The performance ratio is a measure of the quality of a PV plant that is independent of location and it therefore often described as a a quality factor. The performance ratio (PR) is stated as percent and describes the relationship between the actual and theoretical energy outputs of the PV plant.
Additionally, consistently low modal damping ratios were measured, ranging from 1.07 % to 2.99 %. Secondly, modal analysis of the tracking photovoltaic support system was performed using ANSYS v2022 software, resulting in the determination of structural natural frequencies and mode shapes.
Key findings are as follows. Dynamic characteristics of tracking photovoltaic support systems obtained through field modal testing at various inclinations, revealing three torsional modes within the 2.9–5.0 Hz frequency range, accompanied by relatively small modal damping ratios ranging from 1.07 % to 2.99 %.
Standards available for the energy rating of PV modules in different climatic conditions, but degradation rate and operational lifetime need additional scientific and standardisation work (no specific standard at present). Standard available to define an overall efficiency according to a weighted combination of efficiencies.
This anticipated nominal plant output corresponds to a performance ratio of 100 %. However, the actual value for electrical energy exported by the PV plant to the grid is only 110 kWh. If this value and the calculated nominal plant output are fed into the formula for calculating the performance ratio, the following result is obtained:
SAM’s photovoltaic performance model calculates the hourly AC output of the photovoltaic system. It then adds up these 8,760 hourly values to calculate the system’s total AC output in one year. This value is treated as the system’s total output in the first year of the system’s operation.
