Effect of the Inclusion of Photovoltaic Solar Panels in the Autonomy of UAV Time of Flight

Abstract

Photovoltaic technology and unmanned aerial vehicles are both alluring areas with a lot of potential to explore. Consequently, they have an ability to adapt and progress when faced with new challenges, hence their wide range of applications. An auspicious combination between the two is born from the Unmanned Aerial Vehicles’ (UAVs) inability to to overcome some of its problems, namely the autonomy one. This article springs from the need to vanquish the problem, finding a more permanent solution. Its aim consists in the installation of solar photovoltaic panels in the structure of a UAV, with the objective of studying being its influence on the vehicle’s time of flight. To accomplish this, a theoretical study will be made, encompassing all the potential variables together with its influence. In order to verify the credibility of these claims, a prototype, based on the original aerial vehicle structure form and material, is constructed, using a finite element tool. Later, the prototype is used to evaluate possible harsh circumambient air to structure interactions, modeled by the fluid motion describer Navier–Stokes equations. For a smooth approach involving lighter computational power, a RANS model is used to asses the equations. Based on its results the chosen solar technology credibility is evaluated. A simulation of solar cells will also be carried out, accepting as input previously studied parameters which will modify its performance. Bearing in mind the produced results, it is concluded that the solar panels can only significantly augment the time of flight in very specific conditions.

“…where v h is the e velocity at the desired height Z h , v an is the velocity at the anemometer height Z an and z 0 is the surface roughness length, which is 0.005 m/s for the blown sea [13].…”

A Photovoltaic Technology Review: History, Fundamentals and Applications

“…The photovoltaic effect was first observed in 1839, by Alexandre Edmond Becquerel, a young French physicist. He was conducting electrochemical experiences, when he noticed the occurrence of this effect on silver and platinum electrodes, which were exposed to the sunlight [1][2][3].…”

“…They used selenium, and this device had an efficiency of approximately 0.5%. After one year, Charles Fritts doubled this efficiency, also using selenium but in a different approach: a selenium wafer between two metal thin layers [1][2][3].…”

“…In this first experiments, all these researchers and inventors reached a unique conclusion: the generated current is proportional to the incident radiation and this proportionality depends on the radiation wavelength. However, instead of being used as solar cells (due to its low efficiency), these devices were used as sensors [1][2][3]. An awesome example was the photography light sensors developed by the German engineering Werner Siemens, the founder of Siemens [2].…”

Wearable Photovoltaic Applications as Energy Sources for Everyday Devices

“…The perovskite solar cells can offer a potential solution to the problem at hand since it is possible to achieve a very generous efficiency to power such devices. Yang et al (2019); Zhang et al (2018); Isabela et al (2021); dos Santos et al (2021);Engana Carmo et al (2021).…”
