Energy is a key component of socioeconomic development, and electricity in particular has become essential to industrial and social processes. The need for energy has increased dramatically over the last few decades; it is expected to reach 73,000 TWh by 2050 and rise at a 3.1% yearly pace [1]. Historically, fossil fuels like coal, oil, and natural gas have been the main source of power. These fossil fuel reserves are limited, though [2], and generating power from them emits a significant amount of greenhouse gases (GHGs) [3], endangering the ecosystems and the surrounding environment. The transition to cleaner and renewable energy sources is required for the sustainable production and consumption of energy.
In order to meet future energy demands and reduce environmental impact, alternative and renewable energy sources such as solar, wind, biomass, and others are essential [4]. As a result, a number of nations are working hard to raise the share of renewable energy in their mix of power generation. When it comes to renewable energy, solar photovoltaics (PV) is leading the way due to its increased solar cell efficiency, less production costs [5], and ease of installation in comparison to other renewables. Once placed, PV panels begin producing electricity instantly. Furthermore, the globe receives around \(\text{3,8}\times {10}^{14}\) kW of solar energy each second, indicating the free and plentiful availability of solar energy [6]. Because solar PV has a short payback period, it has proven to be a lucrative industry that has drastically lowered the LCOE [7]. The International Renewable Energy Agency (IRENA) estimates that at the end of 2018, the installed capacity of solar PV worldwide had reached 480.3 GW, and by 2025, it is expected to climb to 969 GW [8]. With 746.46 GW of installed capacity, Asia now has the highest share of PV installations.
The Algerian government, like the majority of developing nations, has developed the "National Program for Renewable Energies and Energy Efficiency" as a doable first step in the direction of sustainability. By 2030, 40% of Algeria's electricity demands are expected to be supplied by renewable energy, according to the country's national program [9]. Due to its considerable sun exposure, which covers 90% of the nation across an area of 2,382 million k\({m}^{2}\), it has committed to obtaining the bulk of its renewable energy supply from solar photovoltaics (PV) [10]. According to [11], the expected amount of sunshine is 3000 hours per year, and the daily energy can reach up to 5 kWh/\({m}^{2}\).
Examining the effectiveness of photovoltaic (PV) systems in diverse settings while taking into account many influences has been a subject of research. For example, [12] used real performance metrics to track a photovoltaic system in Tangier over the course of a year. The PV system's efficient operation was shown by the capacity factor of 14.83% and the yearly performance ratio of 79%. In a similar vein, [13] examined the operation of a 50 MW PV project in southern India using SCADA data from April 2018 to March 2019. The capacity utilization factor and yearly average performance ratio yielded figures of 24.65% and 79.94%, respectively. In order to evaluate the quality of substantial amounts of data for a more precise research of PV system performance, the authors of [14] carried out the first performance analysis of time series databases of PV systems deployed in Europe. Comparative research between the simulated and measured approaches is therefore required. [15] in Malaysia concentrated on utilizing a straightforward model and measurements to determine the desired performance. The target-oriented model's dependability was proven by the earlier investigation. After 12 years of operation, a grid-connected photovoltaic facility in central Spain was evaluated by [16] utilizing on-site data for 2020 and two additional modeling approaches the physical model and the statistical model based on the random forest method. When metric parameters were included, the random forest algorithm technique produced good results using simply ambient temperature and sun radiation as inputs. Using both measured data and the PVGIS database, the research [17] assessed the Zagtouli Grid-Connected Solar Power Station (ZGCSPS)'s performance.
However, research on evaluating large-scale PV systems in Algeria by comparing measured and simulated performances is limited. This study aims to compare the measured performance values of the Dhaya photovoltaic plant in Sidi Bel Abbess for the year 2023 with values simulated by both PVSyst and Solar GIS-PV Planner. This comparison will allow us to assess the reliability of sizing software in the region to predict production and performance parameters, thereby facilitating the installation of other photovoltaic plants in Algeria. The comparison focuses on various performance indicators such as performance ratio, capacity factor, energy production, temperature, and irradiation.
