Abstract
This work analyses the performance of a photovoltaic (PV) power plant with an output capacity of 20 megawatts (MW), which is located in the region of Ain El-Melh, Algeria. The present assessment is founded on experimental data collated between January and December 2019. The plant consists of 40 sub-fields, each equipped with a 500 kW inverter and 1936 PV modules of 250 Wp each. A range of performance parameters are analyzed, including, reference yield, final yield, module and system efficiency, performance ratio (PR), corrected PR, and other loss-related indicators.
In this study analyze the performance of this plant in 2019 using new method of corrected tilt radiation data (Gm,corr). The corrected tilt radiation improves the accuracy of key performance metrics, including yields, efficiencies, and losses, offering a clearer picture of the plant’s efficiency in a high plateau climate.
