The energy generation demand from environmentally friendly sources is increasing rapidly nowadays. One of the most essential renewable energy systems in this regard is the photovoltaic (PV) module. However, this technology accompanies several limitations, including the ground footprint and tilt angle sensitivity. In this study, the PV module shape has been modified to enhance the productivity of the PV system. The proposed PV module with a hemispherical shape is established to reduce the land cost and provide a perpendicular PV area exposure to the sun all day to harvest sunlight and generate more power without any supporting system. Besides, the proposed hemispherical shape has advantages in aesthetic terms of the PV system to enhance the flat black shape of this technology. The current paper also attempted to develop a new design of a curved PV hemispherical shape that needed less land footprint than the traditional flat shape by 19%. The experimental results showed that the tilted 45° hemispherical PV module generated more power than the conventional tilted PV module by 5%–6% per day in summer. Besides, the power line behaviour was more likely to be as the power generated from the traditional PV module with a tracking system.

This research article investigates the advantages of using solar power as a source of energy for potential automobiles. Solar energy is considered in this work for the seek of reducing greenhouse emissions. The study is carried on an electrical vehicle (EV) with a 6.1m2 solar module. This solar module gives an average power output of 4.8 kW h / day over 90 days under real-world conditions. Innovative statics have been studied to help reduce the solar module installation area on the vehicles, which is essential for passenger vehicles in practice. A 15% increase in the vehicle's operating default time was obtained in addition to the other features of this vehicle. Both External appearance and efficiency for the modified vehicle are discussed in this paper.

In pursuing advancing solar energy systems, this research uniquely occupies a position at the intersection of photovoltaic (PV) efficiency, innovative design and aesthetic integration into urban landscapes. This study explores the potential of thin solar cells applied to spherical and hemispherical surfaces and the influence of temperature variations throughout the day. By conducting a comprehensive analysis of voltage–current diagrams, the study deciphers the intricate interconnections of spherical geometries and their response to external thermal impacts, elucidating their subsequent effects on energy conversion efficiency. Moreover, it delved into the dynamics of connecting multiple spherical modules, unveiling their potential to form artistic and utilitarian constructs such as solar trees and architectural embellishments. The findings indicate that while spherical configurations provide superior aesthetics and a power generation profile comparable to solar tracking systems, hemispherical configurations offer a 32% increase in efficiency compared with the spherical configuration and a notable reduction in land footprint. This research underscores the importance of striking a balance between aesthetic appeal, efficiency and land utilization, providing valuable insights for the future of PV technology integration into urban and agricultural landscapes.
