Abstract

Overheating can significantly reduce the efficiency and power output of solar panels, leading to the development of various cooling techniques. This paper compares four cooling methods: heatsink with fan, fin heatsink, water cooling, and floating solar panels. The study evaluates these methods based on temperature reduction, cooling efficiency, electrical performance, and practical considerations. Active systems, like water cooling and heatsink with fan, showed higher performance improvements but required more resources and were more complex to operate. On the other hand, passive systems such as fin heatsink, and floating panels offered simpler and more sustainable solutions with moderate efficiency gains. This review highlights the balance between efficiency, sustainability, and practicality, providing valuable insights for choosing the best cooling method for solar panels. The findings also point to future opportunities for advancements through hybrid systems and new materials to enhance performance and sustainability in solar energy systems.

Abstract

The Archimedes wind turbine is a promising technology for renewable energy applications in low wind speed conditions, yet the optimization of the blade geometry still requires a comprehensive investigation. This study aims to analyze the effect of variations in the number of blades (three and four) and pitch angles (50°, 55°, 60°, and 65°) on the aerodynamic performance of Archimedes wind turbines using the ANSYS 2024 R1 Computational Fluid Dynamics (CFD) simulation. The research methodology applied the SST turbulence model k-ω with a constant Tip Speed Ratio (TSR) at a value of 1 to isolate the influence of geometric parameters on the coefficient of power (Cp). The simulation was carried out with a residual convergence criterion of 0.001 throughout 1000 iterations until a stable solution was reached. The results of the analysis showed that a four-blade configuration with a pitch angle of 65° resulted in an optimal Cp of 0.2027, representing an 85.6% performance improvement over the three-blade configuration of 50° (Cp = 0.1092). Velocity and pressure contour visualization revealed that the four blades demonstrated superior attachment flow, a more even distribution of pressure differential, and an organized wake structure that minimized energy dissipation. The study's conclusions identified a four-blade configuration at a pitch angle range of 60-65° as the optimal design for Archimedes wind turbine applications in low wind speed conditions, making a significant contribution to the development of renewable energy technologies for urban and tropical regions.

Abstract

Archimedes Spiral Wind Turbines (ASWTs) are suitable for small-scale energy harvesting in low wind environments.However, field-based evaluation on the effect of blade number under natural wind conditions remains limited. This study experimentally examines the influence of blade number on rotational behavior and electrical performance under natural wind conditions, providing empirical insights beyond controlled laboratory and numerical studies. Three-bladed and four-bladed turbine configurations were fabricated and tested in field conditions with wind speeds ranging from 0.8 to 4.0 m/s. Wind speed, rotational speed, voltage, current, and electrical power were measured and analyzed.  The results show that the four-bladed turbine achieved earlier cut-in behavior and consistently higher electrical output across the tested range, reaching a peak power of approximately 0.29 W at wind speeds of 4.0 m/s, compared with about 0.09 W for the three-bladed configuration. The improved performance was attributed to enhanced torque continuity and rotational stability rather than increased rotational speed alone. Transient current peaks and zero-current events observed near 1.5 to 2.0 m/s were attributed near-cut in electromechanical behavior under short-term wind fluctuations. These results confirm that blade number significantly affects ASWT performance in low wind environments and provide practical guidance for optimizing small-scale wind turbine design.
