“…Furthermore, improving the efficiency of the entire PV system, including inverter, battery, etc., was also the subject of many studies. For example, Ketjoy et al (2021) studied three parameters affecting the efficiency of PV inverters. The first parameter was the duration of operation and the investigation of an inverter that worked for 4 years showed that its efficiency decreased negligibly from 91% of the manufacturer's specification of 90%.…”

This study investigates the current status of photovoltaic water pumping systems (PVWPSs) in Iran, a country endowed with significant solar irradiation potential, notably in its southern and central regions. Despite this potential, there is a scarcity of comprehensive studies on solar water pumping systems within the country. This purpose of this study is to conduct a thorough review of the existing literature to assess the state of solar water pumping in Iran. The adoption of PVWPS across various provinces demonstrates the system's versatility, proving effective in both highly sunny and less irradiated regions. Iran's widespread utilization of PVWPS is attributed to its ample irradiations, even in its northern areas, which possess lower solar irradiance levels. There are limited comprehensive studies encompassing technical, economic, environmental, and social aspects of solar PV water pumping projects in Iran. Most of the research has been conducted during the last few years, indicating an increased recognition of the possible advantages of this technology. Finally, this review provides valuable insights for researchers and farmers, showcasing the benefits of solar PVWPS. It sets the stage for further innovation and implementation in the country's agricultural landscape, emphasizing the need for continued exploration and adoption of this sustainable approach.

Energy security refers to a country’s capacity to provide the energy resources essential to its wellbeing, including a reliable supply at an affordable costs. Economic growth and development cannot occur without access to reliable energy sources. Energy availability is a proxy for a country’s standard of living and a key factor in its economic development and technical progress. Solar power is the most reliable and cost-effective option when it comes to meeting the world’s energy needs. Solar-powered cooling systems are one example of how solar energy may be used in the real world. Solar-powered air conditioners have become more popular in recent years. The problems caused by our reliance on fossil fuels may be surmounted with the help of solar cooling systems that use solar collectors. Solar cooling systems may utilize low-grade solar energy, making them popular in the construction industry. Solar cooling systems powered by photovoltaic–thermal (PVT) collectors have been the subject of much research to improve the thermodynamic and economic performance of solar cooling systems. This research focuses on exploring the potential of solar-generated heat for use in cooling systems. This study will also examine the current challenges involved with using solar energy in cooling applications, as well as the possible benefits that may help pave the way for more research and greater employment of heat gain from the solar system in various cooling applications.

“…For each of their MPPT, these inverters can operate up to a maximum voltage of 1000 V. The nominal operating voltage of each power tracking is 600 V and ensures the efficient operation of the PV inverter [47]. The minimum voltage level required for the inverter to operate is 188 V. The maximum current allowed at the input of each of its MPPT is 33 A.…”

This research is based on achieving modular solutions for photovoltaic solar systems (PVSS) in buildings. Several studies tend to inadequately address the analysis of photovoltaic (PV) module orientation, often relying on the conventional south-facing orientation. The objective is to analyze and compare the influence of PV module orientation. Therefore, two proposed PVSS were analyzed, incorporating module orientation and inclination variations. A hotel electrical consumption study was conducted in 2018-2019. The incidence of shadows over the roofed surfaces of the building was analyzed from a three-dimensional model using Sketchup software. The annual and monthly generation, as well as the performance of the installation, were estimated using PVsyst software for each projected arrangement. An economic and environmental study was carried out for these proposals to remark on their feasibility and influence on environmental protection. As a result, the east-west oriented PV system is the most efficient and feasible with a peak power of 113.24 kW p and a Performance Ratio (PR) of 0.80. The east-west oriented proposal allows avoiding emissions of 301 421 TCO 2 into the atmosphere. These promising results were due to both PV modules physical orientation and their lower daily working temperature. Also, an increase in electrical production per module and an optimization of the surface are achieved. These results highlight the significance of this research as they encourage the adoption of these systems, leading to improved investment recovery periods and enhanced environmental conservation efforts.INDEX TERMS renewable energy technologies; electricity; photovoltaic solar system; efficiency building roofs.
