In the past years there has been several studies that compare the energy produced by solar panels that are installed traditionally on the roofs of buildings, to when the panels are installed on the facades of buildings. This allows for using a different approach when planning the installation of such solar panels and it can be done by combining modern mobile devices and AR. This report describes the work done for improving the SolAR project, an AR solution developed for tablets with the Android operating system. This application allows the visualization of solar radiation data in AR, as well as the simulation of placement of solar panels on the buildings facades and displaying information regarding its cost and energy efficiency. The initial plan for the project was to reuse parts of code and algorithms that were already implemented in the previous version of the App, but this was abandoned due to the existing limitations that prevented the generalized usage of the App, since it can only be used on Android tablets and requires calculation in advance of solar radiation data for the buildings. So instead of that a new approach was used, implementing the core functionalities of the old App, but eliminating the existent limitations. After the development phase was completed, the next stage was to test the application and obtain user feedback. The SUS (System Usability Scale) for the App resulted in a score of 64, indicating moderate usability, with specific recommendations to improve user instructions, interface intuitiveness, and overall interaction ergonomics.application/pdfengAugmented RealityVisualizationSolar EnergyUnity 3DMobile Devicesmaster thesis204122333
