“…The abscissa represents the total irradiation amount of the day, the ordinate represents the PRstc value, PRstc1 is calculated according to the standard method, and PRstc2 is calculated according to the method in this paper. The difference between the two PRstc values is less than 2% when the total irradiance is greater than 6kWh/m 2 , and the difference may be caused by the fitting error of the model and the low irradiance during the day and night alternation [17] . When the total daily irradiation is less than 6kWh/m 2 , the difference increases with the decrease of irradiance.…”

The performance ratio (PR) of the system is used to quantify the power generation efficiency of the photovoltaic power generation system. The size of the index is affected by many factors. After the environmental impact is compensated, the standard energy efficiency ratio (PRstc) of the system is obtained. PRstc is an important index for evaluating the power generation efficiency of photovoltaic power stations. Improving the accuracy of PRstc is conducive to improving the state evaluation and analysis capabilities of power stations, providing a theoretical basis for comparative analysis of photovoltaic power stations in different regions, and improving the scientific operation and maintenance of power stations. The PRstc calculation method of the industry standard NB / T 10394-2020 does not consider the influence of the change of the power temperature coefficient of the component and the weak light response of the photovoltaic cell, which ultimately leads to the calculation result less than the actual value. In order to reduce the error in the calculation of PRstc, the mathematical relationship between PR and power loss of photovoltaic power station is discussed. The calculation method of power loss caused by the change of environmental factors is proposed, and the PRstc is calculated by using the variation. Finally, the PRstc is calculated according to the actual operation data of photovoltaic power station, and compared with the calculation method of industry standard NB / T 10394-2020. The results show that when the total irradiation dose is high, the difference between the two PRstc values is less than 2 %. When the total irradiation is low, the calculation result is larger than that of the standard method, and the difference between the two increases with the decrease of the total irradiation. Due to the consideration of the change of power generation caused by the characteristics of photovoltaic modules, the error caused by the change of power temperature coefficient and weak light response of modules is reduced, which is more advantageous than the calculation method of industry standard.

The growth of populations and economy in Northern Cyprus has led to continuing utilization of fossil fuels as the primary source of electricity, which will raise environmental pollution. Thus, utilizing renewable energy, particularly solar energy, might be a solution to minimize this issue. This paper presents the potential of grid-connected solar PV power generation at Near East University Hospital (NEU Hospital), one of the largest and leading medical facilities in Northern Cyprus, to meet the energy demand during the daytime to reduce energy bills. For this purpose, the first objective of the study is to evaluate the solar energy potential as a power source for the NEU Hospital based on four datasets (actual measurement, Satellite Application Facility on Climate Monitoring (CMSAF), Surface Radiation Data Set-Heliosat (SARAH), and ERA-5, produced by the European Centre for Medium-range Weather Forecast). The results showed that the solar resource of the selected location is categorized as excellent (class 5), that is, the global solar radiation is within the range of 1843.8–2035.9 kWH/m2. The second objective is to investigate the impact of orientation angles on PV output, capacity factor, economic feasibility indicators, and CO2 emissions by using different PV modules. The results are compared with optimum orientation angles found by Photovoltaic Geographical Information System (PVGIS) simulation software. This objective was achieved by using RETScreen Expert software. The results demonstrated that the highest performance of the proposed system was achieved for orientation angles of 180° (azimuth angle) and −35° (tilt angle). Consequently, it is recommended that orientation angles, PV modules, and market prices are considered to maximize energy production and reduce electricity production costs.
