Résumé
Thin-film solar photovoltaic (PV) cells are among the modern clean energy technologies. In addition, it has many advantages that facilitate its integration with the building envelope and thus contributes to improving buildings’ energy and environmental performance. This research aims to techno-economically investigate the application of this technology on commercial building facades in the Kingdom of Saudi Arabia. In this research, many axes of thin-film PV’s application on commercial building facades are discussed, covering their key technical and economic performance indicators. The research approach involves building modelling and PV simulation, survey of key stakeholders, and application of machine learning. With regard to the performance of the cells, several scenarios have been considered, including the height and width of the building, and the distance from the neighboring buildings. Results show that the appropriate elevation angle should not be more than 64 degrees, in order to achieve 90% or more of the amount of energy produced in the absence of obstacles. With regard to the width of the building, it is concluded that the width ratio of 90 degrees is suitable to produce 90% or more of the original capacity in the absence of any obstacles. Economic analysis reveals a levelized cost of electricity (LCOE) to be equivalent to 0.07 $/kWh. With financial support economic viability can be significantly improved. In case governmental incentives are applied with a percentage of 30%, the LCOE could be reduced to 0.04 dollars per kilowatt. Machine learning analysis helps optimize the performance prediction of PV systems.
