This standard outlines requirements for measuring equipment (sensors), methods, and terminology for performance monitoring and analysis of photovoltaic (PV) systems. In addition, it serves as a basis for other standards which rely upon the data collected, such as 61724-2 and 61724-3.
The average energy ratio of 74.6% is close to the median of 76.0%, confirming that the distribution is not dominated by the outliers. It is unrealistic to assume the PV systems will deliver 100% of the model-estimated performance due to the associated maintenance, staff time and attention, and expense required.
For PV system performance assessment, electrical and environmental measurements are measured. This standard defines a procedure for measuring and analysing the power [W] production of a photovoltaic system with the goal of evaluating the quality of the PV system performance.
Deline et al. (2020) reported on the performance of 250 PV systems throughout the United States, comprising 157 megawatts (MW) direct current (DC) capacity, to have an average PR of 93.5%.
The new IEC 61724 “Photovoltaic system performance” series of standards is the best available source that defines parameters such as “performance ratio” and “performance index”. The purpose of this document is to clarify the logic behind IEC 61724 and its vocabulary. For brevity sake we do not mention all parameters and performance metrics.
Example Table Documenting the Meteorological Input Parameters to the The power generation of a photovoltaic (PV) system may be documented by a capacity test [1, 2] that quantifies the power output of the system at set conditions, such as an irradiance of 1000 W/m2, an ambient temperature of 20°C, and a wind speed of 1 m/s.
