“…× 𝜂 𝑖𝑛𝑣. × 𝐴𝐶 𝐿𝑜𝑠𝑠 (7) The power efficiency curve for a selected PVI-10.0/12.5-TL-OUTD inverter, which can be found in the inverter's product handbook, illustrates in Figure 4(a). As a result, the power efficiency curve is a viable replacement for the extensive mathematical operations that are required to explain the inverter's mathematical model.…”

“…In addition, Oil, gas, and carbon-based conventional energy sources are no longer adequate to meet the demands of the world economy [5,6]. In fact, experts caution that non-renewable resources may run out as soon as 2040 if energy consumption continues at its current rate [7,8]. For instance, in Iraq country, the overall annual consumption is 38.46 billion kWh of electric energy, while the total annual energy demand is 75.45 billion Kwh [9].…”

The world restriction of fossil power sources reserves and its side effect on the environmental pollution have impelled strongly using the photovoltaic technology as alternative renewable energy sources. The essential problem is the difficulty of importing and installing solar panels without having a fully knowledge about its effectiveness in the climatic conditions of the university site. Hence, the motivation of this study is to investigate the operational efficiency of the PV system in the Iraqi environmental conditions by modelling, controlling, and simulating the system using MATLAB/Simulink program. The proposed model has been driven based on the principle mathematical equations that depict the behaviour of the PV solar system. The proposed model is designed to affect with the sunlight irradiance, ambient temperature, AC loss, DC loss, the temperature of the panels’ surfaces, and the efficiency of the used inverter. Preliminary results showed a strong correlation between sunlight irradiance and ambient temperature with the power generated by solar panels. Thus, these two parameters are chosen as the major inputs to the model. While, the electrical output power and the accumulative energy are set as the output of the simulated model. The study investigates the performance of the proposed model at the hottest day and coldest day throughout the year 2022. The results proved that the system generates more energy during the summer than in the winter due to the strength and a long period of the radiation falling on the ground during this season. Moreover, the investigation study evidenced that the system efficiency decreases as ambient temperatures increase. As the results, the cumulative energy during one day decreased by around 41.366% from the summer to winter. Finally, the authors recommend installing the suggested solar cell system in Iraq because its effectiveness was theoretically proved.

“…Traditional energy resources, such as coal, oil, and natural gas, necessitate sufficient capacity to sustain a balance between their availability and energy demand, as emphasized by Rosales-Calderon and Arantes [2]. Moreover, existing energy consumption patterns could potentially exhaust these nonrenewable resources in the ensuing decades [3]. Compelling interest in alterations to our energy paradigm also stems from issues relating to climate change, global warming, and energy security [4,5].…”

Geothermal energy, an efficacious and readily available resource, has emerged as a sustainable alternative poised to satisfy escalating global energy demands. This study undertakes a comprehensive analysis of low (heat below 100℃) and medium (heat between 100℃ to 150℃) enthalpy geothermal energy through a bibliometric approach and a literature survey, with an emphasis on the environmental and economic aspects. The methodological procedure encompasses: (i) systematic information processing and configuration, (ii) bibliometric assessment of the evolution and domains of the investigated field, (iii) evaluation of environmental and economic contributions, and (iv) Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis, facilitated by a Focus Group comprising experts from the energy sector. The research on low and medium enthalpy geothermal energy has been identified as an expanding field, with five primary areas of focus: sustainability, cascade systems, heat pumps, numerical modelling, and groundwater potential in geothermal systems. Italy, the United States, and Germany have been recognized as the leading contributors in terms of scientific production. Geothermal energy, from an environmental standpoint, aids the decarbonisation process, reducing reliance on fossil fuels and other renewable energy sources. Although initial investment costs are considerable, the financial recovery period is relatively short. The promotion of geothermal energy, alongside the active involvement of academia, corporations, and governments, bolsters energy and socio-economic development, thereby contributing to the achievement of the Sustainable Development Goals (SDG).
