Experimental validation of different PV power prediction models under Beni Mellal climate, implications for the energy nexus

Abstract

Analyzing the efficiency of Photovoltaic installations in real situations is a difficult task, as there are many models and software packages available. Generally, software and models cannot predict Photovoltaics output under all weather and geographic conditions. It is necessary to develop a protocol to assess the viability and profitability of potential Photovoltaic installations based on a real-world system. In this paper, analysis of the performance of a photovoltaic system is carried out and the production of 3 Photovolatic prediction models was evaluated, and their accuracy was compared to one year of actual measurements of an monocristalline silicon Photovoltaics grid-connected plant. The results show that models M1, M2, and M3 are all adequate to simulate Photovoltaic performance in the climatic conditions of the Beni Mellal region with an advantage for the M1 model.
