Abstract

This study explores the utilization of photovoltaic solar panels as a source of electrical energy to meet the needs in hard-to-reach areas. Using experimental methods, data were collected during observations from September 13 to September 18, 2024, encompassing measurements of voltage, current, and solar radiation intensity. The results indicate that the highest panel efficiency reached 25.12%, while the lowest was 19.25%, significantly influenced by sunlight intensity and panel temperature. Additionally, the highest convective heat transfer coefficient was recorded for Panel 1 at 96.64 W/m²K, showing a direct relationship with thermal conditions. This research emphasizes the importance of system design and the management of environmental factors to enhance panel efficiency. These findings open opportunities for the development of cooling technologies and more efficient energy conversion in the future.

Abstract

This study evaluates the impact of RON 90 and RON 92 fuels on the performance of a 4-stroke engine with a capacity of 2800 Watts. In the applied methodology, a 2800 Watt two-wheeler vehicle was used to test torque, power, and specific fuel consumption (SFC) at various engine speeds. The results show that RON 92 has better torque at 4000 RPM, while RON 90 exhibits higher torque at speeds approaching 7500 RPM. Power analysis indicates that both fuels produce the same maximum power of 8.7 HP, although it is achieved at different engine speeds. Meanwhile, in terms of SFC, RON 92 is more efficient at lower speeds, but the difference narrows at higher speeds. These findings provide insights into the performance of both types of fuel and their use in engine applications.
