“…The intensity of solar radiation directly correlates with the amount of energy generated by photovoltaic (PV) system. Many methods have been proposed to maximize solar energy absorption through PV, including reconfiguring the PV system [8,9], implementing a solar tracker system [10,11], and employing the maximum power point tracking (MPPT) concept [12][13][14].…”

The incremental conductance method is susceptible to overshoot, oscillation, convergence errors, and the inability to adapt to rapidly changing conditions; therefore, innovation is required to ensure that this algorithm operates efficiently. This study investigates how the incremental conductance algorithm can be modified to enhance its performance, particularly in situations involving rapid environmental changes. The algorithm's performance is evaluated through simulation and subsequently compared to conventional methods and incremental conductance methods developed by previous researchers to determine how much performance increase can be achieved using the modified algorithm. The simulation results show that the second improved technique may significantly eliminate oscillations during maximum power point (MPP) tracking while also speeding up the convergence time. The results reveal that the proposed algorithm achieves an efficiency of 98.83%, which is higher than the conventional and first modified algorithms, which have efficiency values of 92.04% and 97.84%, respectively. Therefore, the second modification outperforms the other algorithms in terms of oscillation and efficiency.

CubeSats require accurate determination of their orientation relative to the Sun, Earth, and other celestial bodies to operate successfully and collect scientific data. This paper presents an orientation system based on solar and magnetic sensors that offers a cost-effective and reliable solution for CubeSat navigation. Solar sensors analyze the illumination on each face to measure the satellite’s orientation relative to the Sun, while magnetic sensors determine the Earth’s magnetic field vector in the satellite’s reference frame. By combining the measured data with the known ephemeris of the satellite, the satellite–Sun vector and the magnetic field orientation can be reconstructed. The orientation is expressed using quaternions, representing the rotation from the internal reference system of the satellite to the selected reference system. The proposed system demonstrates the ability to accurately determine the orientation of a CubeSat using only two sensors, making it suitable for installations where more complex and expensive instruments are impractical. Additionally, the paper presents a mathematical model of a low-cost CubeSat orientation system and a hardware implementation of the sensor. The technology, using solar and magnetic sensors, provides a reliable and affordable solution for CubeSat navigation, supporting the increasing sophistication of miniature payloads and enabling accurate satellite positioning in space missions.

As the demand for energy increases and the cost of non-renewable resources continues to rise, many nations are working to find alternative sources of electricity before a crisis arises. This effort is focused on transitioning away from conventional energy sources and towards non-conventional ones. Energy from the sun is clean and available in natural quantities, which can reduce our dependence on fossil fuels on a large scale along with providing low-carbon solutions. By tracking the sun’s radiations, the photovoltaic (PV) panels could be directed in such a way that they collect high levels of sunlight. This article presents the design and performance assessment of a low-cost dual-axis solar tracking system based on Arduino. The main objective of this study is to show that the proposed solar-tracking system performs better a non-tracking system. A light sensor and two servo motors are also employed to move the solar panel toward a high-intensity light source. The software domain code was created using the C programming language using the Arduino IDE, which interacts with the Arduino board and its other connected devices. The performance of the prototype was assessed and compared to that of a stationary solar panel of the same rating. In this paper, the authors have highlighted the necessary techniques to build a low-cost solar tracker for extracting maximum photovoltaic energy using real-time data. In terms of power output, the results reveal that the tracking system surpasses the fixed solar panel, indicating increased performance at a reasonable cost. Therefore, the solar tracker has been proven to be very effective in capturing significant solar energy for solar harvesting applications.
