energy that is expected from the simulations. In IEC 61724-1, performance index is defined as the ratio of the measured AC energy to the expected AC energy.

温情杀手2020-05-15Performance ratio and performance index are standardized indicators defined consistently for nonconcentrator and concentrator PVs. Performance ratio, as defined for nonconcentrator systems in IEC 61724-1 and for concentrator systems in IEC 62670-2, is a measure expressed in percent, for the overall effect of losses on the power output of a plant.
