The work of solar cells and their production of electrical energy have been affected by climate change, especially in hot regions which became significantly hotter and still receive relatively high levels of solar radiation throughout the year. Higher ambient temperature and solar radiation result in higher PV cell temperature and, therefore, the reduction in PV module power output and efficiency. This study investigates how a PV module performs throughout the year in a hot region by considering the variations in cell temperature resulting from changes in ambient temperature and solar radiation every day. The tilt angles and two-axis tracking have also been examined. Results indicate that the two-axis solar tracking system is critical to use in hot regions for obtaining higher output power. Therefore, part of this power can be used to cool solar panels using various methods to keep their efficiency high, such as operating air fans or operating pumps to cool them with coolant.

“…The controller was compared with a fixed-angle PV system and the results confirmed the superiority of the proposed method. In [93], an ultraviolet (UV) sensor-based dual-axis solar tracking system was presented. For validation, the proposed technique was compared to a fixed-angle system and a light-depended resistors (LDRs) based solar tracking system.…”

The use of computational intelligence (CI) in solar photovoltaic (SPV) systems has been on the rise due to the increasing computational power, advancements in power electronics and the availability of data generation tools. CI techniques play an important role in modelling, sizing, forecasting, optimizing, analysing and predicting the performance and control of SPV systems. Thus, CI techniques have become an essential technology as the energy sector seeks to meet the rapidly increasing demand for clean, cheap, and reliable energy. In this context, this review paper aims to investigate the role of CI techniques in the advancements of SPV systems. The study includes the involvement of CI techniques for parameter identification of solar cells, PV system sizing, maximum power point tracking (MPPT), forecasting, fault detection and diagnosis, inverter control and solar tracking of SPV systems. A performance comparison between CI techniques and conventional methods is also carried out toprove the importance of CI in SPV systems. The findings confirmed the superiority of CI techniques over conventional methods for every application studied and it can be concluded that the continuous improvements and involvement of these techniques can revolutionize the SPV industry and significantly increase the adoption of solar energy.

One of the problems with solar power plants is the angle of inclination at the time of installation. Errors in determining the angle would make solar power plants do not produce power optimally. To maximize the power generated by solar power plants, the tilt angle of the solar panel must be adjusted so that it faces directly towards the sun. This research designs a dual-axis solar tracker using a microcontroller, LDR sensor, and servo motor. In addition, the influence of the number of sensors and tracking delay is analyzed to determine the output power of solar panels with different configurations. Testing from 7:00 am - 5:00 pm, where there are 2 days of testing, 2 days of tracking delay testing and 3 days of testing 3 solar panels installed, first dual-axis solar tracker, the rest with 0° and 30° tilt angles. The results of the dual-axis solar tracker design on the x-axis can rotate from 0o to 20o, while the y-axis can rotate from 35° to -17°. Testing using 4 LDR sensors affects the angle change of the solar panel. Tests show tracking delays every 30 minutes and 1 hour have no significant effect. The power generated at a tracking delay of every 30 minutes is greater, but the power consumed is also greater. During the test, it was found that the 1-hour tracking delay produced 1.76% more net power. The last test of dual-axis solar tracker and solar power plant with tilt angles of 0° and 30°. During the test it was found that the dual-axis solar tracker produced 16.89% more power than the 30° tilt angle and 11.42% more than the 0° angle.
