“…Zhong H et al [7] set three directions in a day in China to obtain the most solar radiation. This research was similar to the ideas in [5], [6]. Bahrami A et al [8] believed that while considering the benefits of dual-axis tracking, economics should also be considered to achieve the best overall benefits.…”

The study focuses on the performance comparison of solar single-axis tracking lowconcentration photovoltaic/thermal (LCPV/T) system with different axes. The axes of the single-axis tracking LCPV/T systems are arranged along the east-west (EW) axis, north-south (NS) axis, and southeast 18° (SE-18°) axis, respectively. The thermal performance of the single-axis tracking system with different axes is discussed through simulated and experimental methods. Simulation study shows that the EW tracking system receives the highest amount of radiation and produced highest electrical energy throughout the year. The experimental research demonstrates that low-concentrating technology significantly improves the performance of the system. Chiefly, the overall thermal efficiency maintains between 50%-70%, and the maximum thermal efficiency achieved in the experiment reaches 68%. The average overall efficiency and exergy efficiency of the NS axis, EW axis and SE-18° axis are 59% and 20%, 64% and 23%, 59% and 20%, respectively. Both the energy and exergy performance of the EW axis is better than the other two axes. The placement of the axis has a significant impact on the thermal and electrical performance of the LCPV/T system. Consequently, the combination of low-concentrating and single-axis tracking technologies has an excellent prospect in practical application.

“…During sunny weather, per m 2 solar panel produces daily average energy conversion higher than 6 kWh/m 2 . Whereas when the weather is not clear, the energy produced is not as much when the weather is sunny, i.e., less than 5 kWh/m 2 [5]. The uncertainty of the power produced by this photovoltaic can disrupt the continuity of electricity distribution.…”

<p>Solar power plants using environmentally friendly technology in the process of harvesting energy from the sun can be a solution to the future electricity crisis so that it has been the most widely developed and reliable alternative. However, the conversion of solar energy depends on the availability and conditions of sunlight. In sunny conditions, the PV system can serve large loads while charging the battery to the maximum. While in cloudy weather conditions or at night, the PV system serves the load and without charge of the battery. The battery will discharge the stored energy until it runs out, and the supply to the load will be cut off before the desired time. Therefore, research on the PV system loading management system is needed to increase the amount of electricity from solar energy and maintain the continuity of electricity supply to the load. The load power management strategy follows the conditions of sunny, cloudy, rainy, or night time by considering the remaining capacity of the battery that can be used. Load installations are designed to consist of low, medium, and high load installations. Simulation results show that the use of PV loading management strategies can increase the operating time of the PV system. When the remaining less than 10% battery capacity and PLN supply is available, the supply will be switched to PLN. The remaining 10% of PV battery capacity could be used to maintain electricity supply to a low load if the PLN supply interrupted. Thus, the use of a loading management strategy will increase the electricity supply from renewable energy and improve the sustainability of electricity supply.</p>

Solar energy is a feasible and efficient way to reduce environmental pollution which, in turn, can decrease the production of greenhouse gases. Iran with over 300 sunny days has a high potential for producing energy, including electricity through photovoltaic (PV) systems. Regarding this fact that Iran has the enormous resources of fossil fuels such as oil and gas, the government tends to expand its energy production by renewable systems, including photovoltaics. This paper is to evaluate the efficiency of photovoltaic system in one of the major provinces of Iran. In this study, a 4.8 kW photovoltaic power station in East Azerbaijan province was investigated. First, a simulation-analysis is carried out. Then the verification of the study is done using extracted experimental data. According to the results, the photovoltaic power plant generates 8334 kWh annually. Finally, the station is economically investigated. This economic analysis is carried out in accordance with the existing tariffs and policies in Iran.
